摘要： A remote control arrangement uses pulse code modulation for transmission as in infrared remote control arrangements. A feature of the arrangement is that only one quartz oscillator is necessary and is used in the receiver part. The receiver measures the first pulse width transmitted and, dependent on that, defines the measured period of a control circuit. A primary feature is that the arrangement is provided with a prepulse having a threefold pulse width before the start pulse thereby allowing the preamplifier of the receiver to be in its normal operating area when the start pulse occurs.

摘要： A remote control system for use in remote controlling a television receiver is provided in which a light signal is used as the remote control signal. An electroluminescent diode is used to emit the remote control light signal which is amplitudemodulated by a modulating frequency in the ultrasonic frequency range and has a very narrow band of wave lengths. The remote control system is very compact in size and completely free from the erratic operations caused by the noise.

摘要： For the wireless remote control of an RF receiver having a remote control signal processing portion, the RF receiver being capable of being switched between an off state, an on state and an enabled state in which a channel is not being received but the remote control signal processing portion is operative, the remote control processing portion includes a remote control signal receiver unit and a memory circuit connected to receive signals from the receiver unit and to convert them into voltages which operate the RF receiver, and there is provided a remote control signal transmitter having a button or key for each channel and arranged to transmit, upon actuation of a given button, a carrier signal which is pulse modulated with a number of pulses corresponding to the selected channel. The memory circuit has one location for each such channel and an additional location which can produce an output voltage to switch the receiver from its on state to its enabled state. Only one memory location can produce an output voltage at any given time.
