摘要： The present teaching relates to collecting and processing location-specific wireless waveforms for use in wireless communication, components, methods, apparatuses, servers, and systems. In one embodiment, a disclosed system comprises a first wireless transceiver of a first device, and at least one second wireless transceiver of at least one second device. The first wireless transceiver of the first device is wirelessly coupled to the at least one second wireless transceiver through a wireless multipath channel associated with a space. The first device with the first wireless transceiver comprises a processor and a memory, which are configured to obtain a set of channel information (CI) and perform a task associated with the space based on the set of channel information. The set of channel information is captured when at least one probing signal is either (1) sent from the first wireless transceiver to a particular second wireless transceiver through the wireless multipath channel associated with the space, or (2) sent from the particular second wireless transceiver to the first wireless transceiver through the wireless multipath channel. The set of CI comprises a channel impulse response, a channel frequency response, a channel profile, and/or another channel data of the wireless multipath channel.

摘要： The present teaching relates to vital sign detection and monitoring based on channel state information (CSI). In one example, an apparatus for vital sign detection is disclosed. The apparatus comprises a receiver, a processor and a memory communicatively coupled with the processor. The receiver is configured for receiving at least one wireless signal from a multipath channel that can be impacted by a vital sign of at least one living being. The processor is configured for: extracting a time series of channel state information (CSI) for the multipath channel from the at least one wireless signal, obtaining one or more periodic fluctuations based on a spectral analysis of the time series of CSI, and determining whether the vital sign is present based on the one or more periodic fluctuations.

摘要： A binaural cochlear implant system (system) includes first and second microphones associated with first and second ears of a patient, respectively. The microphones detect an audio signal presented to the patient and output first and second signals representative of the audio signal as detected at the first and second ears, respectively. The system also includes a first sound processor that receives the first signal from the first microphone and the second signal from a second sound processor by way of a communiation link with the second sound processors. The first sound processor generates first and second fine structure signals representative of fine structure information of the first and second fine structure signals, respectively, and generates a timing pulse signal based on the first and second fine structure signals. The first sound processor uses the timing pulse signal to represent to the patient an interaural time difference between the first and second signals.
