Integrated safety functions in the Sinumerik drive from Siemens meet the requirements of safety Category 3, compliance with EN 954-1, and are an integral part of the basic system. Additional sensors are not necessary, which reduces machine installation effort and results in a "slimline" control cabinet. The scope of functions supported includes system monitoring at speed and standstill, as well as functions for safe travel range limiting and range detection.
A multi-processor architecture forms a dual-channel, system structure, and safety functions are redundantly integrated in NC, drive and internal PLC. Process variables and safety-relevant system data are cross monitored. Safety functions are available in all operating modes and communicate with the process using input/output signals.

The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
