Abstract: An absolute pressure sensor subassembly includes a top cap bonded to a pressure sensor die and enclosing a reference vacuum. The subassembly is initially held in place within a housing by a vacuum or sublimeable solid adhesive while wire bonds from the subassembly to the housing leads are completed. A self-contained adhesive drop on the inner surface of the housing cover contacts the sensor subassembly when the cover is placed on the housing body and the sensor subassembly is supported by the adhesive drop.

Abstract: A plurality of memory cells arrayed in columns with the memory cells within a column connected between precharged first and second output lines. An input line selects a memory cell within a volume causing the first output line to be pulled to a first voltage when the cell is programmed a true and causing the second output line to be pulled to a first voltage when the cell is programmed a "complement". A pair of cross-coupled transistors connected between the first and second output lines of a column causes the second output line to be maintained at the precharged voltage when programmed a "true" and causes the first output line to be maintained at a precharged voltage when the cell is programmed a "complement".

Abstract: A performance measure of an ATR is made from ancillary target data and the ATR output. A parameter of the ATR is varied to determine the change an ATR performance due to the parameter variation. Separate performance in the form of a quadratic equation models provide performance as a function of parameter and metrics. The performance model is partially differentiated with respect to the parameter. The partial differentiation allows solution for the estimated metric.

A second rolling drum display provides a digital present value of altitude. The elongated dial displays provide greatly expanded display areas and improved readout resolution.

Abstract: Sense amplifier input stage for reading the output of a single array memory having an "unknown" output, a reference "one" output and a reference "zero" output. A first differential amplifier compares the "unknown" output to the reference "one" output, and a second differential amplifier compares the unknown output to a reference zero output. The first and second differential amplifier share the same load Y resistors. Voltage offsets arising in the memory and in the sense amplifier input stage are compensated before the comparisons are made. When the unknown is a one the output has a first polarity and when the unknown is a zero, the output has an opposite polarity.

Abstract: A peak current detecting and non-volatile storage device has a substrate having a hole. Individual magnetic field detecting elements are located on the substrate and are radially displaced from the hole. A conductor extends through the hole. The magnetic field detecting elements are magnetized to a predetermined state. Current carried by the conductor creates a magnetic field around the conductor which alters the predetermined state of magnetization of the magnetic field detecting devices. Various readout techniques may be used to determine the altered state of magnetization which is representative of the magnetic field and may be easily related to the current.

Abstract: A plurality of single transistor memory cells arrayed in columns with the memory cells within a column connected to one or the other of precharged first and second output lines. An input line connected to the gate of the single transistor causes the first output line to be pulled to a first voltage when the cell is programmed a "true" and to be pulled to a second voltage when the cell is programmed a "complement". A pair of cross-coupled transistors connected between the first and second output lines of a column cause the second output line to be maintained at the precharged voltage when programmed a "true" and causes the first output line to be maintained at a precharged voltage when programmed a "complement".

The lower base has an upper end having a central surface portion recessed from a peripheral surface portion for supporting by means of an O ring the peripheral portion of the front surface of the wafer. The clamp rests on a peripheral portion of the back surface of the wafer with the remaining back surface exposed to the backside etching process. A pin and hole arrangement help align the clamp to the base. Holes in the base equalize pressure on both sides of the wafer.
