Abstract: A conferencing bridging technique for compressed information signals which monitors the signal energy transmitted by each conferee. When there is only one conferee speaking, the summing circuit in the bridge unit is bypassed along with the speech decoding/coding apparatus and the talking conferee's signal is broadcast to all conferees. If there is more than one conferee speaking at any given time, then only the speaking conferee's signals are routed to an associated speech decoder wherein those conferees' compressed signals are decompressed. These decompressed signals are then combined by the summing circuit and the sum is recompressed and broadcast to all conferees. Advantageously, the above-describedtechnique eliminates the signal degradation associated with tandeming of signal decoding and coding operations and permits the sharing of a smaller number of signal decoders among a larger number of conferees.

Abstract: A comparator circuit for a switched resistive network, which may be combined with a transconductance amplifier, simultaneously and independently compares a plurality of input voltages to a reference voltage. The circuit comprises a current splitter having a current input, a plurality of comparator outputs, and a corresponding plurality of voltage inputs that control the fraction of the input current available at each comparator output. A reference output of the current splitter is provided as an input to a current mirror, and each of the comparator outputs of the current splitter is connected to a corresponding output of the current mirror. The current available at each of the current mirror outputs is a function of the reference input provided from the current splitter. The comparator circuit needs only one bias input and one reference input. The inclusion of a second biasing device with an associated mirror device produces a transconductance amplifier combined with the comparator circuit. This combination minimizes the integrated circuit area required for transconductors and comparators on image processing chips.

Patent CA-2132756-A1 (CA)
Inventor: SIMARD PATRICE Y
IPC: G06N3/04
Filed: 1994-09-23
Abstract: Nodal outputs are discretized to values of S2n where n is an integer and S is equal to +1 or -1. During forward propagation, this offers the advantage offorming a product of a nodal output and a weight using a simple shift operation rather than a multiply operation. Replacing multiply operations with shift operations through out a neural network improves response times and permits building largernetworks that have broader applicability. Training is also improved by increasing the efficiency of backward propagation. The multiplications involved in backwardpropagation are reduced to shift operations by discretizing the errors associated with each node so that they are represented as S2n where n is an integer and S is equal to +1 or -1.

Title: Liquid crystal optical waveguide display system
Inventor: ROCKWELL MARSHALL A III
IPC: G09F13/18
Filed: 1992-08-03
Abstract: A controllable waveguide display based on a cladding (3), supercladding (1 and 6) and/or core (4) utilizing liquid crystals is described. An electric field applied through a fiber causes the liquid crystal layer to become aligned. Changes in the refractive index of the liquid crystal layer causes light to switch out of the fiber. In one embodiment light is coupled into a supercladding (6) running alongside the core and reflected out of the fiber at a reflector pit (35) cut in the fiber. Parallel arrays of fibers are used to cover a substrate and make large viewing screens. A  tapered supercladding (6) helps improve the contrast ratio of screens using fiber taps. A thin cladding (3) and closely spaced dark cladding (2) also help improve the screen contrast ratio. Color techniques based on a three core fiber that shares a single supercladding (1) is introduced. An illumination method is also taught which breaks white light into colored components (73) with dielectrc filters (103) to efficiently utilize white light (102). An electronic feedback system (96) is introduced which provides screen brightness and color uniformity under varying temperature and environmental conditions.

Patent CA-2147252-A1 (CA)
Title: Rna packaging system
Inventor: WILSON THOMAS M A
IPC: C12N1/21
Filed: 1993-10-28
Abstract: The present invention relates to an in vivo system for expression and packaging of recombinant RNA into pseudovirus par-ticles. The invention is based on the discovery that plant viral coat proteins (CPs) may be efficiently expressed in E. coli, and that these recombinant coat proteins will function to assemble in vivo and package recombinant chimeric RNA, containing an opera-tively linked origin-of-assembly (OAS) sequence, to form mature viral particles containing a foreign RNA. The present invention thus provides for packaging of RNA into a ribonuclease-resistant form that is easily purified and stored, and which overcomes the prior art problems associated with degradation of RNA by ribonucleases. Significantly, the method of the invention is RNA sequence- and length-independent. The components of the invention include a source in the bacterial host of viral coat proteins, and a source in the bacterial host to direct the transcription of a DNA molecule comprising an OAS-encoding DNA and a for-eign DNA, which DNA molecule can be transcribed in the host cell to produce an RNA molecule comprising an OAS operative-ly linked to an RNA of interest. The CPs and OAS are from a plant virus having a rod-shaped helical particle and a single-stranded RNA genome, most preferably tobacco mosaic virus.
