Linear Image Acquisition System
This is an electronic circuit with embedded software that can scan a moving video signal in real-time while eliminating pick-up redundancy. The system is currently in use for monitoring train traffic throughout North America. It uses a linear camera and incorporates many leading-edge features.

Synchronous Sampler for Four Cameras
This is an electronic interface that is placed between the cameras and a conventional videotape recorder.

The interface captures analog images (frames) from each camera, converts them into a digital format, processes them, and reconverts them to analog format for recording on the videotape.

Every image from a given camera is interlaced with those from the other cameras. The system thus captures the sweep of each camera 15 times per second, for example, instead of switching from one to another every quarter of a second. A system that handles images from four cameras, allocating two seconds to each, would lose six seconds of imagery for every scanning cycle.

With this system, it is also possible to reassemble and view the images produced by any one of the cameras. In addition, a serial port allows printing of any frame.

Video Recognition System
Initially developed for railways, this system consists of an electronic circuit and embedded software, and uses video recognition to determine the direction of a train, count its cars and determine its speed.

This is a sophisticated video recognition system that uses a spectral power-density processor to establish correlations based on fast Fourier transformations. The background landscape, different types of cars, weather conditions (snow or rain) and the time of day (sunlight level) do not affect recognition.

Specialized Video Converter for the CBC
Design of a device capable of extracting the teletext for the hearing impaired from the video image, tying it to an SmpTE time code in order to cross-index the text and the image.
