  • Patent number: 7940530
    Abstract: A circuit board arrangement includes a first printed circuit board having a first edge connector and a second printed circuit board having a second edge connector. The first edge connector includes a plurality of fingers, with each finger having at least one first conductor pad. The second edge connector includes a plurality of openings positioned generally in line with each other and a plurality of second conductor pads. Each opening has a corresponding finger positioned therein. Each second conductor pad is positioned adjacent a corresponding opening and corresponding first conductor pad.
    Type: Grant

  • Patent number: 7848116
    Abstract: A circuit board arrangement includes a first printed circuit board having a first edge connector, and a second printed circuit board having a second edge connector and a plurality of holes positioned in relation to the second edge connector. A pair of circuit board carriers mount the first printed circuit board generally perpendicular to the second printed circuit board. Each circuit board carrier is positioned at an opposite lateral edge of the first printed circuit board. Each circuit board carrier includes a flat base for abutting the second circuit board, and a pair of wings on laterally opposite sides of the base. Each wing includes a snap-in feature for snap engagement with a corresponding hole in the second circuit board. At least one slot guide retains a corresponding lateral edge of the first printed circuit board. A retainer at an end generally opposite the base retains a distal edge of the first printed circuit board.

  • Patent number: 6216072
    Abstract: A vehicle/implement hitch control system is responsive to a wheel slip signal indicative of the slippage of the driven wheels of the vehicle. The control system generates an integrated slip signal using an integration function, generates a proportional slip signal using a proportional function, and generates a combined slip signal as a combination of the integrated slip signal and the proportional slip signal. An operator-controllable slip response adjuster generates slip response signals. A hitch control signal is generated as a function of the slip response signal and the combined slip signal, so that the operator can vary the response of the hitch control signal to the integrated slip signal, to a mixture of the integrated slip signal, and to various multiples of the proportional slip signal only.
