Abstract: A cello stand system for holding a cello that includes a base; a first and second arm, where each arm comprises at least one cello engagement region on an inner-side of the arm; where each arm is attached in an upright orientation along the length of the base; and where the inner-sides of the first and second arms and a top surface of the base define a cello holding cavity. The cello stand system functions to engage with a cello across a rib of the upper or lower bout to hold a cello on its side in a horizontal position.

Abstract: An edge-gripping wafer handling apparatus for holding and transporting wafers in a clean room environment is implemented by mounting gripping fingers on a paddle arm adapted to be controlled by a robot. At the free end of the paddle arm, a plurality of fixed fingers is mounted. Each of these fixed fingers includes a notch for gripping the edge of a wafer. A moving finger is mounted close to the fixed end of the paddle arm. The moving finger can be smoothly moved to engage the edge of the wafer and cause the opposite edge of the wafer to engage the fixed fingers. The movement of the moving finger is caused by a bellows flexing a hinge connected to the finger. The flexing hinge is formed as a parallelogram of two stable ends and two flexing arms. The movement of the hinge is smooth and causes no particulate matter to be generated due to rubbing or other friction generating mechanism.
