The lamps voltage, approximately 40 volts, is developed in this lamp by vaporizing zinc iodide instead of mercury. A compromise between voltage and luminous flux is achieved through the choice of the sodium scandium (Na:Sc) molar ratio, between 4.5:1 and 6:1 and a zinc iodide (ZnI2) dose of 2 to 6 micrograms per cubic millimeter that permits the lamp to operate within the North America, European and Japanese automotive color specifications for white light. The voltage in the lamp can be controlled according to the zinc iodide doping level without seriously impacting the visible spectrum otherwise provided by the other known dopants in the lamp.Type: ApplicationFiled: September 12, 2002Publication date: October 9, 2003Inventors: Walter P.

Publication number: 20030189409Abstract: A mercury vapor discharge fluorescent lamp is provided that has a mercury barrier. The mercury barrier is effective to inhibit mercury atoms from absorbing into the glass envelope and amalgamating with sodium atoms in the envelope. The mercury barrier is substantially non-mercury absorptive, both when the lamp is on and when it is off.Type: ApplicationFiled: April 8, 2002Publication date: October 9, 2003Applicant: General Electric CompanyInventors: Curtis E.

Publication number: 20030189411Abstract: A ballast system for use with a fluorescent lamp having two filaments disposed at opposite ends of the lamp. The ballast system has a DC input terminal for connection to a DC voltage source or for receiving a rectified DC signal. The ballast system also includes a capacitor operably connected between the DC input terminal and the lamp and an inductor, wherein the lamp operably connects the capacitor in series with the inductor. The ballast system further includes a first power transistor operably connected to a junction joining the DC input terminal to the capacitor and a second power transistor operably connected to drive the first power transistor. The emitter of the first power transistor and the collector of the second power transistor are operably connected to the inductor such that the two power transistors sense a change in voltage across the inductor and control current from the DC voltage source to the capacitor in response to a change in voltage across the inductor.Type: ApplicationFiled: April 3, 2002Publication date: October 9, 2003Inventor: Sri Sridharan

Publication number: 20030189412Abstract: An improved lighting fixture is disclosed, having a plurality of groups of distinct light-emitting devices, e.g., light-emitting diodes, that can be controlled to produce a beam of light having a wide variety of complex luminous flux spectra, including but not limited to spectra that closely emulate that of any one of a number of conventional light sources, with or without a conventional chemical dye filter. Each group of light-emitting devices is configured to emit light having a distinct luminous flux spectrum. A controller supplies selected amounts of electrical power to two or more groups of the plurality of groups of light-emitting devices, such that the groups cooperate to produce a composite beam of light having a selected luminous flux spectrum. The spectrum can be controlled to have a normalized mean deviation across the visible spectrum, relative to that of a beam of light to be emulated, of less than about 30%.Type: ApplicationFiled: April 8, 2002Publication date: October 9, 2003Inventor: David W.

Publication number: 20030189413Abstract: A brushless motor having a control circuit with a heat detector has a rotor, a stator with two coils and a control circuit. The control circuit has a driver IC connected to the two coils, a Hall element connected to the driver IC, a heat detector connected to driver IC and an AC to DC converter connected to an AC power source. The AC to DC converter provides converted DC power to the driver IC, the coils and the Hall element to make them operate normally. Therefore, the motor can directly use the AC power source by the control circuit. The motor has a function for automatically adjusting rotational speed of the motor by the heat detector to decrease power consumption.Type: ApplicationFiled: April 5, 2002Publication date: October 9, 2003Inventor: Hsin-Mao Hsieh

Publication number: 20030189414Abstract: An edge detector 15 of an ASIC 3 detects a pass timing signal indicating a timing in which slits of a slit plate pass light emitting and receiving elements of a photo interrupter, and the rotation direction of a transfer roller based on phase-A and phase-B signals from an encoder 56. A position counter 16 counts the pass timing signal in accordance with the rotation direction of the transfer roller. When a count comparator 17 detects the agreement of the count value of the position counter 16 with the set value of a stop position setting register 12, a stop position processor 22 counts a delay time, and outputs a stop command signal of an LF motor to a PWM generator 8 in the timing of agreement with the set value of a time setting register 11.Type: ApplicationFiled: March 19, 2003Publication date: October 9, 2003Applicant: Brother Kogyo Kabushiki KaishaInventors: Kazushige Muroi, Masatoshi Kokubo

Publication number: 20030189415Abstract: Pulse variable information is used to control at least obstacle detection and also, optionally, speed of movement of a movable barrier. In one embodiment, pursuant to a learning mode the movable barrier is moved and, while moving the movable barrier, at least one pulse variable that corresponds to movement of the movable barrier at a desired speed is measured and used to determine at least one predetermined threshold that corresponds to a level of excessive force as exerted by the movable barrier. This threshold can then be used during an operating mode to facilitate detection of barrier obstacles.Type: ApplicationFiled: April 8, 2002Publication date: October 9, 2003Applicant: The Chamberlain Group, Inc.Inventor: James Fitzgibbon
