Smart Card Based Lineman Safety
Abstract: As maintenance workers and electrical substations are being repaired, there are more electrical mishaps involving linemen today. Contact with overheated wires is the most frequent reason for electric shock and electrocution in the workplace, but there are other factors as well. When transporting equipment like poles and ladders, this happens when people underestimate the height of the ground and overhead wires. Not separating electrical supply is another common cause of …

Develop a System to Control a Prosthetic Hand by Using EMG
Abstract: An EMG-controlled prosthetic hand is a type of artificial hand that users can control through muscle signals. When a person with a missing hand tries to move their "phantom" hand, the muscles in the remaining part of the arm still produce electrical signals. Small sensors placed on the skin detect these signals, which are then translated into movements of the prosthetic hand, like opening, closing, or gripping objects. This technology …
