Particular Waveform Grid Excitation Patents (Class 363/119)
  • Patent number: 11070243
    Abstract: A switching network and associated method for operating within a transceiver are disclosed. The switching network has a timing control circuit that offsets the time at which a through switch and a shunt switch transition between on and off states. The output of the timing control circuit is an inverted and delayed version of a control signal applied to the input of the timing control circuit. Controlling the timing of the shunt switch provides a means to safely discharge any accumulated charge within the capacitance Cgs between the gate and source of transistors included within the through switch.

  • Patent number: 8801285
    Abstract: An improved bulkbag and method of making same, of the type having four sidewalls, a floor and top portion, all portions stitched together to define the enclosure for the bulk bag housing material. The bag comprises a plurality of four wall panels, which each panel having a first and second vertical edge for sewing into the next adjacent panel along each edge. Prior to sewing the panels together, to each upper edge of each panel there is provided a first and second leg of a lifting loop, so that each loop spans from the first edge to the second edge of each panel. The panels are then sewn together along their edges, and there is defined the bulk bag, with the ends of each of the four lifting loops terminating at the stitch line between panels, which define the middle of each sidewall of the bag. There would then be provided a reinforcement ring at each point where a pair of legs of lifting loops are stitched to strengthen the attachment point.

  • Patent number: 7967508
    Abstract: The present invention is directed to an apparatus for collecting fallen leaves or other objects. According to various embodiments, the apparatus comprises a mesh, central collection section for lying flat on the ground such that objects may be accumulated onto an upper side of an interior portion of the central collection section. The apparatus also includes an enclosure system connected to the central collection section such that an operator can enclose a peripheral portion of the central collection section around the interior portion. In that way, the objects accumulated onto the central collection section can be easily transported and subsequently emptied. The apparatus may also comprise a plurality of stiffeners connected to a lower side of the peripheral portion of the central collection section. The stiffeners may extend inward from an outer edge of the central collection apparatus and may be made of plastic.
