Higher Performance With Lower Fuel Consumption
A newly developed miniaturized electronic fuel injection (EFI) system designed especially for small combustion engines now provides the benefits of fuel injection, long enjoyed in larger engines, for small unmanned aerial vehicles (UAVs). The most striking characteristics of this system are higher performance combined with reduced consumption and considerably increased reliability. Microdrives are used to power the fuel pump to ensure the correct pressure in the fuel system.

Mike Likes:
Smart sensor is all torque, all the time

The new TorqSense RWT410/420 torque sensors with integral electronics from Saelig, which replace the RWT310/320 series, feature significant performance gains in resolution, frequency response, reduced sensor current consumption, and faster digital data throughput. Transducer overload capability has also been increased to 300%. The series offers a cost-effective, non-contact digital rotary torque measurement solution, using TorqSense Surface Acoustic Wave technology, suitable for torque monitoring, testing, or controlling drive mechanisms.

Unit and hardness converter iPhone app

Sealing specialist Trelleborg's iPhone app "Unit and Hardness Converter" surpassed 100,000 downloads in just the first five months of its release. This app helps you convert frequently used, basic engineering units and even worldwide currencies in an efficient and convenient way. It comes with a hardness converter based on ISO and ASTM standards to quickly switch between popular hardness scales for various material types. The app can be used in a wide range of design situations, whether related to sealing or not. No charge. Available from iTunes or Apple App Store ("Trelleborg Converter").

Enable Internet of Things via simple serial connection
Design engineers can easily add Wi-Fi connectivity to their products using new Microchip Technology Wi-Fi modules based on Roving Networks technology. These solutions use a simple serial interface to connect with any PIC microcontroller, and expand Microchip's wireless portfolio with the industry's lowest power consumption along with an integrated TCP/IP stack in a certified Wi-Fi solution. The Wi-Fi modules support all of Microchip's 8-, 16-, and 32-bit PIC microcontrollers.

Reduce compressed air consumption up to 97%
FIPA ejectors with air-saving function save energy without compromising cycle times. Equipped with automatic pressure regulation, EKPP, EKP, and EMM series ejectors can reduce compressed air usage by up to 50% per workpiece, regardless of its porosity, and save up to 97% for airtight workpieces. These ejectors never use more than a very low 50.8 psi, regardless of the actual feed pressure.

Ultra-compact Mini-Mag stages
Mini-MAG (MMG) precision linear positioning stages from Dover are now available with a complete and optimized controls package. OEMs and end users can combine an MMG linear motor stage with a compact Dover board-level, single-axis servo drive for easy integration into a control cabinet. Or try integrating a stage with a Kollmorgen AKD servo drive for single- or multi-axis applications and get real-time performance feedback. Both options provide Ethernet communication for fast data acquisition. Downloadable CAD files are available from for easy integration into customer models.
