Combining MEMS accelerometers with MicroStrain’s award-winning Micro Datalogging Transceiver systems, G-Link® is a high speed, triaxial accelerometer node, designed to operate as part of an integrated wireless sensor network system.

Featuring 2 KHz sweep rates, combined with 2 Mbytes of flash memory, these little nodes pack a lot of power in a small package. Every node in the wireless network is assigned a unique 16 bit address, so a single host transceiver can address thousands of multichannel sensor nodes.

The bi-directional RF communications link can trigger a sample to be logged from 70 meters, or request real-time data to be transmitted to the host PC for data acquisition/analysis. The frequency agile system enables simultaneous real-time streaming from up to 16 nodes in the 2.4 GHz range.

Available in 2g or 10g range, these small, fast, wireless accelerometers can be used to monitor tilt and vibration in a wide range of machines and structures.

A Software Development Kit is available, which includes fullycommented source code and a compiled executable for Microsoft® Visual Studio C++ .NET 7.1, Microsoft® VB 6.0, Microsoft® VB.NET 2003, Microsoft® VB.NET 2005 and LabVIEW® 7.1.

Maxim Integrated Products (NASDAQ: MXIM) introduces its /PR family of ruggedized, plastic-encapsulated devices for high-reliability military and aerospace applications. Designed and fabricated for applications that demand high-temperature performance and enhanced reliability, /PR devices are 100% burned-in for 120 hours at +135°C and tri-temp tested at military temperatures. Additionally, for military and aerospace applications, these /PR products have the traditional Sn/Pb finish. These devices thus provide cost-effective solutions for electrically stressful environments, such as mobile military and aerospace systems.

“We are in the process of releasing a variety of these enhanced devices that go beyond Maxim’s conventional plastic parts,” said John O’Boyle, Military Business Manager at Maxim. “Offered in ruggedized SO packages, /PR devices are tailored for applications requiring more than normal reliability with the added benefit of operation at extended temperature ranges.

“These parts meet customer needs for military-grade parts in a more cost-effective offering,” continued O’Boyle. “We plan on providing a broad portfolio of devices in this reliable, plastic option.”

Maxim’s /PR portfolio includes the following devices:

• DG408/DG409 8-channel/dual 4-channel, CMOS analog multiplexers
