  • Patent number: 6841950
    Abstract: A method for dimmable control of a multiple output EL lamp driver is disclosed. The multiple output EL lamp driver has a power converter. A plurality of EL lamps are provided wherein one terminal of each EL lamp is coupled to a single common terminal. A plurality of half bridge circuits are provided wherein each circuit has an output impedance. One half bridge circuit is coupled to the single common terminal and each remaining terminal of each EL lamp is coupled to a separate individual half bridge circuit. A logic circuit is coupled to each of the half bridge. An oscillator is coupled to the logic circuit. The method comprises: minimizing the output impedance of the half bridge circuit coupled to the single common terminal to prevent to brightness crosstalk between EL lamps; selecting output impedances of remaining half bridge circuits to produce rounded waveforms across terminals of the EL lamps; and manipulating a drive waveform of one of the plurality of EL lamps to control brightness.

  • Patent number: 6837494
    Abstract: A table and method of playing a combined poker and baccarat-type card game. The method of playing a combined poker and baccarat-type card game comprises dealing 3 cards of both a banker hand and a player hand, with the winning baccarat hand having a higher hand value based on the traditional baccarat scoring system, but without all of the complex baccarat rules for determining if and when a third card is to be dealt. Included is the option of any player to select that the player hand of three cards or the banker hand of three cards or both the player hand and the banker hand will provide a bonus poker hand of one pair, a three-card flush, a three-card straight, three of a kind, a three-card straight flush and a three-card royal flush comprising an Ace and a King and a Queen of any one suit.

  • Patent number: 6832625
    Abstract: An electrically operable valve assembly having an integral pressure regulator provides ease of installation and compact packaging for a water supply control system. The valve assembly is particularly useful for systems that control household water supplies to prevent flooding, but is also useful in other applications such as agricultural and industrial systems where water pressure determined water flow volume must be predicted accurately. The valve may also incorporate a flow meter having a positive flow characteristic permitting determination of very low flow rate flow and the valve may incorporate a manual control. All of the controls and features are integrable within a compact package that occupies essentially the same volume and piping space as a conventional electrically operable valve.

  • Patent number: 6831371
    Abstract: An integrated circuit substrate having embedded wire conductors provides high-density interconnect structure for integrated circuits. Wires are shaped to form a conductive pattern and placed atop a dielectric substrate layer. Additional dielectric is electro-deposited over the wires to form an insulating layer that encapsulates the wires. One or more power planes may be embedded within the substrate and wires within the conductive pattern may be laser-welded to vertical wire stubs previously attached to a power plane. Vias may be formed by mechanically or laser drilling (or plasma or chemical etching) through any power planes and screening a copper paste into the drilled holes to form conductive paths through the holes. Via conductors may then be exposed by a plasma operation that removes dielectric, leaving the ends of the via conductors exposed. Wires within the conductive pattern may then be laser-welded to the via conductor ends.

  • Patent number: 6820667
    Abstract: A dual compartment tire has a primary air compartment and a secondary air compartment that is internal to the primary air compartment. During ordinary travel, the primary air compartment is in contact with the road surface, with the secondary air compartment constituting an integral spare tire in the event of a flattening of the primary air compartment. Each of the primary and secondary air compartments is bounded by an exterior surface. In contrast to prior art dual compartment tires, the exterior surface of the secondary air compartment is relatively thicker than the exterior surface of the primary air compartment.

  • Patent number: 6816032
    Abstract: A laminated low-profile dual filter module for telecommunications devices and method provides both Groupe Spécial Mobile (GSM) and Digital Cellular System (DCS) transmit filters in a small package. The filter module comprises multiple layers of ceramic substrate with metal circuit patterns sandwiched between. Two separate filters are implemented within the layers, with a first filter comprising a first set of layers and the second filter adjoining within a second set of layers. Resonators for each filter are positioned at the opposite sides of the module, in order to avoid coupling between the resonators and ground layers are interspersed for isolation. Capacitors are implemented by a first plate defined by an area on one metal layer with the adjacent layers providing ground planes that form the second plate.
