Abstract: A pavement marking tape has raised, irregular polygonal relief features with retroreflective elements covering a portion of the surface of the tape. The form of the relief features minimizes shadowing effects. Raised relief features are shaped to increase the visible number of vertical faces and edges of the relief features, which are the most reflective structures, and are oriented toward incident light from an approaching observer to maximize retroreflectivity.

Abstract: The disclosed technology relates to a high rise modular structure having a truss structure. The truss structure has four corner columns wherein the columns carrying the load of the building. The columns are adapted to have lifting arms for assembling the structure and plugs for snap fitting the modular units into one another. Once assembled, the modular units are tied to one another using a steel plate/blind rivet system. The modular structure is also capable of having an advanced weather protecting system for when the modular structure is on-site and not yet assembled.

Abstract: A paintball marker (10) comprises a barrel (11), through which paintballs may be fired by a firing mechanism (not shown). A handle (12) is provided to allow a user to comfortably grip the marker (10) and a trigger (13) is provided, for activating the firing mechanism. A trigger guard (14) is also provided to help prevent accidental activation of the firing mechanism. A hopper (15) is also provided for loading the marker (10) with one or more paintballs. The marker (10) with one or more paintballs . The marker (10) is fitted with a switching means (20) operative to switch the marker (10) between two modes, a live mode in which the firing mechanism can be activated and a safe mode in which the firing mechanism cannot be activated. The device is switched between said modes in response to signals received by a signals receiving means from a remote source.

Abstract: An electrophoretic display device (1) comprising one pixel (10) with an electrophoretic medium (13), electrodes (6, 7), as well as drive means (4) by which the pixels can be brought into different optical states. Some time (thold) after the application of an addressing pulse (Paddress) for setting the brightness level (Rw, Rb) of a pixel (10), a restore pulse voltage (Prestore) is applied between the electrodes (6,6?,7) for restoring the brightness level of a pixel to the set level (Rw, Rb). The restore pulse may be a set of consecutive pulses to bring the drifted brightness level even more smoothly (i.e. less perceivably) back to the original brightness level.
