An adjustable armrest for use with an operator's seat on a vehicle includes a pair of pins which project laterally from a side of the seat. A generally rectangular frame has an open side which faces the seat. A pair of gear wheels mounted for rotation on the frame about its central axis. Each gear wheel has another bore which is offset from the central bore and which receives one of the pins. A drive gear drives a belt which rotates the gear wheels to move the drive gears and frame with respect to the pins. A knob is slidably and non-rotatably coupled to an end of a sleeve which, in turn, is fixed to the drive gear. The knob is rotatably and non-slidably coupled to an end of a shaft which is slidable in the sleeve. The other end of the shaft is coupled to a locking pawl. As spring urges the knob, shaft and pawl to a locking position wherein the pawl engages the gear wheels cylinders to prevent their rotation. The knob is movable against the spring to disengage the pawl from the gear wheels.

A system for projecting a hockey puck is provided which includes a hockey puck projector and an associated control system. The hockey puck projector includes a plurality of rollers for supporting the bottom surface of a hockey puck, a wheel for engaging the top surface of the hockey puck, a motor for rotating the wheel, and a ram for moving the hockey puck between the rollers and the rotating wheel. The control system includes servos for rotating the hockey puck projector in three dimensions and a computer control for driving the servos and providing set points which determine the projectory of a projected hockey puck. A hockey puck is projected by the projector when the wheel is rotated and the hockey puck is moved into engagement by the rotating wheel which imparts motion to the hockey puck. The rotating wheel engages the hockey puck above a plurality of rollers which support the puck.
