摘要： A short distance, battery powered, amplitude modulated, crystal controlled RF transmitter for transmitting encoded security information. In its preferred embodiments, the transmitter comprises a novel fifth overtone crystal oscillator which self-produces a carrier frequency at the third harmonic of the fifth overtone of the crystal's fundamental frequency, which carrier frequency is coupled by a series resonant trap, or a pi network, tuned to the carrier frequency to an amplifier stage where the carrier is amplitude modulated via pulse position encoded binary security data. In an alternative embodiment, the transmitter comprises matched crystal oscillator, tripler and amplifier stages. Also disclosed is an antenna including a battery clip contact.

摘要： A transmitting-receiving station for transmitting information by frequency hopping comprises a code generator to define the use of a plurality of channels in accordance with a high-speed skip law for a transmitting-receiving station in the stand-by mode, the high-speed skip law consisting in the use of each of the channels during a period of time Tp, while the low-speed skip law governs the change of listening channels used during N.times.Tp, each corresponding to a center channel out of a sequence of N channels of the high-speed skip law. The center channel contains a synchronizing code. The station comprises a memory device to which a write circuit for progressively storing therein the codes produced by the generator and also to which a read circuit is connected to take the codes from the memory as a function of the positions of the transmitting-receiving station.

摘要： A modulator for RF class C amplifiers particularly suitable for transistor power stages employing FAIL-SOFT. Automatic modulation control operates to independently adjust the gains of a pair of controllable amplifiers whose outputs are then combined, filtered and applied to a class C stage. The output of the class C stage is sampled, linearly detected and processed to produce gain control time-voltage functions which compensate for class C pulse distortion so that a preserved amplified waveshape can be obtained.

摘要： A telephone subscriber station has a base set and a cordless hand set. The transmission between the base and hand set occurs by way of infrared transmitters and infrared receivers. Pulse phase modulation who is particularly suited for the speech transmission. Various functions are remotely controlled from the cordless hand set by the transmission of special characters. The special characters are transmitted as pulse sequences having differing frequencies. Thereby, a specific frequency is assigned to each special character. A call device comprises keys and a controllable pulse generator. A frequency recognition circuit is provided in the receiver at the base set and assigns the received pulse sequences to the special characters and has corresponding control functions. A monitoring circuit monitors the synchronization between the hand set and the base set and disconnects the telephone connection given a transmission which is disrupted over a longer interval.
