Abstract: A docking module for conventional small form factor disk drives provides, in one embodiment, space for two such disk drives embedded in tray loaders, within a standard 3.5 inches halve height floppy bay. The docking module provides hot swappable insertion and removal of tray loaders together with disk drives. The bay is provided within a housing member. A button attached to a lever mechanism disconnects the docking module connector from the tray loader connector and partially pull out the loader when the button is pushed; An EMI shield fixedly coupled to the tray loaders each provide a barrier to electromagnetic interference.

Abstract: A method of tuning a dielectric resonator uses a ferroelectric element to change the dielectric resonator electric field and hence the resonance frequency of the dielectric resonator.

Abstract: A security barrier made up of a specially constructed bulkhead and a novel security door hingedly mounted within the security bulkhead that provides substantial protection against assault by potential aggressors. The security barrier can be used in various types of sensitive areas, but is particularly well-suited for use in commercial aircraft to separate the passenger compartment from the pilot's compartment and thereby protect the pilots compartment from assault by terrorists and other armed aggressors. The bulkhead is made up of a plurality of sealably interconnected armor protected panels that effectively thwart access to the pilots compartment via the bulkhead. The security door is of a laminate construction that is hingedly mounted within the security bulkhead and uniquely comprises a movable portion movable from a first position to a second position upon the detection of a pressure differential between the passenger compartment and the pilot's compartment.

Abstract: A thin film ferroelectric varactor device comprising a substrate layer, a ferroelectric layer structure and an electrode structure is presented. The ferroelectric layer structure comprises a number of ferroelectric layers and a number of intermediate buffer layers arranged in an alternating manner. At least a first and a second layer of the ferroelectric layers have different Curie temperatures, i.e. the dielectric constant of the first ferroelectric layer has a maximum at a temperature which is different from the temperature at which the dielectric constant of the second ferroelectric layer has a maximum.

Abstract: The present invention relates to a thin film ferroelectric varactor device (10) comprising a substrate layer (1), a ferroelectric layer structure (12) and an electrode structure (91,92). The ferroelectric layer structure (12) comprises a number of ferroelectric layers (2,4) and a number of intermediate buffer layers (3) arranged in an alternating manner. At least a first (2) and a second (4) layer of said ferroelectric layers have different Curie temperatures, i.e. the dielectric constant of the first ferroelectric layer (12) has a maximum at a temperature which is different from the temperature at which the dielectric constant of the second ferroelectric layer (4) has a maximum.
