摘要： The present disclosure relates generally to pressure sensors, and more particularly, to methods and apparatus for compensating pressure sensors for stress, temperature and/or other induced offsets and/or errors. In one illustrative embodiment, a pressure sensor may include a pressure sensing die mounted to a substrate of a pressure sensor package. The pressure sensor die may include on-board compensation. In some instances, the on-board compensation may include an on-board heating element and an on-board zener diode trim network, both situated on or in the pressure sensing die. The zener diode trim network may include one or more zener diodes and one or more resistive elements, where the zener diodes can be selectively activated to “trim” the resistive network to compensate for one or more offsets and/or errors of the pressure sensor. The on-board heating element may be configured to heat the pressure sensor assembly to various temperatures so that temperature related offsets and/or errors may be identified, and then compensated for with the zener diode trim network.

摘要： Method and system for a wet/wet differential pressure sensor based on microelectronic packaging process. A top cap with a hole can be attached to a topside of a MEMS-configured pressure sense die with a pressure sensing diaphragm in order to allow sensed media to come in contact with the topside of the pressure sensing diaphragm. An optional constraint with a hole for stress relief can be attached to a backside of the pressure sense die. Adhesive and/or elastomeric seals and/or solder can be utilized to seal the pressure sense die allowing sensed media to come in contact with both sides of the pressure sensing diaphragm without coming into contact with wirebonds and other metallized surfaces. The MEMS-configured pressure sense die can also be bonded to a substrate with standard die attach materials. Such microelectronic packaging processes yield a high performance and cost effective solution thereby providing wet-wet pressure sensing capability.

摘要： A self-diagnostic measurement method to detect microbridge null drift and performance. An ASIC can be designed to include a self-diagnostic feature that automatically occurs at start up or upon command in Normal Operation whereby the temperature compensated microbridge null can be measured in a state of very low thermal energy and allows for the tracking of microbridge null stability versus time. An Airflow Combi-Sensor ASIC (Heimdal) with its strategic partner ZMD can be developed and can be implemented in the form of a self-diagnostic feature that occurs when power is first applied to the ASIC or upon command. When the self-diagnostic is initiated, power is removed and after the electronics have settled, a small power can be applied to the microbridge to measure the bridge null with reduced sensitivity to flow due to self-heating.

摘要： A calibrated, low-profile magnetic sensor and method for forming such a sensor are described herein. Generally, a magnetic sensing device is formed within a housing, wherein the magnetic sensing device comprises at least one magnet. The magnetic sensor includes a compact integrated circuit package such as, for example, a small outline integrated circuit package (SOIC). A magnetic sensing element is generally mounted to the compact integrated circuit package. The magnetic sensing device can be configured to additionally incorporate a printed circuit board (PCB) having a hole formed therein such that the compact integrated circuit package can be surface mounted off-center on the printed circuit board, so that the hole can be located within the printed circuit board to match a shape of the magnet, allowing the magnet to pass through the circuit board adjacent to the SOIC to complete the magnetic circuit. An orifice placed with in the housing permits a tool to be passed through the orifice within the housing to contact the magnet. The magnet can be placed in the optimum position for calibration of the magnetic circuit thereof. The same orifice that is used for calibrating the position of the magnet can also be utilized as an injection port for encapsulating the device using an injection epoxy dispensing process.

摘要： A geartooth sensor utilizes an algorithm for establishing an adaptive threshold for the switch point of the sensor to minimize drift in the point at which the sensor output changes in relation to the target features it is tracking. The algorithm utilizes measured waveform peak and average outputs and applies a separate empirically derived constant to each value to quickly obtain the major portion of the adaptive threshold value from the product of the first constant and the peak output, and to refine the threshold value further with the product of the second constant and the average output.
