10. A communications device, comprising:
-
a housing; a wireless transceiver and processor carried by the housing and operative with each other; an input screen carried by the housing and comprising a plurality of spaced transceivers positioned at the input screen and connected to the processor wherein each transceiver is configured to transmit a millimeter wave RF signal and receive reflected signals from an object positioned close to the input screen, each transceiver comprising an oscillator and embedded antenna wherein the oscillator is configured to sweep an output frequency and reflected signals are received at a frequency lag producing an intermediate frequency (IF) signal; wherein said processor is configured to determine the location of the object relative to the input screen based on the reflected signals received at each transceiver and the offset of the IF frequency represents the distance of the object that reflects the signals. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
