摘要： An apparatus and method is related to providing sensing functions that are similar to “human touch” when located in a prosthetic device such as a BION microstimulator that is implanted in a patient. The apparatus includes a power circuit, a communication circuit, and a sensor circuit. The power circuit provides power to the communication circuit and the sensor circuit. The sensor cooperates with the communication circuit, which communicates to the brain. The sensor uses various techniques to detect changes in the environment for the surrounding tissue using criteria such as reflectivity, impedance, conductivity, return signal spectrum, return signal rate, and return signal phase to name a few. For example, the impedance observed by the sensor changes when: the skin tissue is deformed around the sensor, or when the skin is surrounded by water. The sensory information is interpreted by the brain as an analog of touch or feel.

摘要： An apparatus and method is related to wireless communication devices with a reduced-noise recording receiver. The recording receiver receives a transmitted signal, converts the received signal to a digital base-band signal and stores the digitized base-band signal in a buffer for subsequent processing. The stored digital signals are subsequently processed to recover the transmitted data signal. The overall signal integrity in the receiver is improved by performing signal processing after reception is complete. The IF processing section of the receiver includes a frequency band translation section. The frequency band translation section translates the frequency band of the IF signal into a non-harmonically related frequency band. Since the IF signal is in an unrelated frequency band, data can be recovered from the transmission signal with improved signal-to-noise characteristics. At least a portion of the non-essential electronics are disabled during reception to avoid additional interference and sources of noise.

摘要： A system and method that facilitates multiple systems of communicating devices, i.e., a master device and one or more implantable slave devices, to coexist on a common, e.g., RF, communication channel having a limited temporal bandwidth while maintaining the required update rate between each master device and its associated slave devices. In embodiments of the present invention, master devices periodically transmit one or more beacon messages that are suitable for identification by other such master devices at a communication range greater than the communication range that may cause interference between systems and thus enabling one or more systems to cause the position of its frame periods to be interleaved with the frame periods of other such systems in anticipation of systems moving in closer proximity and actually interfering with each other.

摘要： Described is a system and method for providing a synchronization pattern in a communication system. The method includes generating a synchronization pattern with good randomness properties; packing a signal for transmission with m headers, each header consisting of the synchronization pattern 1/m symbol-time shifted from the previous header; and transmitting the signal. A further method provides for the sampling the transmitted signal with m headers of symbol-time shifted synchronization patterns; and determining symbol timing offset by computing and reordering correlation peaks from the synchronization patterns. A system includes a transmitting system, a receiving system, and a data channel. The transmitted signal includes m headers with 1/m symbol-time shifted synchronization patterns. The receiving system undersamples the transmitted signal with m synchronization patterns to simulate an oversampled synchronization pattern.
