Abstract: A radio frequency identification (RFID) tag is disclosed that comprises a transceiver and a component coupled to the transceiver. The component is adapted to collect at least one biological parameter. The transceiver is adapted to wirelessly receive power from a base device, where the power received from the base device is used to power the component.

Abstract: A hearing assist device (10) for a person (P). The device comprises a speaker device (SP1) for presenting sound to an ear canal of the person and circuitry for identifying a specified area relative to the person. The device further comprises a first microphone (M1) for providing a first sound signal in response to a first sound source located inside the area and in response to a second sound source located outside the area. Further, the device comprises a second microphone (M2) for providing a second sound signal in response to the first sound source and the second sound source. Still further, the device comprises circuitry (16) for determining a position of the first sound source and the second sound source in response to the specified area, the first sound signal and the second signal. Finally, the device comprises circuitry (16) for outputting a processed signal in response to the position.

Abstract: According to one embodiment of the present invention, a digital hearing device is disclosed. The digital hearing aid includes a microphone for receiving sound, which may include an analog signal. The analog signal is converted by a first converter into a digital signal. Filters are provided to divide the digital signal into multiple signal parts. A signal processor may be provided for each signal part, and performs signal processing on its respective signal part. An adder adds the output of the signal processors, which results in a processed digital signal. A second converter converts the processed digital signal back into an analog signal. A speaker then outputs the analog signal. According to another embodiment of the present invention, a method for enhancing sound is provided.
