Abstract: A method and apparatus for reducing the surface temperature of a large body of water by pumping deeper cooler water to an area near the surface. The deeper cooler water can be pumped using a self-deploying pump which is powered by waves which travel across the surface of the large body of water.

Abstract: Capacitive sensors used to detect force upon a transparency product for detecting and discriminating crash characteristics of a vehicle, as well as capacitive sensors used in conjunction with a conductive panel functioning as an airbag cover and ground plane for the capacitive sensors. The capacitive sensors are made up of electrodes, of which one may be a conductive coating. The capacitive sensors can be arranged upon a substrate and can include a reference sensor. Long term effects of temperature upon sensor output are compensated for with an algorithm comparing constant desired sensor output to low frequency drift due to temperature effects. Moisture upon a transparency product is distinguished from a nearby object due to the capacitance sensed. A sleep detection algorithm detects when a vehicle operator is drowsy. A capacitive sensor array having a nested circle sensor and L-shaped sensors, along with a dummy sensor is used in a sunroof-equipped vehicle for sensing occupant head position.

Abstract: A capacitive sensor array wherein the plurality of electrodes and the power and data lines communicating with the electrodes are formed from a single dielectric substrate. One face of the substrate is a grounded area, with the electrodes and power and data lines formed from the substrate on the opposite face. A ground connector connects the grounded areas on the two faces without a need to penetrate the substrate. The substrate is flexible, and the power and data lines are die cut from a portion of the substrate to form an integrated cable.

Abstract: A system for detecting impairment of operating ability of transportation vehicle operators due to sleepiness, intoxication or other causes, and for sounding an alarm when operator impairment is found. The invention employs an array of at least three dual electrode capacitive coupling sensors, placed in the headliner above the operator's seat, which sense operator head position and motion. Outputs from the sensors, after suitable processing and amplification, are analyzed by a microprocessor to determine the operator's head position and motion, through triangulation analysis of distances from the operator's head to each sensor. The microprocessor records, tracks and compares the operator head motion data to profiles of normal head motion and impaired head motion, to detect any head motion indicative of operator impairment.

Abstract: An overhead-mounted air bag deployment system, having overhead sensors and a microprocessor to measure and analyze passenger motion as well as vehicle deceleration, for consideration by the microprocessor in deciding whether to deploy the air bag, so as to deal with case-to-case variations in passenger motion. The system also has both a warning light and a warning sleeve on the steering wheel, to discourage the driver from remaining in a position involving an increased risk of injury, and has an automatic bag release means to release the air bag and free the passenger when the collision is over.
