    Abstract: A method and device for monitoring the position of a second point relative to a first point. A magnetic field is produced from the first point and received at the second point to produce an output signal therefrom. Preferably, the magnetic field is produced by a transmitter located at the first point and is received by a receiver located at the second point. The position of the first point relative to the second point is then determined by using the output signal. Preferably, the first point and the second point are both freely movable and therefore, both the transmitter and the receiver are mobile. As well, preferably both the first and second points are located on a human body. Finally, preferably, a feedback signal is produced for indicating the determined position of the second point relative to the first point. The determined position of the second point relative to the first point may be compared with a preset reference position such that the feedback signal indicates a discrepancy between the position of the second point relative to the first point and the preset reference position.

    Abstract: Examples of a wave simulator for board sports and other uses are disclosed. An example wave simulator includes means for forming a wave, the means having at least one inclined side wall and a bottom corresponding to a desired wave shape. The wave simulator includes means for flowing water along at least partially along the inclined side wall and bottom of the flume to form a simulated wave. The wave simulator includes means for restraining a board rider in the means for forming a wave. Streamlines of the simulated wave are substantially parallel to a crest line of the simulated wave, and an inclined water flow ends in a downward arc.

    Abstract: An outlet cover for temporarily covering an outlet box with an outlet installed in the outlet box. The box having a plurality of inwardly facing surfaces, a plurality of outside surfaces, and at least two mounting arrangements for securing the outlet thereto. The outlet including at least two elongated tabs for the securing of the outlet to the box wherein the tabs extend on either side of a plug receiver. The outlet cover including a face plate sized to at least substantially cover the plug receiver wherein the face plate has a front surface and an oppositely facing rear surface with a perimeter extending about the front surface. The cover further including a plurality of rearwardly extending friction tabs extending about a portion of the perimeter configured to extending between the outlet and the outlet box to frictionally engage at least one of the inwardly facing surfaces and retain the cover in a mounted position on the box such that the cover remains fixed relative to the box by the frictional engagement and the cover is spaced from the outside surface of the box.
