    摘要： Methods, apparatus and systems for power supply design of a wireless monitoring system or device are described. In one example, an accessory of a wireless monitoring system is described. The accessory comprises at least one physical attachment feature attaching the accessory to at least one of: a first wireless device in the wireless monitoring system or a second wireless device in the wireless monitoring system. The first wireless device is configured for transmitting a first wireless signal through a wireless multipath channel of a venue. The second wireless device is configured for receiving a second wireless signal through the wireless multipath channel. The second wireless signal differs from the first wireless signal due to the wireless multipath channel that is impacted by a motion of an object in the venue. The wireless monitoring system comprises a processor configured for: obtaining a time series of channel information (TSCI) of the wireless multipath channel based on the second wireless signal, and monitoring the motion of the object in the venue based on the TSCI.

    摘要： Methods, apparatus and systems for radio-based sleep tracking are described. In one example, a described system comprises: a transmitter configured to transmit a first wireless signal through a wireless multipath channel in a venue; a receiver configured to receive a second wireless signal through the wireless multipath channel, wherein the second wireless signal differs from the first wireless signal due to the wireless multipath channel which is impacted by a sleeping motion of an object in the venue; and a processor. The processor is configured for: obtaining a time series of channel information (TSCI) of the wireless multipath channel based on the second wireless signal, wherein each channel information (CI) of the TSCI comprises N1 components, wherein N1 is a positive integer larger than one, computing N1 component-wise analytics each associated with one of the N1 components of the TSCI, identifying N2 largest component-wise analytics among the N1 component-wise analytics, wherein N2 is a positive integer less than N1 computing at least one first motion statistics based on the N2 largest component-wise analytics of the TSCI, and monitoring the sleeping motion of the object based on the at least one first motion statistics.

    摘要： Methods, apparatus and systems for monitoring a presence or a motion of an object in a proximity of an apparatus are described. In one example, a described apparatus is in a venue for wireless proximity monitoring. The apparatus comprises: a transmitter, a receiver, and a processor. The transmitter is configured for transmitting a wireless signal through a wireless multipath channel, wherein the wireless multipath channel is impacted by a motion of an object within a proximity of the apparatus. The receiver is configured for: receiving the wireless signal through the wireless multipath channel between the transmitter and the receiver, and obtaining a time series of channel information (TSCI) of the wireless multipath channel based on the wireless signal received by the receiver. The processor is configured for monitoring the motion of the object within the proximity of the apparatus based at least partially on the TSCI.

    摘要： Methods, apparatus and systems for providing automatic assistance based on wireless monitoring are described. In one example, a described automatic assistant system comprises: a transmitter, a receiver, a processor, and an assistant device. The transmitter is configured for transmitting a first wireless signal through a wireless multipath channel of a venue. The receiver is configured for receiving a second wireless signal through the wireless multipath channel. The second wireless signal differs from the first wireless signal due to the wireless multipath channel that is impacted by a motion of an object in the venue. The processor is configured for: obtaining a time series of channel information (TSCI) of the wireless multipath channel based on the second wireless signal, and monitoring the motion of the object in the venue based on the TSCI. The assistant device is configured for generating an assistance with respect to the object in the venue based on the monitoring.
