Patent number: 11509867Abstract: A method for determining a structural image of a window of a motor vehicle with the aid of a camera, the window separating the camera from surroundings of the motor vehicle. The method includes a highlighting of image structures present in the structural image with the aid of an illumination of the window, the image structures being suitable for ascertaining a visual impairment of a view of the camera through the window. The illumination is configured in such a way that it is not detected by a driver. A device for implementing the method is also provided.Type: GrantFiled: September 2, 2020Date of Patent: November 22, 2022Assignee: Robert Bosch GmbHInventors: Mihály Dezsõ Baki, Karoly Varga-Umbrich

Patent number: 8466609Abstract: An electrodeless or induction ceramic HID lamp includes a ceramic arc body having a generally spheroidal portion enclosing a discharge chamber and an induction coil received around a perimeter portion of the spheroidal portion. At least one leg extends from the spheroidal portion of the arc body. A mounting structure connects the arc body to the surrounding lamp assembly. In one arrangement, a mounting tube is received over at least a portion of the leg, and may further include a light transmissive shroud that also abuts with the induction coil to precisely locate the arc body relative to the coil. In another arrangement, first and second mounting members extend from spaced locations of the arc body, either as pins or legs extending from the spheroidal portion, or radially extending legs from an equatorial portion of the arc body.Type: GrantFiled: October 30, 2009Date of Patent: June 18, 2013Assignee: General Electric CompanyInventors: Joshua Ian Rintamaki, Andrew Lawrence Podevels, Jianwu Li, Paul M.

Patent number: 8356918Abstract: A light distribution assembly includes an electrodeless HID light source providing emitted light along substantially first and second hemispherical zones. A first optical element redirects a portion of light from the first hemispherical zone into a first desired direction in the second hemispherical zone. A second optical element redirects at least a portion of light within the second hemispherical zone. Other optical elements may be added to tailor the light distribution. Various combinations of these components may be used to create the desired illumination pattern.Type: GrantFiled: October 30, 2009Date of Patent: January 22, 2013Assignee: General Electric CompanyInventors: Gary Robert Allen, Viktor Karoly Varga, David C.

Patent number: 7460379Abstract: An ignition circuit and method, as may be used for igniting a gas discharge lamp, are provided. The circuit includes a voltage multiplier circuit connected to receive a signal corresponding to a DC bus voltage level from a rectifier circuit. The voltage multiplier circuit includes first and second voltage storing circuits configured to each respectively store a voltage level corresponding to a first multiple of the DC bus voltage level (e.g., at least twice the DC bus voltage level). The voltage multiplier circuit further includes a peak voltage holding circuit connected to the first and second voltage storing circuits to accumulate a voltage level corresponding to a second multiple of the DC bus voltage level (e.g., at least four times the DC bus voltage level).Type: GrantFiled: September 5, 2006Date of Patent: December 2, 2008Assignee: General Electric CompanyInventors: Xiaoli Yao, Rajendra Kumar Pokharna, Viktor Karoly Varga, Chao Yang, Yingqi Zhang

Patent number: 7456583Abstract: A circuit such as may be used for igniting and operating a gas discharge lamp is provided. The circuit includes a resonant circuit connected to receive a variable voltage output signal from an inverter. The resonant circuit includes a first circuit stage and a second circuit stage. The second circuit stage includes a resonant tank circuit configured to generate a resonant output voltage when a switching frequency of the inverter matches a resonant frequency of the resonant circuit. The first circuit stage includes at least one current-suppressing element for reducing an effect of a resonant current that flows in the resonant circuit on a switching current that flows in the inverter.Type: GrantFiled: September 5, 2006Date of Patent: November 25, 2008Assignee: General Electric CompanyInventors: Xiaoli Yao, Rajendra Kumar Pokharna, Viktor Karoly Varga, Chao Yang, Yingqi Zhang

Patent number: 5939429Abstract: Hemorrhagic shock and in other conditions associated with excessive vasoconstriction, such as hypertension, peripheral vascular disease, cirrhosis of the liver, or certain forms of angina pectoris can be treated by using agonists of CB1 receptors as well as other cannabinoid receptors. In addition, it has been determined that in septic shock and cirrhosis of the liver when hypotension is due to activation of macrophages by bacterial endotoxin, the use of a drug that selectively blocks CB1 receptors or other cannabinoid receptors may be of therapeutic value by preventing or attenuating the endotoxin-induced hypotension.Type: GrantFiled: September 29, 1998Date of Patent: August 17, 1999Assignee: Virginia Commonwealth UniversityInventors: George Kunos, Karoly Varga, Jens Wagner, Earl F.
