Abstract: A system configured to provide thermal regulation and vibration isolation to one or more electronic components. The system includes a sensor chassis defining an interior chamber, an electronics housing in the interior chamber of the sensor chassis, a thermoelectric cooler coupled between the sensor chassis and the electronics housing, a thermal strap coupled to the sensor chassis, and at least one isolator coupled to the sensor chassis. The system may also include an insulating material, such as Aerogel, in the interior chamber of the sensor chassis and extending around the electronics housing.

Abstract: An isolator configured to isolate a payload from unwanted vibrations and shocks. The isolator includes a housing having a first end and a second end opposite the first end, a primary chamber defined in the housing, a backpressure chamber defined in the housing, a conduit placing the primary chamber in fluid communication with the backpressure chamber, a backpressure membrane in the housing proximate the first end, an elastomer dome in the housing proximate the second end, and a shaft connected to the elastomer dome. The primary chamber and the backpressure chamber are between the backpressure membrane and the elastomer dome. The shaft is configured to be connected to the payload.

Abstract: A watercraft includes a hull having inner and outer surfaces and at least one collapsible strake coupled to the hull. The collapsible strake includes a movable skin hingedly coupled to the hull. The collapsible strake also includes a dampening element and a negative stiffness element each extending from an inner surface of the movable skin to the outer surface of the hull. The movable skin is configured to rotate between an uncollapsed configuration having a first stiffness and a collapsed configuration having a second stiffness greater than the first stiffness.

Abstract: An adjustable negative stiffness mechanism is disclosed. The adjustable negative stiffness mechanism includes a central shaft, an outer annular member extending around the central shaft, at least two negative stiffness elements extending between the central shaft and the annular member, and an actuator coupled to the negative stiffness elements. Each of the negative stiffness elements has an inner end coupled to the central shaft and an outer end engaging the annular member. The actuator is configured to compress and expand the negative stiffness elements to adjust a negative stiffness mechanical response exhibited by the negative stiffness elements.
