Publication number: 20240134252Abstract: A camera includes a camera housing and an objective carrier assembly having a carrier where a camera objective and a camera sensor are mounted. A method for manufacturing the camera includes aligning the objective carrier assembly in relation to a first housing part of the camera housing. The method includes mounting the objective carrier assembly over the first housing part in an aligned position. The method includes mounting a second housing part on the first housing part.Type: ApplicationFiled: October 20, 2023Publication date: April 25, 2024Inventors: Mario Angel Sahagun, Daniel K.

Publication number: 20230364597Abstract: Improved photocatalysis is provided for chemical reactions involving hydrogen in two component plasmon-catalyst nanoparticles. The main idea of this work is to configure the optical illumination of the nano-articles to suppress formation of an undesirable hydride phase in the nanoparticles. This idea is broadly applicable to any chemical reaction involving hydrogen. Specific examples considered experimentally in this work are acetylene hydrogenation to produce ethylene, carbon dioxide reduction and ammonia synthesis.Type: ApplicationFiled: May 11, 2023Publication date: November 16, 2023Inventors: Jennifer A. Dionne, Alan Dai, Briley Bourgeois, Daniel K. Angell, Dayne F. Swearer, Lin Yuan

Publication number: 20220268704Abstract: Improved stimulated Raman spectroscopy is provided by replacing the Stokes (or anti-Stokes) optical source with a localized electromagnetic emitter that is excited with a non-electromagnetic excitation. Such a localized emitter can be an efficient Stokes (or anti-Stokes) source for stimulated Raman spectroscopy, and can also provide deep sub-wavelength spatial resolution. In a preferred embodiment, an electron beam from an electron microscope is used to excite the localized emitter. This provides combined Raman imaging and electron microscopy that has the two imaging modalities inherently registered with each other.Type: ApplicationFiled: July 24, 2020Publication date: August 25, 2022Inventors: Jennifer A. Dionne, Amr Ahmed Essawi Saleh, Daniel K. Angell

Patent number: 8455835Abstract: A radiation detection system for detecting the presence and location of a radiation source includes an optical fiber bundle having fibers of different lengths, a radiation sensitive material, a stimulating source and an optical detector. The stimulating source stimulates the radiation sensitive material and the radiation sensitive material releases a light output, while the light output provides a readout signal for each fiber corresponding in intensity to the radiation received from the radiation source. The optical detector receives the readout signal such that the variations in intensity of the readout signals along the length of the bundle determine the presence and general location of the radiation source.Type: GrantFiled: August 31, 2011Date of Patent: June 4, 2013Inventors: Daniel K. Angell, Thomas K. Hunt

Patent number: 7365300Abstract: A rear vision system having a divided lens configuration and sensor array. The sensor array has a first, second section and third sections. The lens configuration includes a first portion directing a first field of view onto the first section of the sensor array, and a second portion directing a second field of view onto the second section of the sensor array. The sensor array may be a complementary metal oxide semiconductor camera or a charge coupled device camera.Type: GrantFiled: June 29, 2005Date of Patent: April 29, 2008Assignee: Visteon Global Technologies, Inc.Inventors: Daniel K.

Patent number: 6520654Abstract: A thin panel lit cluster including a graphics appliqué with a first and second side and at least one opaque section and one translucent section. A light-carrying panel with a first and second side is positioned such that the first side is adjacent to the second side of the graphics appliqué. The light-carrying panel has at least one opening defined in it and at least one light source is positioned to align with the opening. Opposite the light source, the light-carrying panel has a first light-redirecting area nearest its first side. In another position on the light-carrying panel, there is a second light-redirecting area nearest the second side of the light-carrying panel and opposite a translucent section of the graphics appliqué.Type: GrantFiled: December 29, 2000Date of Patent: February 18, 2003Assignee: Visteon Global Technologies, Inc.Inventors: Daniel K. Angell, Don A. Kees, Paul S. Ewers, Thomas L. Jones, Michael J. Luettgen

Patent number: 5821867Abstract: A transreflective instrument display has a generally planar reverse image light emitting display panel, a transflector surface positioned at a predetermined angle with respect to the display panel. The transflector has a P-plane reflectance and S-plane reflectance. A illuminated pointer is positioned behind the transflector. The display is formed of light transmitted from the pointer and reflecting light from said display panel simultaneously to form an image. The transflector is preferably coated with a coating that increases the reflectivity of the P-plane polarization of the transflector.Type: GrantFiled: December 8, 1995Date of Patent: October 13, 1998Assignee: Ford Motor CompanyInventors: Daniel K. Angell, Kathleen M. Schulz, Scott D. Saari
