| 20090032620 | METERING SERVOVALVE AND FUEL INJECTOR FOR AN INTERNAL COMBUSTION ENGINE - A metering servovalve for a fuel injector of an internal combustion engine has an electro-actuator and a fixed valve body, which defines a control chamber communicating with an inlet and with an outlet channel. The outlet channel has at least one calibrated restriction and exits through the lateral surface of an axial stem, on which a sleeve slides, in a substantially fluid-tight manner, to open/close the outlet channel and so vary the pressure in the control chamber. The outlet channel is closed by an end portion of the sleeve that is elastically deformable in a radially outward direction, under the thrust of the fuel pressure, to increase the diameter at which the seal against the valve body is formed, with respect to a non-deformed state, and to generate a radial unbalancing force on the sleeve upon opening when the outlet channel is closed. | 02-05-2009 |
| 20100162992 | FUEL INJECTION SYSTEM WITH HIGH REPEATABILITY AND STABILITY OF OPERATION FOR AN INTERNAL-COMBUSTION ENGINE - The system comprises an injector controlled by commands of a control unit. The injector comprises a dosing servo valve having a control chamber provided with an outlet passage that is opened/closed by an open/close element that is axially movable. The open/close element is carried by an axial guide element that is separate from an anchor of an electromagnet. The open/close element is held in the closing position by a spring acting through an intermediate body. Preferably, the strokes of the open/close element and of the anchor are chosen so as to eliminate, upon closing of the solenoid valve, the rebounds of the open/close element subsequent to the first rebound. The control unit controls an injection comprising a pre-injection and a main injection, via two distinct electrical commands, which are spaced apart by a dwell time such as to occur in an area of reduced variation of the amount of injected fuel; therefore, the stability of operation of the system increases as said dwell time varies. | 07-01-2010 |

| 20080211415 | RESISTIVE BYPASS FOR SERIES LIGHTING CIRCUIT - A resistor bypass circuit for a series lighting circuit includes a plurality of serially connected light sources and a bypass resistor being connected in parallel with at least one of the respective light sources, each respective light source being low wattage and being capable operating on a one hundred percent duty cycle as desired. | 09-04-2008 |
| 20090015167 | DECORATIVE LIGHT DISPLAY - A decorative light display includes a plurality of light source assemblies, each respective light source assembly of the plurality of light source assemblies having a known power requirement and at least one power supply operably coupled to each respective light source assembly of the plurality of light source assemblies for supplying power from an external power source to each respective light source assembly of the plurality of light source assemblies, the at least one power supply providing power to each respective light source assembly, which power satisfies the known power requirement thereof. A method of displaying decorative lighting is further included. | 01-15-2009 |
| 20100096999 | LIMITED FLICKER LIGHT EMITTING DIODE STRING - A limited flicker decorative light-emitting diode (LED) string includes a power plug adapted to connect to an alternating current (AC) power source and supply AC power to the LED string, a first pair of LEDs and a second pair of LEDs, a plurality of LEDs electrically connected in series to form an LED series, and a plurality of rectifying diodes. The plurality of rectifying diodes provides full-wave rectification of the AC power to the LED series and half-wave rectification of the AC power to the first and second pair of LEDs. | 04-22-2010 |
| 20110038158 | MECHANICAL BYPASS LIGHT UNIT - A light unit includes a bulb having a light source with lead wires and a separator, a switch member that includes a support member and a pair of spring terminals, and a socket having two or more conductive terminals and adapted to receive the bulb and the switch member. The switch member is adapted to cause the pair of spring terminals to contact one another to form an electrical short circuit across the pair of conductive terminals and the light source when the bulb is completely or partially removed from the socket. The lead wires form an electrical connection across the conductive terminals and the separator breaks contact between the pair of spring terminals when the bulb is seated in the socket. | 02-17-2011 |
