Abstract: A dose counter includes a triggering unit having at least a first and a second trigger member thereon. The triggering unit is configured interact with the canister of a metered-dose inhaler when the canister moves in a longitudinal direction from a rest position to an activation position. A circuit assembly includes a substrate with at least a first and a second switch thereon. The first and second switches are configured to interact with the first and second trigger members when the canister moves from the rest position to the activation position. The circuit assembly includes a counting circuit that is configured to receive a signal from the first and second switches and to determine when the metered dose inhaler is activated.

Abstract: A rotatable projection system is provided. A mounting system for the projection system includes a support back and a rotatable mounting system mounted to the support back. The rotatable mounting system includes a first frame, a second frame mounted to the first frame in a fixed angular relationship, and a rotating joint mounted to at least one of the first frame and the second frame and to the support back to provide rotation of the rotatable mounting system relative to the support back. The rotatable projection system may further include a projector mounted to the first frame and a projection board mounted to the second frame. The projector may include a mirror positioned to reflect light from the projector onto the projection board.

Abstract: A device for mounting a whiteboard and a projector is provided. The device comprises a base and a pole mounted to the base such that the pole is substantially perpendicular to a surface. The base comprises a transport mechanism which allows the device to be moved from a first location on the surface to a second location on the surface. The pole comprises a first mounting bracket and a second mounting bracket. The first mounting bracket is for mounting a whiteboard such that an interactive surface of the whiteboard is capable of being positioned in a plane of a plurality of planes, including a receiving plane. The second mounting bracket is for mounting a projector such that the projector is capable of projecting onto the whiteboard while the interactive surface of the whiteboard is positioned in the receiving plane.

Abstract: A cutting tool having a retractable blade and capable of being guided using a user's finger. The cutting tool comprises a handle portion having at a first end thereof a first elongated support member, a second elongated support member, and an open region therebetween. A second end of the handle portion is operatively connected to a first end of a sleeve portion. A second end of the sleeve portion has a blade exposing region. A blade carriage is slidably disposed within the sleeve portion and along a longitudinal axis thereof, and a blade is operatively connected to the blade carriage. The blade carriage can move between an extended position and a retracted position along the longitudinal axis of the sleeve portion. When the blade carriage is in the extended position, the blade extends outside of the sleeve portion adjacent the blade exposing region.
