Wherever Pressure is Measured, Setra Has the Solution ...
Whether you're an end-user or OEM, Setra has a solution that will fit your application as well as your budget. Setra's industrial pressure transducers accurately measure pressure (hydraulic and pneumatic); liquids, gases, coolants, fuels, lubricants, refrigerants; and most other media. Pressure ranges extend from high to very low pressure for gauge, absolute, differential, and barometric pressures and vacuum.

Servo motion control accelerates throughput of plastic joining machines
An English company called Phasa has enhanced the performance of its specialist plastic component joining machines with high-performance new versions employing a key servo-based motion control system in place of a pneumatic actuator. The servo enables several seconds to be shaved off the assembly time of complex car door panels, increasing productivity significantly.

Sound lab pushes boundaries of audio realism
In his laboratory tucked into the basement of Princeton University's Von Neumann Hall, Edgar Choueiri creates illusions with sound. In a three-year effort with support from Sony, his team will seek to push the boundaries of sound reproduction and create a sound space so realistic that it can be used as a basis for virtual reality.

Drive-by-tongue system improved with retainer-like remodel

Tongue Drive is a wireless device that enables people with high-level spinal cord injuries to operate a computer and maneuver an electrically powered wheelchair simply by moving their tongues. In a major revamp, the newest prototype allows users to wear a dental retainer embedded with sensors to control the system.

Mike Likes:
Simotion D motion controllers get even better

The new generation of Simotion D445-2 multi-axis controllers from Siemens Industry features onboard Profinet interfaces and high-speed I/O. With three times the performance of its predecessor, a single controller can support up to 128 axes of motion. Simotion D motion control systems are the ideal solution for production machines covering all levels of performance – from simple single-axis positioning tasks to complex synchronous applications – with extremely short cycle times on a large numbers of axes.

Engineer’s Toolbox:
Torque gun optimized with configurable components

An innovative “rolling-resistance” measurement device and smart PC-based software provide users with accurate and consistent torque optimization of geared assemblies such as transmissions, gear boxes, and pumps.

Videos+: Technologies and inspiration in action
Measuring mobile-device battery capacity accurately
Battery manufacturers specify battery capacity using a standard current drain level. This is likely to be different than the capacity you will achieve with the average current drain of your mobile device. Testing the battery using repeatable discharge currents similar to your device is essential to predicting actual achievable battery capacity and run time. Agilent Technologies provides a one-box solution for device developers that provides precise, repeatable current loads and an integrated voltage and current measurement system.

NASA aims to harpoon comet to collect samples
Ever wonder how we might grab some comet core rocks and bring them back to Earth? Well the Comet Nucleus Sample Return mission will do just that by firing an explosive-powered, sample-collecting harpoon into a comet's heart and then bringing the debris back to the Big Blue Marble. How exactly will that play out? Watch and see. NASA engineers are testing the proof-of-concept, cross-bow launch system right now.
