Abstract: The present invention is a monitor that detects generator core 12 hot spots where the insulation between ferromagnetic sheets is breaking down by monitoring rotor 10 shaft voltage. The difference between the differential shaft voltage at each end of the rotor 14 produces a voltage signal that changes as the core 12 malfunctions. By comparing signal samples over time, core failure can be detected. Spring loaded rotor shaft brushes 20 and 22 connected to differential isolation amplifiers 24 and 26 obtain the voltage between ends 16 and 18 of the rotating shaft and nearby frame, and a differential amplifier 28 produces the difference between the shaft end differential voltages which is the shaft dissymmetry voltage. An analog-to-digital converter 30 produces digital values of the dissymmetry voltage which can be converted into a voltage frequency spectrum by a Fourier Transform routine executed by a computer 32 or analyzed directly.

Abstract: A device is disclosed for controlling a variable electric signal. A first switch receives the monitored variable electric signal at its input. A second switch receives a first limit electrical signal for the monitored signal and a first minimum reference for the first limit electric signal. A third switch receives a second limit electric signal for the monitored signal and a second maximum limit reference for the limit electric signal. The first switch delivers at its output: the monitored signal when it is between the output signals of the second and third switches; the output signal of the second switch when the monitored signal is greater than the latter signal; and the output signal of the third switch when the monitored signal is less than the latter signal.

Abstract: A universal trailer lighting adapter permits connection of the lighting systems of American trailers to either American or foreign motor vehicles. Circuitry employing complementary metal oxide semiconductor logic elements in cooperation with solid state switches results in negligible current drain from the motor vehicle battery when the motor vehicle is not in use. The circuitry is powered directly from the battery of the motor vehicle, thereby eliminating additional loading of the motor vehicle electrical components and wiring and assuring full brightness of on both the motor vehicle and the trailer. The circuitry is fused or current limited to protect the electrical systems of both the motor vehicle and trailer from shorts that may occur in the trailer lighting system. A light emitting diode is provided to indicate a malfunction in either the adapter circuitry or the trailer lighting system to the driver of the motor vehicle.

Abstract: More efficent encoding/decoding in decomposing and recomposing a high resolution image is obtained by employing a unique pixel cluster arrangement. The pixel clusters of an image are classified as one of a plurality of classifications. A unique encoding/decoding technique is assigned to each classification. In one embodiment, a cluster including at least one high resolution pixel to be recomposed from a corresponding low resolution pixel which is a so-called exception to general prediction rules is classified as a first classification. A cluster including no pixels which are exceptions is classified as a second classification. Supplemental information is encoded/decoded for all pixels in a cluster classified as the first classification. Pixels in the cluster classified as the second classification are encoded/decoded according to the general prediction rules.

Abstract: A method of updating the reference count in a period shift measurement vehicle detector permits conditional reference count updating in the No Call direction whenever the sample count minus reference count difference value lies between the upper limit of a jitter/vibration guard and band and a positive freeze reference threshold. Decrementing of the reference count is permitted in the call direction whenever the sample count minus reference count lies in a range from 0 to a negative freeze reference threshold. Variable hysteresis for call/no call signal generation is provided in a single vehicle detector, with the call direction threshold selectable between two values.

Abstract: An auxiliary control circuit for controlling taillights, especially the brake light and turn signal lights, of a vehicle is provided. The circuit is designed to function such that, when the brake of the vehicle is applied, the brake light blinks continuously for the length of time that the brake is applied. At the same time, the turn signal lights simultaneously blink in an alternating fashion for enhancing warning effect. When the brake is applied and the turn signal switch is actuated for the purpose of providing a turning indication, the brake light and the turn signal lights work independently in the usual manner.
