Publication number: 20230418273Abstract: The system and method described 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 voltage patterns in the scheme.Type: ApplicationFiled: September 1, 2023Publication date: December 28, 2023Inventors: Ion Matei, Jeng Ping Lu, Saigopal Nelaturi, Julie A. Bert, Lara S. Crawford, Armin R. Volkel, Eugene M. Chow

Publication number: 20230366093Abstract: Disclosed herein are techniques for transferring particles in a pattern. In one implementation, a particle-transferring system includes a first substrate comprising a first surface configured to support a plurality of particles in a non-uniform pattern, and a particle transfer unit configured to remove the plurality of particles from the first surface in response to the plurality of particles being within a first gap. The system also includes a second substrate configured to remove the plurality of particles from the particle transfer unit and secure the plurality of particles to the second surface in response to the plurality of particles being within a second gap. The particle transfer unit is configured to transfer the plurality of particles and maintain the non-uniform pattern regardless of the positions of the plurality of particles, which are not predefined to fit features of the particle transfer unit.Type: ApplicationFiled: July 12, 2023Publication date: November 16, 2023Inventors: Yunda Wang, Sourobh Raychaudhuri, JengPing Lu, Eugene M.

Patent number: 11772964Abstract: Disclosed are methods and systems of controlling the placement of micro-objects on the surface of a micro-assembler. Control patterns may be used to cause electrodes of the micro-assembler to generate dielectrophoretic (DEP) and electrophoretic (EP) forces which may be used to manipulate, move, position, or orient one or more micro-objects on the surface of the micro-assembler. The control patterns may be part of a library of control patterns.Type: GrantFiled: February 4, 2022Date of Patent: October 3, 2023Assignee: Xerox CorporationInventors: Anne Plochowietz, Bradley Rupp, Jengping Lu, Julie A.

Patent number: 11732362Abstract: 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: GrantFiled: February 4, 2020Date of Patent: August 22, 2023Assignees: Xerox Corporation, Palo Alto Research Center IncorporatedInventors: Yunda Wang, Sourobh Raychaudhuri, JengPing Lu, Eugene M.

Patent number: 10825855Abstract: Bending a flexible x-ray detector to image a curved structure or object will distort the object appearance when compared to an image captured by a flat/rigid detector. An image distortion of this type can be corrected when the shape (relative bend position) of the x-ray detector is known. Incorporating strain sensors on the flexible x-ray detector makes it possible to record the local bend of the flexible x-ray detector when an image is taken. This shape information can be used to either label or correct for the image distortions created by bending the x-ray detector to assist users more accustomed to viewing images produced by flat/rigid x-ray detectors.Type: GrantFiled: December 13, 2018Date of Patent: November 3, 2020Assignee: PALO ALTO RESEARCH CENTER INCORPORATEDInventors: Julie A.
