US Patent:

40192008, Apr 19, 1977

Filed:

Jun 11, 1975

Appl. No.:

5/586107

Inventors:

Larry R. Adkins - Tustin CA
James L. Gates - Costa Mesa CA

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

H01L 2984
H01L 2996
H01L 2978
H04N 300

US Classification:

357 26

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.

Larry R. Adkins - Tustin CA

Assignee:

Rockwell International Corporation - Seal Beach CA

International Classification:

H05K 720

US Classification:

361707

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.

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

G06G 7195

US Classification:

364821

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.

Appl. No.:

5/588102

Rockwell International Corporation - El Segundo CA

International Classification:

H04N 530

US Classification:

178 71

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.
