Smart board acts as a system
Neuro-Sight Embedded 3 x 4-in. board is a self-contained system that can acquire video images, recognize known objects in the images, and output the results. It comes with a color CMOS sensor, ZISC-based neural network for pattern learning and recognition, a 150k-gate FPGA for programming vision applications, a 4-Mbit Flash EPROM, and two 512k x 8-bit SRAMs. Key features include 352 x 288-pixel resolution, network of 156 neurons, memory bank, RS-232 connector, and 24 I/O lines. The board integrates into a stand-alone smart camera, but it can be interfaced to a PC serial or parallel port for configuring the FPGA and loading a recognition engine into the neural network. The FPGA can be programmed to perform image acquisition control, on-the-fly pixel processing, feature extractions, and communications with the neural network and the I/O lines.

Software helps sensors
CapInspect and LabelInspect package inspection software support the company's In-Sight vision sensors. They target inspection tasks in the food, beverage, and pharmaceutical industries. CapInspect checks container caps for, skew, height, presence/absence, and container fill level. LabelInspect checks package labels for presence/absence, measures label position, and verifies logos, decorations, and other label features. Show-and-Go graphical user interface, common to all applications, enables users to train package features by drawing a box around the area to be inspected and clicking a toolbar button. Menu-driven wizards guide users step by step by setting up all aspects of the application. In production mode, users can view a live image display of inspections as they occur with running pass/fail results and statistical process information. Library of general-purpose In-Sight vision tools is available. Cognex Corp., Natick, MA 01760; (508) 650-3000.
