摘要： A single inductor multiple-input multiple-output (SI-MIMO) switching converter time-multiplexes different input power sources through only one inductor to provide multiple regulated output voltages, which can be used to power up different blocks of a portable electronic device (or whatever else it is used for) and at the same time to charge up a rechargeable battery. Power multiplexing is achieved by input switches that are also the switching elements of the switching converter, thus eliminating an additional power multiplexer.

摘要： An exponential charge pump uses a number of identical or similar charging stages, each having a first and second capacitor. During a first clock phase, the first capacitor of each stage is charged by the second capacitor of the preceding stage, and, during a complementary second clock phase, the positive plate of the first capacitor of each stage is pushed to an increased voltage by the first capacitor of the preceding stage and charges the second capacitor of the next stage to the increased voltage at the same time. A similar mechanism occurs to the second capacitors in each stage, but with complementary timing. The increased voltage of the first capacitor of the last stage is pumped to an output capacitor during the second clock phase, and the increased voltage of the second capacitor of the last stage is pumped to an output capacitor during the first clock phase.

摘要： A mobile device with full functionality is comprised of two or more hardware components. Each hardware component provides a subset of mobile device functionality. Full functionality includes transceiver communications, processing, non-volatile memory, power, input and output. A communications interface, whether wired or wireless means, is used to link the two or more components together to produce a fully functionally mobile device. One or more of the hardware components can be advantageously embedded in or proximate to a piece of jewelry, a garment, or a fashion accessory. Other non-portable hardware components, when available, can also be linked to two or more components of the mobile device to provide additional functionality.

摘要： System and methodologies for timing synchronization in a wireless communication system are provided herein. The provided systems and methodologies can utilize various timing synchronization algorithms and an associated state machine to reduce the down time of a wireless communication system due to the presence of simultaneously operating piconets (SOP) and/or other factors. Frequency band finger pattern detection techniques are additionally described that can reduce boundary mismatch rates for wireless receivers. In one example, by making use of the fact that time frequency codes (TFCs) possess unique frequency hopping patterns, system down time can be reduced and OFDM boundary matching can be enhanced to allow a receiver to obtain correct timing information even for communication channels having a very low SINR.

摘要： A mobile device facilitates customized services for its user. For example, a mobile device can record information about a user using multiple inputs (e.g., sensors, GPS, camera, etc.). The information recorded creates a log of activities and interests of the user. One or more parts of the log are published and the user receives additional information based on the published information, such as other nearby people with similar interests or coupons. Other services of the mobile device can include biometric (e.g., facial) recognition of people, voting/polling, and language translation. The services available on a mobile device can be pre-configured so that the user can use the various services out of the box.
