A vehicular movement indicator safety system consisting of motion and status sensors on the dynamic moving systems of a vehicle, a programmed microprocessor control unit, and conventional signal indicators. The microprocessor is programmed to integrate data from sensors related to wheel, steering, brake, engine and transmission systems to determine the exact nature of changes in vehicular movement resulting from operation of one or more of the dynamic systems, to distinguish between a driver's signaled intent to turn or make a change in vehicular movement and the actual onset of the turn or change as determined by concurrent activation of dynamic systems, and to immediately activate signal indicators to produce clear, unambiguous and readily perceived signals corresponding to the changes in vehicular movement. The vehicular movement indicator safety system generates instantaneous signals alerting drivers to a change, eliminates the uncertainty, ambiguity and confusion prevalent with existing turn signal and brake indicator systems, and significantly enhances ability of drivers to quickly perceive and react to changes in movement of other vehicles in substantially all traffic situations and under adverse as well as normal visibility and weather conditions.

Vehicular movement indicator safety system

A mechanically actuable switch having associated electronic circuitry contained within the switch housing, including circuitry operative to selectively provide momentary, alternate action, and multistation switching modes. Included within the switch housing are a voltage/current regulator, initializing logic, contact debounce logic, mode control circuitry, output buffers, an LED driver and an LED. The switch contact is typically a preformed wire spring configured to be pivoted about a central point from one state of actuation to another. The switch is operable over a wide operating voltage range, typically 3 to 18 volts.

Universal logic switch

A subminiature rotary coded switch having a dual-in-line configuration. Flexible contacts making electrical connection with the dual-in-line terminals of the switch are mounted within a stationary body. A drum-shaped detenting cover has printed circuitry on its inner cylindrical surface, typically in the form of a flexible printed circuit board. The cover rotates the flexible board with respect to the body, producing a wiping action with respect to the flexible contacts, thereby producing the desired switching operations. Each such switch can be electrically equivalent to four single-pole double-throw switches and two of the switches of this invention can be mounted in one conventional 14-terminal dual-in-line array of holes in a printed circuit board.
