Patent number: 8375778Abstract: An engine control module having an environmentally-sealed housing includes a housing-mounted air pressure sensor for providing a reliable measure of atmospheric air pressure to a control circuit mounted within the housing. The sensor is mounted on an inboard face of the housing, and includes a sensor element, a body portion and a riser portion. The sensor element is mounted in the body portion, and the riser portion protrudes through an opening in the housing to couple the sensor element to atmospheric pressure outside the housing. The body portion is sealingly secured to the inboard face of the housing, and a set of conductor pins molded into the body portion extend inward to engage a circuit board enclosed by the housing, and thereby directly couple the sensor element to the ECM's control circuit. The top of the riser portion is capped by a splash-proof lid to prevent water intrusion.Type: GrantFiled: February 22, 2010Date of Patent: February 19, 2013Assignee: Delphi Technologies, Inc.Inventors: Hamid R. Borzabadi, Ronald D. Wilcox, Philip D. Kuznia, Timothy A. Vas, Lewis H. Little, David G. Miller

Patent number: 7497124Abstract: A dual pressure sensor apparatus configured for attachment to a manifold includes a molded plastic housing with a body portion featuring an upper cavity, a measurement port, and a lower cavity closed by the manifold. First and second pressure sensor modules are mounted in first and second wells formed in the upper cavity, and electrically coupled to a set of leadframe terminals disposed in the upper cavity. An opening in the first well couples the first pressure sensor module to the measurement port, and an opening in the second well couples the second pressure sensor module to the lower cavity. The measurement port sealingly extends through an opening in the manifold so that the first pressure sensor module measures pressure in the manifold, and the body portion walls bounding the lower cavity are notched so that the second pressure sensor module measures atmospheric or barometric pressure outside the manifold.Type: GrantFiled: April 20, 2007Date of Patent: March 3, 2009Assignee: Delphi Technologies, Inc.Inventors: Philip D. Kuznia, Timothy A. Vas, Derek A. Delrymple

Patent number: 7421773Abstract: Silicon-based high pressure sensor modules are manufactured in an array arrangement, incorporating a low temperature cofired ceramic (LTCC) substrate. The LTCC substrate can withstand high pressures. Bossed containers filled with oil are mounted on the substrate in an array. These bossed containers house the sensor cells which are composed of a sensor handle wafer and a diaphragm. The top surface of these bossed containers are flexible and deflect under pressure. By controlling the surface area and the thickness of the top surface, the pressure sensors can be configured to measure a wide range of pressures. The oil transfers pressure from the bossed container to the diaphragm of the sensor cell while protecting the sensor cell from high pressures and harsh media.Type: GrantFiled: April 27, 2007Date of Patent: September 9, 2008Assignee: Delphi Technologies, Inc.Inventors: Timothy A. Vas, Timothy M. Betzner, Stephen P. Long
