Abstract: The invention relates to portable dynamic display device, which may be used with for instance advertising using multimedia presentations. The device of the invention may be configured to be mounted on a human body and carried from place to place while displaying a video image and playing an audio track.

Abstract: An apparatus to prevent strip material from falling off the edges of a strip material package when unwinding. The package comprises a generally cylindrical and flangeless core around which the strip material is wound transversely in a plurality of overlapping layers. The apparatus also includes an idler roller. When unwinding, the strip material goes around the idler roller, then around the package, generally in its central portion and then again around the idler roller before being fed to a laminating machine. A method to use the apparatus is also provided.

Abstract: This invention refers to the traction lugs of reinforced elastomeric endless traction bands, and more particularly to those which are used on heavy vehicles like defense vehicles or for skid steer vehicles. More specifically, the invention relates to traction lugs which are angled with respect to the transversal axis of the traction band and preferably disposed in chevrons, which optimize the band's traction while reducing the occurrences of teeth skipping and the level of vibrations and noise induced by the interaction of the traction band with the sprocket.

Abstract: A method and system for the detection, notification and tracking of cargo theft proposes to install, inside cargo to be protected, a tracking device having communication and dead reckoning capabilities. As long as the tracking device senses that it is within a virtual fence generated by an access point, it lays dormant. When the tracking device senses that it is no longer within the virtual fence it activates the dead reckoning capabilities and communicates with a central server to supply dead reckoning data thereto. The central server processes this data and determines the current location of the cargo.

Abstract: A bandage cooling apparatus has a bandage, a container, a casing, a valve and an actuator. The bandage has a first temperature. The container contains a gaseous fluid and has an exit. The casing comprises a chamber which contains the bandage, an inlet and outlet which both defines passages from the chamber and through the casing. The outlet has a removable lid. The valve connects the inlet of the casing to the exit of the container. The actuator operates the valve whereby a portion of the gaseous fluid expands from the container into the chamber through the valve upon operation of the actuator such that the bandage gets to a second temperature which is different from the first temperature.

Abstract: This invention relates to an endless traction band that is used to propel snowmobiles and more particularly, to an improved ground-engaging side of the traction band, which helps reduce the noise and vibration levels during the operation of the snowmobile. The various protruding lug configurations defines a predetermined number of different lug profiles, from which the sequence of profiles on the endless band are generated in such a way so that every sequence of profiles is different from one another.

Abstract: This invention relates to the guide lugs of reinforced elastomeric endless traction bands, which are used on heavy vehicles like defence vehicles. More specifically, the invention relates to guide lugs which are partly nested into each other around the curved portion of the traction band in order to minimize de-tracking occurrences.

Abstract: This invention relates to an endless traction band that is used to propel tracked vehicles and, more particularly, to an improved traction band made from a polymer adapted to travel over a drive sprocket, a plurality of guide wheels and a tension wheel. The inner surface of the endless traction band includes a different lug configuration which allows for the endless traction band to be installed more efficiently on a tracked vehicle.

Abstract: An integrated exterior inlet/exhaust port for providing two air channels through a wall while only requiring a single hole through the wall.

Abstract: The endless track is made of a reinforced rubber material with longitudinally spaced and transversely disposed stiffeners embedded in the rubber material. The body defines a central band portion and opposite lateral band portions that are located on the sides of the central band portion. The central band portion is delimited from the two lateral band portions by two corresponding suspension bearing portions, each defining a plurality of clipping sites that are adapted to receive a metallic clip. The track is characterized in that the clips that are mounted in an arrangement of mixed clip sequences on each suspension bearing portion. Each [[c lip]] clip sequence comprises one or more successive clipping sites with clips immediately followed by one or two successive clipping sites without a clip. This arrangement of mixed clip sequences lowers the overall noise level generated by the track while rotating. It also lowers the overall weight of the track and the manufacturing costs thereof.

Abstract: This invention relates to endless tracks and systems used to propel tracked vehicles [i.e., vehicles which use endless tracks rather than tires to contact the terrain over which they are driven, e.g., tractors, tanks, bulldozers, etc.] and, more particularly, to an improved split wheel design and installation process therefore. The track is made from a polymer adapted to travel over a drive sprocket, a plurality of guide wheels and a tension wheel. A new step by step methodology allows the endless track to be installed and used more efficiently when the tension wheel or the drive sprocket is replaced by a split wheel.

Abstract: A compound selected from the group consisting of a compound of formula I a compound of formula II and when the compound of formula I and II comprises an amino group pharmaceutically acceptable ammonium salts thereof, wherein R1, R2, Cx, n, R3, R4, R5, Y are as defined in the specification.

Abstract: A winch assembly for the displacement of a person between a first vertical position and a second vertical position comprising: a winch for displacing a person in a harness between said first and second vertical positions; a first winch attachment means for realizably engaging said harness, said first winch attachment means being attached to said winch for the displacement of a person between said first and second vertical positions; and a second winch attachment means for realizably attaching the winch to an overhead support, the improvement wherein said first attachment means comprises two opposed support arms and displacement means associated with each said support arms whereby at least part of each arms is displaceable between a working extended position for engaging said harness and a non-working retracted position. The winch has a reduced or more compact aspect during non-working periods as well as in the case of a moving of the winch assembly during non-working periods.

Abstract: A compound selected from the group consisting of a compound of formula I a compound of formula II and when the compound of formula I and II comprises an amino group pharmaceutically acceptable ammonium salts thereof, wherein R1, R2, Cx, n, R3, R4, R5, Y are as defined in the specification.

Abstract: A compound of formula I and pharmaceutically acceptable derivatives thereof Cx, R1 and R2 being as defined in the disclosure may be used to inhibit the activity of HIV integrase.
