DETAILED DESCRIPTION
In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.
Breastfeeding and human milk are considered the normative standards for infant feeding and nutrition. See, e.g., American Academy of Pediatrics (2012) “Breastfeeding and Use of Human Milk,” Pediatrics 129:e827-e841, which is incorporated herein by reference. Short- and long-term benefits of breastfeeding on health have been documented and include reduction in the incidence of gastrointestinal tract infections, respiratory tract infections, otitis media, necrotizing enterocolitis, sudden infant death syndrome, allergic disease, celiac disease, inflammatory bowel disease, obesity, and diabetes. However, in some instances, breast milk may not provide the optimal nutrition to the infant. In such cases, supplementation may be recommended or required. Described herein are devices, systems, and methods for providing supplements to a nursing infant during breastfeeding.
With reference now to FIG. 1A , shown is an example of a breast milk supplement delivery device 100 , which can serve as a context for introducing one or more processes and/or devices described herein.

For example, the breast milk supplement regimen can include one or more breast milk supplements, e.g., micronutrients or minerals, deficient in the breast milk of the lactating female. For example, the breast milk supplement regimen can be personalized to include one or more vitamins lacking or deficient in breast milk, e.g., vitamin D (recommended 400 international units per day) and/or vitamin K (recommended 25 micrograms per day; see, e.g., Committee on Fetus and Newborn (2003) “Controversies concerning vitamin K and the newborn. American Academy of Pediatrics” Pediatrics 112:191-192 which is incorporated herein by reference). For example, the breast milk supplement regimen can include added n-6 and n-3 fatty acids, e.g., linoleic acid, arachidonic acid, and/or DHA, potentially deficient in the breast milk of a lactating female with a specific diet, e.g., a low fat, vegetarian, or vegan diet. See, e.g., Innis (2007) “Human milk: maternal dietary lipids and infant development,” Proc. Nutr. Soc. 66:397-404, which is incorporated herein by reference. In an aspect, the breast milk supplement regimen is personalized based on a microbial quality of the breast milk of the lactating female. For example, the breast milk supplement regimen may be designed to add microbes, e.g., probiotics such as bifidobacterium , that might be underrepresented in the breast milk of the lactating female. See, e.g., Hunt et al (2011) “Characterization of the diversity and temporal stability of bacterial communities in human milk,” PLoS ONE 6(6):e21313, which is incorporated herein by reference. For example, the breast milk supplement regimen may be designed to add microbes, e.g., microbes of Leuconostocaceae and/or Staphylococcaceae bacterial families, that are underrepresented in breast milk from a lactating female choosing elective cesarean section versus vaginal or non-elective cesarean section. See, e.g., Cabrera-Rubio et al. (2012) “The human milk microbiome changes over lactation and is shaped by maternal weight and mode of delivery,” Am. J. Clin. Nutr. 96:544-551, which is incorporated herein by reference. In an aspect, the breast milk supplement regimen is personalized based on an immunological quality of the breast milk of the lactating female. For example, the breast milk supplement regimen may include added immunoglobulin A in a lactating female with an immunoglobulin A deficiency. Reduced immunoglobulin A in colostrum and breast milk of the lactating female may predispose an infant to develop food allergies. See, e.g., Jarvinen et al. (2000) “Does low IgA in human milk predispose the infant to development of cow's milk allergy?” Pediatr. Res. 48:457-462, which is incorporated herein by reference.
In an aspect, the breast milk supplement regimen is adjustable. In an aspect, the breast milk supplement regimen is adjustable based on a change in at least one of an attribute of an infant and a quality of breast milk of the lactating female. For example, the infant's nutritional needs may change as the infant ages and/or gains weight.

Various non-limiting embodiments are described herein as Prophetic Examples.
Prophetic Example 1: Smart Patch to Deliver Breast Milk Supplements
An embodiment of a breast milk supplement delivery device designed to adhere to a nursing mother's breast, deliver breast milk supplements, and to control the amounts of supplemental nutrients received by an infant is described. In this non-limiting example, the breast milk supplement delivery device takes the form of a flexible patch constructed with reservoirs, ports and valves to control the delivery of breast milk supplements to an infant. Electronic microcircuitry and microprocessors are incorporated in the flexible patch to control nutrient delivery according to a breast milk supplement regimen encoded in the device memory. Moreover the flexible patch includes: a transceiver to report a delivery event and to receive breast milk supplement regimen programs. Analyte sensors on the flexible patch detect supplements and metabolites in the infant's saliva and the mother's milk; analyte data is processed and used to adjust the breast milk supplement regimen, e.g., dosage, schedule, and composition.
A flexible, adherent breast patch that incorporates breast milk supplement reservoirs with valves to control the flow of supplements from the breast patch is based upon a multilayer polymeric substrate. A skin-adhesive first layer of the breast patch is cast using an acrylate copolymer dissolved in a volatile organic solvent which is subsequently evaporated to leave a planar, pressure sensitive adhesive patch. For example, an acrylate copolymer adhesive, dissolved in ethyl acetate may be cast as a donut-shaped patch that adheres to skin surrounding a breast nipple (see FIG. 2D ). A second layer of polymer, e.g., polyurethane, is cast in a donut shape to overlay the adhesive first layer. (See e.g., U.S. Patent Application No. 2003/0152612 by Pugliese et al. published on Aug. 14, 2003 which is incorporated herein by reference.) The polyurethane layer is cast with reservoirs which are embedded in sectors of the circular layer. Each reservoir is equipped with a conductivity meter to monitor the level of supplement in the reservoir. A thin film conductivity sensor approximately 1.5 cm in length is available from Innovative Sensor Technology USA, Las Vegas, Nev. (see the Info Sheet: Conductivity Sensor LFS155). The capacity of each reservoir is approximately 0.5 mL, and each reservoir has a port which permits influx or efflux of liquid supplements. Flow at each reservoir port is controlled by an electroactive polymer valve which is responsive to a microprocessor/controller. For example, an electroactive polymer valve may be constructed by electrochemically depositing polypyrrole-para-toluenesulfonate onto a PVDF substrate to create a membrane that selectively transports cations when a pulsed, square wave potential is applied to the membrane (see e.g., Price et al., Synthetic Metals 102: 1338-1341, 1999 which is incorporated herein by reference). Electroactive membranes with pores of preselected sizes may be created with an etching process using ion beam technology (see e.g., U.S. Pat. No. 7,632,406 issued to Wilson et al. on Dec. 15, 2009 which is incorporated herein by reference). Membranes comprised of electroactive polymers can act as valves with pores approximately 0.1-5.0 μm in diameter that open or close depending on the oxidation state of the polymers (see e.g., U.S. Patent Pub. No. 2006/0138371 by Gamier published on Jun. 29, 2006 which is incorporated herein by reference).
An absorbent polymer, e.g., hydrogel, is attached as a circular strip adjacent to the valve outlets on each reservoir port. For example the hydrogel may be composed of a polyvinyl alcohol (PVA)/polyethylene-co-vinyl alcohol (EVAL) copolymer combined with polyvinyl alcohol (PVA), and cast in an aluminum mold to create a planar, circular absorbent hydrogel surrounding the nipple. The hydrogel strip absorbs breast milk supplements from the reservoirs and presents them adjacent to the nipple for a breast feeding infant. Methods and materials for casting hydrogels are described (see e.g., U.S. Pat. No. 7,731,988 issued to Thomas et al. on Jun. 8, 2010 which is incorporated herein by reference).
The breast patch contains analyte sensors that monitor the levels of saliva analytes in the infant's saliva and/or breast milk analytes in the lactating female's breast milk in order to provide feedback to the control unit of the breast patch to control the delivery of breast milk supplements based on a breast milk supplement regimen personalized for the infant and mother. Analyte sensors are attached to the breast patch substrate, polyurethane layer, proximal to the nipple to allow sensing of nutrients, metabolites and biologicals in infant saliva and in breast milk. The levels of vitamins in infant saliva and breast milk are detected and reported to the control unit of the breast patch. For example, an analyte sensor to detect vitamin D may be used to monitor an infant's saliva and provide feedback to the control unit on the breast patch.
A biosensor based on a single-walled carbon nanotube (SWNT) with an aptamer recognition element for 25-hydroxy vitamin D (25-OH-D) is attached to the breast patch at a positioned adapted for placement in proximity to the nipple to sample saliva from the breast feeding infant. Methods and materials to construct SWNT biosensors with selected aptamers are described (see e.g., So et al., J. Am. Chem. Soc. 127, 11906-11907 and U.S. Pat. No. 5,475,096 issued to Gold et al. on Dec. 12, 1995 which are incorporated herein by reference).
The recommended serum level for 25-OH-D in adults is approximately ≥50 nmoles/L, and similar minimum levels are likely to be recommended for infant sera and infant saliva (see e.g., Wagner et al., Pediatrics 122, 1142-1152, 2008 and Fairney and Saphier, British Journal of Nutrition 57, 13-25, 1987 which are both incorporated herein by reference). Biosensor data on saliva 25-OH-D levels are received and processed by microcircuitry on the patch, and if 25-OH-D levels are insufficient (e.g., below 50 nmoles/L) then vitamin D3 supplement is delivered from the supplement reservoir. For example, a supplement of vitamin D3 as an oral preparation is available from Biotics Research Laboratory, Rosenberg, Tex. A supplement reservoir may contain 0.5 mL of vitamin D3 at a concentration of approximately 4000 IU/mL which is delivered at a rate of approximately 0.100 mL (400 IU)/day. Feedback from the 25-OH-D biosensor may indicate more or less vitamin D3 is required to keep the infant's saliva level at ≥50 nmoles/L. The breast patch microcircuitry and processors may be programmed to adjust the regimen to maintain a predetermined level of salivary 25-OH-D (e.g., ≥50 nmoles/L), or to deliver a daily dose of vitamin D according to a preset regimen recommended by health authorities (see e.g., Wagner et al., Ibid.). Input and modification of breast milk supplement regimen in the breast patch is mediated by radio frequency identification (RFID) tags which receive information from a remote computer or mobile device (i.e., cell phone, tablet, etc.).
The breast patch incorporates a RFID tag that includes antennas and circuitry to receive and transmit radio frequency signals to communicate with external computers and or mobile devices. The RFID tag is fabricated on a microchip that is attached to the upper polyurethane layer of the breast patch. For example the RFID device may be constructed by printing conductive ink (e.g., polymer with flecks of silver) to create circuitry. Conductive ink is used to print RFID antennas and to connect electronic components on the device. An integrated circuit defining the RFID circuitry for the device is printed on the substrate with conductive epoxy in connection with the conductive ink. The antenna may be a dipole antenna with a capacitor built in to store some of the electrical energy harvested from incident radio waves. The device may have a transmit circuit and a receive circuit to control radio wave communications through the antenna, a power harvester circuit to provide power to the device and a control circuit. Encapsulating epoxy material is used to cover the integrated circuit, the conductive ink and conductive epoxy. Methods and materials to construct RFID tags connected to sensors are described (see e.g., U.S. Pat. No. 7,479,886 issued to Burr on Jan. 20, 2009; U.S. Pat. No. 6,693,513 issue to Tuttle on Feb. 17, 2004 and U.S. Pat. No. 7,411,505 issued to Smith et al. on Aug. 12, 2008 which are incorporated herein by reference). The RFID device with an antenna for transmitting signals to a RFID reader may be constructed with circuitry to send an identification signal, and to transmit an alert when a delivery event has occurred or a supplement reservoir is nearly empty as indicated by the conductivity sensor (see e.g., Sample et al., IEEE Trans. Instr. Meas. 57: 2608-2615, 2008 which is incorporated herein by reference).
Prophetic Example 2: Smart Breast Patch to Deliver Supplements and Flavorings
An embodiment of a breast milk supplement delivery device including supplement reservoirs, tubing, ports, controllable valves and a pump to deliver breast milk supplements and flavorings to a breastfeeding infant is described. In this non-limiting example, the breast milk supplement delivery device takes the form of a flexible patch adapted for placement on a breast region of a lactating female. The breast patch includes microcircuitry, microprocessors, data storage components, and wireless transmission and receiving elements and a battery power source. Controlled delivery of breast milk supplements and flavorings is executed according to programmed regimens, and recorded and transmitted remotely by the breast patch. The breast patch is designed to adhere to the breast and position a delivery/sampling tube near to the nipple for supplement feeding or saliva or breast milk sample acquisition.
An adherent breast patch is constructed with a flexible, adherent lower layer and a polyurethane upper layer that includes sites for: reservoirs, a peristaltic pump, tubing, microcircuitry and a power source. A skin-adhesive first layer of the breast patch is cast using an acrylate copolymer dissolved in a volatile organic solvent which is subsequently evaporated to leave a planar, pressure sensitive adhesive patch. For example, an acrylate copolymer adhesive, dissolved in ethyl acetate may be cast as a rectangular patch approximately 5.0 cm×2.5 cm that adheres to skin on the breast (see FIG. 2B ). The adhesive layer is cast with indentations to receive supplement reservoirs, controllable valves, tubing and microcircuitry including a battery. A second layer, or housing, of polymer, e.g., polyurethane, is cast in a rectangular shape to overlay the adhesive first layer with corresponding aligned indentations to hold the supplement reservoirs and other components in place. (See e.g., U.S. Patent Application No. 2003/0152612 by Pugliese et al. published on Aug. 14, 2003 which is incorporated herein by reference.) The polyurethane housing can be removed for replacement of the supplement reservoirs or for repair/replacement of other components, e.g., the battery.
Disposable rectangular polyurethane supplement reservoirs, approximately 0.5 cm in width, 2.5 cm in length and 0.5 cm in depth are cast with a port at one end which accepts an electronic valve. Each disposable supplement reservoir docks in the adhesive first layer with its port connected to an electronic valve which connects to an intake manifold and lastly a micropump. Each supplement reservoir is equipped with a conductivity meter to monitor the level of supplement in the reservoir. A thin film conductivity sensor approximately 1.5 cm in length is available from Innovative Sensor Technology USA, Las Vegas, Nev. (see the Info Sheet: Conductivity Sensor LFS155).
A solenoid operated pinch valve is connected in line with each supplement reservoir to control the flow of supplements and/or flavorings from the supplement reservoirs. Compact pinch valves which employ approximately ⅛ inch inside diameter tubing are available from ASCO, Florham, N.J. (see e.g., Compact 2-Way Pinch Valve Info Sheet from ASCO which is incorporated herein by reference). A micropump is connected to the intake manifold and a delivery tube extends from the micropump to the nipple region. For example an electromagnetic micropump with a maximum flow rate of 70 μL/min is described (see e.g., Nisar et al., Sensors and Actuators B 130: 917-942, 2008 which is incorporated herein by reference). A lithium battery, incorporated in the patch provides power to drive the solenoid actuated pinch valves and the electromagnetic micropump.
Disposable supplement reservoirs are preloaded with flavorings to condition the breast feeding infant's taste preferences and ultimately the child's diet and nutrition. Flavors experienced during infancy influence taste preferences later in life (see e.g., Beauchamp and Mennella, Digestion 83 (suppl. 1): 1-6, 2011 and Ventura and Worobey, Current Biology 23: R401-R408, 2013 which are incorporated herein by reference). For example, the supplement reservoirs may be preloaded with flavorings from vegetables such as dark leafy greens (e.g., broccoli, spinach, and kale), carrots, peas, squash, cauliflower and peppers.
The supplement reservoirs may also contain nutrients and vitamins to supplement breast milk; for example, vitamin A, iron, vitamin C, folate, zinc, calcium, and vitamin D may be present alone or in combination in the supplement reservoirs. Recommended daily intake for nutrients and vitamins in infants are known (see e.g., USDA website, “Interactive DRI for Healthcare Professionals” online at http://fnic.nal.usda.gov/fnic/interactiveDRI/dri_results.php which is incorporated herein by reference). For example, a 3 month old infant weighing approximately 9 pounds has daily recommended intake (DRI) values: Vitamin A=400 mcg; Vitamin C=40 mg; iron=270 mcg; folate=65 mcg; zinc=2 mg; calcium=200 mg; Vitamin D=10 mcg. Dosing of nutrients and vitamins may be adjusted (i.e. decreased) to account for breast milk nutrients consumed by the infant.
The breast patch has a control unit with a data storage component to retain and execute a preset breast milk supplement regimen of flavorings, nutrients and vitamins to condition and supplement the infant's tastes and diet respectively. Microcircuitry, microprocessors and data storage components control the pinch valves and the pump to deliver selected flavorings and nutrients to the nipple when the child is breast feeding. The breast patch has a RFID transceiver that communicates with a remote computer or mobile device to receive data, e.g., a nutrient regimen, and report data, e.g., nutrient delivery, reservoir depletion, etc. Also a user interface is incorporated in the polyurethane housing to allow data input and control of the device. A projected capacitive touch controller is inserted in the surface of the polyurethane housing of the breast patch to allow gesture and tap control of device function. A projected capacitive touch controller is available from Microchip Technology, Inc., Chandler, Ariz. (see e.g., User Interface-Touchscreen Datasheet which is incorporated herein by reference). The delivery regimen, i.e., dose and schedule, may be adjusted by the control unit in response to analyte sensors on the device.
Analyte sensors are attached to the breast patch on an extension of the polyurethane substrate near to the nipple to sample infant saliva, and breast milk during infant feeding. For example, aptamer-based field effect transistor sensors capable of detecting small molecules, proteins and virus are sensitive and specific. Sensors with single walled carbon nanotubes (SWNT) with selected aptamers coupled to their surface to recognize and detect nutrients (e.g., folate, vitamin D) and biologicals (e.g., IgA antibodies) are attached to the breast patch and connected to the control unit. Methods and materials to select aptamers and construct SWNT sensors are described (see e.g., U.S. Pat. No. 5,475,096 issued to Gold et al. on Dec. 12, 1995 and Lee et al., Analytical Bioanalytical Chemistry 390: 1023-1032, 2008 which are incorporated herein by reference). Signals from the analyte sensors on nutrient levels or biologicals are processed by the control unit and the schedule and dose of nutrient delivery may be adjusted, continued as preset, or stopped. Signals (i.e., data) on analyte levels, delivery regimens and reservoir nutrient levels may also be transmitted to a remote computer or mobile device via a RFID transceiver on the breast patch device.
The breast patch incorporates an RFID transmission unit as described in Prophetic Example 1. The RFID transmission unit includes antennas and circuitry to receive and transmit radio frequency signals to communicate with external computers and or mobile devices.
Prophetic Example 3: Pacifier with Controlled Delivery of Breast Milk Supplements
An embodiment of a breast milk supplement delivery device is described. In this non-limiting example, the breast milk supplement delivery device takes the form a pacifier constructed to deliver breast milk supplements in a controlled fashion to an infant. The pacifier contains supplement reservoirs which release breast milk supplements under the direction of a control unit which includes microcircuitry, microprocessors, and memory. The control unit also contains wireless communication elements to receive breast milk supplement regimen information and to report on nutrient and flavoring delivery and consumption. Analyte sensors on the pacifier may detect nutrient supplements, flavorings, biologicals and metabolites in infant saliva. Signaling from analyte sensors is processed by the control unit which may respond by adjusting the breast milk supplement regimen. Nutrient delivery from the supplement reservoirs is controlled by electronic valves which are actuated by the control unit. A tube connects each supplement reservoir port with the nipple opening and sucking by the infant draws nutrient supplements through the pacifier nipple.
FIG. 41 illustrates non-limiting aspects of a pacifier adapted to deliver one or more breast milk supplements. Pacifier 4100 includes nipple component 4110 including an aperture 4115 , a guard component 4120 , a flow conduit 4130 at least partially disposed within nipple component 4110 and guard component 4120 , disposable supplement reservoirs 4140 , a controllable valve 4150 , and a control unit 4160 . The disposable supplement reservoirs 4140 are in fluid communication with the flow conduit 4130 through the controllable valve 4150 . In this non-limiting example, components of the disposable supplement reservoirs 4140 are attached to guard component 4120 , with flow conduit 4130 passing through the guard component 4120 and connecting the disposable supplement reservoirs 4140 with aperture 4115 of the nipple component 4110 .
Silicon rubber is cast in a mold to create a nipple component with an aperture (e.g., an opening), a flow conduit (e.g., a tube) connecting the nipple component to the guard component, and docking sites for the disposable supplement reservoirs, the controllable valves, and the control unit. Methods and materials to construct a device with a nipple and conduits are described (see e.g., U.S. Patent Appl. No. 2008/0167579 by Ezra et al. published on Jul. 10, 2008 which is incorporated herein by reference). Disposable supplement reservoirs may be molded from polyurethane with a complementary docking site and a port that accepts an electronic valve. For example, custom-molded polyurethane elastomer devices are available from Precision Engineering Products, East Providence, R.I. (see e.g., info sheet: PEP microPEP Drug Delivery Device Solutions available online at: http://www.pepmicropep.com/markets/medical-surgical/drug-delivery-device-solutions which is incorporated herein by reference). Disposable supplement reservoirs containing approximately 0.50 mL of a breast milk supplement are connected to electronic valves via their delivery ports and the combination, disposable supplement reservoir plus controllable valve, is attached to the pacifier at the reservoir docking site with the exit port of the valve connected to flow conduit near the guard component. Miniature electronic valves to control the flow of supplements from the disposable supplement reservoirs are available, for example, an 8 mm diaphragm isolation valve is available from ASCO, Florham, N.J. (See e.g., ASCO info sheet: 8 mm Diaphragm Isolation which is incorporated herein by reference.) Supplement delivery is initiated by opening an electronic valve at a reservoir port thus allowing an infant to suck the supplement through the valve and delivery tube which opens into the nipple opening and finally the infant's mouth. The reservoir also has an internal conductivity sensor to monitor the level of nutrient or flavoring remaining in the reservoir. Each reservoir is equipped with a conductivity sensor to monitor the level of supplement in the reservoir. A thin film conductivity sensor approximately 1.5 cm in length is available from Innovative Sensor Technology USA, Las Vegas, Nev. (see the Info Sheet: Conductivity Sensor LFS155). Supplement levels are reported to the control unit on the pacifier and they may be relayed to a remote computer or mobile device. For example, if a supplement reservoir is nearly empty, as reflected in its conductivity readings, then a parent or caregiver may be alerted to provide a new supplement reservoir filled with one or more breast milk supplements, or alternatively, a duplicate supplement reservoir on the pacifier may be activated automatically.
The pacifier is constructed with a control unit including microcircuitry, microprocessors, data storage component, and RFID transceivers that control the delivery of breast milk supplements to the infant and report delivery events to remote computers and mobile devices. A data storage component retains protocols for supplement delivery, i.e., one or more breast milk supplement regimens that include dose and schedule for specific nutrients. For example, a regimen for Vitamin D3 is executed by actuation circuitry that actuates (opens) the controllable valve for a vitamin D3 reservoir. Infant sucking on the pacifier results in vitamin D3 consumption and conductivity readings from the reservoir will reflect the amount remaining. The consumption of vitamin D3 is processed by the control unit to inform actuation of the controllable valve until a regimen is completed, e.g., 400 IU/day, for 5 days. Also the control unit reports on vitamin D3 consumption and reservoir depletion to remote computers and mobile devices.
The pacifier incorporates sensors to provide feedback control of supplement delivery. An infant presence detector, e.g., a pressure transducer, is located in the flow conduit of the pacifier that detects negative pressure when the infant is sucking on the pacifier. For example, a pressure sensor that detects and quantifies negative pressure from infant sucking is described (see e.g., Prieto et al., J. Reproduction and Fertility 108, 69-74, 1996 which is incorporated herein by reference). When sucking is detected, the control unit initiates supplement delivery by actuating the controllable valves as required. Analyte sensors located on the nipple component of the pacifier detect nutrients, metabolites, biologicals and flavorings in the infant's saliva, and analyte data is processed by the control unit to adjust the breast milk supplement regimen. For example, aptamer-based field effect transistor sensors capable of detecting small molecules, proteins and virus are sensitive and specific. Sensors with single walled carbon nanotubes (SWNT) with selected aptamers coupled to their surface to recognize and detect nutrients (e.g., folate, vitamin D) and biologicals (e.g., IgA antibodies) are attached to the nipple component and connected to the control unit. Methods and materials to select aptamers and construct SWNT sensors are described (see e.g., U.S. Pat. No. 5,475,096 issued to Gold et al. on Dec. 12, 1995 and Lee et al., Analytical Bioanalytical Chemistry 390: 1023-1032, 2008 which are incorporated herein by reference).
RFID transceivers on the pacifier receive data on supplement regimens and transmit data on supplement delivery and reservoir status. A RFID transceiver that includes antennas and circuitry to receive and transmit radio frequency signals communicates with external computers and or mobile devices as described in Prophetic Example 1.
The state of the art has progressed to the point where there is little distinction left between hardware, software, and/or firmware implementations of aspects of systems; the use of hardware, software, and/or firmware is generally (but not always, in that in certain contexts the choice between hardware and software can become significant) a design choice representing cost vs. efficiency tradeoffs. There are various vehicles by which processes and/or systems and/or other technologies described herein can be effected (e.g., hardware, software, and/or firmware), and that the preferred vehicle will vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer may opt for a mainly hardware and/or firmware vehicle; alternatively, if flexibility is paramount, the implementer may opt for a mainly software implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software, and/or firmware. Hence, there are several possible vehicles by which the processes and/or devices and/or other technologies described herein can be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle will be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which may vary. Those skilled in the art will recognize that optical aspects of implementations will typically employ optically-oriented hardware, software, and or firmware.
In some implementations described herein, logic and similar implementations can include software or other control structures. Electronic circuitry, for example, may have one or more paths of electrical current constructed and arranged to implement various functions as described herein. In some implementations, one or more media can be configured to bear a device-detectable implementation when such media hold or transmit a device detectable instructions operable to perform as described herein. In some variants, for example, implementations can include an update or modification of existing software or firmware, or of gate arrays or programmable hardware, such as by performing a reception of or a transmission of one or more instructions in relation to one or more operations described herein. Alternatively or additionally, in some variants, an implementation can include special-purpose hardware, software, firmware components, and/or general-purpose components executing or otherwise invoking special-purpose components. Specifications or other implementations can be transmitted by one or more instances of tangible transmission media as described herein, optionally by packet transmission or otherwise by passing through distributed media at various times.
Alternatively or additionally, implementations may include executing a special-purpose instruction sequence or otherwise invoking circuitry for enabling, triggering, coordinating, requesting, or otherwise causing one or more occurrences of any functional operations described above. In some variants, operational or other logical descriptions herein may be expressed directly as source code and compiled or otherwise invoked as an executable instruction sequence. In some contexts, for example, C++ or other code sequences can be compiled directly or otherwise implemented in high-level descriptor languages (e.g., a logic-synthesizable language, a hardware description language, a hardware design simulation, and/or other such similar mode(s) of expression). Alternatively or additionally, some or all of the logical expression may be manifested as a Verilog-type hardware description or other circuitry model before physical implementation in hardware, especially for basic operations or timing-critical applications. Those skilled in the art will recognize how to obtain, configure, and optimize suitable transmission or computational elements, material supplies, actuators, or other common structures in light of these teachings.

A data processing system generally includes one or more of a system unit housing, a video display device, memory such as volatile or non-volatile memory, processors such as microprocessors or digital signal processors, computational entities such as operating systems, drivers, graphical user interfaces, and applications programs, one or more interaction devices (e.g., a touch pad, a touch screen, an antenna, etc.), and/or control systems including feedback loops and control motors. A data processing system can be implemented utilizing suitable commercially available components, such as those typically found in data computing/communication and/or network computing/communication systems.
In certain cases, use of a system or method may occur in a territory even if components are located outside the territory. For example, in a distributed computing context, use of a distributed computing system may occur in a territory even though parts of the system may be located outside of the territory (e.g., relay, server, processor, signal-bearing medium, transmitting computer, receiving computer, etc. located outside the territory). A sale of a system or method may likewise occur in a territory even if components of the system or method are located and/or used outside the territory.
Further, implementation of at least part of a system for performing a method in one territory does not preclude use of the system in another territory.
One skilled in the art will recognize that the herein described components (e.g., operations), devices, objects, and the discussion accompanying them are used as examples for the sake of conceptual clarity and that various configuration modifications are contemplated. Consequently, as used herein, the specific exemplars set forth and the accompanying discussion are intended to be representative of their more general classes. In general, use of any specific exemplar is intended to be representative of its class, and the non-inclusion of specific components (e.g., operations), devices, and objects should not be taken limiting.
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations are not expressly set forth herein for sake of clarity.
The herein described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely exemplary, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “operably coupled to” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected,” or “operably coupled,” to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “operably couplable,” to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components, and/or wirelessly interactable, and/or wirelessly interacting components, and/or logically interacting, and/or logically interactable components.
In some instances, one or more components can be referred to herein as “configured to,” “configured by,” “configurable to,” “operable/operative to,” “adapted/adaptable,” “able to,” “conformable/conformed to,” etc. Those skilled in the art will recognize that such terms (e.g. “configured to”) can generally encompass active-state components and/or inactive-state components and/or standby-state components, unless context requires otherwise.
While particular aspects of the present subject matter described herein have been shown and described, it will be apparent to those skilled in the art that, based upon the teachings herein, changes and modifications can be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of the subject matter described herein.
It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to claims containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that typically a disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms unless context dictates otherwise. For example, the phrase “A or B” will be typically understood to include the possibilities of “A” or “B” or “A and B.”
