A low profile, low loss, wide band, wide scan volume radome assembly is provided for an antenna. The radome assembly includes a fabric radome element disposable over the antenna, first radome securing elements securably embedded within the fabric radome element and second radome securing elements securably embedded within the antenna. The second radome securing elements are respectively engageable with the first radome securing elements to thereby secure the fabric radome element over the antenna.

An radio-frequency (RF) interposer enables low-cost, high-performance RF interconnection of two or more large-area printed wiring boards (PWBs). The RF interposer may be provided as a multi-port coaxial structure embedded in a metal (or metalized) carrier. The RF interposer may include one or more conductive shims having spring fingers to provide contact across air-gaps between a PWB RF ground plane and a ground plane of the RF interposer. Retractable pins may be used as the coaxial transmission line center conductors. The RF interposer may be provided as an N&#xd7;M grid of unit cells each having one or more RF ports and a cavities to provide clearance for a PWB component.

In one aspect, a system includes a first circuit board that includes integrated circuits, a first thermal spreader coupled to the integrated circuits of the first circuit board, a first compliant board coupled to the first circuit board, a second circuit board that includes integrated circuits and a second thermal spreader coupled to the integrated circuits of the second circuit board. The first circuit board and the first thermal spreader have a first thickness. The second daughter board and the second thermal spreader have a second thickness. The system further includes a second compliant board coupled to the second circuit board, a board assembly coupled to first and second compliant boards and a cold-plate assembly in contact with the first and second thermal spreaders. Either of the first or the second compliant boards is configured to expand or contract to account for the differences between the first and second thicknesses.

A tape storage system ( ) includes a rack assembly ( ), a plurality of cartridges ( ), a first tape drive ( ) and a second tape drive ( ). The rack assembly ( ) includes a rotatable magazine mount ( ), a cartridge magazine ( ) secured to the magazine mount ( ), and a magazine mover ( ) to rotate the cartridge magazine ( ). The tape storage system ( ) also includes a first transport assembly ( ) to transport one of the cartridges ( ) between the cartridge magazine ( ) and the first tape drive ( ). Uniquely, the cartridge magazine ( ) rotates to position one of the cartridges ( ) over the first transport assembly ( ). The tape storage system ( ) can also include a second transport assembly ( ) for transporting one of the cartridges ( ) between the cartridge magazine ( ) and the second tape drive ( ). With this design, the rack assembly ( ) can efficiently transport two different sized cartridges ( A, B).
