    Abstract: An attachment device for attaching office products or equipment to a panel wall that includes generally two elements: a locking member and at least one, and generally two, prong members. The locking member includes a base. Extended outward from the front face of the base is a key member for interaction with a keyhole on an office supply product. The key includes a stem portion and a knob portion and the stem portion is truncated so that the vertical dimension is smaller than the horizontal dimension. The key is inserted into the circular opening of a keyhole on an office supply product, is slid up into the slot portion of the keyhole and is then rotated 90° thereby locking the attachment device to the office product. The pins can be inserted into a panel wall thereby removeably attaching the office supply product to the panel wall.

    Abstract: A three-phase resonant cyclo-converter comprising a power control module, wherein the power control module is arranged to develop a plurality of repeating switching periods within a cycle, the power control module further arranged to: control the length of a first switching period in the cycle to adjust the power flow, and control the relative length of two or more further switching periods in the cycle to adjust the power factor, wherein the relative length is controlled based on a cross-product of voltage and current values associated with the further switching periods.
