The PROFIBUS Trade Organization (PTO) now offers a PROFInet real-time extension for general automation applications. Based on Ethernet, PROFInet is a modern standard for distributed automation standards that integrates existing fieldbus systems, specifically PROFIBUS. The new extension is called Soft Real Time, which features cycle times of 5 to 10 msec. It is compatible with the TCP/IP Ethernet protocol. In addition, a second PROFInet real-time extension is being developed, and is scheduled to be available in 2005 for high-performance motion control applications.

Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
