Comm Equip Makers Demand High Power Output & Small Footprint

Figure1. LTM4622(A) Can Be Mounted on the Underside of a PCB

Many communications systems are powered via a 48V backplane. This voltage is normally stepped down to a lower intermediate bus voltage, typically to either 12V, 5V or even lower, in order to power the racks of boards within the system. However, most of the sub-circuits or ICs on these boards are required to

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
