Publication number: 20200173026Abstract: Disclosed herein are implementations of a particles-transferring system, particle transferring unit, and method of transferring particles in a pattern. In one implementation, a particles-transferring system includes a first substrate including a first surface to support particles in a pattern, particle transferring unit including an outer surface to be offset from the first surface by a first gap, and second substrate including a second surface to be offset from the outer surface by a second gap. The particle transferring unit removes the particles from the first surface in response to the particles being within the first gap, secures the particles in the pattern to the outer surface, and transports the particles in the pattern. The second substrate removes the particles in the pattern from the particle transferring unit in response to the particles being within the second gap. The particles are to be secured in the pattern to the second surface.Type: ApplicationFiled: February 4, 2020Publication date: June 4, 2020Inventors: Yunda Wang, Sourobh Raychaudhuri, JengPing Lu, Eugene M. Chow, Julie A. Bert, David Biegelsen, George A. Gibson, Jamie Kalb

Patent number: 10608041Abstract: Transitioning conventional x-ray detector materials and structures to bendable or flexible (e.g., plastic) substrates makes them rugged against breakage when dropped but exposes the detectors to damage if bent. Disclosed are bendable digital x-ray detector structures that are rugged with regard to bending as well as dropping. The structures provide strain matching between layers so that a detector backplane is in and/or near the mechanical neutral plane and therefore less susceptible to bending stress.Type: GrantFiled: April 12, 2018Date of Patent: March 31, 2020Assignee: PALO ALTO RESEARCH CENTER INCORPORATEDInventors: Robert A. Street, Julie A. Bert, John C. Knights

Patent number: 10558204Abstract: The system and method described below allow for real-time control over positioning of a micro-object. A movement of at least one micro-object suspended in a medium can be induced by a generation of one or more forces by electrodes proximate to the micro-object. Prior to inducing the movement, a simulation is used to develop a model describing a parameter of an interaction between each of the electrodes and the micro-object. A function describing the forces generated by an electrode and an extent of the movement induced due to the forces is generated using the model. The function is used to design closed loop policy control scheme for moving the micro-object towards a desired position. The position of the micro-object is tracked and taken into account when generating control signals in the scheme.Type: GrantFiled: March 24, 2017Date of Patent: February 11, 2020Assignee: Palo Alto Research Center IncorporatedInventors: Ion Matei, Jeng Ping Lu, Saigopal Nelaturi, Julie A.

Patent number: 10353083Abstract: A monolithic stack of thin x-ray detector layers capable of energy resolution is described. The stack is made of detector layers thinner and closer together than other x-ray detectors, avoiding the need to correct for parallax shifts. Moreover, the system's ability to combine multiple x-ray detector images accurately enables it to resolve x-ray energy information better than existing systems. The system can include a monolithic stack of x-ray detector layers, wherein a respective detector layer contains an x-ray detector and is less than 2 millimeters thick.Type: GrantFiled: September 12, 2017Date of Patent: July 16, 2019Assignee: PALO ALTO RESEARCH CENTER INCORPORATEDInventors: Robert A.

Patent number: 10197831Abstract: A flexible TFT backplane includes, a flexible substrate, a first set of address line contacts associated with the substrate, and a second set of address line contacts associated with the substrate. The first set of address line contacts and the second set of address line contacts are located at opposite sides of the substrate from each other, defining a vertical direction. A first set of address lines designed to run in one of the vertical direction and a diagonal or non-vertical direction with respect to the defined vertical direction, with the first set of address lines connected to the first set of address line contacts. Also provided is a second set of address lines designed to run in one of a diagonal or non-vertical direction with respect to the defined vertical direction, and a combination of diagonal and horizontal directions with respect to the vertical direction, with the second set of address lines connected to the second set of address line contacts.Type: GrantFiled: December 18, 2017Date of Patent: February 5, 2019Assignee: PALO ALTO RESEARCH CENTER INCORPORATEDInventors: Robert A.

Patent number: 9404804Abstract: A thermal sensor includes an array of pixels, each having a membrane mounted on legs over a reflector, forming a Fabry-PĂ©rot cavity. Each membrane includes an infrared (IR) absorbing material that defines multiple spaced-apart openings separated by micron-level distances that decrease thermal capacity and increase IR absorption of the membrane. Regular pitch distances between adjacent openings provides narrowband IR absorption, with pitch distances below 7.1 ?m facilitating the detection of IR radiation wavelengths below 7.5 ?m. Multispectral thermal imaging is achieved by arranging the pixels in repeated groups (superpixels), where each superpixel detects the same set of IR radiation wavelengths. Thermal imaging devices include thermal sensors, IR lenses and device control circuitry arranged in a camera-like manner.Type: GrantFiled: April 2, 2015Date of Patent: August 2, 2016Assignee: Palo Alto Research Center IncorporatedInventors: Victor Liu, Bernard D.
