Patent CA-2045961-A1 (CA)
Title: Abort processing in pipelined communication
Inventor: GUPTA AMAR
IPC: H04L29/06
Filed: 1991-06-28
Abstract: ABORT PROCESSING IN PIPELINED COMMUNICATION     A method of processing abort signals in a pipe-lined communication system, wherein an abort signal generated in a first processing module is generated in response to an error condition occurring on processing an information packet being transmitted from a second processing module located adjacent to and immediately upstream of the first module, with respect to the direc-tion of flow of information. The processing module re-ceiving the abort signal aborts its own operation, to the extent of the current packet being processed, but propagates the abort signal to a third,  adjacent up-stream processing module only if the third adjacent processing module is still processing the same informa-tion packet that is being transmitted from the second processing module to the first processing module.

Title: Autodeposition emulsion for selectively protecting metallic surfaces
Inventor: BROWNE ALAN R
IPC: G03F7/16
Filed: 1990-12-14
Abstract: Generally, the invention relates to the technical field of autodeposition emulsions and methods of selectively coating metallic surfaces therewith, especially those surfaces which are subjected to etchant baths as the surfaces are being processed as circuit traces for electronic circuit boards. A coating of resin and photoactive functionality is autodeposited from an emulsion onto a metallic substrate in order to selectively protect the substrate from corrosive environments such as etchant processes. An acid and oxidizing agent are included in the emulsion so that when the substrate is immersed in the emulsion the resin and photoactive functionality autodeposits. The resulting coating can be exposed to actinic radiation in an image-wise fashion and developed in an alkaline solution to develop the image created. In instances where the emulsion and process are used to make circuit boards, the metallic surface uncovered during developing is then etched away, leaving only the coated sections of the surface. The resulting coated surfaces will be the circuit traces of the circuit board.
Patent CA-2053460-A1 (CA)
Title: Analog waveform decoder
Inventor: JOSEPH EUGENE B
IPC: G06K7/00
Filed: 1991-10-15
Abstract: ABSTRACT OF THE DISCLOSURE    A method for decoding information contained in an analog waveform representative of a bar code symbol comprising the steps of identifying a decodable portion of an analog waveform; processing said decodable portion to obtain a plurality of waveform descriptors; and performing a high and low density decoding process to one or more of said plurality of waveform descriptors for decoding infor-mation contained in either a high or low density symbol respectively, is disclosed.  The high density decoder used for decoding high density symbols utilizes extrema extents, i.e., areas of the peaks and valleys of the analog waveform which directly correlate to the size of the bars/spaces of a high density bar code.  After locat-ing the seed point of the waveform, each extrema extent is generated and thresholded at each peak/valley location to decide its size.  The high density decoder is adaptive in that the thresholding extent value is updated as the solution grows away from the seed point.  The low density decoder used for decoding low density symbols utilizes the widths of the peaks/valleys for decoding purposes and utilizes a histogramming and backtracking technique for removing noise levels from the analog waveform.  Back-tracking allows another decode attempt to be made if one is unsuccessful.

Title: Semiconductor laser
Inventor: YOSHIDA ICHIRO
IPC: H01S5/30
Filed: 1992-06-11
Abstract: Abstract of the Disclosure A p-clad layer constituting the semiconductor laser device according to this invention includes an inner clad area near to an active layer, and an outer clad area remote from the active layer, the outer clad area having a narrower bandgap than that of the inner clad area, the thickness and the composition of the inner clad area being so set that beams do not substantially exude from the active layer to the outer clad area.  A multi-quantum barrier structure is provided between the active layer and the p-clad layer.          At least one of barrier layers of the multi-quantum barrier structure is formed of a material which applies tensile stress thereto, and at least one of well layers provided between one of the barrier layers and its adjacent one is formed of a material which applies contraction stress thereto, whereby an average lattice constant of the multi-quantum barrier agrees with that of a substrate.  The use of a material in the barrier layers allows the bandgap to be sufficiently wide.          Consequently even in comparatively high-temperature environments carriers, especially electrons, can be prevented from overflowing from the active layer to the clad layers, and no deterioration of the characteristics takes place.
