Abstract: A speculum is provided, comprising two or more blades moveable between an open and a closed position. A polyisoprene or silicone tubular sheath is attached to at least one of the blades, the sheath being arranged to retain the lateral walls of the body cavity when the blades are in the open position. Sheath attachment means provided on one of the speculum blades facilitate attachment of the sheath to the blade, the attachment means comprising at least one patch or strip of adhesive material extending in a longitudinal direction of the blade.

Abstract: A method, graphical user interface, and computer program product on a computer readable medium are disclosed for presenting a user with a display of a skew clock tree for a digital circuit design. In the preferred embodiment, a computer system receives timing analysis data for a digital circuit. The computer system determines a propagation time delay between a first clock root and each of a plurality of clock sinks of the digital circuit associated with the first clock root based on the timing analysis data. The computer system then displays the first clock root and each clock sink associated with the first clock root of the skew clock tree along an axis representing time delay. In the displayed skew clock tree, each clock sink is positioned along the axis relative to the first clock root based on each clock sink's determined propagation time delay.
