20090295290 | METAL LEAD-THROUGH STRUCTURE AND LAMP WITH METAL LEAD-THROUGH - A metal lead-through structure being embedded in an embedding material and operating in a temperature range is suggested. The metal lead-through has a start point and an end point, and comprises elementary sections enclosing an angle between each other. The elementary sections have a length smaller than the length leading to a thermal expansion difference between the metal lead-through and the embedding material developing a break in the embedding material. The elementary sections are connected to and enclose an angle magnitude between each other so that a sum of the thermal expansions thereof taken in a direction determined by a straight line drawn between the start point and the end point of the metal lead-through is smaller than the expansion developing a break in the embedding material. A lamp comprising the metal lead-through structure is also suggested. | 12-03-2009 |

20110048313 | INDICATING THERMAL DOSAGE EXPOSURE OF ELECTRIC LAMPS - A thermal dosage indicator for an electric lamp provides real time indication of time and temperature exposure of the lamp. In one version, a coating on a designated portion of the lamp changes color upon exposure to different combinations of time and temperature. In another version, a semiconductor is mounted on the surface at a designated location on the lamp and the electrical properties of the semi conductor monitored to give an indication of thermal dosage exposure. In another version, a carbon cell of predetermined dimension is mounted on the lamp surface and is monitored at specified intervals to determine dimensional changes from thermal sublimation to give an indication of thermal dosage. | 03-03-2011 |
20110084589 | VIBRATION RESISTANT ELECTRIC INCANDESCENT LAMP AND METHOD FOR REDUCING VIBRATION - An electric incandescent lamp comprising at least one incandescent filament is provided. The incandescent filament is arranged inside a translucent envelope. The lamp also comprises support wires that protrude out of a stem. The filament has end portions, and each end portion is fixed to a corresponding support wire at a junction point. At least one of the support wires comprises at least one narrowed portion for reducing vibration. The narrowed portions are disposed between the junction point and the stem. In an exemplary embodiment of another aspect of this invention, at least one of the support wires has a second section overhanging beyond the junction point of the end portion of the filament. The at least one narrowed portion for reducing vibration is comprised by the second section. A method for reducing vibration is also disclosed. This method comprises a step of forming at least one narrowed portion in at least one of the support wires. | 04-14-2011 |

20080273741 | Electronic Watermark Embedding Method, Electronic Watermark Detecting Method, Electronic Watermark Detecting Apparatus and Program - An electronic image into which an electronic watermark is to be embedded is divided into a plurality of image regions spatially, and pixels each having a property of being difficult to visually recognize a variation in a pixel value are extracted as adaptive pixels from each of the plurality of image regions. A variation between the pixel values of the adaptive pixels in one of the plurality of image regions and those of the adaptive pixels in an adjacent one of the plurality of image regions is produced, and the pixel values of the adaptive pixels of the plurality of image regions are varied in a time direction according to the value of an embedded bit set of the electronic watermark. An electronic-watermark-embedded image is then generated by making the variation in the pixel values of the adaptive pixels vary step by step at a boundary between the two of the plurality of image regions and/or in the time direction so that the variation makes a slow transition. | 11-06-2008 |
