The present invention relates to monitoring and automatic control systems.

Monitoring and automatic equipment control systems

The present invention relates to improved image sensor-processor interconnections and to monitoring and automatic control systems incorporating the improved image sensor-processor interconnections.

A height control valve for a suspension leveling system includes a control unit and a valve assembly. The control unit can include a servo powered by a servo current, the servo being coupled to the valve assembly with a linkage. The control unit also can include a controller in communication with the servo and adapted to sense a change in the servo current when the linkage fully engages the valve assembly to reconfigure the valve assembly to a desired supply, exhaust and/or closed position. Based on the change in servo current, the controller can determine a selected distance to move or reconfigure the valve assembly, with distance being independent of any wear or tolerance in the linkage or elsewhere. The control unit can also include an actuator, the movement of which is sensed by a non-contact sensor that is in communication with the controller.

Height control valve for vehicle leveling system

The present invention relates to various apparatus, algorithms and methods for acquiring and processing images of a scene. Details of various aspects of the associated images are identified and may be utilized to generate various vehicular equipment control signals.

Image acquisition and processing methods for automatic vehicular exterior lighting control

An imaging system of the invention includes an image array sensor including a plurality of pixels. Each of the pixels generates a signal indicative of the amount of light received on the pixel. The imaging system further includes an analog to digital converter for quantizing the signals from the pixels into a digital value. The system further includes a memory including a plurality of allocated storage locations for storing the digital values from the analog to digital converter.

Image processing system to control vehicle headlamps or other vehicle equipment

An imaging system of the invention includes an image array sensor including a plurality of pixels. Each of the pixels generates a signal indicative of the amount of light received on the pixel. The imaging system further includes an analog to digital converter for quantizing the signals from the pixels into a digital value. The system further includes a memory including a plurality of allocated storage locations for storing the digital values from the analog to digital converter. The number of allocated storage locations in the memory is less than the number of pixels in the image array sensor. According to another embodiment, an imaging device includes an image sensor having a plurality of pixels arranged in an array; and a multi-layer interference filter disposed over said pixel array, said multi-layer interference filter being patterned so as to provide filters of different colors to neighboring pixels or groups of pixels.
