摘要： A circuit board has an arcuate array of conductor segments each subject to a digital waveform differing in phase for the various segments, and a concentric pickup conductor. A rotary encoder disk has a conductive pattern which sums and couples the waveforms from selected segments, depending on rotary position, to the pickup conductor. A synchronous phase detector generates a phase signal from the summed waveforms and the zero crossing of the phase signal is detected. A counter develops count signals used to generate the digital waveforms. The count signals are input to a latch which is clocked at the zero crossing point to latch the count value which is a digital measure of the encoder angle.

摘要： A high frequency AC probe signal is applied to one coil of a stepper motor to induce a signal on the other coil. The induced signal varies in amplitude according to rotor position. The stepper motor is driven by a microprocessor in microsteps. The position of a mechanical stop is determined by monitoring the induced signal while driving the rotor to the stop. When the induced signal no longer changes in amplitude the number of the last microstep yielding movement is recorded as the rotor position corresponding to the stop position. Also by measuring the induced signal at each microstep over a whole rotor rotation and the signal when the rotor stops, a more precise value of the stop position is determined by interpolation. Alternatively, the flip back position of the gauge and thus the stop position is determined on the basis of the induced signal.

The count signals are input to a latch which is clocked at the zero crossing point to latch the count value which is a digital measure of the encoder angle. Two encoders mounted on orthogonal horizontal axes are used as an accelerometer or attitude sensor. Each disk is eccentrically weighted to seek a position vertically below the axis to serve as an attitude sensor when the unit is stationary. When the unit is subject to horizontal acceleration the disks rotate from the vertical position to render acceleration readings.

摘要： A rotary gauge driven by a stepper motor has a stop near the zero point of the gauge graphics. A factory calibration procedure rotates the gauge field in reverse direction to move the gauge pointer against the stop and continues field rotation until the rotor becomes unstable and flips back in the forward direction, and then moved to a rotor rest position. The angle of flip back, the rest position and the number of steps to the zero position are stored in non-volatile memory. In the vehicle, when the ignition is off, the microprocessor or the stepper motor wakes periodically and exercises the gauge, using the stored values to reset the gauge to the stable position. When ignition is turned on, the microprocessor moves the gauge directly to the zero position.

摘要： The maximum full level is determined in a fuel tank of undetermined size using a fuel level sender referenced to the tank bottom. A minimum full value is selected for a given type of tank and when the sender signal goes below a percentage of that value and subsequently goes above the minimum full value, a fueling event is recognized and the current fuel sender value is adopted as the maximum full value. Where a heavily filtered signal is used to minimize the effects of fuel slosh, the maximum full value is subject to increasing to higher values occurring during a short period after fueling to allow recovery of the filtered signal. An empty value is calibrated before the vehicle is initially fueled. A maximum empty level is initially set and if a lower level is measured when the ignition is turned on, the lower level is set as the empty value. This calibration is terminated when the tank is fueled above the minimum full value.

摘要： An IC driver mounted on a LCD display package contains a sensor for determining temperature of the LCD cell, and a digital value of the temperature is serially transmitted to a remote microprocessor which determines compensated voltage and sends voltage command data back to the IC driver which produces a drive voltage by a charge pump. A digital code on the LCD cell identifies cell response characteristics and the code is used by the microprocessor to calculate the desired voltage. A ROM in the IC driver stores many bit-mapped images which are selected by the microprocessor for display.

摘要： Two or more communication modules are coupled by a one wire transmission line. A feed module impresses dc power and a sine wave carrier signal on the line. Each module generates a square wave signal synchronous with the carrier, each period of the signal representing one data bit. Data is written onto the line by a module by attenuating the carrier wave for selected bits and read by another module by sampling the bits and detecting those which are attenuated. Address and message data is transmitted in packets of n bits, the first bit always being an attenuated bit. Addressing is accomplished by generating a sequence of n unattenuated bits and then writing packets of address data. An address is valid when it matches a stored address in a module and that module is then activated to read or write. Multiple addressing modules can be used with a priority technique which reserves a priority code location at the beginning of an address string and compares code bits of a sending module with carrier bits, and aborts the address write when the carrier has an attenuated priority bit and the sending module is attempting to send an unattenuated bit.

摘要： An elastomeric connector couples the terminal pads of an LCD with corresponding terminal pads of a printed wiring board (PWB). Conductive elements in the connector are subject to skewing at such an angle that the LCD must be adjusted relative to the PWB to attain pad alignment. Sense pads on the terminal strips are coupled to contact pads and are arranged so that a continuity test on substantially opposed contact pads will verify pad alignment. In one embodiment, one sense pad is narrower than the terminal pads so that even marginal continuity will assure proper alignment of the terminal pads. In another embodiment, a pair of sense pads on either one of the LCD and the PWB is bracketed by a pair of spaced pads on the other such that continuity is evidence of non-alignment.

摘要： A voltage regulator circuit having a series device external to an integrated circuit voltage regulator. The external series device provides a voltage drop prior to the voltage being input to the voltage regulator during high power applications. Depending on the power level, low or high, one of two transistors will be activated. For low power applications, a transistor attached directly to the input voltage is active and the external series device is bypassed. For high power applications, the external series device provides a voltage drop prior to the input voltage reaching the second transistor thereby lowering the power to be dissipated by the integrated circuit.
