Description

AREA OF TECHNOLOGY

[0001] The present disclosure relates to the field of charging electric and / or hybrid vehicles. In particular, embodiments of the present disclosure relate to an integrated portable spare wheel and tire charging system. GENERAL STATE OF THE ART

[0002] Static wireless charging for electric and hybrid vehicles is an emerging technology. This technology allows an electric or hybrid vehicle to charge while parked over a charging pad. However, fully wireless charging systems often exhibit lower efficiency compared to traditional plug-in chargers.

[0003] Proper alignment between the vehicle and the charging pad is desirable for efficient power transfer. Misalignment can significantly reduce charging efficiency, and large air gaps between the charging pad and the vehicle can also impair power transfer. Additionally, conventional wireless charging systems for vehicles are bulky, making them less practical for portable charging applications. SUMMARY

[0004] The present disclosure describes systems and methods for a portable inductive spare wheel and tire charging system.

[0005] Embodiments of the present disclosure provide a method for using a portable spare wheel and tire charging system. For example, a method may involve aligning a first vehicle over (e.g., in close proximity to) an inductive charging source and having the first vehicle place a portable inductive spare wheel and tire charging device over the inductive charging source. The method further involves the first vehicle disconnecting from the portable inductive spare wheel and tire charging device. The method may then involve placing a second vehicle near the portable inductive spare wheel and tire charging device. Thereafter, the portable inductive spare wheel and tire charging device receives power from the inductive charging source and transfers the power to the second vehicle.

[0006] In another scenario, a system may include a first vehicle and a portable inductive spare wheel and tire charger attached to the first vehicle. The system further includes an inductive charging source. The first vehicle of the system is configured to align itself over (e.g., in close proximity to) the inductive charging source and position the portable spare wheel and tire charger over the inductive charging source. The first vehicle then physically and electrically disconnects from the portable spare wheel and tire charger and moves away from the inductive charging source.

[0007] In yet another scenario, a vehicle may be provided. The vehicle includes a portable inductive spare wheel and tire charger, one or more sensors, and one or more processors coupled to the one or more sensors. The vehicle is operable to detect, using the one or more sensors, one or more alignment features associated with an inductive charging source and to align itself over (e.g., in close proximity to) an inductive charging source using the one or more alignment features. The vehicle can then place (e.g., position) the portable inductive spare wheel and tire charger over the inductive charging source and move away from the portable inductive spare wheel and tire charger.

[0008] These and other benefits of the present revelation are provided in detail in this document. BRIEF DESCRIPTION OF THE DRAWINGS

For example, the various sensors of the vehicle sensor system 232 may be integrated into the various subsystems of the vehicle 102, such as mirrors, roof, etc., or be attached to the vehicle 102 using a suitable mounting mechanism. In some embodiments, the various sensors of the vehicle sensing system 232 can be located on the front, rear, sides, top, bottom, and underside of the vehicle 102. The location of a sensor may depend on its function. For example, a sensor that monitors the area under the vehicle may be connected to a floor surface of the vehicle 102, while a sensor that can monitor an area on any side of the vehicle 102 may be mounted on or integrated into the doors of the vehicle 102. The vehicle sensing system 232 may also include one or more sensors, such as cameras, lidar, and / or accelerometers, which are coupled to various mechanical components and / or systems of the vehicle 102.It is understood by experts that the sensors can be coupled to the vehicles in various ways and at locations other than those mentioned above.

[0021] In some embodiments, the VCU 210 can control operational aspects of the vehicle and implement one or more sets of instructions received from the server 104, the user device 112, or from one or more sets of instructions stored in the memory 204.

In some embodiments, the user device 112 can function as the HMI interface for the vehicle 102.

[0027] In some embodiments, the vehicle 102 may include a battery charging and control unit 242. The battery charging and control unit 242 may include a battery management system that (i) continuously monitors the state of charge (SOC), state of health (SOH), and temperature of the battery cells, (ii) ensures that all battery cells are balanced to prevent discharge or deep discharge, which can wear out the cells, and (iii) protects against overvoltage, undervoltage, overcurrent, and thermal runaway.The battery charging and control unit 242 can further include a power conversion mechanism that converts alternating current (AC) from the mains or any other charging device into direct current (DC) required by the battery and manages the voltage levels within the vehicle, ensuring that the vehicle's high-voltage battery can power low-voltage systems such as lights and infotainment. The battery charging and control unit 242 can also include thermal management devices, such as cooling and heating systems, to maintain optimal battery temperature and operating conditions. In one embodiment, the working memory 204 can store battery algorithms related to predictive maintenance and optimization for the high-voltage battery.

[0028] Certain computing modules may be omitted from the computer system architecture of the 208 vehicle computer and / or the VCU 210. It goes without saying that the in Fig. The computing environment shown in Figure 2 is an example of a possible implementation according to the present disclosure and should therefore not be considered restrictive or exclusive.

[0029] In addition to the components mentioned above, the Vehicle 102 may have numerous mechanical systems and subsystems. A chassis or frame may form the backbone of the Vehicle 102, supporting the body and other components. The Vehicle 102 may include an engine that converts fuel into mechanical power, thus propelling the vehicle forward. The engine includes various components, such as the engine block, pistons, valves, and spark plugs. The Vehicle 102 may also include a transmission system. The transmission system transfers the engine's power to the wheels. It includes, among other components, the clutch, gearbox, driveshaft, and differentials. The transmission adjusts the power output according to the vehicle's speed and load. The Vehicle 102 may also include a suspension system.The suspension system absorbs shocks and maintains contact between the tires and the road, providing a smooth ride. It includes components such as springs, shock absorbers, and linkages. The Vehicle 102 also includes a vehicle stopping system that allows the driver to slow down or stop the Vehicle 102. This includes components such as pedals, master cylinder, lines, and brake pads or shoes. The Vehicle 102 also includes a steering system that allows the driver to steer the vehicle. The steering system includes components such as the steering wheel, steering column, rack and pinion, and tie rods. The Vehicle 102 may also include an exhaust system that removes and filters the exhaust gases produced by the engine. This includes, among other things, the exhaust manifold, catalytic converter, muffler, and exhaust pipe.The vehicle 102 also includes a cooling system that prevents the engine and / or battery from overheating. It includes components such as the radiator, water pump, thermostat, and coolant. The vehicle 102 also includes a fuel storage and delivery system. This includes the fuel tank, fuel pump, fuel filter, and fuel injectors. The vehicle 102's electrical system provides power to the car's electrical components. It may include the battery, alternator, starter motor, and wiring. The heating, ventilation, and air conditioning (HVAC) system controls the temperature inside the vehicle 102. It includes the heater core, blower motor, and air conditioning compressor.In some embodiments, the vehicle can be an electric vehicle (EV) or a hybrid vehicle, and in each case, some of the aforementioned components would be replaced by an electric motor and a high-voltage battery. When all the mechanical components work together, they ensure that the vehicle operates optimally.

[0030] The conventional method for charging electric or hybrid vehicles involves plugging the vehicle into a wall socket or a dedicated charging station, such as a Stage II charger or a standard high-voltage charger. In all these cases, the chargers are stationary and fixed in a specific location, such as a garage or parking space. To charge a vehicle, it must be driven to one of these charging stations, and a power cable is physically plugged into a charging port on the vehicle. Recently, some mobile charging robot systems have been proposed; however, these mobile charging systems are inefficient and not integrated into the vehicle, and therefore suffer from some of the same disadvantages as the conventional stationary charging systems.

[0031] Embodiments of the present disclosure provide a portable charging system integrated into the spare wheel of a vehicle, thereby creating a compact and portable charging system that remains with the vehicle and can serve as a charging source for the vehicle's high-voltage battery. Additionally, this integrated portable spare wheel charging system can be detached from the vehicle and used to charge other vehicles and accessories, thus providing a versatile charging system.

[0032] Fig. Figure 3 illustrates an integrated portable spare wheel charging system 300 according to an embodiment of the present invention. Most vehicles, such as pickup trucks, SUVs, etc., have a spare wheel included in the vehicle. While the inclusion of full-size spare wheels in vehicles has steadily declined, many vehicles still include a smaller spare wheel. The portable spare wheel charging system 300 can include a wheel 304 surrounded by a tire 302. The wheel 302 can include one or more standard components, such as a rim, spokes, cylinder, valve stem, bolt holes, and center cap. The portable spare wheel charging system 300 further includes an inductive charging device 306. The inductive charging device 306 can include a receiver coil that detects the alternating magnetic field and converts it into AC voltage.The inductive charging device 306 can further include a receiver rectifier circuit that converts the induced AC voltage into DC voltage. The inductive charging device 306 can also include a voltage control that ensures the DC voltage is suitable for charging the vehicle's high-voltage battery. The DC voltage can be supplied by the portable spare wheel charging system 300. Fig. Figure 4 illustrates a cross-sectional view of the portable spare wheel charging system 300. As can be seen, the inductive charging device 306 can be located in the center of the wheel 304. In one embodiment, the inductive charging device 306 can be integrated into the center cap and spokes of the wheel 304. The integrated portable spare wheel charging system 300 can be integrated into the vehicle 102 in one of several ways. In one embodiment, the integrated portable spare wheel charging system 300 can be mounted on the underside of the vehicle 200 using a spare wheel lifting device. In another embodiment, the integrated portable spare wheel charging system 300 can be located in the trunk of the vehicle 102. In yet another embodiment, the integrated portable spare wheel charging system 300 can be mounted on a rear door of the vehicle 102.In another embodiment, the integrated portable spare wheel loading system 300 can be mounted on the roof of the vehicle 102 or placed in a dedicated compartment inside the vehicle 102 in the interior of the vehicle 102.

[0033] Fig. Figure 5 illustrates the use of an integrated portable inductive spare wheel and tire charging system 400 according to an embodiment of the present disclosure. The integrated portable inductive spare wheel and tire charging system 400 can include a spare wheel 402 that has an integrated inductive charging device. The inductive charging device can have a receiver coil 404 that is mounted on a surface of the spare wheel 402 and exposed to the external environment of the spare wheel 402. In some embodiments, the receiver coil is integrated into the spare wheel 402, and in other embodiments, the receiver coil is detachably coupled to the spare wheel 402. The integrated portable inductive spare wheel and tire charging system 400 can also include a power cable 410 that is detachably attached to one end of an output port of the inductive charging device of the spare wheel 402.The other end of the power cable 412 can include a suitable connector to fit a charging port 412 of the vehicle 102. In operation, the vehicle 102 can drive over a floor 406 and position itself over (not shown) an inductive charging source 408, which in certain embodiments may be located under or on the floor 406. The inductive charging source 408 can include a transmitter coil that generates an electromagnetic field when an alternating current flows through it. The inductive charging source 408 can also include a power supply that converts AC from the mains into the appropriate voltage and current levels required by the transmitter coil and provides electrical power to the transmitter coil.The inductive charging source 408 can also include a control unit to manage the power transfer between the transmitter and receiver coils using communication and control protocols.

[0034] Once the vehicle is positioned over the inductive charging source 408, it can automatically position itself, or a user of the vehicle can position the spare wheel 402 such that the receiver coil 404 of the integrated portable inductive spare wheel and tire charging system 400 is aligned over the transmitter coil of the inductive charging source 408. The vehicle 102 can then be parked at a distance from the inductive charging source 408. In some embodiments, the vehicle can autonomously drive itself to a parking location. The distance at which the vehicle can park may depend on the length of the power cable 410. Once the vehicle 102 is parked at the suitable location, the inductive charging source 408 can then begin transferring power to the integrated portable inductive spare wheel and tire charging system 400.In some embodiments, the integrated portable inductive spare wheel and tire charging system 400 can transfer power via the power cable 410 to the vehicle 102 to charge the vehicle battery. In other embodiments, the integrated portable inductive spare wheel and tire charging system 400 can transfer power via the power cable 410 to a different vehicle 102 (than the one that contains the charging system 400) to charge the battery of the other vehicle 201. In other embodiments, the integrated portable inductive spare wheel and tire charging system 400 can also include a power storage device and a transmitter coil.In this case, once the power storage device of the integrated portable inductive spare wheel and tire charging system 400 is fully charged, the integrated portable inductive spare wheel and tire charging system 400 can be inductively coupled to the vehicle 102 via its transmitter coil, which is aligned with a receiver coil of the vehicle 102 and connected to the vehicle 102's battery. Once coupled to the vehicle, the integrated portable inductive spare wheel and tire charging system 400 can transfer power from its power storage device to the vehicle battery via its transmitter coil and the vehicle's receiver coil. Once charging is complete, the integrated portable inductive spare wheel and tire charging system 400 can be reattached to the vehicle 102.

[0035] In some embodiments, the inductive charging source 408 can be controlled by a remote server (e.g., server 104). In this case, as soon as the vehicle 102 (or the user of the vehicle 102) places the spare wheel 402 over the inductive charging source 408, as described above, and / or when the power cable 410 is connected to the vehicle charging port 412, the vehicle can send a message to the remote server indicating that the spare wheel 402 has been placed over the inductive charging source 408. In other cases, as soon as the spare wheel 402 is placed over the inductive charging source 408, the remote server can detect the placement of the spare wheel 402 over the inductive charging source 408 (e.g., via sensors coupled to the inductive charging source 408 and / or the spare wheel 402 and the remote server).Once the remote server receives the message from the vehicle or detects its placement, it can send a message to the inductive charging source 408 to activate it. Upon activation, the inductive charging source 408 can begin transferring power to the integrated portable inductive spare wheel and tire charging system 400.

[0036] Fig. 6A and Fig. Figure 6B illustrates the use of the integrated portable inductive spare wheel and tire charging system according to another embodiment of the present disclosure. In this embodiment, the vehicle 102 includes an inductive spare wheel and tire charging device 502, which includes a receiver coil 504. In one embodiment, the inductive spare wheel and tire charging device 502 may be mounted on the underside of the vehicle 102. In other embodiments, the inductive spare wheel and tire charging device 502 may be located inside the trunk or another area of ​​the vehicle 102. In this embodiment, the vehicle 102 may drive over an inductive charging source 510, which may be located under or on a floor 508. The inductive charging source 510 may have a similar structure to the inductive charging source 408 described above.In order for the vehicle to drive over the inductive charging source 510, the vehicle 102 may require a minimum ground clearance between its underside and the ground 508. For vehicles that may not have the required ground clearance, the inductive spare wheel and tire charging device 502 may be arranged such that driving over the inductive charging source 510 is not necessary.

[0037] To optimize energy transfer from the inductive charging source 510 to the inductive spare wheel and tire charging device 502, it is important to correctly align the receiver coil 504 with the transmitter coil of the inductive charging source 510. Since the inductive charging source 510 is located under the floor and the inductive spare wheel and tire charging device 502 is located under the vehicle 102, it can be difficult for the vehicle driver to determine the correct orientation for the vehicle 102 in order to properly align the receiver coil 504 with the transmitter coil. To assist the vehicle driver 102 in correctly aligning the receiver coil 504 with the transmitter coil of the inductive charging source 510, one or more alignment markers 506 can be placed on the floor 508.These alignment features assist in the correct alignment of the vehicle 102 so that the receiver coil 504 is properly aligned with the transmitter coil of the inductive charging source 510. In one embodiment, the alignment features 506 can be specialized tags that can be detected by an underbody camera of the vehicle 102. The vehicle 102's HMI system can display these tags on a screen associated with the HMI system, and the driver can use the tags to guide the vehicle 102 correctly. In another embodiment, ultrasonic sensors on the vehicle 102 can read / detect ultrasonic emissions from a transmitter placed on the ground 508 to provide guidance to the driver of the vehicle to correctly align the vehicle 102 over the inductive charging source 510. In yet another embodiment, vehicle radar can be used to locate the inductive charging source 510.

[0038] Once the vehicle 102 is correctly aligned over the inductive charging source 510, the driver of the vehicle 102 can initiate a process to lower the inductive spare wheel and tire charging device 502 towards the ground. In some embodiments, the vehicle 102 can initiate this process automatically without driver intervention as soon as the vehicle is correctly aligned over the inductive charging source 510. In one embodiment, the vehicle 102 can only initiate the process of lowering the inductive spare wheel and tire charging device 502 if the vehicle 102 has detected that it is in a parked state. The inductive spare wheel and tire charging device 502 can be mounted on a spare tire carrier 602. The spare tire carrier 602 can be extended towards the floor 508 to move the inductive spare wheel and tire charging device 502 closer to the inductive charging source 510.Once the receiver coil 504 is at the correct distance from the transmitter coil of the inductive charging source 510, or when the receiver coil 504 is in physical contact with the transmitter coil of the inductive charging source 510, the extension of the spare wheel carrier 602 can be stopped. After the vehicle 102 has determined that the spare wheel carrier 602 has extended to the correct distance, the vehicle 102 can send a message to a controller of the inductive charging source 510. In one embodiment, the remote server 104 can act as the controller of the inductive charging source 510. After the controller receives the message from the vehicle 102, it can enable power to be supplied to the inductive charging source 510. The inductive spare wheel and tire charging device 502 can then begin receiving power.

[0039] In one embodiment, the inductive spare wheel and tire charging device 502 can have its own power storage device, such as a battery. In other embodiments, the inductive spare wheel and tire charging device 502 can be powered via a power cable (e.g., the one in Fig. The power cables 410 (illustrated in Figure 5) are connected to the high-voltage battery of the vehicle 102. The vehicle 102 can then charge its high-voltage battery via the inductive spare wheel and tire charging device 502. Once charging is complete or otherwise stopped, the spare tire carrier 602 can be retracted, and the inductive spare wheel and tire charging device 502 is moved back to its standard position. In some embodiments, the vehicle 102 can send another message to the controller of the inductive charging source 510, indicating the end of the charging session. The controller can then stop power being supplied to the inductive charging source 510.

[0040] Fig. Figure 7 illustrates the use of an inductive spare wheel and tire charging device 702 according to another embodiment of the present invention. In this embodiment, an inductive charging source 706 can be positioned above a floor 708. The inductive spare wheel and tire charging device 702 can include a receiver coil 704. In this case, since the inductive charging source 706 is positioned above the floor, there is, among other things, no need to lower the inductive spare wheel and tire charging device 702. For vehicles with the correct ground clearance, the vehicle 102 can be positioned over the inductive charging source 706. Once the vehicle is correctly positioned, the receiver coil 704 is automatically at the correct distance from the transmitter coil of the inductive charging source 706.In some embodiments, the inductive charging source 706 may be able to be raised above the base 708 to ensure the correct distance between the receiver coil 704 and the transmitter coil of the inductive charging source 706, or to ensure that the receiver coil 704 is in physical contact with the transmitter coil of the inductive charging source 706.

[0041] Fig. Figure 8 is a flowchart for a process 800 for charging a vehicle using an inductive spare wheel and tire charging device according to an embodiment of the present invention. In one embodiment, the process 800 can be performed by the vehicle 102 alone or by the vehicle 102 in conjunction with the server 104. In step 802, a first vehicle is aligned over a ground-based inductive charging source. The ground-based inductive charging source can be located either above or below the ground, as described above. In step 804, the first vehicle can align the inductive spare wheel and tire charging device with the ground-based inductive charging device so that power transfer can begin.In step 806, the vehicle can position the inductive spare wheel and tire charger over the ground-based inductive charger by lowering the charger onto the ground-based charger. Once the inductive spare wheel and tire charger is in physical contact with the ground-based inductive charger or positioned at the correct distance from it, the ground-based charger can begin transferring power to the inductive spare wheel and tire charger in step 808. The inductive spare wheel and tire charger can then transfer power to the first vehicle's battery in step 810.

[0042] In another embodiment, the first vehicle may not need to be charged. Instead, in step 812, the first vehicle can place the inductive spare wheel and tire charger on the ground-based inductive charging source and physically and electrically disconnect itself from the charger. After physically and electrically disconnecting from the charger, the first vehicle can move away from the location in step 814, either driven by a user or autonomously. Then, in step 816, a second vehicle can be placed near or above the charger. The charger can then be electrically connected to the second vehicle in step 818 (e.g., using the power cable as described above).After the second vehicle is coupled to the inductive spare wheel and tire charging device, the ground-based inductive charging source can begin transferring power to the inductive spare wheel and tire charging device at step 820. The inductive spare wheel and tire charging device can then transfer power to the second vehicle at step 822. Thus, the inductive spare wheel and tire charging device can be used to charge multiple vehicles. In some cases, after the charging session is complete, the inductive spare wheel and tire charging device can be physically attached to the second vehicle (or another vehicle). The second vehicle can then transport the inductive spare wheel and tire charging device to another location to be used for charging other vehicles.This will improve the current vehicle charging infrastructure and provide greater flexibility when charging electric and / or hybrid vehicles.

[0043] Fig. Figure 9 shows a block diagram of an example control server 900 (e.g., the control server 104 of the Fig.1) on which one or more arbitrary techniques (e.g., methods) can be performed, or which can perform the methods described above in connection with the vehicle 102, according to one or more exemplary embodiments of the present disclosure. In other embodiments, the Server 900 can be operated as a standalone device or be connected (e.g., networked) to other servers. In networked use, the Server 900 can function as a server machine, a client machine, or both in server-client network environments. In one example, the Server 900 can function as a peer server in peer-to-peer (P2P) (or other distributed) network environments.Server 900 can be a personal computer (PC), a tablet PC, a set-top box (STB), a personal digital assistant (PDA), a mobile phone, a smart key fob, a wearable computing device, a web device, a network router, a switch or bridge, or any machine capable of executing instructions (sequentially or otherwise) specifying actions to be performed by this server, such as a base station. Furthermore, although only a single server is illustrated, the term "server" can also be understood to include any collection of servers that, individually or collectively, execute a set (or multiple sets) of instructions to perform one or more of any of the methodologies discussed in this document, such as cloud computing, software as a service (SaaS), or other computer cluster configurations.

[0044] Examples, as described in this document, may include or operate with logic or a set of components, modules, or mechanisms. Modules are tangible units (e.g., hardware) capable of performing operations specified during operation. A module includes hardware.

In another example, the hardware may include configurable execution units (e.g., transistors, circuits, etc.) and a computer-readable medium containing instructions, the instructions configuring the execution units to perform a specific task when they are operated. This configuration may occur under the guidance of the execution units or a loading mechanism.Accordingly, the execution units are communicatively coupled to the computer-readable medium when the device is operated. In this example, the execution units can be an element of more than one module. For instance, during operation, the execution units can be configured by a first set of instructions to execute a first module at one time and reconfigured by a second set of instructions to execute a second module at a second time.

[0045] The server (e.g., the computer system) 900 may include a hardware processor 902 (e.g., a central processing unit (CPU), a graphics processing unit (GPU), a hardware processor core, or any combination thereof), main memory 904, and static memory 906, some or all of which may communicate with each other via a coupling (e.g., a bus) 908. The server 900 may further include a graphics display device 910, an alphanumeric input device 912 (e.g., a keyboard), and a user interface (UI) navigation device 914 (e.g., a mouse). In an example, the graphics display device 910, the alphanumeric input device 912, and the UI navigation device 914 may be a touchscreen display. The server 900 may additionally include a storage device (i.e., a memory card).The server 900 may include a drive unit 916, a network interface device / transmitter 920 coupled to antenna(s), and one or more sensors 928, such as a global positioning system (GPS) sensor, a compass, an accelerometer, or another sensor. The server 900 may include an output controller 934, such as a serial (e.g., Universal Serial Bus (USB)), parallel, or other wired or wireless (e.g., infrared (IR)) near field communication (NFC) connection, etc., for communicating with or controlling one or more peripheral devices (e.g., a printer, a card reader, etc.).

[0046] The storage device 916 can include a machine-readable medium 922 on which one or more sets of data structures or instructions (e.g., software) are stored, embodying or utilizing one or more of any of the techniques or functions described herein. The instructions may also reside, wholly or at least partially, within the main memory 904, within the static memory 906, or within the hardware processor 902 during their execution by the server 900. In an example, any one or any combination of the hardware processor 902, the main memory 904, the static memory 906, or the storage device 916 can constitute machine-readable media.

[0047] Although machine-readable medium 922 is illustrated as a single medium, the term "machine-readable medium" can include a single medium or multiple media (e.g., a centralized or distributed database and / or associated caches and servers) configured to store the one or more instructions.

[0048] Various embodiments can be implemented wholly or partially in software and / or firmware. This software and / or firmware can take the form of instructions contained in or on a non-transferable, computer-readable storage medium. These instructions can then be read and executed by one or more processors to enable the execution of the operations described herein. The instructions can be in any suitable form, including but not limited to source code, compiled code, interpreted code, executable code, static code, dynamic code, and the like.Such a computer-readable medium can include any tangible, non-transient medium for storing information in a form readable by one or more computers, such as, but not limited to, read-only memory (ROM); random access memory (RAM); magnetic disk storage media; optical storage media; flash memory, etc.

[0049] The term “machine-readable medium” can include any medium capable of storing, encoding, or carrying instructions for execution by the Server 900, and causing the Server 900 to perform one or more of any of the techniques disclosed herein, or capable of storing, encoding, or carrying data structures used by or associated with such instructions. Non-restrictive examples of machine-readable media can include semiconductor memory and optical and magnetic media. In one example, a machine-readable medium with mass includes a machine-readable medium with a plurality of particles that has a rest mass. Specific examples of machine-readable media with mass can include non-volatile working memory, such as semiconductor memory devices (e.g.,electrically programmable read-only memory (EPROM) or electrically erasable programmable read-only memory (EEPROM) and flash memory devices; magnetic disks, such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks.

[0050] Instructions can also be transmitted or received via a communication network using a transmission medium through the Network Interface Device / Transceiver 920, utilizing any of a number of transmission protocols (e.g., Frame Relay, Internet Protocol (IP), Transmission Control Protocol (TCP), User Datagram Protocol (UDP), Hypertext Transfer Protocol (HTTP), etc.). Examples of communication networks include, but are not limited to: a local area network (LAN), a wide area network (WAN), a packet data network (e.g., the Internet), mobile phone networks (e.g., cellular networks), analog telephone networks (POTS networks), and wireless data networks (e.g., the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, known as Wi-Fi®, and the 802.11 standard).16 of the IEEE, known as WiMAX®), the IEEE 802.15.4 standards group, and peer-to-peer (P2P) networks. In one example, the Network Interface Device / Transmitter 920 can include one or more physical jacks (such as Ethernet, coaxial, or telephone jacks) or one or more antennas for connecting to the communications network. In another example, the Network Interface Device / Transmitter 920 can include multiple antennas for wireless communication using at least one single-input multiple-output (SIMO), multiple-input multiple-output (MIMO), or multiple-input single-output (MISO) technique.The term "transmission medium" shall be understood to include any intangible medium capable of storing, encoding, or carrying instructions for execution by the Server 900, and including digital or analog communication signals or other intangible media to facilitate communication between such software.
