Sensor adds ID tools Tools that can read 1-D barcodes and 2-D data- matrix codes have been added to the company's In-Sight 2000 Vision Sensor. These tools support common 1-D codes such as ECC200 2-D data matrix and interleaved 2-of-5, Code 3-of-9, and Code 128 barcodes and read as many as 50 codes/s. They also can read low-contrast and poorly formed codes, as well as marking techniques such as dot-peen marking and laser etching. The sensor monitors the quality of 2-D marks by reading and feeding back information on how well a peen marker is performing for possible replacement. No programming is needed. Basic spreadsheet functions are used to set up 1-D applications. Drop-down menus enable users to select code type and set parameters for code quality, part-surface characteristics, and line speed.

Software increases precision Package Tool machine-vision software increases the speed, flexibility, and precision of automated package inspection. It suits the inspection of integrity, seal, label position, text, colors, and graphics on containers, cartons, and cellophane wrappers. Running on the company's Passport DSL digital vision system, the software can inspect thousands of parts per minute. Setups are done with the program-manager graphical user interface. Multiple templates within the same region of interest (ROI) allow the programming of up to eight inspection tasks. Polygonal ROIs align the tool so that only the desired features of a container are inspected. Run-time morphology cleans and enhances an image before comparison to the template. Package tool retrain permits the automatic creation of new templates using a single button. PPT VISION, Minneapolis, MN 55344; (952) 996-9500.
