Patent number: 8398282Abstract: A vehicle front lighting assembly, or headlight assembly, that includes one or more variable tint electrowetting elements overlying a portion of the assembly lens surface. The variable tint electrowetting element is configured to operate to a transparent state whereby the hue of light passing therethrough is not changed, and a tinted state where the hue of light passing therethrough is changed. Alternatively, the variable tint electrowetting element is configured to operate to the tinted state and an opaque state where light is blocked from passing through the electrowetting element. The assembly may use light emitting diodes (LED) as an alternative to more conventional light sources.Type: GrantFiled: May 12, 2011Date of Patent: March 19, 2013Assignee: Delphi Technologies, Inc.Inventors: Frederick F.

Publication number: 20120287510Abstract: A transreflective vehicle mirror system configured to be attached to a vehicle. The system includes an interior unit and/or exterior unit, each of which includes various arrangements of a transreflective layer optionally combined with a transparent display layer and/or a variable tint layer. The units can be configured and operated in a variety of ways to provide the same and/or enhanced features/functions normally associated with conventional side view mirrors, rear view mirrors (with or without an integrated information display), fold down visors (with or without a vanity mirror), and graduated tinting commonly found on the upper portion of automobile windshields. The interior unit and exterior unit can operate to a transparent state so that a field of view or direction viewed by the operator is not obstructed as is the case with conventional rear and side view mirrors, and fold-down sun-visors.Type: ApplicationFiled: May 12, 2011Publication date: November 15, 2012Applicant: DELPHI TECHNOLOGIES, INC.Inventors: FREDERICK F.

Publication number: 20120287493Abstract: A system, controller, and method for controlling a light distribution pattern. A light source and an electrowetting lens cooperate to vary a light distribution pattern of light from the light source. An object detector is used by a controller determine the location of an object and operate the electrowetting lens in order to control the light distribution pattern based on the location of the object. The electrowetting lens provides for faster redirecting of light toward an object when compared to mechanical based system. The light source may be an array of light emitting diodes to provide a reliable, energy efficient source of light.Type: ApplicationFiled: May 12, 2011Publication date: November 15, 2012Applicant: DELPHI TECHNOLOGIES, INC.Inventors: FREDERICK F.

Patent number: 8305678Abstract: A dual view display system that includes a display device and a first louver device. The display device is configured to display a first image at a display location to a first person at a first location and display a second image at the display location to a second person at a second location. The first louver device configured to substantially restrict a first field of view of the first image to the first person. The system may also include a second louver device configured to substantially restrict a second field of view of the second image to the second person. Such an arrangement restricts the fields of view so that, for example, a vehicle driver can not lean over and view something intended only for a vehicle passenger, such as a movie.Type: GrantFiled: December 29, 2010Date of Patent: November 6, 2012Assignee: Delphi Technologies, Inc.Inventors: Frederick F.

Publication number: 20120243070Abstract: A display for displaying images that includes a transreflective electrowetting layer operable to a transparent-state where light passes through the transreflective electrowetting layer and a reflective-state where light is reflected by the transreflective electrowetting layer; a non-reflective layer underlying the transreflective electrowetting layer; and an emissive layer proximate to the transreflective electrowetting layer. The display combines light emitting elements such as OLED's with transreflective electrowetting elements to provide a display that can operate in high ambient light conditions without undesirably high power dissipation by the OLED's, and can operate under low ambient light or no ambient light conditions.Type: ApplicationFiled: March 25, 2011Publication date: September 27, 2012Applicant: DELPHI TECHNOLOGIES, INC.Inventors: FREDERICK F.

Publication number: 20120169682Abstract: A display device built on an insulating substrate suitable for processing on both sides that includes a plurality of conductive through-holes through the substrate. One side is reserved for a high-density array of organic light emitting diodes (OLEDs). The OLEDs can be high-density because the electrical connections for the OLEDs are on the other side of the substrate and interconnected via the conductive through-holes. The cathode sides of the OLEDs are interconnected by a light transmitting layer overlaying the cathode side that is electrical conductive. On the side of the substrate opposite the OLEDs is an array of anode contacts configured to form an electrical contact with a driver circuit.Type: ApplicationFiled: December 29, 2010Publication date: July 5, 2012Applicant: DELPHI TECHNOLOGIES, INC.Inventors: FREDERICK F.

Publication number: 20120169684Abstract: A display system for displaying a seamless mosaic of a plurality of images projected by a plurality of projectors by aligning the images projected so the mosaic appears seamless. The display system includes a display surface, a first projector, and a second projector configured to project onto distinct areas that partially overlap. A light detector located adjacent to the display surface detects light projected onto the overlap area. Image signals received by the projectors are adjusted to eliminate the overlap and or balance the brightness of each projected image so the composite image appears to be a seamless mosaic.Type: ApplicationFiled: December 29, 2010Publication date: July 5, 2012Applicant: DELPHI TECHNOLOGIES, INC.Inventors: MICHEL F.
