Abstract: The invention is directed to a cover for use with a portable display device. The cover has a lid which is rotatable between a closed position, through intermediate open positions, to a completely open position. A movable hinge is attached to the lid, such that the lid can rotate about the movable hinge. A fixed hinge is secured to a main body of the portable display device. The movable hinge is mounted to the fixed hinge to allow the movable hinge to be moved in an arcuate motion about the fixed hinge. Positive stop members are provided on the movable hinge and fixed hinge, whereby as the lid is rotated, the positive stop members define the intermediate open positions which position the lid at an angle relative to the main body, thereby allowing the lid to act as a stand for the portable display device. A connecting arm extends between and is pivotally mounted to the movable hinge and the fixed hinge.

Abstract: A safety intravenous catheter assembly is provided by interconnecting a safety receptacle for a retractable intravenous needle with a catheter that carries the needle and is advancible into a vein punctured by the needle. A coupling that is removably fastened to the catheter has an elongate stem portion that extends backwardly into the safety receptacle past a needle-stopping member within such receptacle. Such needle-stopping member is active to normally prevent backward movement of the needle into the receptacle.
