Patent number: 9915578Abstract: There is disclosed a high temperature pressure sensing system which includes a SOI, silicon carbide, or gallium nitride Wheatstone bridge including piezoresistors. The bridge provides an output which is applied to an analog to digital converter also fabricated using SOI, silicon carbide, or gallium nitride materials. The output of the analog to digital converter is applied to microprocessor, which microprocessor processes the data or output of the bridge to produce a digital output indicative of bridge value. The microprocessor also receives an output from another analog to digital converter indicative of the temperature of the bridge as monitored by a span resistor coupled to the bridge. The microprocessor has a separate memory coupled thereto which is also fabricated from SOI, silicon carbide, or gallium nitride materials and which memory stores various data indicative of the microprocessor also enabling the microprocessor test and system test to be performed.Type: GrantFiled: July 6, 2015Date of Patent: March 13, 2018Assignee: Kulite Semiconductor Products, Inc.Inventors: Anthony D.

Patent number: 9739677Abstract: Exemplary embodiments of the present invention provide a differential pressure transducer that comprises first and second diaphragms of different configurations, i.e., different diameters and/or thicknesses. The pressure transducer provides more versatility over prior art designs as the diaphragms can be of different configurations yet still maintain substantially similar back pressures. Therefore, the errors commonly associated with back pressures are eliminated because the back pressures from the diaphragms ultimately cancel out in the sensor's differential pressure measurement.Type: GrantFiled: April 10, 2015Date of Patent: August 22, 2017Assignee: Kulite Semiconductor Products, Inc.Inventors: Anthony D. Kurtz, Lou DeRosa, Robert Gardner

Patent number: 9470597Abstract: A wireless interface system that interfaces with any one of a plurality of transducers of different types, such as pressure sensors, temperature sensors, and current probes. The transducers employ identical connectors with a common connecting scheme. In this manner, any transducer can be connected to a wireless interface which has the same input connection scheme. When the wireless interface is connected to the transducer, a rechargeable battery, which is associated with the wireless interface, is activated. The wireless interface then determines the type of transducer being utilized and provides sufficient circuitry as well as determining the requirements of the connected transducer. In this manner, the wireless interface, besides recognizing and determining the type of transducer, can determine the range of the sensor and can provide specific circuitry to be activated to supply power and to read data from the sensor via common output pins.Type: GrantFiled: April 18, 2012Date of Patent: October 18, 2016Assignee: Kulite Semiconductor Products, Inc.Inventors: Anthony D.
