The Wadsworth Electric Manufacturing Company was formed by George B. and Harry Wadsworth in 1904. George received his first patent for an electrical service entrance safety switch in 1907. This device reduced the likelihood of accident or fire and enabled homeowners to replace their own fuses. He received an additional 15 patents in the field ...
The tip of the vaulting pole is angled higher than eye level until three paces from takeoff, when the pole tip descends efficiently, amplifying run speed as the pole is planted into the vault box. The faster the vaulter can run and the more efficient their take-off is, the greater the kinetic energy that can be achieved and used during the vault.
An arc-fault circuit interrupter (AFCI) or arc-fault detection device (AFDD) [1] is a circuit breaker that breaks the circuit when it detects the electric arcs that are a signature of loose connections in home wiring. Loose connections, which can develop over time, can sometimes become hot enough to ignite house fires.

Vaulting throughout his career with a bamboo pole, Warmerdam was the first vaulter to clear 15 feet (4.57 m), accomplishing that feat at UC Berkeley on April 13, 1940. However, that achievement was not ratified for a world record, and his later vault of 4.60 m on June 29, 1940, was the first ratified jump over 15 feet.
The Division II pole vault national champion knew from others’ horror stories that a dwindling number of airlines were still willing to carry poles and that they were too long and cumbersome to ...
Vacuum interrupter with ceramic housing. In electrical engineering, a vacuum interrupter is a switch which uses electrical contacts in a vacuum. It is the core component of medium-voltage circuit-breakers, generator circuit-breakers, and high-voltage circuit-breakers.
