  • Patent number: 10446347
    Abstract: A reed for a reed switch and a reed switch are provided. The reed may include a first portion having a first thickness and a first length, a second portion having a second thickness and a second length, and a hinged portion disposed between the first portion and the second portion, the hinged portion having a third thickness and a third length, wherein the third length is less than 150% of the first thickness and the third thickness is less than each of the first thickness and the second thickness. The reed switch may include the reed disposed in an insulating housing with a reed deformer to deform the reed.

  • Patent number: 8746104
    Abstract: 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.

  • Patent number: 7564330
    Abstract: 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.

  • Publication number: 20060186636
    Abstract: 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.
