摘要： A low impedance sensor includes thin conductive electrodes on a dielectric substrate and detects proximity of a target metal object or structure moving along defined path such as a track. The sensor includes a first conductive electrode pad having a closed, continuous geometric form and a second conductive electrode surrounding the first electrode and spaced from the first electrode by a channel of non-conductive dielectric. The first and second electrodes are optionally disposed on the same surface of the substrate. An integrated control circuit is located on the substrate proximate the first and second electrodes, and is electrically coupled to the first and second electrodes.

摘要： Equipment on automotive vehicle is controlled by a system including at least one semiconductor light sensor having variable sensitivity to light. Each light sensor generates a light signal indicative of the intensity of light incident on the light sensor. Control logic varies the sensitivity of the light sensor and generates equipment control signals based on received light signals. Sensitivity of light sensors may be varied by changing the integration time for producing charge from light incident on light transducers, by selecting between light transducers of different sensitivity within the light sensor, by using a light transducer with a sensitivity that is a function of the amount of incident light, and the like. Controlled equipment includes devices such as automatically dimming rearview mirrors, headlamps, and moisture removal means.

摘要： A control system for establishing grade and elevation control for a tool of a construction apparatus for maintaining the vertical position of the tool relative to a reference includes a first ultrasonic transducer configured to be carried by the construction apparatus, with the first transducer transmitting and receiving acoustic waves, at least one reflector, a second ultrasonic transducer configured to be carried by the construction apparatus, with the second transducer receiving acoustic waves, and a controller coupled to the first and second ultrasonic transducers which drive the transducers to produce an acoustic wave and monitors the time reflections of the acoustic wave are respectively received by the first and second transducers. The controller determines the local speed of sound based on a first in time reflection received by the second ultrasonic transducer and determines the distance from the construction tool to a reference based on the local speed of sound and a second in time reflection received by both the first and second ultrasonic transducers. The controller produces at least one electrical signal as a function of the distance of the ultrasonic transducers from the reference. In preferred form, the controller communicates the signal to a positioning device, which signal actuates the positioning device to adjust the position of the construction tool with respect to the reference.

摘要： A control for an excavator controls the position of the bucket cutting edge to a desired depth accurately by a calibrating laser receiving mounted on the excavator stick member and passed through a stationary laser plane wherever the stick is moved into or out of a trench. Linear position encoders monitor the length that the actuating cylinders are extended and lookup tables convert the encoder outputs to angle representations for determining the positions of the laser receiver and the cutting edge. Other lookup tables are utilized to avoid time-consuming iterative calculation procedures to provide real-time digital process solutions of trigonometric functions. The apparatus includes a unique laser receiver comprising a plurality of linearly aligned photo receptors with associated circuitry for producing an output representative of the receptor illuminated or, if a group of receptors are illuminated, the centermost receptor illuminated.

摘要： A simplified mirror sub-assembly for exterior automotive mirrors includes an electrochromic mirror element, a circuit board disposed on a rear surface of the mirror element, and a carrier plate attached to the circuit board via double-sided adhesive tape. The sub-assembly may include a conductive trace disposed on the surface of the circuit board that mates with the mirror element to dissipate heat generated by electronic components on the circuit board and act as a heater for the mirror element at the same time. The electronic components on the circuit board are arranged to lie in a void created by a peripheral edge in the carrier plate so that the inventive structure can incorporate a known carrier plate structure, if desired, to allow easy installation into a known mirror housing.
