Stemmer Enhances Common Vision Blox

Stemmer Imaging has announced Version 10.1 of the Common Vision Blox (CVB) programming library. New tools in Version 10.1 include CVB GigE Vision Server for standardised remote imaging, CVB Match 3D for demanding 3D surface inspection and the CVB GPU Processing tool, which offers image processing acceleration.

CVB GigE Vision Server allows a suitably equipped computer to be used as both an image receiver and as an image source. It acts like a GigE Vision compliant image source with configurable features. CVB GigE Vision Server opens up a range of opportunities including full application remote control, distributed pre-processing and computing, or multicast transfers to multiple monitoring stations.

CVB Match 3D offers a practical approach for 3D imaging, providing high accuracy and a processing speed fast enough to keep track with modern production lines. The 3D image of a perfect sample (golden template) is compared to the 3D images of upcoming test parts in the production line, complete with full alignment of the two images. Differences between the images of the template and the object highlight part deviations and can be identified in real time, allowing pass/fail decisions to be made.

The CVB GPU Processing tool enables the power of the computer's graphic processing unit to be used for image processing applications. Since CVB already supports multiple processors using multiple cores it is now possible to extend this to the fastest processor in the computer. Image data can be transferred to the GPU memory, passed through one of the GPU's hardware arithmetic logical units for pre-processing purposes and then transferred back to host memory for further post-processing.

Pre-processing includes filtering, frame averaging and Bayer conversion. CVB Version 10.1 is available for download and is free of charge for registered users of Common Vision Blox. All documentation, samples and components are included. A free 14-day trial version for all components is also available for feasibility and performance tests.

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as

EGCS-D0 Accelerometer Now Available in 10,000g Range

Measurement Specialties, Inc. (NASDAQ: MEAS) has recently redesigned the EGCS-D0 accelerometer to enable it to accurately and reliably measure up to ±10,000g. This rugged device is critically damped, which is the ideal mechanism to protect the accelerometer against ±20,000g impacts and prevent sensor ringing. The EGCS-D0 accelerometer is now available in ranges from ±5g to ±10,000g which makes it ideal for both critical low-g measurements and high-g impacts. These units feature a Wheatstone Bridge mV output with a standard compensated temperature range of 20ºC to 80ºC (other options available). The EGCS-D0 was specifically designed for impact and shock testing in auto safety, aerospace, military and civil engineering applications. Designed to be bolt-mounted, this device operates from 2-15Vdc excitation with electrical output ratiometric to voltage input. Optional triaxial mounting blocks (MTG-F4), signal conditioners (Model 101) and auto-zero inline amplifiers (Model 140) are avai

Ilix Cermet Reamers Are Ideal For Dry Machining Engineers Cutting Tools, the UK agent for Ilix, has introduced Ilix solid-carbide and cermet reamers for the machining of hard metals. The machine reamers 6372C and 6323 allow the production of high-precision holes with good surface finish. Compared with HSS, the solid-carbide qualities enable the increase of cutting parameters and tool life. The quality of the reamers is said to guarantee high performance, even for hard metals with a resistance more than 1200N/mm2. The Ilix carbide 6372C range of hundredth reamers is from 0.98mm through to 12.05mm in increments of 0.01mm. The reamers are manufactured to a tolerance of +0.000 - +0.004mm. The cermet reamers 6323 have new cutting geometry developed by Ilix. These reamers are said to be ideal for steel machining, having high chemical stability during the cutting process. They offer good wear resistance due to the high hardness and have low material adhesion. The Ilix cermet reamer is said to
