This research has broken through the limitations of traditional rehabilitation robot control methods, which often rely on fixed or variable impedance control with no consideration for the patient's ...

Owing to diffraction effects, waves diverge when propagating in a homogeneous medium. However, in practical applications, omnidirectional radiation is not always welcomed. Controlling and modulating ...

This video presents a unified hybrid force-impedance framework for highly dynamic end-effector motions. The unified framework features compliant behavior in the free (motion) task directions and ...

How do we succeed in performing mechanically unstable tasks? One way would be to stabilize the arm by means of feedback control. However, neural feedback, whether operating through involuntary (reflex ...

Schweitzer Engineering Laboratories, Inc. has released high-impedance fault detection in the SEL-651R Advanced Recloser Control. SEL’s patented Arc Sense technology (AST) detects more high-impedance ...

When used with other blocks and modules, a new approach to modeling operational-amplifier output impedance behavior can provide a more realistic overall behavioral model. Simulating the behavior of a ...

Signals carried by PCB traces longer than 1/10 of the critical length should be regarded as high speed signals High speed signals are not necessary signals of high frequency, but rather signal with ...

Any discussion of power integrity includes a great deal of emphasis on the concept of target impedance and flat impedance requirements. But how do we design a voltage regulator module (VRM) ...
