TwinBlade reduces operating and maintenance costs because wear from abrasive dust loads doesn't increase energy consumption over time.
Blade erosion in flue gas axial fans increases operating costs due to reduced fan efficiency. Positioning two non-profiled blades on one common blade base, says Håkan Bard, head of development at ABB Ventilation Products, results in substantially less wear than the corresponding airfoil blade. Even with some wear developing at the leading edge, fan peak efficiency is unaffected. In addition to fewer components, the "PF TwinBlade" promises no increase in power consumption due to wear, low impeller inertia, and less blade bearing/linkage maintenance.

Unlike industrial robots, which suffered a slight overall slump in 2012, service robots continue to be increasingly in demand. The majority are used for defense, such as unmanned aerial vehicles (UAVs); and agriculture, such as milking robots.
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
Design News and Digi-Key presents: Creating & Testing Your First RTOS Application Using MQX, a crash course that will look at defining a project, selecting a target processor, blocking code, defining tasks, completing code, and debugging.
These are the toys that inspired budding engineers to try out sublime designs, create miniature structures, and experiment with bizarre contraptions using sets that could be torn down and reconstructed over and over.
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.
