An active array heat sink cooled by natural free convection is disclosed. A long extruded heat sink is partitioned into multiple, shorter zones separated by gaps having horizontal baffles. The gaps and baffles serve to act as air vents and air inlets for the convection currents. As such, the heat transfer for the overall heat sink is improved because hot convection currents are vented and replaced by cool ambient air along the length of the heat sink.

Active antenna array heatsink

A spool (), for supporting a fiber optic coil () and a shield () surrounding the spool and fiber optic coil, includes a centrally placed, bolt-receiving opening (). The shield includes a lower shield portion (), which supports the spool and the fiber optic coil, and an upper shield portion (). The upper and lower shield portions are arranged to interfit with each other at an interface (). The upper shield portion has a centrally placed fastener-receiving opening () which is alignable with the centrally placed, bolt-receiving opening of the spool. A bolt () has a head (), a shank () and a threaded end (). The bolt head is engageable with the spool through intermediary structure (). The shank is insertable through the centrally placed, bolt-receiving opening () and the lower shield opening (), for radially centering the assembly and its components. The threaded end is disposed to engage a threaded opening () in a gyroscope assembly support (). A threaded, centrally placed opening () is located in the bolt head. A screw () is couplable with the upper shield portion and screwable into the bolt head threaded opening for securing the upper shield portion both to the lower shield portion and to the bolt.

Reusable, high stiffness, magnetic shield for fiber optic gyroscopes

A suspension for a gyroscopic float assembly in a floating gyroscope system comprises a pair of flexures that each have an outer rim and a plurality of flexure beams extending from the outer rim. A plurality of flexure tabs extend outward from outer perimeter portions of the rims for mounting the flexure assembly to a pair of end caps. A plurality of strain relief passages formed in the rims is arranged to provide relief from thermally induced stresses. A plurality of angular stops formed in inner perimeter portions of the rims is arranged to constrain the flexure against rotation about a selected axis.
