  • Patent number: 5712765
    Abstract: An electronics module, such as those used in vehicles, comprises a cuboid housing box which is open on one side, a cover with connection plugs to cover the open side of the housing box, and at least one printed circuit board within the housing box and attached to the printed circuit board. Power components producing relatively significant heat are installed on the printed circuit board and in contact with cooling flanges integral with the cover. To facilitate soldering, the cover does not extend along the soldering side of the printed circuit board.

  • Patent number: 4660430
    Abstract: A combination gear-selector, sensor device for use with vehicle transmissions having a plurality of gear positions and certain special gear functions and being controlled by an electronic circuit includes a shift lever having a first, square magnet which, when moved over distinct gear position sensors, indicates selection of a certain gear. A rod coaxially disposed within the shift lever has a second, rectangular magnet, displaced to one side of the first magnet, which when vertically moved over a first function sensor, indicates selection of that function which can be to skip a gear. A coaxial tube surrounds the rod member within the shift lever and has a third, rectangular magnet, displaced to an opposite side of the first magnet, which can be moved over a second function sensor to indicate selection of a second special function.
