Abstract: A pointing apparatus and method of operation for an antenna mount provided with a base frame and an antenna mount rotatably coupled together. A first wheel rigidly coupled to one of the base frame and the antenna mount driven by a mechanical linkage with a first drive wheel and a second drive wheel mounted to the base frame or the antenna mount not rigidly coupled to the first wheel. The first drive wheel and the second drive wheel driven against one another in opposite directions; a torque level unbalance applied between the first motor and the second motor operative to rotate the base frame and the antenna mount with respect to one another in a first desired direction.

Abstract: A thermal compensating subreflector tracking assembly for a reflector antenna and methods of use. The subreflector tracking assembly provided with a base, an intermediate support and a subreflector mount. The intermediate support coupled to the base, movable normal to the base and the subreflector mount coupled to the intermediate support, movable orthogonal to the intermediate support. The movement in the Z, Y and or Z-axis enabling electrical performance optimizing reflector antenna beam alignment and/or focus adjustments resulting from asymmetric thermal distortion of the reflector antenna.

Abstract: A motor pack for an electrically driven tool includes at least one electric motor and a linearly displaceable member coupled to the electric motor such that the linearly displaceable member is displaced axially by operation of the at least one electric motor. The motor pack further includes a housing enclosing the electric motor and at least partially enclosing the linearly displaceable member. The housing includes a front plate to which a tool head may be removably coupled. The front plate has an aperture formed therein through which the linearly displaceable element can be coupled to a moveable element in the tool head. The motor pack also includes tool control circuitry enclosed within the housing and electrically coupled to the electric motor to control operation thereof.

Abstract: An electrically powered clamp has a housing, a motor attached to the housing, a ball screw driven by the motor via a belt, and a linkage driven at one end by the ball screw such that the linkage rotates an output shaft attached to the other end of the linkage. The motor and belt drive the ball screw between a fully extended position to rotate the shaft to a clamped position, and a fully retracted position to rotate the shaft to an unclamped position. A built-in computer monitors and controls the clamp. The clamp can also be controlled and monitored by a remote pendant. Indicator lights on the housing and remote pendant convey clamp status information. The clamp is programmable and can memorize the clamped and unclamped positions. The clamp uses velocity and position feedback to determine appropriate drive mode. Torque monitors and timers determine if the clamp becomes stuck.
