Abstract: A wireless hoist system including a first hoist device having a first motor and a first wireless transceiver and a second hoist device having a second motor and a second wireless transceiver. The wireless hoist system includes a controller in wireless communication with the first wireless transceiver and the second wireless. The controller is configured to receive a user input and determine a first operation parameter and a second operation parameter based on the user input. The controller is also configured to provide, wirelessly, a first control signal indicative of the first operation parameter to the first hoist device and provide, wirelessly, a second control signal indicative of the second operation parameter to the second hoist device. The first hoist device operates based on the first control signal and the second hoist device operates based on the second control signal.

Abstract: A boardlock for holding a socket to a circuit board comprises an integral body including a main beam, a socket retention section adapted to self-retain to the socket, and a circuit board retention section engageable in a hole in the circuit board. The circuit board retention section is substantially flat and, together with at least the main beam, defines a plane. The circuit board retention section includes a pair of spaced apart legs extending in the plane from the main beam to a common remote end defined by a tie bar. The legs are dimensioned to extend beyond an exit of the hole at a far side of the circuit board. Portions of the legs are divergently angled as they extend to a widest dimension of the circuit board retention section. The widest dimension is chosen to be wider than a widest dimension of the hole exit in the circuit board, and to be spaced from the main beam by a distance greater than a thickness of the circuit board at a periphery of the hole exit.
