Publication number: 20240082024Abstract: A stent device includes generally cylindrical rings aligned along a longitudinal axis, and interconnected by interconnecting members. Each interconnecting member includes a first coupling end, a second coupling end, and an elongate portion therebetween. The first coupling end, the elongate portion, and the second coupling end combine in either a first orientation or a second orientation, which are substantially mirror images. For each interconnecting member, the first coupling end can intersect with a midpoint of a transition region of a substantially repeating curved segment on one of the rings, and the second coupling end can intersect with a midpoint of a curved segment of a different and immediately adjacent ring. The interconnecting members can be arranged in rows extending longitudinally along the device. Along each row, consecutive interconnected members alternate between the first orientation and the second orientation. A cover may be provided over the stent device.Type: ApplicationFiled: November 16, 2023Publication date: March 14, 2024Applicant: ATRIUM MEDICAL CORPORATIONInventors: John LANE, David HEIM, Christine SCHICK, Jennifer LETZELTER, Susan HAMELIN

Publication number: 20230350236Abstract: Provided herein is a photonic modulator and methods for controlling a photonic modulator that can control the phase and/or amplitude of photons being transmitted through the modulator to minimize photonic loss while remaining power efficient and operating at high speeds. The photonic modulator can include a substrate with a pair of piezoelectric cantilevers spaced apart from one another by a gap, with a photonic waveguide disposed in the substrate that extends across the modulator and bridges the gap between the piezoelectric cantilevers. In one or more examples, the piezoelectric cantilevers can be configured to move away from the substrate in response to an electrical signal, such that a refractive index of the photonic waveguide is altered.Type: ApplicationFiled: April 28, 2023Publication date: November 2, 2023Applicants: The MITRE Corporation, National Technology & Engineering Solution of Sandia, LLC, MIT - Massachusetts Institute of TechnologyInventors: David HEIM, Henry WEN, Mark DONG, Hugo LAROCQUE, Andrew LEENHEER, Gerald GILBERT, Matthew EICHENFIELD, Mikkel HEUCK, Dirk ENGLUND

Patent number: 10243363Abstract: Systems and methods are provided, which provide for the de-centralization of the logic necessary to perform electrical optimization of any contained electrical system. The systems and methods de-centralize, or distribute, electrical optimization logic into intelligent devices which are locally connected to both the generation and loads, in such a way that control can be asserted over these resources. The inventive systems and methods require less infrastructure and communication backbone to IT/Data Center infrastructure than are typically required by previous systems and methods known in the art.Type: GrantFiled: March 17, 2016Date of Patent: March 26, 2019Assignee: Open Access Technology International, Inc.Inventors: Sasan Mokhtari, Khashayar Nodehi Fard Haghighi, Erik Alan Amundson, David Heim, Dean Eriksson, Anthony Charles Sorvari

Publication number: 20180114283Abstract: A process/method is provided, which facilitates resource optimization considering all dispatchable resources as well as user rate charges, which are rate charges comprised of a base rate plus an incremental excess fee associated with designated usage parameters. The proposed system and method may utilize inputs to construct a periodic load profile over varied periods of time. The disclosure relates to forming a periodic load profile over varied periods of time based upon considerations of short-term and long-term cost for uses within microgrids to create microgrid resource schedules that optimize usage of loads and generation resources within a microgrid for minimizing both short-term energy charges and long-term demand charges while increasing microgrid resource efficiencies.Type: ApplicationFiled: October 23, 2017Publication date: April 26, 2018Applicant: Open Access Technology International, Inc.Inventors: Sasan Mokhtari, Ebrahim Vaahedi, Khashayar Nodehi Fard Haghighi, Girish Thirukkurungudi Sekar, Guillermo Irisarri, David Heim, Long Duong, Ali Ipakchi
