A newly patented invention avoids the cumbersome procedure of "fine tuning" electric motors. At NASA's Marshall Space Flight Center, Ann M. Casper designed a brushless dc motor that dynamically times the commutation between the rotor and stator--without disassembling its housing. She put Hall-effect sensors on the commutation board to provide feedback on the rotor position. A tool inserted into the endcap, while the motor runs, "tunes" the motor for maximum operating efficiency. invention received United States Patent 5654599.
The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
