Title: Vehicle equipment control with semiconductor light sensors
Inventor: PLANGGER DAVID L
IPC: B60Q1/08
Filed: 2000-01-24
Granted: 2007-09-18
Abstract: Equipment on automotive vehicle (20) is controlled by a system including at least one semiconductor light sensor (170) having variable sensitivity to light. Each light sensor generates a light signal (164) indicative of the intensity of light incident on the light sensor. Control logic (66) varies the sensitivity of the light sensor and generates equipment control signals (166) based on received light signals. Sensitivity of light sensors (170) may be varied by changing the integration time (228) for producing charge from light (176) incident on light transducers (178), by selecting between light transducers (178, 490, 500, 504) of different sensitivity within the light sensor (170), by using a light transducer (530) with a sensitivity that is a function of the amount of incident light (176), and the like. Controlled equipment includes devices such as automatically dimming rearview mirrors (24, 26), headlamps (44), and moisture removal means (38, 40, 42).

Abstract: A suspension system for a vehicle, having at least first and second shock absorbers. The first shock absorber has a first main piston, and the second shock absorber has a second main piston. The shock absorbers are motively linked such that when the first main piston retracts, the second main piston is also caused to retract. The first and second shock absorbers may be hydraulic shock absorbers, wherein the first shock absorber defines a first hydraulic chamber therein, and the second shock absorber defines a second hydraulic chamber therein, the first and second hydraulic chambers being connected with a hydraulic line, so that causing the first main piston to retract reduces the size of the first hydraulic chamber, which increases the size of the second hydraulic chamber, which then causes the second main piston to retract.
