Abstract: The present invention is directed to an air purifying escape hood that protects a user from acute environmental hazards by filtering contaminants and providing breathable air for a time sufficient to escape the hazard. The air purifying escape hood comprises a hood assembly that covers the head of the user and a filter assembly that filters contaminants and provides a flow of purified air to a user. The air purifying escape hood is particularly useful in protecting a user from smoke, allowing the user to safely escape a burning building and is further useful for protection against non-smoke related particulates, chemical and biological contaminants, and radiological/nuclear contaminants.

In preferred embodiments, the input device accommodates either a user's left or right hand, and in either case, positions the hand in an ergonomically desirable position. In another embodiment, the length of the input device of the present invention is adjusted for the size of the user's hand. In further embodiments, the input device of the present invention provides a palm rest. Other desirable features included in preferred embodiments include lateral buttons that are positioned one above the other.

Abstract: Disclosed is a stand for a laptop computer or other data display device, wherein the display portion, or monitor, projects upwardly from the data display container. The user can adjust the position of the portable data display container so as to position the top edge of the monitor at the same height as the user's eyes. This position permits the user to maintain better posture when using the data display device. Additionally, the stand of the present invention may provide a rack for restraining cables attached to the data display device. The stand may also have a swivel so that the monitor can be viewed from whatever angle is convenient for the user. Desirably, the stand also includes a document holder and provides an anchor for a security cable.
