Patent number: 8746104Abstract: The present invention provides a gear absolute position sensor assembly (GAPS) that senses the current absolute, position of the shift lever of a manual transmission. The sensor assembly provides data to an associated electronic controller such as an engine control module (ECM) regarding the current position of the shift lever, such as an engaged gear. The sensor assembly preferably comprises at least one Hall effect or other type of magnetic field (proximity) sensors in combination with an application specific integrated circuit (ASIC) which is supplied with data from the sensors, decodes the output of the sensors and provides an output identifying a specific engaged gear or neutral for use by vehicle or engine management electronics. The sensors are mounted proximate the shift linkage at a location where they can sense both rotation and translation.Type: GrantFiled: July 18, 2013Date of Patent: June 10, 2014Assignee: GM Global Technology Operations, LLCInventors: Christopher G. Benson, William L. Cousins, Bradford W. Bur, Kevin O'Connor, Mark Pickhard, Steven R. Stuve

Patent number: 7564330Abstract: A reed switch has a contact surface composed of three layers of metal applied to the contacts of the reed switch. The three layers comprise first a layer of titanium of approximately 15 to 150 micro inches, second a layer of molybdenum of 15 to 150 micro inches, and finally a contact layer of 5 to 20 micro inches of ruthenium, or other platinum group metal or alloy. The layers may be applied by any suitable methods, for example by sputtering.Type: GrantFiled: April 18, 2007Date of Patent: July 21, 2009Assignee: Key Safety Systems, Inc.Inventors: Mark Pickhard, John Wineke, David Lea, Andrew Petraszak, Steve Topel, Tom Lenz

Publication number: 20060186636Abstract: An electronic system that monitors a trailer hitch assembly having a plate hitch with a throat for receiving a kingpin of a trailer and a locking mechanism for locking the kingpin within the throat. The electronic system determines whether the trailer hitch assemblies is properly coupled to the trailer, and comprises a first magnet creating a first magnetic flux, and a first Hall-effect sensor for sensing the position of the kingpin of the trailer relative to the throat of the hitch plate by measuring the first magnetic flux. The system further comprises a control circuit operably coupled with the first Hall-effect sensor in determining whether the first magnetic flux indicates a proper location of the kingpin of the trailer relative to the throat of the hitch plate. The electronic system discriminates between the kingpin and foreign materials, thereby assuring proper locking of the locking mechanism.Type: ApplicationFiled: February 9, 2006Publication date: August 24, 2006Inventors: Randy Schutt, Mark Pickhard
