Abstract : A controller for a locked carrier distributed multiplexed telemetry system which uses on-off switching of a d.c. power supply and a pilot signal generator at a remote control unit. A pilot signal from the remote control unit is amplified and rectified. The d.c. rectifier output, occurring only during the presence of the pilot signal, is sensed by a comparator which provides rapid transition pulses to advance a counter. The counter is advanced one count for each pilot signal cycle (on-off-on) and is reset for each d.c. power supply cycle (on-off-on). The devices to be controlled are connected to the output of the counter. (Patent)
