Patent number: 11904986Abstract: An apparatus includes a structure comprising a predetermined breakable region and a mechanical actuator disposed at or proximate the predetermined breakable region. The mechanical actuator comprises an impact member coupled to a spring arrangement, and a restraint member operably coupled to the spring arrangement. A trigger source is operably coupled to an electrical power source. The trigger source, in response to receiving current from the electrical power source, is configured to release or break the restraint member so as to allow the spring arrangement to forcibly move the impact member into contact with, and break, the predetermined breakable region.Type: GrantFiled: December 21, 2020Date of Patent: February 20, 2024Assignee: XEROX CORPORATIONInventors: Christopher L. Chua, Norine E. Chang, Julie Ann Bert, Scott J. Limb, Steven Neltner, Eric Cocker

Patent number: 11302561Abstract: Transfer elements include an adhesion element having a higher Young's modulus at a lower temperature and a lower Young's modulus at a higher temperature. Heating elements are operable to change an operating temperature of each adhesion element in response to an input. A controller is coupled to provide the inputs to the heating elements to cause a change in temperature at least between the higher and lower temperature. The change in temperature causes the transfer elements to selectably hold objects to and release the objects in response to changes between the higher and lower Young's moduli of transfer elements.Type: GrantFiled: November 12, 2019Date of Patent: April 12, 2022Assignee: Palo Alto Research Center IncorporatedInventors: Yunda Wang, Jengping Lu, Qian Wang, Norine E.

Patent number: 9624116Abstract: A mobile HEB and TEP mitigation device includes a mobile body capable of movement within or upon a body of water. Located within the mobile body is a hydrodynamic separation system which includes a water inlet, a hydrodynamic separation unit and a collection tank. The hydrodynamic separation unit includes two outputs, one for a clean stream output line containing clean water and arranged to re-circulate the clean water, and another for a concentrate stream output line, the concentrate stream output line configured to place concentrated water containing potentially harmful bio-organic materials into the collection tank. Also included on the mobile body is a power source and an engine/steering unit, wherein the steering portion of the engine/steering unit provides a capacity to move the mobile body in an intended direction. The mitigation device may also be used as an embedded part of an on-shore arrangement.Type: GrantFiled: January 14, 2013Date of Patent: April 18, 2017Assignee: PALO ALTO RESEARCH CENTER INCORPORATEDInventors: Armin R. Volkel, Meng H. Lean, Norine E. Chang, Huangpin B. Hsieh

Patent number: 9433880Abstract: This invention is based on size and mass separation of suspended particles, including biological matter, which are made to flow in a spiral channel. On the spiral sections, the inward directed transverse pressure field from fluid shear competes with the outward directed centrifugal force to allow for separation of particles. At high velocity, centrifugal force dominates and particles move outward. At low velocities, transverse pressure dominates and the particles move inward. The magnitudes of the two opposing forces depend on flow velocity, particle size, radius of curvature of the spiral section, channel dimensions, and viscosity of the fluid. At the end of the spiral channel, a parallel array of outlets collects separated particles. For any particle size, the required channel dimension is determined by estimating the transit time to reach the side-wall. This time is a function of flow velocity, channel width, viscosity, and radius of curvature.Type: GrantFiled: November 30, 2006Date of Patent: September 6, 2016Assignee: Palo Alto Research Center IncorporatedInventors: Meng H. Lean, Jeonggi Seo, Ashutosh Kole, Norine E. Chang, Scott Jong Ho Limb
