Patent number: 8597009Abstract: Systems and methods are described for performing film insert molding (FIM) on a 3D shape, such as a traffic light shell or cover. A film is pre-generated for a surface to be covered by the film, and is inserted into a mold. A viscous material is then injected into the mold and the film bonds to the shell as the viscous material cools and hardens. The film includes a material selected to provide one or more of scratch resistance, improved shell hardness, UV protection, corrosion protection etc., and/or may be selected to alter optical characteristics of the shell.Type: GrantFiled: April 22, 2008Date of Patent: December 3, 2013Assignee: GE Lighting Solutions LLCInventors: Patrick Martineau, Eden Dubuc, Christopher L.

Patent number: 7268674Abstract: The inventive dummy load is mounted on the input power cables of a traffic signal while managing the heat load generated by either a resistive and/or capacitive load. Using the inventive dummy load, there is no thermal path back to the light emitting diode (LED) board. The inventive dummy load may be easly installed, removed, or replaced. The dummy load can be retrofit to adapt to a new controller, either by adding to or replacing the dummy load after initial installation or by removing part or all of the dummy load. There is no need to breach the sealed lamp to adjust the dummy load. Thus, field-adjustments can be made. Further, the number of parts required to manufacture lamps for a variety of retrofit applications are reduced, which in turn reduces the cost and complexity of the lamp.Type: GrantFiled: January 26, 2005Date of Patent: September 11, 2007Assignee: GELcore LLCInventors: Christopher L. Bohler, Louis Brunet

Patent number: 6398389Abstract: In an SLM-type display system, a solid state light source can be used to augment a lamp light source in a least two different ways. First, a solid state source can be used to augment deficiencies in a particular spectral region. Typically, lamps are deficient in red, and a red solid state source would be used. However, the same concept applies to augmenting any color region. Multiple solid state sources could be used to augment more than one region. Second, when the SLM system uses a color wheel, a solid state source can be used to eliminate “spoke loss”. Multiple solid state sources can be used for providing different colors during the spokes.Type: GrantFiled: December 1, 2000Date of Patent: June 4, 2002Assignee: Texas Instruments IncorporatedInventors: Christopher L.

Patent number: 5602475Abstract: A single-mode semiconductor laser for optical pumping in H.sup.e and .sup.4 He and high-sensitivity magnetometers based upon these systems. A distributed Bragg reflection (DBR) or distributed feedback (DFB) single mode, preferably InGaAs laser diode (1) which obviates the need for optomechanical arrangements and their inherent instabilities as required by the prior art laser pumped magnetometers. By constructing a DBR or DFB region (28) within the laser diode structure, the laser is forced to operate within a single-mode at a wavelength that is jointly determined by the gain of the laser medium and feedback from the Bragg grating. This wavelength is controllable in one of three ways: (1) temperature control (13) of the laser diode junction and grating, (2) injection current control (12) within the gain region, (3) current control (11) of the Bragg grating region or any combination of the three.Type: GrantFiled: April 4, 1994Date of Patent: February 11, 1997Assignee: Texas Instruments IncorporatedInventor: Christopher L.
