Abstract: The invention consists of a blade for a hockey stick, comprising: a blade portion, with a forehand side and a backhand side and a loop extending from the one or both sides of the blade portion, with the loop dimensioned to enclose a hockey puck.

Abstract: A suspension system supports a seat with respect to a base mounted on a frame of a vehicle. The system includes a hydraulic actuator coupled between the seat and the base. A single accelerometer is attached to the base and generates a base acceleration signal in response to motion of the base. A control unit actively controls the hydraulic actuator as a function of the base acceleration signal. The control unit generates a base velocity signal by integrating the base acceleration signal, generates a seat position signal representing a position of the seat relative to the base, generates a seat position error signal representing a difference between a desired position and the seat position signal, and generates a command signal as a function of the velocity signal and of the position error signal. The control unit controls the actuator by applying the command signal thereto.

Abstract: An aperture is provided for metal parts using conventional laser cutting techniques and equipment. The aperture has a generally eye shaped periphery. The eye shape allows thread forming fasteners to engage a portion of the aperture wall while a portion of the wall does not contact the fastener i.e. at the corners of the eye. Because the aperture walls do not have surface contact around the entire circumference of the fastener the frictional resistance and thus the driving torque required for driving thread forming fasteners is reduced significantly. The particular shape described provides an optimum compromise between the need to reduce driving force and the need to provide sufficient surface contact to maintain firm engagement of the fastener in the aperture.

Abstract: An armrest adjustment mechanism supports an armrest unit with respect to a vehicle seat. The mechanism includes a plate fixed to the seat. The fixed plate has a pair of projecting pins and a plate slot extending between the pins. A frame is movably mounted adjacent to the plate and attached to the armrest unit. The frame has a bore extending therethrough and a pair of frame slots which slidably receive the pins. A bolt has a head which non-rotatably engages the plate and which is slidable in the plate slot. The bolt has a threaded shaft which extends through the bore in the plate. A knob is rotatably and threadably mounted on the end of the shaft. A hollow cylindrical bushing is mounted on the shaft between the knob and the frame. The knob can be rotated to clamp the frame with respect to the plate, or loosened to allow the frame to be moved with respect to the plate.
