Abstract: The present disclosure provides a communication and power transfer system, the system comprising a transmitter capable of emitting a signal (e.g. microwaves) and comprising a means for modulating the frequency of a signal to a frequency modulated signal, and a receiver, the receiver synchronized to be in resonance with the frequency modulated signal so as to be able to receive signal. Methods for using carrier wave for communication and power transfer are also provided. The present disclosure provides a secure communication and power transfer systems utilizing frequency modulated microwaves that are minimally absorbed by organic matter and can move through aqueous media.

Abstract: An apparatus and method for determining whether to perform a full band scan by using motion sensor data comprising determining if a user equipment has been stationary since the full band scan was last performed; determining if the user equipment has skipped full band scans more times than a skipped threshold; and if the user equipment has skipped full band scans more times than the skipped threshold, performing a full band scan, or if the user equipment has not skipped full band scans more times than the skipped threshold, performing a partial band scan or performing no scan.

Abstract: According to the invention, the terminal (10) includes means (20) for automatically supplying power to a component (15) of said terminal, said automatic power supply being controlled by means (20) for detecting movement of said terminal (10). Application to mobile terminals equipped with a radio interface.

Abstract: A system and method is disclosed for a personal radio recorder. The personal radio recorder allows for random access of communication signals by identifying a channel and time. The personal radio recorder is capable of concurrent reception, storage and playback of a complete spectrum of individual communication signals. A wide-band signal is received, and concurrently demodulated into a plurality of individual communication signals. These audio signals are identified by channel and time. Individual signals may be simultaneously played, paused, or stored for later playback. Compression may be used to make efficient use of storage. Storage may be fixed, removable, or a combination of both. The system is also capable of storing signals that are digitally formatted, and is compatible with existing analog or digital playback devices. The personal radio recorder may playback multiple channels of communications data, either previously recorded or currently broadcast, to multiple output stages at the same time.
