Patent number: 10859437Abstract: An apparatus includes a substrate transmissive of electromagnetic energy of at least a plurality of wavelengths, having a first end, a second end, a first major face, a second major face, at least one edge, a length, a width, and a thickness, at least a first output optic that outputs electromagnetic energy the substrate; and a first input optic oriented and positioned to provide electromagnetic energy into the substrate via at least one of the first or the second major face of the substrate. The first output optic is laterally spaced from the first input optic. A number of reflectors and optional absorbers may be positioned proximate the first major face and/or the second major face to structure electromagnetic energy and/or to translate such from the first input optic to the first output optic. The apparatus may be part of a spectrometer or other optical system.Type: GrantFiled: May 10, 2017Date of Patent: December 8, 2020Assignee: CHROMATION, INC.Inventors: James Scholtz, Nadia Pervez, Ioannis Kymissis, Michael Gazes

Publication number: 20200305253Abstract: LED structures (e.g., LED arrays) and fabrication methods can reduce or even eliminate deep etching, and associated defect formation, proximate sites of individual LEDs. Such approaches can achieve desired electrical isolation without deep etching, provide a high conductivity current spreading layer, and, or reduce losses otherwise associated with conventional fabrication approaches. Some implementations advantageously lift off or separate an insulating substrate from a wafer to expose a bottom surface of the epitaxial LED layer and forms a backside contact (e.g., ground plane) overlying the bottom surface. Other implementations isolate deep etching away from sensitive regions and locate the backside contact on a top surface of the epitaxial LED layer. Some implementations form light extraction features (e.g., photonic crystals) on the exposed bottom surface. The top surface of the epitaxial LED layer may be un-doped to improve electrical isolation.Type: ApplicationFiled: May 8, 2020Publication date: September 24, 2020Inventors: Vincent Lee, Ioannis Kymissis, Brian Tull

Patent number: 10663361Abstract: Achieving high spatial resolution in contact sensing for robotic manipulation often comes at the price of increased complexity in fabrication and integration. One traditional approach is to fabricate a large number of taxels, each delivering an individual, isolated response to a stimulus. The proposed sensors include a continuous volume of soft material, e.g., a transparent polymer, and light emitting diodes configured to emit light into the transparent volume that can be received by photodetectors. The location and depth of indentations can be measured between all pairs of light emitting diodes and photodetectors in the set, and this rich signal set can contain the information needed to pinpoint contact location with high accuracy using regression algorithms.Type: GrantFiled: October 12, 2017Date of Patent: May 26, 2020Assignee: THE TRUSTEES OF COLUMBIA UNIVERSITY IN THE CITY OF NEW YORKInventors: Matei Ciocarlie, Pedro Piacenza, Ioannis Kymissis

One traditional approach is to fabricate a large number of taxels, each delivering an individual, isolated response to a stimulus. In contrast, proposed sensor includes a continuous volume of soft material, e.g., a piezoresistive elastomer with a number of terminals embedded inside. Piezoresistive effects can be measured between all pairs of terminals in the set, and this rich signal set can contain the information needed to pinpoint contact location with high accuracy using regression algorithms. Submillimeter median accuracy can be demonstrated in locating contact on a 10 mm by 16 mm sensor using only four terminals (creating six unique pairs).Type: GrantFiled: March 30, 2017Date of Patent: October 23, 2018Assignee: The Trustees of Columbia University in the City of New YorkInventors: Matei Ciocarlie, Ioannis Kymissis, Pedro Piacenza, Steve Jeung Hoon Park

Patent number: 10041689Abstract: An insulated heating-unit cover having an opening to permit air to circulate around the heating-source when a vent disposed at the top of the cover is opened, allowing heat into a space. The cover can include a heating-unit temperature sensor disposed within a space covered by the cover and a controller in wireless communication with a space temperature sensor located at a distance away from the heating-unit.
