摘要： A non-contacting type sensor and method for sensing angular position are provided for sensing the angular position of a body such as a throttle valve. The sensor includes a stator assembly and a rotor assembly adapted to be coupled to the body for rotation relative to the stator assembly. The rotor assembly includes a closed-loop magnetic flux concentrator which defines a controlled electromagnetic cavity and generating means for generating a first magnetic field within the cavity. The stator assembly includes a semiconductor device disposed within the cavity and having an electrical property which is a function of the orientation and strength of a resultant magnetic field. The stator assembly further includes a coil wound about the device for producing a second magnetic field which substantially cancels the effects of the first magnetic field on the device so as to obtain the resultant magnetic field. The electrical current in the coil required to produce the second magnetic field provides an indication of the angular position of the body.

摘要： A digital electric length or angle measuring system includes a scanning unit for scanning a measuring scale and an evaluating circuit for evaluating scanning units generated by a plurality of scanning elements of the scanning unit. The scanning elements are connected to differential amplifiers included in the evaluating circuit. In order to balance faulty signal parameters of the scanning signals of the scanning elements, a balancing circuit is provided which includes bridge circuits. In each case, one diagonal of the bridge circuit is circuited in parallel to the scanning elements in the scanning unit and is connected to the inputs of the differential amplifier of the evaluating arrangement. Furthermore, each of the bridge circuits includes at least one balancing element such as a photosensor.

摘要： A method of zero-level adjustment of a rate sensor wherein the zero-level adjustment in the detection of yawing rate is obtained by subtracting a quantity of drift of an output from the rate sensor during the period of time that the vehicle is stopped or standing still from a subsequent output therefrom in the normal travelling operation of the vehicle. The current state of the vehicle, i.e., whether it is travelling or standing still, is detected by a travel distance sensing device which generates electric pulse signals for a given unit distance travelled by the vehicle; and the sampled outputs from the rate sensor are averaged for the period from immediately after the detection of a standing still state of the vehicle to the moment just before a starting of travel thereof. The thus-obtained averaged value is determined as a current drifting value of the sensor and is subtracted from a current angle of deviation value obtained during normal travel of the vehicle. A substantial improvement in accuracy of zero-level adjustment is thereby attained.

摘要： In a device for continuously monitoring the characteristics of a moving filament, such as the denier of an extended synthetic yarn, by passing the filament through a capacitive sensor to develop an electrical signal representing an absolute measurement of the filament with reference to a prescribed datum, the problem of measurement signal drift arising from contamination of the capacitive sensor is obviated by developing compensating signals to be combined with the filament measurement signal. The compensating signals are digitally formed and stored, thereby eliminating drift in the compensating signals themselves. The compensating signals are developed in an auto-calibration circuit, including an auto-zero circuit and an auto-gain circuit, which receives the measurement signal from the capacitive sensor. While the sensor is vacant, the auto-zero circuit digitally counts clock pulses to generate a digital output, converts the digital output into an analog signal varying with the digital count, detects a prescribed comparison between the analog signal and the input measurement signal, and stops the clock pulse count at a zero compensating value when the comparison is detected. Then, the auto-gain circuit applies an unbalanced drive to the sensor, digitally counts clock pulses to generate a digital output, and varies the measurement signal gain with the digital output. The circuit detects a prescribed comparison between the gain-adjusted measurement signal and a standardized output signal, and stops the clock pulse count at a gain compensating value when the prescribed comparison is detected.
