Abstract: In accordance with the present invention, there is provided a drilling tool replacement apparatus, the apparatus comprising: a drilling tool holder adapted to receive one or more drilling tools; a drilling tool lifter adapted to move a drilling tool between a first position and an elevated orientation; and a transfer apparatus adapted to transfer a drilling tool from the drilling tool holder to the drilling tool lifter.

Abstract: An island wave pool for a water amusement park is presented. A wave generation apparatus is positioned on an island, the island located within a water-filled swimming pool. The water-filled swimming pool is suitable for water recreation activities, including wading, swimming, and wave riding. A beach recreation area bounds the outer perimeter of the pool. The wave generation apparatus on the central island generates single or multiple continuous waves in the water-filled swimming pool. Wave generation apparatuses are presented, including an island-based caisson wave generator and an island-based plow, channel, and reef wave generator.

Abstract: A drilling or bolting unit for selective use with either a vehicle or a panline of a face conveyor associated with a longwall miner or mining machine is disclosed. In one embodiment, the unit comprises a base adapted for engaging the panline and a plurality of receivers. Each receiver may be adapted for receiving one of the pair of forks of the vehicle, such that the unit may be used as either a panline drilling or bolting unit or as a utility drilling or bolting unit with the vehicle apart from the panline. Related methods are also described.

Abstract: A system for testing an integrated circuit device under test (DUT) communicating though synchronous digital signals and through a high speed serialization/de-serialization (serdes) bus includes a serdes interface circuit for communicating with the DUT via the serdes bus and an integrated circuit (IC) tester for communicating with the DUT and with the serdes interface circuit via digital signals. State changes in the digital signals are synchronized to a clock signal within the IC tester. The serdes interface circuit receives instructions from the IC tester via at least one of the digital signals and responds to the instructions by transmitting data to the DUT via the serdes bus using appropriate serdes protocol, by receiving and storing data transmitted by the DUT via the serdes bus, and by thereafter forwarding the stored data to the IC tester via at least one of the digital signals.
