<p>1392426 Remote control BROWN BOVERI & CIE AG 26 Sept 1973 [19 May 1973] 45107/73 Heading G4H In a method of shortening or condensing messages in receivers of centralized multiservice control systems by remote control, a receiver is reset to its off position when a reset pulse transmitted by a central station during a pulse interval coincides with a scanning pulse produced in the receiver. The central station sends a start pulse followed by a series of message pulses, the start pulse causing the generation, in the receiver, of a reference series of message pulses ("scanning pulses") which is compared with the transmitted series to perform a control action or equality. The central station may interpolate a reset pulse between any two of the message pulses (or lengthen one of the latter) and coincidence of this with any of a series of interpolated pulses in the reference series causes reset.</p> |
