  • Patent number: 6393263
    Abstract: A mobile communications terminal and system in which a time displayed by the terminal can be corrected based on a reference time, while an intentional offset time can be established at the terminal without modification of the reference time itself. When a reference time (Tst) is 12:00, a user may purposely make a setting of, for example, 12:05 as a present time (RTC) generated by a time-generating portion. Accordingly, when the reference time (Tst) reaches 13:00, the present time (RTC) generated by the time-generating portion should be 13:05 unless deviation has occurred. Consequently, when the present time (RTC) is, for example, 13:04, correction is necessary. However, correction of the reference time (Tst) 13:00 itself fails to take into consideration the intentional five-minute advance, and so the reference time (Tst) of 13:00 is corrected with an added differential (&Dgr;t) of five minutes to 13:05.

  • Patent number: 5689822
    Abstract: A wireless adapter for decoding information from a broadcast signal to which a radio is tuned. The radio emits a local signal that serves to identify the broadcast signal, and a coupling part in the vicinity of the radio responds to the local signal. The coupling part produces a tuning signal in response to the local signal, and the tuning signal is applied to an adapter receiver circuit so that the receiver circuit acquires the broadcast signal to which the radio is tuned. A decoder circuit then decodes information contained in the acquired broadcast signal. In one embodiment, the adapter can be mounted in a vehicle near the vehicle radio. When the radio is tuned to a station that encodes, e.g., RBDS radio text on a sub-carrier of its broadcast signal, the adapter will acquire the station's sub-carrier, and will display the text conveniently and safely.

  • Patent number: 4270209
    Abstract: A compressive receiver for developing a series of time-based identifying pulses corresponding to discrete received signals having various frequencies within a predetermined band of surveillance. A multiple local oscillator function is included, effectively dividing the predetermined band of interest into small frequency increments, each of these local oscillator signals being coded by a pseudo-random coded sequence (bi-phase code) of maximal length. Each frequency increment thus developed is coded by this sequence delayed by one bit duration as compared to that applied to the local oscillator frequency immediately preceding it. A mixer receiving input signals in the band of interest, and also the multiple local oscillator signals thus generated and coded, has its output processed by a passive correlator which provides pulses at times determined by the frequencies extant in the input signal.
