Patent number: 11926686Abstract: Shape-programmable liquid crystal elastomers. The shape-programmable liquid crystal elastomers being synthesized by filling an alignment cell with liquid crystal monomers. The liquid crystal monomers align to a surface of the alignment cell and then are polymerized with a dithiol chain transfer agent. The alignment cell is configured to impose a director orientation on a portion of the shape-programmable liquid crystal elastomer. For some embodiments, liquid crystal elastomer laminates are prepared by arranging a plurality of liquid crystal elastomers such that a director orientation of each liquid crystal elastomer of the plurality is in registered alignment with an adjacent liquid crystal elastomer of the plurality. The arrangement is secured and the plurality of liquid crystal elastomers cured.Type: GrantFiled: November 23, 2021Date of Patent: March 12, 2024Assignee: United States of America as represented by the Secretary of the Air ForceInventors: Nicholas P Godman, Timothy J White, Hilmar Koerner, Benjamin A Kowalski, Anesia D Auguste, Tyler C Guin

Publication number: 20240025350Abstract: Speaker systems are provided, particularly for mounting in vehicles, such as off-road vehicles, ATVs, UTVs, watercraft and motorcycles. The speaker systems include a linear array of speakers, a housing encasing a backside thereof, and a mounting clamp for coupling to the housing. In some configurations, a speaker system may include a sliding track for receiving a mounting. In some cases, a speaker system may be coupled to a main battery of a vehicle, but is operationally independent from the vehicle. In addition or alternatively, a speaker system may be coupled to a roll over cage and/or a windshield frame of a vehicle.Type: ApplicationFiled: September 29, 2023Publication date: January 25, 2024Inventors: Timothy J. White, Brett A. Triola

Patent number: 10876627Abstract: Calibration and simulation techniques for modeled gear shift events of an automatic transmission of a vehicle comprise obtaining a set of parameters for a modeled gear shift event of the transmission and, based on the set of parameters, modeling forward/aft vehicle acceleration caused by the modeled gear shift event. A shift quality rating system is the utilized to obtain a shift quality rating of the modeled gear shift event based on at least one of the set of parameters and the modeled forward/aft vehicle acceleration. Finally, the techniques determine whether the determined shift quality rating satisfies a shift quality rating threshold and, when the determined shift quality rating fails to satisfy the shift quality rating threshold, a gear ratio gradient for the modeled gear shift event is adjusted and the process is repeated until the determined shift quality rating satisfies the shift quality rating threshold.Type: GrantFiled: September 24, 2019Date of Patent: December 29, 2020Assignee: FCA US LLCInventors: Ryan J Monroe, Mustafa Acar, Avinash Jonnalagadda, Bruce K Geist, Timothy J White, Cory E Bruckner
