Patent number: 11762131Abstract: A variable focus optical device (100) can include first optically transparent membrane (102) and a second membrane (104) that at least partially define a chamber (106) retaining an optically transparent liquid. A transparent piston (110) is attached to the second membrane (104). At least one actuator (112a-c) is operatively coupled to the transparent piston (110) and configured to move to change a focal length of the variable focus optical device (100) via actuation of the transparent piston (110). Three curved bimorph actuators (112a-c) can surround and be coupled to the piston (110) for actuation of the piston (110) to generate a plano-convex or plano-concave lens via the membranes (102, 104). A smart eyeglasses system includes a pair of variable focus optical devices (100), an object distance sensor, a battery, optional eye-tracking camera(s), and a microcontroller, collectively used for purposes of sensing distance of objects and adjusting said focal length via the variable focus optical devices (100).Type: GrantFiled: September 29, 2020Date of Patent: September 19, 2023Assignee: UNIVERSITY OF UTAH RESEARCH FOUNDATIONInventors: Carlos Mastrangelo, Nazmul Hasan, Kim Hanseup

Patent number: 10502724Abstract: A zero-power digital chemical analyzer can include a chemically-selective percolation switch. The chemically selected percolation switch can include a positive electrode and a negative electrode separated from the positive electrode by a gap. A binding agent can be located at binding sites in the gap. The binding agent can be selective for binding to a target chemical compound. The binding sites can be distributed in the gap so that target chemical molecules binding to the binding sites can form an electrically conductive pathway via a natural percolation phenomenon between the electrodes when the ambient concentration of the target chemical compound reaches a threshold concentration.Type: GrantFiled: December 12, 2016Date of Patent: December 10, 2019Assignee: University of Utah Research FoundationInventors: Hanseup Kim, Carlos Mastrangelo

Publication number: 20030232203Abstract: A composition, method and use is disclosed for a porous plug that functions as an electro-osmotic pump. The polymer eliminates any back pressure effects while enhancing the electro-osmotic flow in a channel. The pump is bach fabricated by surface micromachining on top of a silicon wafer. The pump device is driven by an alternating zero-average injected current signal at low frequencies producing a bubble-free electro-osmotic flow with a reversible net movement. The device is capable of an average water-air interface velocity of 1.8 &mgr;m/second at 0.8 Hz. The velocity may be increased from between 4.8-13.9 &mgr;m/second by necking down the channel size.Type: ApplicationFiled: January 17, 2003Publication date: December 18, 2003Applicants: The Regents Of The University Of Michigan, The Regents Of The University Of CaliforniaInventors: Senol Mutlu, Ponnambalam Selvaganapathy, Carlos Mastrangelo, Frantisek Svec, Jean M.J.
