Patent number: 11933899Abstract: Through discrimination of the scattered signal polarization state, a lidar system measures a distance through semi-transparent media by the reception of single or multiple scattered signals from a scattering medium. Combined and overlapped single or multiple scattered light signals from the medium can be separated by exploiting varying polarization characteristics. This removes the traditional laser and detector pulse width limitations that determine the system's operational bandwidth, translating relative depth measurements into the conditions of two surface timing measurements and achieving sub-pulse width resolution.Type: GrantFiled: January 24, 2022Date of Patent: March 19, 2024Assignees: The Regents of the University of Colorado, LiteWave Technologies, Inc.Inventors: Jeffrey P.

Publication number: 20240052859Abstract: 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: October 13, 2023Publication date: February 15, 2024Applicant: The Regents of the University of Colorado, a body corporateInventors: Christoph Matthias Keplinger, Eric Lucas Acome, Nicholas Alexander Kellaris, Shane Karl Mitchell
