Abstract: A medical insertion device includes an introducer assembly, a needle, and a housing. The introducer assembly includes a dilator coaxially disposed in a sheath, the dilator removably engaged to the sheath in an insertion configuration. The needle is coaxially disposed in the dilator, the needle having a distal tip and a proximal end coupled to a needle hub. The housing may be removably engaged to the dilator. The needle hub is movably disposed in the housing between a first locked position, a second locked position, and a third locked position.

Abstract: A standalone virtual device driver that is not a mouse driver replacement or a mouse minidriver examines mouse data packets received from the mouse hardware for data packets that are obviously or likely to be faulty. When such a data packet is detected, the virtual device driver also removes the suspected faulty data by returning a null mouse packet to the mouse driver in its place. The virtual device driver may also initiate resynchronization procedures or reset the mouse hardware if necessary.

Abstract: An apparatus for the automatic adjustment of the inclination angle of a keyboard during use by an operator. The unit operates by a motorized camshaft raising and lowering the back end of a hinged platform that supports a computer keyboard or other input device. The rate of change of the inclination angle and the inclination height are adjustable by the operator. The apparatus is useful in the prevention or alleviation of the effects of repetitive motion disease or carpal tunnel syndrome.

Abstract: The apparatus includes an air temperature and humidity control chamber, a chopper room, strand choppers in the chopper room, a first controllable pitch fan having an inlet connected to the temperature and humidity control chamber and an outlet connected to the chopper room, a forming hood beneath the choppers, an endless conveyor chain beneath the forming hood, a chopped strand collecting chamber for collecting chopped strands which happen to pass through the conveyor chain, a suction chamber disposed beneath an upper flight of the conveyor chain and partitioned into a plurality of sections each having an inlet communicating with the forming hood through the conveyor chain and being provided with nozzle-forming downstream convergent baffle plates therein and an outlet communicating with the chopped strand collecting chamber through a duct having an adjustable damper therein securable in an adjusted position, a second controllable pitch fan having an inlet connected to the chopped strand collecting chamber and

Abstract: The strand guide device includes a generally vertical base plate, a pair of vertically spaced strand guide rolls secured to the base plate in cantilever fashion, and a generally vertical strand guide plate extending from the base plate parallel to and principally adjacent the upper one of the rolls and having a contoured upper edge defining a generally U-shaped strand guide portion adapted to confine moving strands and a slot portion inclined upwardly toward the strand guide portion and adapted to hold a stationary standby strand in readiness for insertion into a group of moving strands.

Abstract: Method of and apparatus for producing roving with a controlled number of strands including means for advancing a linear element along a given path; means for directing light to the element for reflection therefrom; means for sensing changes in the reflected light as an indication of changes in the speed of the elements advancement; means for supplying a signal in response to the changing reflected light; and means for controlling the advancement of the element in response to the signal.
