摘要： An advanced thick film (ATF) pressure transducer can be produced from an advanced thick film stack on a metallic substrate. The metallic substrate has a flexible metallic diaphragm that flexes when there is a pressure differential across its top and bottom surfaces. The conductive and dielectric layers of the ATF stack are patterned into wire networks and bond pads. A strain sensor can be attached to bond pads or can be formed as part of an ATF layer. Flexure of the diaphragm stresses the strain sensor to produce an output proportional to the pressure differential. The ATF pressure transducer can be packaged into a housing that provides easy deployment and electrical interconnectivity.

摘要： A MEMS flow sensor has a flow channel that avoids wire bond pads and ancillary circuit elements. A fluid can move from the bottom of the sensor substrate, though an inlet hole, over a sensing element on the top of the substrate, and then through an outlet hole. The inlet hole and the outlet hole can pass from the substrate top to the substrate bottom. A top cap can be fixed to the top of the substrate such that it covers the sensing element, the inlet hole, and the outlet hole. The top cap constrains the flow channel and keeps fluid, either gaseous or liquid, from exiting the channel and contacting the wire bond pads or ancillary circuit elements.

摘要： A Hall-effect sensor apparatus, system and method. In general, a substrate having a surface can be provided. A plurality of Hall-effect sensing elements can then be configured upon the substrate, such that the centerline of a sensing plane associated with the plurality of Hall-effect sensing elements is located towards the surface of substrate, which results in a reduction of the distance between the centerline of the plane of the plurality of Hall-effect sensing elements and an axis of rotation of an associated bias magnet, thereby optimizing the location of the plurality of Hall-effect sensing elements and minimizing sensitivity to misposition and an increase in sensing accuracy.

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 sensor includes one or more sensor transducers coupled with a signal conditioning IC incorporating signal conditioning circuitry and memory devoted to storing end-user downloadable coefficients. In a preferred embodiment, the IC is an ASIC and the end-user downloadable coefficients are pre-selected by the end-user based on its needs, and the coefficients are pre-stored in the ASIC when the sensor is calibrated. This results in a more cost-effective and space-efficient sensor device with improved functionality over that available in the prior art.

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.
