Patent number: 12018733Abstract: Methods, systems, and devices are described for isolating a crystal oscillator assembly from shock and/or vibration inputs. A system may include one or more vibration isolators coupled between the crystal oscillator assembly and the base structure, and each of the vibration isolators may include a spring material layer and a damping material layer. The spring material layer may provide a spring force between the crystal oscillator assembly and the base structure. The damping material layer may be adhered to at least one side of the spring material layer, and may provide a damping force between the crystal oscillator assembly and the base structure. Some vibration isolators may further include a constraint layer adhered to the damping material layer, such that the damping material layer is coupled between the constraint layer and the spring material layer.Type: GrantFiled: August 26, 2021Date of Patent: June 25, 2024Assignee: Viasat, Inc.Inventors: Steven Shrinkle, Kenneth Larson, Christopher Haas

Publication number: 20240009012Abstract: A stent delivery system is adapted to deliver and release a self-expanding stent with improved force transmission efficiency and reduced energy loss. The stent delivery system includes an inner member including a stent receiving region, a proximal member that includes a buckle-reducing member that is adapted to reduce collapsibility within the proximal member, and a deployment sheath that extends coaxially about the inner member and the proximal member and is movable between a position in which the deployment sheath constrains the self-expanding stent and a position in which the deployment sheath does not constrain self-expanding stent, the deployment sheath including a stretch-reducing member that is adapted to reduce stretchability within the deployment sheath, wherein a reduced collapsibility of the proximal member and a reduced stretchability of the deployment sheath together reduce energy loss within the stent delivery system.Type: ApplicationFiled: July 7, 2023Publication date: January 11, 2024Applicant: Boston Scientific Scimed, Inc.Inventors: Derek Kenneth Larson, Michael William Nagel, Wade Michael Felska
