Abstract: A foot pedal evacuates debris and fluid from the field of view of a camera during arthroscopic procedures. In a first embodiment, the foot pedal houses a ball check valve to control fluid flow, and includes a base and a foot support hingedly mounted to one another. The foot support includes a valve actuator that opens the ball check valve by distorting the shape of its valve seat. The ball check valve includes a pair of connectors at the ends of the valve adapted to accept irrigation tubing. The connectors are in axial alignment with one another in a first embodiment and in parallel relation to one another in a second embodiment. A third embodiment eliminates the ball check valve and a spring-loaded lever pinches a tube to prevent fluid flow. Depression of the foot support overcomes the bias of the spring so that liquid fluid flows through the tube.

Abstract: The present invention relates to a process for making a decorative device to be incorporated in jewelry or other objects that will likely be worn or carried by a person. The invention generally comprises the steps of removing a computer chip from a personal computer or other type of computing device and then removing from the computer chip substantially all of the metal connector elements used to mount the chip to a board, usually known as the “mother board.” Next, at least one of the two main faces of the computer chip, typically made of silicon or a graphite material, is grinded down so as to expose a plurality of the conductive pathways formed within the computer chip, whereupon the main face of the computer chip with the pathways exposed thereon may be polished.
