    Figure 1: Gate driver circuit diagram with a Bourns transformer

    While gate driver-based converters deliver improved efficiency, speed and signal integrity, their high frequency switching features can produce elevated levels of conducted electromagnetic interference (EMI), posing challenges to electromagnetic compatibility (EMC) and overall system reliability. To solve this

    Figure 1: Southampton hands. Across each palm can be seen a dc motor with a worm and wheel to rotate the thumb. Five other motors flex and extend the fingers and thumb. The fingertips have touch (force), slip/texture, and temperature sensors.

    For an upper extremity amputee, mass is a main factor when choosing an artificial hand. A hand should be lightweight so that high pressure points do not develop inside the plastic socket that attaches
