  • Patent number: 5164722
    Abstract: An electric remote control device (20) includes sliding pushers (27) associated two by two and actuated from an actuating member. Each pusher is associated with a converter for generating an electric signal, a parameter of which is representative of the movement and/or position of the pusher and a signal processor (33) processes the signal produced at the output of the converter. The device provides for storing a defining equation between the position of the actuating member and the parameter of the output signal and the device includes a first storage unit (35) for storing the value of the parameter of the output signal of the converter when the actuating member is in a neutral position, corresponding to zero movement of the pusher, and a second storage (36) unit for storing the value of the parameter of the output signal of the converter when the actuating member is in an endmost position corresponding to maximum movement of the pusher.

  • Patent number: 5160928
    Abstract: System for regulating the mean current flowing through a load (1), particularly an electric device controlling the phenomenon to be regulated, from initial variable control information (.alpha.), a DC voltage source (V.sub.alim) being provided for supplying this load, comprising: a measuring device (4) for permanently measuring the value of the variable information (.alpha.); a determination device (5, 6) for causing a mean theoretical current value to be applied to the load (1) to correspond to each value of the information (.alpha.
