Patent GB-1365174-A (GB)
Title: Transmission systems
IPC: G08C15/12
Filed: 1972-05-16
Abstract: 1365174 Selective signalling PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 16 May 1972 [19 May 1971] 22954/72 Heading G4H A system which transmits variations rather than instantaneous values of an input, to update (increment/decrement) a stored value at the receiver, can be calibrated in that the stored value is set to a maximum or minimum value if the updating causes the maximum or minimum to be exceeded. A multiplexing switch 9 is controlled by an address generator 13 to select control circuits 1 ... 1' in turn for connection to a circuit 10 having a differential amplifier 11 and resistive feedback 12, so that capacitor 6 in the selected control circuit, e.g. 1, is charged/discharged via the feedback 12 to a voltage corresponding to the setting of a potentiometer 5 in the control circuit, producing an output pulse from the amplifier 11 of duration representing the amount of charge delivered and polarity representing the polarity of the charging/discharging, this output pulse thus representing the change in the setting of the potentiometer 5 since the last time the control circuit was selected. In A/D converter 14, the output pulse gates clock pulses from 16 into a counter and the count is inserted into a shift register 15 together with a bit indicating the polarity of the change and the address from the address generator 13. The shift register contents are applied via a transmission path 19 to receivers 20-22, each controlling a respective TV camera, together with bits to select one of the receivers. At the selected receiver, e.g. 20, the contents of register 15 are shifted into a shift register 31 and the address portion is compared, 33, with part 24 2  of a clock-driven counter 24 also addressing a store 25, equality stopping part 24 2  and shifting out register 31 to an addersubtractor 34. Concurrently, part 24 1  of counter 24 reads out the bits of the location of store 25 addressed by part 24 2  via a delay 35 to adder-subtractor 34 where the count representing the change in potentiometer setting is added to or subtracted from (depending on the polarity bit in register 31) the value from store 25, the result being returned to store 25 via a shift register 36. A high order carry or borrow at 34 causes unit 37 to insert all ones or all zeros in register 36, depending on the polarity bit from register 31. This feature is used in calibrating the system, i.e. ensuring that the values stored at 25 correspond to the potentiometer settings absolutely (as distinct from changes merely corresponding to changes), which is done by setting the potentiometer 5 to its two extremes in turn. The TV camera is controlled by the outputs of store 25 supplied via D/A converter 27 and demultiplexing switch 28 (controlled by counter part 24 2 ).
