Title: System for producing dithered images from continuous-tone image data
Inventor: ULICHNEY ROBERT A
IPC: H04N1/40
Filed: 1988-03-16
Granted: 1993-04-13
Abstract: ABSTRACT OF THE DISCLOSURE      A digital image processing system for converting continuous tone pixel values representing an image into halftone or dithered pixel values, with the dithered pixel values representing each pixel having fewer bits than are used to represent each pixel in the continuous tone image.          The continuous tone pixel for a line of pixels is loaded into an input buffer circuit having a plurality of storage locations, with each location storing the continuous-tone values for one pixel.  Iteratively, the pixel value from each location is modified by a perturbed weighted error value, and then quantized to form the output halftone or dithered pixel value.  An error value is then determined which is used in processing of subsequent continuous tone pixel values.  The processing of the continuous tone pixel values proceeds in a serpentine manner over the image, that is, processing of adjacent lines of the continuous tone pixel data proceeds in opposite directions.

Title: Code excited linear predictive vocoder
Inventor: KETCHUM RICHARD H
IPC: G10L19/04
Filed: 1988-05-16
Granted: 1995-06-06
Abstract: Apparatus for encoding speech using an improved code excited linear predictive (CELP) encoder using a recursive computational unit. In response to atarget excitation vector that models a present frame of speech, the computational unit utilizes a finite impulse response linear predictive coding (LPC) filter and an overlapping codebook to determine a candidate excitation vector from the codebook that matches the target excitation vector after searching the entire codebook for the best match. For each candidate excitation vector accessed from the overlapping codebook, only one sample of the accessed vector and one sample of the previously accessed vector must have arithmetic operations performed on them to evaluate the new vector rather than all of the samples as is normal for CELP methods. For increased performance, a stochastically excited linear predictive (SELP) encoder is used in series with the adaptive CELP encoder. The SELP encoder is responsive to the difference between the target excitation vector and the best matched candidate excitation vector to search its own overlapping codebook in a recursive manner to determine a candidate excitation vector that provides the best match. Both of the best matched candidate vectors are used in speech synthesis.

Title: Radio trunking fault detection system
Inventor: HALL NANCY L
IPC: G08C25/02
Filed: 1988-10-13
Granted: 1992-02-04
Abstract: RADIO TRUNKING FAULT DETECTION SYSTEM           ABSTRACT A radio frequency repeater system includes independent error detection units which detect redundant and overlapping error conditions of the RF repeater stations.   The error detection units notify the site controller and/or a system manager of the error conditions, and the failed repeater stations are removed from active service.  The error detection units are then used to simulate actual service for the failed stations so that the stations can be placed back into service once they begin operating properly again.  Because the error detection units operate independently of the other components in the repeater system, they can be used to trigger failure recovery mechanisms without becoming ineffective due to failure of other components.

Abstract: Abstract Of The Disclosure A method of artificially sealing cracks, fissures or  other  voids   in  earth  strata  under  alkaline conditions,   or  in  alkaline  structural  materials. Sealing is effected by induced precipitation of calcium carbonate,  usually in the form of calcite,  either  in alkaline   rocks,   in   other   rocks   where   alkaline groundwaters are present, or in structures of alkaline materials  such  as  cement  or  marble.
