Abstract:
An electronic controller for a predetermined temperature coefficient heater provides solid state control of the application of power to the heater. In particular, a positive temperature coefficient glow plug wherein the heater is plated on a ceramic substrate glow plug is controlled by contactless solid state controller. The temperature of the glow plug is sampled by a clock signal and compared with a predetermined temperature value. Pulsed power is supplied to elevate and maintain the temperature of the heater to the predetermined value. In a complete motor vehicle engine wherein one glow plug is used in each cylinder, one glow plug is sampled and controls the remainder of the plugs.
Method And Apparatus For Determining The Velocity Of A Vehicle Body
An adjustable damping system (26) for an automotive vehicle (12) having a damper (10) and sensors (28, 30, 32) for determining the movement of the automotive vehicle (12) and generating a signal representing the movement of the automotive vehicle (12). The adjustable damping system (26) further includes a damper control logic unit 40 for automatically adjusting the damping characteristics of the damper (10) in response to the signal. The adjustable damping system (26) further includes a signal compensation unit (42) which is able to improve the accuracy with which signals representing the movement of the automotive vehicle (12) are determined.
