Abstract: A slotted file is created by connecting two side walls and a back wall. The side walls have etched grooves facing directly across from each other. The platelet has flanges that fit into the grooves. In one embodiment, a completed cube is formed when the platelets fill the slotted file.

Abstract: The Ceramic frames and capsules for Z-axis modules shown herein are formed by placing chips 10 into a ceramic frame 12, breaking apart the frame 12 into sub-frames 26, and bonding the sub-frames 26 into a module 30. The sub-frames 26 may be separated by ceramic sub-backings 28. Each sub-frame 26 and sub-backing 28 forms a capsule 22.

Abstract: An acousto-electric convolver having a relatively long effective interaction region for counter-propagating surface acoustic waves and, therefore, a relatively large time-bandwith product implemented by distributing a coupler, such as a multistrip coupler or an array of interdigital transducer taps, over a plurality of parallel-connected single-channel acousto-electric convolvers.

Abstract: Monolithic acoustoelectric signal storage device and means for generating a surface acoustic wave on piezoelectric material and propagating the wave into a storage region of the device. An electric field applied across a storage structure in the storage region of the device interacts with the electric field associated with the surface acoustic wave to produce a holographic replica of the wave in a spatially varying distribution of charge trapped at a solid dielectric-dielectric interface. The stored waveform may then be read out at a later time or, in nonlinear signal processing applications, the electric field of a subsequently generated surface acoustic wave may be propagated into the storage region to interact with the trapped charge to produce an output signal.

Abstract: Monolithic acoustoelectric imager using a multistrip coupled convolver. The multistrip coupler of the convolver senses the electric fields associated with counter-propagating surface acoustic waves on a piezoelectric film. The interaction product of the sensed electric fields scans a screen including one or more strips of radiation-sensitive semiconductor material and the convolver output is modulated by the varying intensity of illumination from an image projected onto the screen.
