Abstract: The present invention is related to a stretchable tubular device (1) comprising at least one layer (Lx) of a stretchable polymer, a power supply (2) and a set of electrodes (3a, 3b) connected to said power supply (2). The power supply can supply at least a first level of voltage (V1) to the electrodes so as to modify the natural force (F0) of the stretchable layers to a modified force (F1). The present invention also covers a process for manufacturing such a tubular device and its use as a medical implant.

Abstract: A DC/DC converter comprising a first charge pump circuit including first MOS transistors including first depletion MOS transistors, an oscillating circuit connected to the charge pump circuit only at the gates of some at least of the first MOS transistors, including the first depletion MOS transistors.

Abstract: The invention relates to a tri-surface table tennis table and method of use, the tennis table comprising a configuration achieved placing three regulation tennis table surfaces next to each other to form a symmetrical arrangement, so that two of each surface's vertexes touch another surface's vertex, with each two touching vertexes forming a 120° angle. The invention also comprises a triangular surface that fits in the hole created in the center of the tri-surface configuration to form a smooth surface holding the three tennis table surfaces together, and a trilateral net structure further comprising three pieces of net, each piece of net having an inner end and an outer end, wherein the three inner ends are attached to one another and centered on the tri-surface table tennis table and the outer ends are one hundred twenty degrees apart, running to the three touching vertexes of the three playing surfaces.

Abstract: An electronic assembly is fabricated by tinning a solder to the electrical bonding pads of a printed circuit board, and applying an adhesive, preferably a filled polyurethane adhesive, to the component that is to be bonded to the printed circuit board. The component is contacted to its bonding location on the printed circuit board, and the electrical contact on the component is contacted to the tinned bonding pads. The assembly is heated in a single solder temperature/time reflow cycle to simultaneously cure the adhesive and solder the electrical contacts to the bonding pads.

Abstract: A teaching device assists a child in learning to put on shoes correctly by rewarding the child when the shoes are put on correctly. A telescoping enclosure has a movable upper section with footprints on the upper section. The footprints are shaped to conform to right and left shoes, and additional symbols may be applied to the footprints. The child's shoe will have a shorting bar to cooperate with an electric grid on one of the footprints. As a result, when the shoes are on correctly, the shorting bar will engage the electric grid so a circuit will be completed, and entertainment will be provided in the form of light and/or sound play.
