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： 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 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.

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. 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： 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 circuit apparatus for providing increased apparent resolution in digital signal processing systems includes a comparison circuit receiving an N bit digital input signal and the N most significant bits of an N+M bit output signal. The comparison circuit compares the two signals and provides a control output in response to the comparison. An N+M bit counter increases or decreases a count value which is the output signal in response to the comparison, whereby the output signal has an apparent resolution 2.sup.M better than the resolution of the input signal.

摘要： A nonvolatile memory has a linear array of memory cells to serially store counts by setting the cells one by one in correspondence with input pulses and when the array is full by resetting the cells one by one for successive pulses. When all the cells are reset a conventional binary counter is incremented and the serial count is repeated for further inputs. This procedure minimizes the erase/write sequences required to count a series of pulses. A shift register having a stage corresponding to each memory cell is used to read out the data from the linear array. Data is loaded from the array into the shift register and shifted out in a serial pulse train to a binary counter.
