Abstract: An optical moisture detector for determining a value corresponding to ambient light conditions and comparing that value to a predetermined value. The detector includes an optical moisture sensor and a processor. The optical moisture sensor can be a photo array, a CCD or a CMOS. The processor can be a microprocessor. The processor can emit a control signal to engage or disengage a light generating device based on the result of the comparison of the value to the predetermined value.

Abstract: A power drive system is adapted for a sliding door mounted on at least one side of a vehicle for sliding movement forwardly and rearwardly of the vehicle. The system includes a reversible motor. A bracket is guided within a guide along a fixed path between the opened and closed positions of the door. An elongated drive member is slidably disposed within the guide and connected to the bracket at one end for driving the bracket along the fixed path. A translator mechanism operably engages with the drive member for powering movement of the door. The translator mechanism can include a rotatable hub, operably engageable with the drive member, a gear transmission for driving the hub, and a clutch mechanism for connecting the motor to the transmission. The translator mechanism preferably has sufficient power to pull the sliding door into a primary latch position with respect to the corresponding portions of a latch mechanism attached to the door and frame defining the door opening.

Abstract: A closure system for a motor vehicle includes a closure, a closure frame, an electric motor, a control switch, an electric power source, first and second displacement sensors, temperature sensor, voltage sensor of the power source and a microprocessor. The first and second displacement sensors each operably generate a signal indicative of the one of closure movement and output shaft rotation. The microprocessor is electrically connected to the control switch, the electric motor, the first and second displacement sensors, the temperature sensor and the voltage sensor of the power source. The microprocessor includes electrically connecting the motor with the power source responsive to a condition of the control switch. The microprocessor also has means for converting temperature sensed to an electrical signal indicative of the temperature.

Abstract: A closure system for a motor vehicle includes a closure, a closure frame, an electric motor, a control switch, an electrical power source, first and second displacement sensors, a temperature sensor, a current sensor for a current being drawn by the electric motor, and a microprocessor. The first and second displacement sensors each operably generate a signal indicative of closure movement. The microprocessor is electrically connected to the control switch, the electric motor, the first and second displacement sensors, the temperature sensor and the current sensor. The microprocessor electrically connects the motor with the power source responsive to a condition of the control switch. The microprocessor also converts the temperature sensed to an electrical signal indicative of the temperature, and converts the current sensed to an electrical signal indicative of motor current.

Abstract: An error correcting code and apparatus are used in conjunction with a main memory in which a data word is stored in a plurality of circuits each of which produces multiple outputs. A minimum number of check bits are stored together with the data word for detecting and correcting single bit errors and detecting the existence of multi-bit errors. A parity bit for the entire data word is also stored. For a 32-bit data word, at least 3 bits of the data word are stored in each of 10 memory circuits. Seven check bits and one parity bit are also stored in the 10 memory circuits wherein no more than one of the check bits or parity bit is stored in any one memory circuit. Upon reading the data word from the memory a set of verify check bits and a verify parity bit are generated and compared to the stored check bits and stored parity bit to produce a check bit syndrome and a parity bit syndrome.
