Title: PC add-on board installation apparatus for industrial applications
Inventor: HUNT STEVEN DAVID
IPC: G06F1/00
Filed: 1997-04-11
Granted: 1997-12-11
Abstract: The apparatus includes a movable card guide mechanism for receiving a PC add-on board. The movable card guide mechanism moves vertically to seat the add-on board in, or remove the add-on board from, a bus connector when an external latch is moved inward or outward. The external latch is attached to the movable card guide mechanism by means of an actuator, and the movable card guide mechanism is mounted to the inside top wall of the PC's chassis. Thus, when the actuator moves in one direction, the movable card guide mechanism is moved down, seating the edge connector of an add-on board in a bus connector on the PC's motherboard, and when it moves in the other direction, the movable card guide mechanism is moved up, removing the add-on board from the bus connector.

Title: Brushless DC motor control
Inventor: BOYD JOHN H
IPC: H02P6/18
Filed: 1998-04-03
Granted: 2000-07-11
Abstract: An electrically commutated brushless DC motor primarily for fractional horsepower applications of the type where at any instant one motor winding is un-powered and used to detect back EMF zero-crossings which information is used to initiate winding commutations. The duration of the pulse produced in this winding due to dissipation of stored energy by free-wheel diodes in parallel with the commutation devices after supply of current has been removed from this winding is used to provide a measure of motor current. This allows for simplified commutation device current limiting circuits and is available for control purposes which are a function of motor torque. There is also disclosed a method for maximizing useful power output by reducing the phase angle between the motor current and the back EMF. This is accomplished by introducing a delay in commutating the motor windings beyond the occurrence of each back EMF zero-crossing, with the delay being a function of the time between commutations.
