Munich, Germany--Electric motors have undergone more change in the last ten years than the previous hundred. This is particularly true with ac induction motors. For example, users today can specify vector or inverter drives, as well as the convergence of both systems: sensorless vector control. Other emerging technologies include soft switching techniques and transient-resistant windings.
Computer models take over. Sensorless vector control blurs the distinction between inverter and vector drives. While open-loop inverters are relatively inexpensive, there is no method of feedback from the motor to allow
The DDV-IP is a two-wheeled self-balancing robot that can deliver cold beverages to thirsty folks on hot summer days. A wireless RF remote enables manual control of the device beyond the act of self-balancing. All of the features of the DDV-IP result in an effective delivery vehicle while providing entertainment to the user.
Eric Doster of iFixit talks about the most surprising aspect of the Microsoft Surface Pro 3 teardown. In a presentation at Medical Design & Manufacturing Midwest, iFixit gave the Surface Pro 3 a score of one (out of a possible 10) for repairability.
Barnacles and mussels stay attached to ship hulls and rocks because of a very sticky protein glue they secrete, holding on for a long time even underwater. Researchers at MIT took mussel glue as inspiration -- and as an ingredient -- for engineering their own sticky waterproof adhesive.
