The device facilitates the fabrication of ME laminate configuration by using a flextensional cymbal located between two terfenol-D plates. A giant magnetoelectric effect in a heterostructure is achieved by clamping an ME terfenol-D alloy actuator and a cymbal-type piezoelectric single crystal-brass .....

Speed sensors are customarily used to detect the speed of power electronic driven motors, but that speed sensors could render the motor drive system unreliable. However, there are very few detection devices other than speed sensors that can generate readings when the motor drives are in a resting mo.....

A surface absorption modifier is developed to treat highly absorbent aggregates, and this patent concerns the application process of the surface modifier. Traditionally, aggregates such as sand and gravels are used to produce concrete but the decrease in granite supply leads to the application of re.....
