Barcode reader squeaks

DataMouse hand-held barcode reader detects two-dimensional data-matrix codes on high-contrast labels and directly applied marks, including dot-peened, on a range of surfaces, such as steels, alloys, titanium, rubbers, plastics, and polished cylindrical parts, regardless of background color and texture. Audible 'squeak' indicates a completed code reading. The reader uses a CCD progressive-scan imaging sensor, a white light, and the company's Medusa software. USB interface sends nearly real-time images to a Windows-based GUI. Read data also can be transferred into Excel or Access.

VisionPro release 3.3 PC-based machine-vision systems incorporate new vision software tools to its array of machine-vision software to reduce setup time, improve process yield, and expand pattern training. Synthetic PatMax tool provides new options for training PatMax functions. It can generate reference models without relying on image data and import CAD (DXF) data, extract edges, or sketch free hand to create reference models. Using PatMax, the PatInspect defect-detection tool can determine differences in the object compared to a trained image. It ignores acceptable variations in appearance to avoid false rejects due to part rotation, scale changes, and lighting variations.
