ABSTRACT:
An electronically-active vehicle gear-shift knob (10) consisting of a hand-grasping section (12), an electronics enclosure (44) that is attached to an upper edge (14) of the hand-grasping section (12), and an electronics control circuit (90) consisting of a transmitting circuit (92) and a remotely located receiving circuit (94). The enclosure (44) includes a set of four pushbutton switches (92E) that are connected to the transmitting circuit (92). The closure of any one of the pushbutton switches (92E) allows the transmitting circuit (92) to produce an RF output signal (19) that is radiated via an antenna (92H) to the receiving circuit (94). The receiving circuit (94) subsequently processes the RF output signal (19) and produces an output control signal (29) that energizes an LED light corresponding to the specific pushbutton switch (92E)that has been closed.
