In Brief

Texas Instruments has developed a range of 32-bit digital signal processors which, it claims, offer the industry`s highest PWM resolution. The devices, optimized for motor control, digital power conversion and intelligent sensor controls, provide a 150 picosecond resolution - said to be 64 times more precise than any competing processor. They can deliver 16-bit accuracy in 100kHz control loops, and 12-bit at 1.5MHz, resulting in faster transient responses with lower ripple amplitudes.

• Rittal claims it is the first enclosure supplier to offer enclosure cooling systems with a "nanotechnology" coating, which repels oil and dust and prevents particles from attaching to the condensers. The performance of standard cooling systems can drop by 30-50% over time as the cooling membranes get dirty. Site trials of the new coating have shown that it cuts contamination, maintains cooling efficiency, simplifies cleaning and reduces servicing.

• Westermo Data Communications has formed a strategic partnership with the wireless connectivity specialist Wyless to deliver GPRS- and GSM-based communications for remote applications. The partners will offer robust, easy-to-manage industrial networking and temporary or remote communications anywhere in the UK with GSM/GPRS coverage.

The Danish integrated motor manufacturer JVL Industri Elektronik has made 2D and 3D drawings of its MAC 800 integrated servo motors available for download from its Web site. The drawings are available in the DXF, IGES and STEP formats. Drawings of other JVL products will be added to the site..

• Hitachi WirelessInfo Venture, a division of Hitachi set up last year, is working with the Ember Corporation to develop a family of ZigBee-based wireless sensors for monitoring, sensing and control applications. The sensors will be based on an Ember technology that integrates programmable microprocessors, an RF radio, memory and a network protocol stack on one tiny chip..
