20110317394 | Article-Display Stage - The present invention is an article-display stage of the type including a horizontal article-surface for display of an thereon, a backwall, and means to illuminate the article. The inventive article-display stage includes a top and bottom compartments. The top compartment includes a translucent horizontal wall having a front end, the article-support surface and a bottom surface extending rearwardly from the front end to the backwall which is translucent and has front and rear surfaces. The bottom compartment includes an angular wall that extends downwardly from the horizontal-wall front end and has a reflective surface facing the bottom surface of the horizontal wall. A light source behind the compartments provides dual back-and-bottom illumination of the article by directing light both at the rear surface for diffused back-light illumination through the backwall and at the reflective surface for diffused reflected up-light illumination through the horizontal wall. | 12-29-2011 |

20120271378 | METHOD AND APPARATUS FOR PROVIDING COMPLEX TISSUE STIMULATION PATTERNS - The invention relates to a stimulation device for creating complex or multi-purpose tissue stimulation. Many typical stimulation devices suffer from deficiencies in providing complex stimulation patterns. Using a circuitry operable or programmable to repeat and skip stimulation settings, a complex stimulation set may be created. The repeating and skipping functionality may be implemented in hardware or software. In this manner, complex stimulations may be derived from simple circuitries. Furthermore, these stimulations may be used to treat pain, stimulate bone growth, and control motor disorders, among others. | 10-25-2012 |

20080308838 | Power switching transistors - In an embodiment, a integrated semiconductor device includes a first Vertical Junction Field Effect Transistor (VJFET) having a source, and a gate disposed on each side of the first VJFET source, and a second VJFET transistor having a source, and a gate disposed on each side of the second VJFET source. At least one gate of the first VJFET is separated from at least one gate of the second VJFET by a channel. The integrated semiconductor device also includes a Junction Barrier Schottky (JBS) diode positioned between the first and second VJFETs. The JBS diode comprises a metal contact that forms a rectifying contact to the channel and a non-rectifying contact to at least one gate of the first and second VJFETs, and the metal contact is an anode of the JBS diode. A first electrical connection ties the gates of the first VJFET, the gates of the second VJFET, and the anode of the JBS diode to a common gate electrode and a second electrical connection ties the source of the first VJFET and the source of the second VJFET to a common source electrode. | 12-18-2008 |
