Abstract
The time and/or date display of a clock radio is settable remotely and automatically by a radio frequency information signal. The time and/or date display is initially set in manufacturing of the clock radio simultaneously to a plurality of clock radio units, and the display may also be adjusted with an adjusting radio frequency signal broadcast to a plurality of clock radio units simultaneously.
Claims15
A method of remotely setting a data display of a clock radio automatically comprising,
- transmitting an information signal remotely to a radio frequency receiver of said clock radio through a carrier frequency,
- demodulating said information signal to a data signal,
- processing said data signal with a microprocessor having logic circuit, internal memory and signal generating means and operative to analyze said data signal to generate an initial data to be stored in said clock radio.
A system for remotely setting a data display of a clock radio automatically comprising:
- a radio frequency receiver operative to receive an information signal including display data to be exhibited by a display device of said clock radio,
- a demodulator connected to said receiver and operative to demodulate said information signal from said receiver unit for generating a demodulated signal,
- a microprocessor connected to said demodulator and operative for analyzing said demodulated signal to generate a display driver signal for operating said display device to exhibit automatically said display data by said display device of said clock radio.
