20110241542 | MAGNETRON - A magnetron includes a cathode and a vacuum envelope in which the cathode extends. The vacuum envelope includes a portion extending radially relative to the axis of the cathode. A pair of electrically conducting support arms for supporting the cathode are in electrical connection with cathode supply terminals. The support arms have free ends connected to the cathode by leads. A wall extends across an area of the radially-extending portion. The wall is positioned along the radially-extending portion nearer to an end of the radially-extending portion that is adjacent to the cathode than to an end that is remote from the cathode and the support arms are mounted in the wall. | 2011-10-06 |
20110241543 | MAGNETRON - A magnetron includes an anode with an anode casing at least partly surrounding the anode. A pair of permanent magnets on each side of the anode define an interaction region and create a magnetic circuit defining a magnetic field through the interaction region. A mass of magnetically permeable material is positioned in a vicinity of the magnetic circuit. The mass is arranged to be slidable over the anode casing. A locking device secures the position of the mass to set the strength of the magnetic field through the interaction region. | 2011-10-06 |
20110241544 | LIGHTING SYSTEM ARRANGED IN VEHICLE DOOR - A lighting system for a motor vehicle | 2011-10-06 |
20110241545 | VEHICLE HEADLIGHT ALERT SYSTEM AND METHOD - A vehicle controller may be configured to detect a headlight condition wherein a headlight is off and an ambient light level is less than a predetermined threshold, and to reduce electrical power supplied to an electrically powered vehicle interior accessory device in response to detecting the headlight condition to inform a driver that the headlight is off. | 2011-10-06 |
20110241546 | RF Screen Assembly for Microwave Powered UV Lamps - An RF screen for microwave powered UV lamp systems is provided. The RF screen is formed of a single sheet of conductive material in which a mesh pattern has been formed. The screen includes a non-traditional mesh pattern including individual openings with 3 or more nodes. The RF screen is generally configured to optimize the balance between light transmission and RF energy leakage desired for the particular application. Generally, it is desired that the RF screen has an open area percentage greater than about 80% while limiting RF energy leakage from the microwave powered lamp system to acceptable levels. | 2011-10-06 |
