Patent ID: 10009956

Abstract:
Digital mobile communications devices and methods for processing fingerprint signal for authenticating a user of a mobile device. Processing a touch screen generated signal into a processed touch screen control signal for controlling mobile devices. Processing in a mobile device a motion detector generated signal into a motion detector generated control signal, for navigation control of mobile device. Modulation and demodulation, transmission and reception of spread spectrum signals, Orthogonal Frequency Division Multiplexed (OFDM) signals and conversion of spread spectrum signals into OFDM signals. Received spread spectrum signals from 3G cellular systems are converted into OFDM signals and transmitted in a wireless network, e.g. a Wi-Fi network. Received OFDM signals, received in a first RF frequency band, are demodulated and in a repeater mode are re-transmitted in a cellular system or network in a second OFDM radio frequency band. One or more receivers and demodulators for receiving demodulating and processing received signals into location finder information. A video camera in mobile device generates video signal and transmits video signal with location finder information signal.
