Abstract: Methods, apparatus and systems for wireless monitoring and tracking are described. In one example, a described method of a wireless monitoring system comprises: transmitting a wireless signal that is impacted by a wireless multipath channel in a venue and a modulation of an object undergoing a motion in the venue, to obtain a set of channel information (CI) of the wireless multipath channel; performing a monitoring task by monitoring the object and the motion; determining a plurality of admissible system states of the wireless monitoring system, wherein each admissible system state is associated with a respective setting of at least one of: the wireless signal, a series of sounding signals in the wireless signal, or the monitoring task; choosing one of the admissible system states to be a system state of the wireless monitoring system based on the monitoring task; and applying a setting associated with the chosen admissible system state to the wireless monitoring system.

Abstract: Methods, apparatus and systems for powering a wireless monitoring system are described. In one example, a described method comprises: positioning and powering a transmitter at a first location in a venue; positioning and powering a receiver at a second location in the venue; transmitting a wireless signal from the transmitter through a wireless multipath channel of the venue; receiving the wireless signal by the receiver through the wireless multipath channel, wherein the wireless signal is impacted by the wireless multipath channel and a modulation of an object undergoing a motion in the venue; obtaining a set of channel information (CI) of the wireless multipath channel based on the wireless signal; and monitoring the object and the motion of the object based on the set of CI.

Abstract: Methods, apparatus and systems for vehicle wireless monitoring are described. In one example, a described method comprises: transmitting a first wireless signal from a first wireless device through a wireless multipath channel of a venue, the venue comprising a vehicle and an immediate vicinity of the vehicle; receiving a second wireless signal by a second wireless device in the venue through the wireless multipath channel, wherein the second wireless signal differs from the first wireless signal due to the wireless multipath channel and a modulation by an object undergoing a motion in the venue; obtaining a time series of channel information (TSCI) of the wireless multipath channel based on the second wireless signal; and performing a monitoring task by monitoring, based on the TSCI, at least one of: the vehicle, the object or the motion of the object.

Abstract: A method and system for providing an “Always-On” Internet device is disclosed. The Always-On Internet device can be turned on constant due to its use of low power components, while a conventional PC cannot afford to. The Internet device acts as a “hub” for all the network and peripheral connections of the PC. The Internet device can be connected to the Internet and then connected to the conventional PC. The PC's keyboard, video monitor, and mouse connections are re-directed to the Internet device, which then connects to the PC at the PC's keyboard, video and mouse connectors. The Internet device has a switching gear unit that KVM functionality and Internet Connection Sharing, the control of which is transferred between the PC and the Internet device, depending on whether the PC is on or off.
