Abstract: A system for installing a circuit board edge connector into a motherboard connector from the side to accommodate high density card arrangements that obstruct overhead clearance. In one embodiment, the system utilizes an insertion tool which conveys the circuit board across the motherboard and positions it with the pins of both boards aligned. The tool locates the board adjacent the motherboard with the aligned connectors just touching and blocked against withdrawal. The cooperation between ramps and pins associated with the tool and circuit board applies a force, upon the withdrawal of the tool from the motherboard, to engage fully the pins of the circuit board with the pins of the motherboard. The extraction of the circuit board from the motherboard uses the tool in a reverse sequence.

Abstract: A surf wave generator which can repeatedly produce and launch singular waves across the surface of a swimming pool. The waves are produced in the swimming pool by an adjacent water-filled caisson which is coupled into the swimming pool at the base of the pool and caisson. Except for the opening into the pool, the caisson is sealed, and a charge of high-pressure air is vented into the upper portion, forcing the water from the chamber into the swimming pool in a single forceful motion. Through the use of a baffle, the expelled water is directed within the swimming pool to produce a surf wave propagating across the surface of the swimming pool away from the wave-generating caisson. The surf wave may be repeatably generated without synchronization to the previously generated waves. The surf wave generator can also be used in combination with other wave-generating systems to produce a complete repertoire of wave motions.
