Linear Technology has introduced the LTC4265, an 802.3af/802.3at-compliant Power over Ethernet interface controller for high-power powered device (PD) applications needing up to 25.5 W. A new IEEE 802.3at definition, also known as the PoE+ standard, has expanded the power budget and improves the classification mechanism used by power sourcing equipment and PDs to identify each other.
Sun Microsystems has announced the SPARC Enterprise T5440 server, claimed to be the first to deliver the scalability and reliability of traditional midrange systems with the performance and energy efficiency of the UltraSPARC T2 Plus architecture.
The Industrial Automation Group of Advantech Australia has introduced the EKI-1351 (1-port) and EKI-1352 (2-port) 802.11b/g device servers. The models allow RS232/422/485 serial devices to be remotely monitored, managed and controlled wirelessly.
Researchers in China and Britain have made a type of nanometre-sized rotor with an off-centre axis of rotation.
Engineers at Samsung in Korea have synthesised copper nanoparticles for use in inkjet-printed electronics.
Heim Systems has developed a flexible, compact distributed data acquisition system, DATaRec 4, that consists of interface modules that can be positioned up to 10 m from each other, or mechanically linked to make a compact acquisition unit.
The data logger has been around for hundreds of years, evolving from an assistant with paper and pencil to the technology-packed, automated products that they can be today. Much like hammers are tools to carpenters, data loggers are tools to scientists, engineers and anyone else working in a measurement environment.
