  • Patent number: 4610179
    Abstract: A remote manual shift control device having a manually operable range selector lever for controlling the operation of solenoids, relays and the like of an electrically controlled transmission, in which the selector lever is mechanically coupled to shift a code slide member to positions corresponding to the range positions, and wherein it coacts with switching components to generate binary coded output signals corresponding to the respective range positions as determined by the shift lever. The control device embodies a unitized sealed electronic module containing an IC Decoder Unit for the binary signals with inhibit and latch control terminals; and a connected Logic and Buffers Unit for determining the proper driving connections with the transmission control devices at the transmission.

  • Patent number: 4025843
    Abstract: A control circuit for compensating for the change in drive current in a pe-width modulated control circuit of a power supply. Cos Mos three input NOR gates are controlled by applying an analog voltage proportional to the charge in drive current to the third input. A negative feedback loop is then provided to compensate for changing temperature.
