Apparatus, systems and methods disclosed herein relate to contact lenses performing temperature compensation for sensors on the contact lenses and/or that facilitate body and/or ambient temperature sensing and sensor fusion or calibration. In some aspects, the contact lens includes: a substrate; and a circuit. The circuit can include: one or more sensors disposed on or within the substrate and that sense a feature associated with a wearer of the contact lens; and a compensation circuit disposed on or within the substrate and coupled to the one or more sensors and that outputs information to the one or more sensors to adjust an output of the one or more sensors.

One or more aspects of the apparatus, systems and/or methods described herein can advantageously facilitate contact lens temperature compensation and/or temperature sensing. Accordingly, the aspects can facilitate accuracy of contact lens sensor output while minimizing power consumption and complexity of the contact lens circuitry. In some aspects, on-chip compensation can facilitate analog modulation for sensor reading. In some aspects, the apparatus, systems and/or methods can be employed for sensor fusion and/or calibration of the temperature sensor.

FIG. 1is an illustration of a block diagram of an exemplary non-limiting system that facilitates temperature compensation for a contact lens sensor in accordance with aspects described herein. The system100can be described in greater detail with reference toFIGS. 1,2and3.FIG. 2is an illustration of an exemplary non-limiting graph of sensor output versus temperature for a contact lens sensor in accordance with aspects described herein.FIG. 3is an illustration of an exemplary non-limiting graph facilitating temperature compensation for a contact lens sensor in accordance with aspects described herein.

System100can be disposed on or within a contact lens in various aspects. In some aspects, system100can include a circuit101having a sensor102and a compensation circuit104. In various aspects, the sensor102and/or compensation circuit104can be electrically and/or communicatively coupled to one another to perform one or more functions of the system100.

In some aspects, the sensor102can sense one or more biological features associated with the wearer of the contact lens. The sensor102can output a current indicative of a sensed value for the biological feature in various aspects. In some aspects, the sensor102can output a value indicative of a level of the sensed biological feature.

In some aspects, the sensed value can vary depending on the temperature of the sensor. As seen inFIG. 2, ideally, the sensor output is independent of the temperature of the sensor. However, in practice, in some aspects, the sensor output can vary in proportion to the temperature of the sensor. Further, while the graph ofFIG. 2shows a linear relationship between current and temperature, in various aspects, the relationship is exponential. For example, a glucose level of a wearer of the contact lens might be constant but the output current of the sensor could increase when the sensor measuring the glucose experiences a temperature increase. Accordingly, the sensor102could appear to indicate a sensed increase in glucose level that is actually false.

Accordingly, for a same sensed biological feature value, the actual sensor output can be higher or lower than the true value based on the temperature of the sensor. Because the sensor output can depend on the temperature of the sensor102, the temperature of the sensor102can be employed to calibrate/adjust the output/reading of the sensor102.

The sensor102output/reading can be a current level in some aspects. In some aspects, the sensor102output/reading can be a value associated with the biological feature sensed.

The compensation circuit104can compensate for the inaccuracy in sensor output based on temperature.

Turning back toFIG. 1, the biological features sensed by the sensor102can include, but are not limited to, a glucose level, alcohol level, histamine level, urea level, lactate level and/or cholesterol level of the wearer of the contact lens. In some aspects, the biological feature can include, but is not limited to, a sodium ion (Na+) level, potassium ion (K+) level, calcium ion (Ca2+) level or magnesium ion (Mg2+) level of the wearer of the contact lens.

The compensation circuit104can include a communication component106, a temperature component108, an evaluation component110, an adjustment component112, a power component114, a memory116and/or a microprocessor118.

In various aspects, the communication component106can transmit and/or receive information indicative of the temperature of the sensor102, indicative of the information sensed by the sensor (e.g., the biological feature value) and/or indicative of a current output from the sensor102. In some aspects, the communication component106can receive information associated with adjusting the output of the sensor102. The information can be for correcting the erroneous sensor output that is due to temperature of the sensor102.

The temperature component108can sense the temperature of the sensor102. In various aspects, the temperature component108can adjust the output indicative of the sensed feature based on the information indicative of the temperature of the sensor.

The evaluation component110can evaluate the temperature of the sensor102and generate information for temperature compensation. For example, in some aspects, the evaluation component110can determine an adjustment value that, when subtracted from the current output from the sensor (or, in some aspects, when subtracted from the sensed biological feature value) compensates for the impact the temperature of the sensor102has on the current output or feature value. The evaluation component110can determine the adjustment value based on the relationship between current and temperature as shown inFIG. 3. While the relationship inFIG. 3is shown as linear, the graph is merely exemplary, and can be any line having a slope and/or orientation that is generally equal and opposite to that of the actual relationship of the sensor current versus temperature, so as to remove the effects of temperature on the current.

For example, in some aspects, the evaluation component110can characterize the output of the sensor102as a function of temperature. Specifically, the evaluation component110can determine a temperature coefficient that should be associated with the sensor102. The temperature coefficient can be indicative of a change in current output from the sensor102as a function of temperature.

The adjustment component112can perform the compensation to the sensor output and generate the adjusted sensor output. For example, employing a graph such as that shown inFIG. 3(or an algorithm associated with such a graph), in some aspects, the adjustment component112can subtract the adjustment value from the output of the sensor (e.g., either the current output and/or the sensed biological feature value) to determine the corrected sensor output. In some aspects, the adjustment component112can include information indicative of a slope of sensor output current versus temperature. The adjustment component112can also include an adjustment slope having an equal and opposite slope to the sensor output current versus temperature slope. As such, when the sensor increases current output, the adjustment component112can subtract a same amount of current to compensate and keep the sensor reading correct.

As another example, in some aspects, the adjustment component112can employ the temperature coefficient determined by the evaluation component110to determine the proper current for the sensor102. For example, the adjustment component112can multiply the current output from the sensor102by the temperature coefficient to generate the corrected current value. The corrected current value can be translated to the corrected sensed biological feature value.

In some aspects, the temperature component108can receive the adjustment information from a reader external to the contact lens. For example, the sensor output and/or the temperature sensed can be transmitted to the reader. In various aspects, the reader can include any number of components that can transmit and/or receive information wirelessly including, but not limited to, an RF reader, mobile phone, laptop, personal computer (PC), tablet, personal digital assistant (PDA), head-mounted device or the like. In some aspects, the reader can transmit to the temperature component108information for adjustment of the sensed biological feature value. The adjusted biological feature value can then be output from a component of the contact lens. In some aspects, the reader can adjust the sensor output based on the temperature of the sensor and output the adjusted sensor biological feature value.

The power component114can generate and/or output power to one or more components of the circuit101. The power component114can provide power to one or more components of the circuit101through storing/converting solar energy and/or energy received from radio frequency waves in various aspects.

By way of example, but not limitation, the temperature sensor can be calibrated based on the additional sensed temperature reported by a weather service reporting on temperature in an area proximate to the area in which the wearer of the contact lens is located. The temperature sensed on the contact lens can be compared to the temperature reported by the weather service and the temperature component on the contact lens that sensed the temperature can be calibrated based at least in part on the temperature reported by the weather service.

Exemplary Networked and Distributed Environments

One of ordinary skill in the art can appreciate that the various aspects described in this disclosure can be implemented in connection with any computer or other client or server device, which can be deployed as part of a computer network or in a distributed computing environment, and can be connected to any kind of data store. In this regard, the various aspects described in this disclosure can be implemented in association with any computer system or environment having any number of memory or storage units, and any number of applications and processes occurring across any number of storage units. This includes, but is not limited to, an environment with server computers and client computers deployed in a network environment or a distributed computing environment, having remote or local storage.

Distributed computing provides sharing of computer resources and services by communicative exchange among computing devices and systems. These resources and services include the exchange of information, cache storage and disk storage for objects, such as files. These resources and services can also include the sharing of processing power across multiple processing units for load balancing, expansion of resources, specialization of processing, and the like. Distributed computing takes advantage of network connectivity, allowing clients to leverage their collective power to benefit the entire enterprise. In this regard, a variety of devices may have applications, objects or resources that may participate in the various aspects of this disclosure.

FIG. 12provides a schematic diagram of an exemplary networked or distributed computing environment with which one or more aspects described in this disclosure can be associated. The distributed computing environment includes computing objects1210,1212, etc. and computing objects or devices1220,1222,1224,1226,1228, etc., which can include programs, methods, data stores, programmable logic, etc., as represented by applications1230,1232,1234,1236,1238. It can be appreciated that computing objects1210,1212, etc. and computing objects or devices1220,1222,1224,1226,1228, etc. can include different devices, such as personal digital assistants (PDAs), audio/video devices, mobile phones, MPEG-1 Audio Layer 3 (MP3) players, personal computers, laptops, tablets, etc.

Each computing object1210,1212, etc. and computing objects or devices1220,1222,1224,1226,1228, etc. can communicate with one or more other computing objects1210,1212, etc. and computing objects or devices1220,1222,1224,1226,1228, etc. by way of the communications network1240, either directly or indirectly. Even though illustrated as a single element inFIG. 12, network1240can include other computing objects and computing devices that provide services to the system ofFIG. 12, and/or can represent multiple interconnected networks, which are not shown. Each computing object1210,1212, etc. or computing objects or devices1220,1222,1224,1226,1228, etc. can also contain an application, such as applications1230,1232,1234,1236,1238, that might make use of an application programming interface (API), or other object, software, firmware and/or hardware, suitable for communication with or aspect of the various aspects of the subject disclosure.

Thus, a host of network topologies and network infrastructures, such as client/server, peer-to-peer, or hybrid architectures, can be utilized. The client can be a member of a class or group that uses the services of another class or group. A client can be a computer process, e.g., roughly a set of instructions or tasks, that requests a service provided by another program or process. A client can utilize the requested service without having to know all working details about the other program or the service itself.

In a client/server architecture, particularly a networked system, a client can be a computer that accesses shared network resources provided by another computer, e.g., a server. In the illustration ofFIG. 12, as a non-limiting example, computing objects or devices1220,1222,1224,1226,1228, etc. can be thought of as clients and computing objects1210,1212, etc. can be thought of as servers where computing objects1210,1212, etc. provide data services, such as receiving data from client computing objects or devices1220,1222,1224,1226,1228, etc., storing of data, processing of data, transmitting data to client computing objects or devices1220,1222,1224,1226,1228, etc., although any computer can be considered a client, a server, or both, depending on the circumstances. Any of these computing devices can process data, or request transaction services or tasks that can implicate the techniques for systems as described in this disclosure for one or more aspects.

In a network environment in which the communications network/bus1240can be the Internet, for example, the computing objects1210,1212, etc. can be Web servers, file servers, media servers, etc. with which the client computing objects or devices1220,1222,1224,1226,1228, etc. communicate via any of a number of known protocols, such as the hypertext transfer protocol (HTTP). Objects1210,1212, etc. can also serve as client computing objects or devices1220,1222,1224,1226,1228, etc., as can be characteristic of a distributed computing environment.

Exemplary Computing Device

As mentioned, advantageously, the techniques described in this disclosure can be associated with any suitable device. It is to be understood, therefore, that handheld, portable and other computing devices and computing objects of all kinds are contemplated for use in connection with the various aspects, i.e., anywhere that a device may wish to read or write transactions from or to a data store. The data store can read and/or write information to or from a memory (e.g., memory116,514,606), contact lens (e.g., contact lens402,422,442) and/or reader (e.g., reader410,430,450). In various aspects, the data store can be or can include a memory (e.g., memory116,514,606). In some aspects, the data store can be or can include a contact lens (e.g., contact lens402,422,442) as the contact lens can read and/or write transactions to or from one component of the contact lens to another component of the contact lens. In some aspects, the data store can be or can include a reader (e.g., reader410,430,450).

Accordingly, the below remote computer described below inFIG. 13is but one example of a computing device. Additionally, a suitable server can include one or more aspects of the below computer or other server components.

FIG. 13thus illustrates an example of a suitable computing system environment1300in which one or aspects of the aspects described in this disclosure can be implemented or associated, although as made clear above, the computing system environment1300is only one example of a suitable computing environment and is not intended to suggest any limitation as to scope of use or functionality. Neither is the computing environment1300to be interpreted as having any dependency or requirement relating to any one or combination of components illustrated in the exemplary computing environment1300.

With reference toFIG. 13, an exemplary computing environment1300for implementing one or more aspects includes a computing device in the form of a computer1310is provided. Components of computer1310can include, but are not limited to, a processing unit1320, a system memory1330, and a system bus1322that couples various system components including the system memory to the processing unit1320.

A monitor or other type of display device can be also connected to the system bus1322via an interface, such as output interface1350. In addition to a monitor, computers can also include other peripheral output devices such as speakers and a printer, which can be connected through output interface1350.

The computer1310can operate in a networked or distributed environment using logical connections to one or more other remote computers, such as remote computer1380. The remote computer1380can be a personal computer, a server, a router, a network PC, a peer device or other common network node, or any other remote media consumption or transmission device, and can include any or all of the elements described above relative to the computer1310. The logical connections depicted inFIG. 13include a network1382, such local area network (LAN) or a wide area network (WAN), but can also include other networks/buses e.g., cellular networks.

Also, there are multiple ways to implement the same or similar functionality, e.g., an appropriate API, tool kit, driver code, operating system, control, standalone or downloadable software object, etc. which enables applications and services to take advantage of the techniques detailed herein. Thus, aspects herein are contemplated from the standpoint of an API (or other software object), as well as from a software or hardware object that implements one or more aspects described in this disclosure. Thus, various aspects described in this disclosure can have aspects that are wholly in hardware, partly in hardware and partly in software, as well as in software.

Computing devices typically include a variety of media, which can include computer-readable storage media and/or communications media, in which these two terms are used herein differently from one another as follows. Computer-readable storage media can be any available storage media that can be accessed by the computer, can be typically of a non-transitory nature, and can include both volatile and nonvolatile media, removable and non-removable media. By way of example, and not limitation, computer-readable storage media can be implemented in connection with any method or technology for storage of information such as computer-readable instructions, program components, structured data, or unstructured data. Computer-readable storage media can include, but are not limited to, RAM, ROM, electrically erasable programmable read only memory (EEPROM), flash memory or other memory technology or other tangible and/or non-transitory media that can be used to store desired information. Computer-readable storage media can be accessed by one or more local or remote computing devices, e.g., via access requests, queries or other data retrieval protocols, for a variety of operations with respect to the information stored by the medium. In various aspects, the computer-readable storage media can be, or be included within, the memory, contact lens (or components thereof) or reader described herein.

It is to be understood that the aspects described in this disclosure can be implemented in hardware, software, firmware, middleware, microcode, or any combination thereof. For a hardware aspect, the processing units can be implemented within one or more application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), processors, controllers, micro-controllers, microprocessors and/or other electronic units designed to perform the functions described in this disclosure, or a combination thereof.

For a software aspect, the techniques described in this disclosure can be implemented with components or components (e.g., procedures, functions, and so on) that perform the functions described in this disclosure. The software codes can be stored in memory units and executed by processors. A memory unit can be implemented within the processor or external to the processor, in which case it can be communicatively coupled to the processor via various structures.

What has been described above includes examples of one or more aspects. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the aforementioned aspects, but one of ordinary skill in the art can recognize that many further combinations and permutations of various aspects are possible. Accordingly, the described aspects are intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims. Moreover, use of the term “an aspect” or “one aspect” throughout is not intended to mean the same aspect unless specifically described as such. Further, use of the term “plurality” can mean two or more.

The aforementioned systems have been described with respect to interaction between several components. It can be appreciated that such systems and components can include those components or specified sub-components, some of the specified components or sub-components, and/or additional components, and according to various permutations and combinations of the foregoing. Sub-components can also be implemented as components communicatively coupled to other components rather than included within parent components (hierarchical). Additionally, it is to be noted that one or more components can be combined into a single component providing aggregate functionality or divided into several separate sub-components, and that any one or more middle layers, such as a management layer, can be provided to communicatively couple to such sub-components in order to provide integrated functionality. Any components described in this disclosure can also interact with one or more other components not specifically described in this disclosure but generally known by those of skill in the art.

In addition to the various aspects described in this disclosure, it is to be understood that other similar aspects can be used or modifications and additions can be made to the described aspect(s) for performing the same or equivalent function of the corresponding aspect(s) without deviating there from. Still further, multiple processing chips or multiple devices can share the performance of one or more functions described in this disclosure, and similarly, storage can be provided across a plurality of devices. The invention is not to be limited to any single aspect, but rather can be construed in breadth, spirit and scope in accordance with the appended claims.
