Publication number: 20230238266Abstract: An apparatus includes a substrate holder, a first actuator to rotate the substrate holder, a second actuator to move the substrate holder linearly, a first sensor to generate one or more first measurements or images of the substrate, a second sensor to generate one or more second measurements of target positions on the substrate, and a processing device. The processing device estimates a position of the substrate on the substrate holder and causes the first actuator to rotate the substrate holder about a first axis. The rotation causes an offset between a field of view of the second sensor and a target position on the substrate due to the substrate not being centered on the substrate holder. The processing device causes the second actuator to move the substrate holder linearly along a second axis to correct the offset. The processing device determines a profile across a surface of the substrate based on the one or more second measurements of the target positions.Type: ApplicationFiled: January 25, 2022Publication date: July 27, 2023Inventors: Patricia Schulze, Gregory John Freeman, Michael Kutney, Arunkumar Ramachandraiah, Chih Chung Chou, Zhaozhao Zhu, Ozkan Celik

Patent number: 10794453Abstract: A miniturized laminar gear box possessing high torque densities and methods of manufacturing the same. The high torque density is possible by directing the output shaft of the planetary stages through the sun gear and behind the input shaft. This allows the input shafts of the planetary stages to face towards the interior of the gearbox and provides a rotary shaft for the spur stages housed in between the planetary stages.Type: GrantFiled: March 27, 2019Date of Patent: October 6, 2020Assignees: THE REGENTS OF THE UNIVERSITY OF COLORADO, A BODY CORPORATE, COLORADO SCHOOL OF MINESInventors: Richard Weir, Stephen Huddle, Barathwaj Murali, Ozkan Celik

Patent number: 10123929Abstract: An exoskeleton device and method of using the same is provided that helps rehabilitate limbs such has the lower arm. Embodiments of the exoskeleton device have multiple degrees of freedom so that a limb such as the lower arm may flex or rotate in multiple directions to establish or re-establish neural connections in the brain. With the lower arm example, a person may grasp a handle in the exoskeleton and then flex the lower arm about a pronation/supination axis, a flexion/extension axis, and/or an abductor/adductor axis. The exoskeleton device has several modes of operation where actuators can aid the person's motion, resist the person's motion, or passively allow free motion of the person's limb.Type: GrantFiled: June 17, 2015Date of Patent: November 13, 2018Assignee: COLORADO SCHOOL OF MINESInventor: Ozkan Celik
