ABSTRACT:
Stopwatch precision enhancement device. The device includes an attachment means, a fluid-actuated, spring-return plunger mechanism, a fluid-filled, flexible, hose, and a thumb plunger mechanism mounted onto a two finger ring. The device facilitates ipsilateral hand stopwatch button depression by connecting any digit via a fluid-filled flexible, hose connecting simultaneously to a fluid-actuated, spring-return plunger mechanism and a thumb plunger mechanism mounted onto a two finger ring.
The thumb plunger is situated in the region of the proximal interphalangeal joint of the second digit such that the ipsilateral thumb is positioned to readily depress it, marking intervals of time as desired by the user.
