    摘要： A mounting device for covering a roof penetration in a roof includes a base having a hub, an outer perimeter structure, an open top, an open bottom, and ribs extending from the hub outward to the outer perimeter structure. An internal reservoir in communication with the open top and the open bottom. At least one of the ribs is formed with a bore for receiving a fastener for fastening the mounting device at the roof penetration.

    摘要： A method includes providing a transformer with primary and current injection windings, a primary switch connected to the primary winding, a parasitic capacitance reflected across the primary switch, a secondary rectifier means, and a current injection circuit including a current injection switch connected to the current injection winding, and a unidirectional current injection switch connected to the current injection winding. The method includes switching on the current injection switch to start a current injection flowing from a controlled voltage source, through the unidirectional current injection switch and further through the current injection winding. The current injection reflects into the primary winding, thereby discharging the parasitic capacitance reflected across the primary switch. The method includes turning on the primary switch with a delay time after the current injection switch turns on and turning off the current injection switch after the current injection reaches zero amplitude.

    摘要： A battery pack including a rectangular prismatic outer housing including a front and a back, opposed sides, a bottom and an open top, and a lid applied to the open top to define a closed outer hold within the outer housing. The battery pack further includes a power switch, a power port, an input/output, and a display all carried in the front of the outer housing. An inner housing is within the outer hold of the outer housing and includes a basin and a lid applied to the basin to define a closed inner hold within the inner housing. A plurality of battery cells are disposed entirely within the inner hold, and the battery cells are electrically coupled to the power port to provide power to the power port.

    摘要： A method for removing an EMV chip from a plastic credit card or debit card and placing the removed EMV chip onto a metal card, includes heating the plastic credit or debit card containing the EMV chip to loosen the EMV chip, the EMV chip being substantially square and planar, the EMV chip having an upward top face, a downward bottom face, and four sides; removing the loosened EMV chip from the plastic credit or debit card; bending the four sides of the EMV chip towards the downward bottom face of the EMV chip; applying an adhesive coating to the bottom face and the bended four sides of the EMV chip; and placing the adhesive coated bottom face and bended four sides of the EMV chip into a holding cavity of the metal card.

    摘要： A quick-release device for securing a gas cylinder in a seat plate includes a pedestal defining a socket for receiving the gas cylinder. The pedestal projects upwardly from an endwall to form a jaw against which the gas cylinder is received when applied to the socket. A clamp is pivoted to the jaw for movement between an open position and a closed position. A flange is formed in the pedestal and has a lower surface for confrontation with the seat plate. A latch is coupled to the pedestal. The latch moves between a first position enabling movement of the clamp between the open and closed positions, and a second position disabling movement of the clamp between the open and closed positions.
