Abstract: A vibration isolation system includes multiple isolators between an inner object and an outer housing that surrounds the object. In one example the inner object may be a rack or container that holds electronics, such as printed circuit boards, and the outer housing may be a housing for a missile, such as a supersonic or hypersonic missile. The isolators have flexures to attenuate vibrations, isolating the inner object at least in part from vibrations encountered by the outer housing. The flexures may be oriented in different directions for different isolators to change the resonant frequency of the system for a given axis. In addition the isolators are able to compensate for differences in expansion between the inner object and the outer housing. The isolators may also include multi-part isolators that have spring-loaded wedge elements used to expand the isolators in one or more radial directions.

Abstract: A device for securing a torque bit to a fastener in an object. The novel device includes a structure adapted to apply a force on the torque bit and a mechanism for clamping the structure to the object such that the structure forces the bit to remain engaged with a drive feature of the fastener. In an illustrative embodiment, the structure is bolted to the object, capturing the bit between the structure and the object. Spacers disposed between the structure and the object control the magnitude of the force applied on the bit such that the bit can rotate during torquing. In an alternative embodiment, the structure surrounds the object and is tightened to clamp the structure to the object. An insert disposed between the structure and the bit controls the magnitude of the force applied on the bit in this embodiment.
