Publication number: 20220381268Abstract: An electro-hydraulic actuator includes a deformable shell defining an enclosed internal cavity and containing a liquid dielectric, first and second electrodes on first and second sides, respectively, of the enclosed internal cavity. An electrostatic force between the first and second electrodes upon application of a voltage to one of the electrodes draws the electrodes towards each other to displace the liquid dielectric within the enclosed internal cavity. The shell includes active and inactive areas such that the electrostatic forces between the first and second electrodes displaces the liquid dielectric within the enclosed internal cavity from the active area of the shell to the inactive area of the shell. The first and second electrodes, the deformable shell, and the liquid dielectric cooperate to form a self-healing capacitor, and the liquid dielectric is configured for automatically filling breaches in the liquid dielectric resulting from dielectric breakdown.Type: ApplicationFiled: August 8, 2022Publication date: December 1, 2022Applicant: The Regents of the University of Colorado, a body corporateInventors: Christoph Matthias Keplinger, Eric Lucas Acome, Nicholas Alexander Kellaris, Shane Karl Mitchell

Patent number: 11496045Abstract: The present disclosure provides methods and circuits of multi-output hybrid voltage regulators that generate multiple lower level DC voltages lower than the magnitude of an input voltage provided to an input node of the regulator. The disclosed methods and circuits can be applied to today's Large conversion ratio DC-DC converters that allow them to support same power conversion functionality for multiple output voltages with one core switched capacitor network sharing passive components and switches with less voltage ratings, and therefore, reduce the implementation space to save cost as well as improve efficiency. Sample applications include, but are not limited to, PoL converters for data centers and telecommunication systems with better efficiency and compactness for higher conversion ratio.Type: GrantFiled: August 12, 2019Date of Patent: November 8, 2022Assignee: THE REGENTS OF THE UNIVERSITY OF COLORADO, A BODY CORPORATEInventors: Ratul Das, Hanh-Phuc Le

Publication number: 20220346943Abstract: A modular IOL system including intraocular primary and secondary components, which, when combined, form an intraocular optical correction device, wherein the secondary component is placed on the primary component within the perimeter of the capsulorhexis, thus avoiding the need to touch or otherwise manipulate the capsular bag. The secondary component may be manipulated, removed, and/or exchanged for a different secondary component for correction or modification of the optical result, on an intra-operative or post-operative basis, without the need to remove the primary component and without the need to manipulate the capsular bag. The primary component may have haptics extending therefrom for centration in the capsular bag, and the secondary component may exclude haptics, relying instead on attachment to the primary component for stability. Such attachment may include actuatable interlocking members.Type: ApplicationFiled: July 1, 2022Publication date: November 3, 2022Applicants: Alcon Inc., The Regents of the University of Colorado, a body corporateInventors: Malik Y.

Patent number: 11486421Abstract: Hydraulically-amplified, self-healing, electrostatic transducers that harness electrostatic and hydraulic forces to achieve various actuation modes. Electrostatic forces between electrode pairs of the transducers generated upon application of a voltage to the electrode pairs draws the electrodes in each pair towards each other to displace a liquid dielectric contained within an enclosed internal cavity of the transducers to drive actuation in various manners. The electrodes and the liquid dielectric form a self-healing capacitor whereby the liquid dielectric automatically fills breaches in the liquid dielectric resulting from dielectric breakdown. Due to the resting shape of the cavity, a zipping-mechanism allows for selectively actuating the electrodes to a desired extent by controlling the voltage supplied.Type: GrantFiled: March 4, 2019Date of Patent: November 1, 2022Assignee: The Regents of the University of Colorado, a body corporateInventors: Christoph Matthias Keplinger, Eric Lucas Acome, Nicholas Alexander Kellaris, Shane Karl Mitchell, Timothy G.
