The use of mobile communication devices (or mobile devices), such as personal data assistants (PDAs), cell phones (including smart phones or mobile phones), and tablet computers, is ubiquitous. These devices must be supplied with electricity to function and typically include rechargeable batteries to enable portability. The rechargeable batteries are typically recharged through the use of battery chargers which plug into a port on the mobile device and to an electrical outlet to facilitate the transfer of electrical power. Consequently, when a mobile device is charging, the device essentially becomes tethered to the wall and its portability aspect is lost for the duration of time the battery is recharged.

I. Example Wireless Power Delivery System Overview/Architecture
As shown in the example of
Each charger 101 (also referred to herein as a “transmitter”, “array of antennas” or “antenna array system”) can include multiple antennas 104, e.g., an antenna array including hundreds or thousands of antennas, which are capable of delivering wireless power to wireless devices 102. In some embodiments, the antennas are adaptively-phased radio frequency antennas. The charger 101 is capable of determining the appropriate phases to deliver a coherent power transmission signal to the power receiver clients 103. The array is configured to emit a signal (e.g., continuous wave or pulsed power transmission signal) from multiple antennas at a specific phase relative to each other. It is appreciated that use of the term “array” does not necessarily limit the antenna array to any specific array structure. That is, the antenna array does not need to be structured in a specific “array” form or geometry. Furthermore, as used herein he term “array” or “array system” may be used include related and peripheral circuitry for signal generation, reception and transmission, such as radios, digital logic and modems. In some embodiments, the charger 101 can have an embedded Wi-Fi hub.
The wireless devices 102 can include one or more receive power clients 103. As illustrated in the example of
Each power receiver client 103.1-103.n includes one or more antennas (not shown) for receiving signals from the chargers 101. Likewise, each charger 101.a-101.n includes an antenna array having one or more antennas and/or sets of antennas capable of emitting continuous wave signals at specific phases relative to each other. As discussed above, each array is capable of determining the appropriate phases for delivering coherent signals to the power receiver clients 102.1-102.n. For example, coherent signals can be determined by computing the complex conjugate of a received beacon signal at each antenna of the array such that the coherent signal is properly phased for the particular power receiver client that transmitted the beacon signal.
Although not illustrated, each component of the environment, e.g., wireless power receiver, charger, etc., can include control and synchronization mechanisms, e.g., a data communication synchronization module. The chargers 101.a-101.n can be connected to a power source such as, for example, a power outlet or source connecting the chargers to a standard or primary alternating current (AC) power supply in a building. Alternatively or additionally, one or more of the chargers 101.a-101.n can be powered by a battery or via other mechanisms.
In some embodiments, the power receiver clients 102.1-102.n and/or the chargers 101.a-101.n utilize reflective objects 106 such as, for example, walls or other RF reflective obstructions within range to transmit beacon signals and/or receive wireless power and/or data within the wireless power delivery environment. The reflective objects 106 can be utilized for multi-directional signal communication regardless of whether a blocking object is in the line of sight between the charger and the power receiver client.
As described herein, each wireless device 102.1-102.n can be any system and/or device, and/or any combination of devices/systems that can establish a connection with another device, a server and/or other systems within the example environment 100. In some embodiments, the wireless devices 102.1-102.n include displays or other output functionalities to present data to a user and/or input functionalities to receive data from the user. By way of example, a wireless device 102 can be, but is not limited to, a video game controller, a server desktop, a desktop computer, a computer cluster, a mobile computing device such as a notebook, a laptop computer, a handheld computer, a mobile phone, a smart phone, a PDA, a Blackberry device, a Treo, and/or an iPhone, etc. The wireless device 102 can also be any wearable device such as watches, necklaces, rings or even devices embedded on or within the customer. Other examples of a wireless device 102 include, but are not limited to, safety sensors (e.g., fire or carbon monoxide), electric toothbrushes, electronic door lock/handles, electric light switch controller, electric shavers, etc.
Although not illustrated in the example of
As shown, the charger 101 receives the beacon from the power receiver client 103 and decodes the encoded beacon signal using the transmission code provided to the client 103 to ensure that the client 103 is an authorized or selected client. The charger 101 also detects the phase (or direction) at which the beacon signal is received and, once the charger determines that the client is authorized, delivers wireless power and/or data to the power receiver client 103 based the phase (or direction) of the received beacon. In some embodiments, the charger 101 can determine the complex conjugate of the phase and use the complex conjugate to deliver and/or otherwise direct wireless power to the power receiver client 103 in the same direction (or phase) in which the beacon signal was received from the power receiver client 103.
In some embodiments, the charger 101 includes many antennas; one or more of which are used to deliver power to the power receiver client 103. The charger 101 can detect phases at which the beacon signals are received at each antenna. The large number of antennas may result in different coded beacon signals being received at each antenna of the charger 101. The charger may then determine the complex conjugate of the beacon signals received at each antenna. Using the complex conjugates, one or more antenna may emit a signal that takes into account the effects of the large number of antennas in the charger 101. In other words, the charger 101 emits a signal from one or more antennas in such a way as to create an aggregate signal from the one or more of the antennas that approximately recreates the waveform of the beacon in the opposite direction.
As discussed herein, wireless power can be delivered in power cycles defined by power schedule information. A more detailed example of the signaling required to commence wireless power delivery is described now with reference to
The control logic 310 is configured to provide control and intelligence to the array components. The control logic 310 may comprise one or more processors, FPGAs, memory units, etc., and direct and control the various data and power communications. The communication block 330 can direct data communications on a data carrier frequency, such as the base signal clock for clock synchronization. The data communications can be Bluetooth, Wi-Fi, ZigBee, etc. Likewise, the proxy 340 can communicate with clients via data communications as discussed herein. The data communications can be Bluetooth, Wi-Fi, ZigBee, etc.
In some embodiments, the control logic 310 can also facilitate and/or otherwise enable data aggregation for Internet of Things (IoT) devices. In some embodiments, wireless power clients can access, track and/or otherwise obtain IoT information about the device in which the wireless power receiver is embedded and provide that IoT information to the wireless charger 300 over a data connection. This IoT information can be provided to via an external data interface 315 to a central or cloud-based system (not shown) where the data can be aggregated, processed, etc. For example, the central system can process the data to identify various trends across geographies, chargers, environments, devices, etc. In some embodiments, the aggregated data and or the trend data can be used to improve operation of the devices via remote updates, etc. Alternatively or additionally, in some embodiments, the aggregated data can be provided to third party data consumers. In this manner, the wireless charger acts as a Gateway or Enabler for the IoTs. By way of example and not limitation, the IoT information can include capabilities of the device in which the wireless power receiver is embedded, usage information of the device, power levels of the device, information obtained by the device or the wireless power receiver itself, e.g., via sensors, etc.
The external power interface 320 is configured to receive external power and provide the power to various components. In some embodiments, the external power interface 320 may be configured to receive a standard external 24 Volt power supply. Alternative configurations are also possible.
An example of a system power cycle is now described. In this example, the master bus controller (MBC), which controls the charger array, first receives power from a power source and is activated. The MBC then activates the proxy antenna elements on the charger array and the proxy antenna elements enter a default “discovery” mode to identify available wireless receiver clients within range of the charger array. When a client is found, the antenna elements on the charger array power on, enumerate, and (optionally) calibrate.
Next, the MBC generates beacon transmission scheduling information and power transmission scheduling information during a scheduling process. The scheduling process includes selection of power receiver clients. For example, the MBC can select power receiver clients for power transmission and generate a Beacon Beat Schedule (BBS) cycle and a Power Schedule (PS) for the selected wireless power receiver clients. A graphical signaling representation of an example BBS and PS is shown and discussed in greater detail with reference to
In some embodiments, the MBC can also identify and/or otherwise select available clients that will have their status queried in the Client Query Table (CQT). Clients that are placed in the CQT are those on “standby”, e.g., not receiving a charge. The BBS and PS are calculated based on vital information about the clients such as, for example, battery status, current activity/usage, how much longer the client has until it runs out of power, priority in terms of usage, etc.
The Proxy AE broadcasts the BBS to all clients. As discussed herein, the BBS indicates when each client should send a beacon. Likewise the PS indicates when and to which clients the array should send power to. Each client starts broadcasting its beacon and receiving power from the array per the BBS and PS. The Proxy can concurrently query the Client Query Table to check the status of other available clients. A client can only exist in the BBS or the CQT (e.g., waitlist), but not in both. In some embodiments, a limited number of clients can be served on the BBS and PS (e.g., 32). Likewise, the CQT may also be limited to a number of clients (e.g., 32). Thus, for example, if more than 64 clients are within range of the charger, some of those clients would not be active in either the BBS or CQT. The information collected in the previous step continuously and/or periodically updates the BBS cycle and/or the PS.
A combiner 455 receives and combines the received power transmission signals from the power transmitter in the event that the receiver 400 has more than one antenna. The combiner can be any combiner or divider circuit that is configured to achieve isolation between the output ports while maintaining a matched condition. For example, the combiner 455 can be a Wilkinson Power Divider circuit. The rectifier 450 receives the combined power transmission signal from the combiner 455, if present, which is fed through the power meter 440 to the battery 420 for charging. The power meter 440 measures the received power signal strength and provides the control logic 410 with this measurement.
The control logic 410 also may receive the battery power level from the battery 420 itself. The control logic 410 may also transmit/receive via the communication block 430 a data signal on a data carrier frequency, such as the base signal clock for clock synchronization. The beacon signal generator 460 generates the beacon signal, or calibration signal, transmits the beacon signal using either the antenna 480 or 490 after the beacon signal is encoded.
It may be noted that, although the battery 420 is shown for as charged by and providing power to the receiver 400, the receiver may also receive its power directly from the rectifier 450. This may be in addition to the rectifier 450 providing charging current to the battery 420, or in lieu of providing charging. Also, it may be noted that the use of multiple antennas is one example of implementation and the structure may be reduced to one shared antenna.
In some embodiments, the control logic 410 and/or the IoT control module 425 can communicate with and/or otherwise derive IoT information from the device in which the wireless power receiver client 400 is embedded. Although not shown, in some embodiments, the wireless power receiver client 400 can have one or more data connections (wired or wireless) with the device in which the wireless power receiver client 400 is embedded over which IoT information can be obtained. Alternatively or additionally, IoT information can be determined and/or inferred by the wireless power receiver client 400, e.g., via one or more sensors. As discussed above, the IoT information can include, but is not limited to, information about the capabilities of the device in which the wireless power receiver is embedded, usage information of the device in which the wireless power receiver is embedded, power levels of the battery or batteries of the device in which the wireless power receiver is embedded, and/or information obtained or inferred by the device in which the wireless power receiver is embedded or the wireless power receiver itself, e.g., via sensors, etc.
In some embodiments, a client identifier (ID) module 415 stores a client ID that can uniquely identify the power receiver client in a wireless power delivery environment. For example, the ID can be transmitted to one or more chargers when communication are established. In some embodiments, power receiver clients may also be able to receive and identify other power receiver clients in a wireless power delivery environment based on the client ID.
An optional motion sensor 495 can detect motion and signal the control logic 410 to act accordingly. For example, when a device is receiving power at high frequencies, e.g., above 500 MHz, its location may become a hotspot of (incoming) radiation. Thus, when the device is on a person, e.g., embedded in a mobile device, the level of radiation may exceed acceptable radiation levels set by the Federal Communications Commission (FCC) or other medical/industrial authorities. To avoid any potential radiation issue, the device may integrate motion detection mechanisms such as accelerometers or equivalent mechanisms. Once the device detects that it is in motion, it may be assumed that it is being handled by a user, and would trigger a signal to the array either to stop transmitting power to it, or to lower the received power to an acceptable fraction of the power. In cases where the device is used in a moving environment like a car, train or plane, the power might only be transmitted intermittently or at a reduced level unless the device is close to losing all available power.
II. Portable Device Apparatus with Integrated Wireless Power Receiving Facilities
As shown in the example of
The housing 505 is configured to be removably attachable to a portable electronic device (not shown). In some embodiments, the housing 505 can be a sleeve that is removably attachable to the portable electronic device via one or more magnets, adhesives, clips, etc., including combinations or variations thereof. In some embodiments, the housing is designed in the form of a case or cover that cradles the portable electronic device. In some embodiments, the housing 505 is removably attachable to a portable electronic device by removing the back cover of the portable electronic device and attaching the housing 505. In such cases, the housing is designed with clips, e.g., plastic fasteners that are specifically designed to couple with the back cover of a specific device. In other embodiments, magnets can be used to attach the housing 505 to the portable electronic device. In yet other embodiments, the housing 505 can be designed to cradle the portable electronic device in a manner similar to a portable electronic protection cases. Example protection case embodiments are shown and discussed in greater detail with reference to
As shown in the example of
Among other functions, the RF circuitry 522 and the control circuitry 524 can perform the various control functions of a wireless power receiver as discussed in greater detail above with reference to
The wireless power reception apparatus 500 can have one or more power interfaces 540 over which power and, in some instances also data, can be exchanged between the battery 530 and/or circuitry 520 and the portable electronic device when they are removably attached.
The user interface 550 can include an interface configured to provide information to a user of a portable electronic device and/or an interface configured to allow the user of the portable electronic device to provide information to the wireless power reception apparatus 500. In some embodiments, light emitting diodes (LEDs) can be used to indicate various statuses of the wireless power reception apparatus 500. For example, an LED can emit a particular color to indicate each battery charging state (e.g., low, med, or high) for battery 530. The user interface 550 can also include one or more user buttons or switches. For example, an ON/OFF switch can be provided on the wireless power reception apparatus 500 to control whether or not the apparatus should process wireless power. In other examples, a button can be provided that, once pressed, activates charging of the one or more batteries of a portable electronic device using the energy stored in the one or more batteries 530 of the wireless power reception apparatus 500. Other user interface embodiments are also possible.
In the example of
Although not shown, in some embodiments, the mobile phone sleeve 620 can be configured to inductively charge the mobile device 610 in addition to or in place of connecting the devices over the power cord or cable 645.
The wireless power reception apparatus 700A includes a battery 730A, a control board 724 and an antenna/RF board 722. The battery 730A and the control board 724 are connected via a connection (e.g., wires) 725A and the control board 724 and the antenna/RF board 722 are connected via a connection (e.g., flex cable) 735. Similarly, the wireless power reception apparatus 700B includes a battery 730B and a combined control board and antenna/RF board 740 that are connected via a connection (e.g., wires) 725. Although not necessarily shown to scale the wireless power reception apparatus 700B can save real estate using the combined control and an antenna/RF board 740 and thus utilize a larger battery 730B.
As discussed in greater detail below, the antenna 810 can be configured to have various polarizations such as linear (both horizontal and vertical) or circular. The antenna/RF board 800 and/or other components of a wireless power reception apparatus can, among other features, dynamically determine the optimal polarization of the antenna 810. An example illustrating dynamic selection of the optimal polarization of the antenna is shown and discussed in greater detail with reference to
The bottom view of antenna/RF board 800 shown in
To begin, at step 1010, the wireless power reception apparatus configures the antenna(s) based on a first of multiple antenna polarity configurations or modes. Initially, the wireless power reception apparatus configures the antenna polarity to a “default” or base mode. As discussed herein, the wireless power reception apparatus includes one or more antennas having configurable polarity. In some embodiments, the polarity is configured by adjusting, e.g., activating or deactivating, antenna feeds. An example is shown and discussed in greater detail with reference to
At step 1012, the wireless power reception apparatus receives power from a wireless power transmission system, e.g., wireless charger. At step 1014, the wireless power reception apparatus processes the received wireless power and measures a quantity or amount of wireless power received. Alternatively or additionally, the wireless power reception apparatus may measure the signal strength of the received wireless power signals. In some embodiments, the wireless power reception apparatus saves and/or otherwise stores the measured power or signal strength measurement in conjunction with the antenna polarity mode.
At decision step 1016, the wireless power reception apparatus determines if the wireless power reception apparatus has cycled through each of the antenna polarity modes. If not, the process continues at step 1010 with the wireless power reception apparatus configuring the next antenna polarity configuration. However, if the wireless power reception apparatus has cycled through each of the antenna polarity modes, at step 1018, the wireless power reception apparatus selects an optimal polarity configuration or antenna polarity mode. As discussed herein, the optimal antenna polarity is the polarity at which the wireless power reception apparatus receives the most wireless power or the strongest signal from one or more chargers within a wireless power delivery environment. Lastly, at step 1020, the antennas are configured based on the selected antenna polarity configuration if they are not already configured in the selected mode.

A wireless client as discussed herein is configured to fit into the wireless client recess 1110. The battery in the battery recess 1115 is charged by wireless power received and processed by the wireless client. In operation, the wireless client receives RF wireless power, rectifies the power, and transmits the power to the mobile device (e.g., phone) battery via the client connection interface 1120 (e.g., 5V and Ground pins). In some embodiments, the case does not have a battery and the wireless client (wireless power receiver) provides power to itself and to the mobile device (e.g., phone) battery via the client connection interface 1120 (e.g., 5V and Ground pins).
In some embodiments, the case has a battery that powers the mobile device (e.g., phone) via the client connection interface 1120 (e.g., 5V and Ground pins). In this case, the wireless client (wireless power receiver) provides rectified power to the case battery which, in turn, provides the mobile device (e.g., phone) battery with power through the client connection interface 1120.
The wireless power receiver client can be a power receiver clients 103 of
In the example of
The processor may be, for example, a conventional microprocessor such as an Intel Pentium microprocessor or Motorola power PC microprocessor. One of skill in the relevant art will recognize that the terms “machine-readable (storage) medium” or “computer-readable (storage) medium” include any type of device that is accessible by the processor.
The memory is coupled to the processor by, for example, a bus. The memory can include, by way of example but not limitation, random access memory (RAM), such as dynamic RAM (DRAM) and static RAM (SRAM). The memory can be local, remote, or distributed.
The bus also couples the processor to the non-volatile memory and drive unit. The non-volatile memory is often a magnetic floppy or hard disk, a magnetic-optical disk, an optical disk, a read-only memory (ROM), such as a CD-ROM, EPROM, or EEPROM, a magnetic or optical card, or another form of storage for large amounts of data. Some of this data is often written, by a direct memory access process, into memory during execution of software in the computer 1500. The non-volatile storage can be local, remote, or distributed. The non-volatile memory is optional because systems can be created with all applicable data available in memory. A typical computer system will usually include at least a processor, memory, and a device (e.g., a bus) coupling the memory to the processor.
Software is typically stored in the non-volatile memory and/or the drive unit. Indeed, for large programs, it may not even be possible to store the entire program in the memory. Nevertheless, it should be understood that for software to run, if necessary, it is moved to a computer readable location appropriate for processing, and for illustrative purposes, that location is referred to as the memory in this paper. Even when software is moved to the memory for execution, the processor will typically make use of hardware registers to store values associated with the software, and local cache that, ideally, serves to speed up execution. As used herein, a software program is assumed to be stored at any known or convenient location (from non-volatile storage to hardware registers) when the software program is referred to as “implemented in a computer-readable medium”. A processor is considered to be “configured to execute a program” when at least one value associated with the program is stored in a register readable by the processor.
The bus also couples the processor to the network interface device. The interface can include one or more of a modem or network interface. It will be appreciated that a modem or network interface can be considered to be part of the computer system. The interface can include an analog modem, isdn modem, cable modem, token ring interface, satellite transmission interface (e.g. “direct PC”), or other interfaces for coupling a computer system to other computer systems. The interface can include one or more input and/or output devices. The I/O devices can include, by way of example but not limitation, a keyboard, a mouse or other pointing device, disk drives, printers, a scanner, and other input and/or output devices, including a display device. The display device can include, by way of example but not limitation, a cathode ray tube (CRT), liquid crystal display (LCD), or some other applicable known or convenient display device. For simplicity, it is assumed that controllers of any devices not depicted in the example of
In operation, the computer system 1500 can be controlled by operating system software that includes a file management system, such as a disk operating system. One example of operating system software with associated file management system software is the family of operating systems known as Windows® from Microsoft Corporation of Redmond, Wash., and their associated file management systems. Another example of operating system software with its associated file management system software is the Linux operating system and its associated file management system. The file management system is typically stored in the non-volatile memory and/or drive unit and causes the processor to execute the various acts required by the operating system to input and output data and to store data in the memory, including storing files on the non-volatile memory and/or drive unit.
Some portions of the detailed description may be presented in terms of algorithms and symbolic representations of operations on data bits within a computer memory. These algorithmic descriptions and representations are the means used by those skilled in the data processing arts to most effectively convey the substance of their work to others skilled in the art. An algorithm is here, and generally, conceived to be a self-consistent sequence of operations leading to a desired result. The operations are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like.
It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise, as apparent from the following discussion, it is appreciated that throughout the description, discussions utilizing terms such as “processing” or “computing” or “calculating” or “determining” or “displaying” or the like, refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage, transmission or display devices.
The algorithms and displays presented herein are not inherently related to any particular computer or other apparatus. Various general purpose systems may be used with programs in accordance with the teachings herein, or it may prove convenient to construct more specialized apparatus to perform the methods of some embodiments. The required structure for a variety of these systems will appear from the description below. In addition, the techniques are not described with reference to any particular programming language, and various embodiments may thus be implemented using a variety of programming languages.
In alternative embodiments, the machine operates as a standalone device or may be connected (e.g., networked) to other machines. In a networked deployment, the machine may operate in the capacity of a server or a client machine in a client-server network environment or as a peer machine in a peer-to-peer (or distributed) network environment.
The machine may be a server computer, a client computer, a personal computer (PC), a tablet PC, a laptop computer, a set-top box (STB), a personal digital assistant (PDA), a cellular telephone, an iPhone, a Blackberry, a processor, a telephone, a web appliance, a network router, switch or bridge, or any machine capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that machine.
While the machine-readable medium or machine-readable storage medium is shown in an exemplary embodiment to be a single medium, the term “machine-readable medium” and “machine-readable storage medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more sets of instructions. The term “machine-readable medium” and “machine-readable storage medium” shall also be taken to include any medium that is capable of storing, encoding or carrying a set of instructions for execution by the machine and that cause the machine to perform any one or more of the methodologies of the presently disclosed technique and innovation.
In general, the routines executed to implement the embodiments of the disclosure, may be implemented as part of an operating system or a specific application, component, program, object, module or sequence of instructions referred to as “computer programs.” The computer programs typically comprise one or more instructions set at various times in various memory and storage devices in a computer, and that, when read and executed by one or more processing units or processors in a computer, cause the computer to perform operations to execute elements involving the various aspects of the disclosure.
Moreover, while embodiments have been described in the context of fully functioning computers and computer systems, those skilled in the art will appreciate that the various embodiments are capable of being distributed as a program product in a variety of forms, and that the disclosure applies equally regardless of the particular type of machine or computer-readable media used to actually effect the distribution.
Further examples of machine-readable storage media, machine-readable media, or computer-readable (storage) media include but are not limited to recordable type media such as volatile and non-volatile memory devices, floppy and other removable disks, hard disk drives, optical disks (e.g., Compact Disk Read-Only Memory (CD ROMS), Digital Versatile Disks, (DVDs), etc.), among others, and transmission type media such as digital and analog communication links.
Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise,” “comprising,” and the like are to be construed in an inclusive sense, as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to.” As used herein, the terms “connected,” “coupled,” or any variant thereof, means any connection or coupling, either direct or indirect, between two or more elements; the coupling of connection between the elements can be physical, logical, or a combination thereof. Additionally, the words “herein,” “above,” “below,” and words of similar import, when used in this application, shall refer to this application as a whole and not to any particular portions of this application. Where the context permits, words in the above Detailed Description using the singular or plural number may also include the plural or singular number respectively. The word “or,” in reference to a list of two or more items, covers all of the following interpretations of the word: any of the items in the list, all of the items in the list, and any combination of the items in the list.
The above detailed description of embodiments of the disclosure is not intended to be exhaustive or to limit the teachings to the precise form disclosed above. While specific embodiments of, and examples for, the disclosure are described above for illustrative purposes, various equivalent modifications are possible within the scope of the disclosure, as those skilled in the relevant art will recognize. For example, while processes or blocks are presented in a given order, alternative embodiments may perform routines having steps, or employ systems having blocks, in a different order, and some processes or blocks may be deleted, moved, added, subdivided, combined, and/or modified to provide alternative or subcombinations. Each of these processes or blocks may be implemented in a variety of different ways. Also, while processes or blocks are, at times, shown as being performed in a series, these processes or blocks may instead be performed in parallel, or may be performed at different times. Further, any specific numbers noted herein are only examples: alternative implementations may employ differing values or ranges.
The teachings of the disclosure provided herein can be applied to other systems, not necessarily the system described above. The elements and acts of the various embodiments described above can be combined to provide further embodiments.
Any patents and applications and other references noted above, including any that may be listed in accompanying filing papers, are incorporated herein by reference. Aspects of the disclosure can be modified, if necessary, to employ the systems, functions, and concepts of the various references described above to provide yet further embodiments of the disclosure.
These and other changes can be made to the disclosure in light of the above Detailed Description. While the above description describes certain embodiments of the disclosure, and describes the best mode contemplated, no matter how detailed the above appears in text, the teachings can be practiced in many ways. Details of the system may vary considerably in its implementation details, while still being encompassed by the subject matter disclosed herein. As noted above, particular terminology used when describing certain features or aspects of the disclosure should not be taken to imply that the terminology is being redefined herein to be restricted to any specific characteristics, features, or aspects of the disclosure with which that terminology is associated. In general, the terms used in the following claims should not be construed to limit the disclosure to the specific embodiments disclosed in the specification, unless the above Detailed Description section explicitly defines such terms. Accordingly, the actual scope of the disclosure encompasses not only the disclosed embodiments, but also all equivalent ways of practicing or implementing the disclosure under the claims.
