Abstract: A failsafe assembly for use with a thermostat that includes a housing that defines a housing interior, and first and second thermoswitches disposed in the housing interior. The first thermoswitch includes an open and a closed state and is normally in the open state. The first thermoswitch is configured to switch to the closed state when an ambient temperature drops below a predetermined lower threshold temperature and the first thermoswitch is configured to switch back to the open state when the ambient temperature rises above a predetermined first safety temperature. The second thermoswitch includes an open and a closed state and is normally in the open state. The second thermoswitch is configured to switch to the closed state when the ambient temperature exceeds a predetermined upper threshold temperature. The second thermoswitch is configured to switch back to the open state when the ambient temperature drops below a predetermined second safety temperature.

Abstract: A method including receiving a first image of a scene captured from a first perspective, the first image including an object and a background; segmenting the first image to extract a first two-dimensional contour of the object; approximating a plurality of three-dimensional locations of a plurality of points on the first contour; generating a three-dimensional billboard of the object based on the three-dimensional locations; and projecting the first image onto the three-dimensional billboard.

Abstract: A method used in broadcasts of events is disclosed for identifying the coordinates of an object in world space from a video frame, where the object is not on the geometric model of the environment. Once the world coordinates of the object are identified, a graphic may be added to a video replay showing the object. The method may also be expanded in a further embodiment to identify a trajectory of an object over time moving through world space from video images of the start and end of the trajectory, where the object is not on the geometric model of the environment. Once the trajectory of the object in world space is identified, a graphic may be added to a video replay showing the trajectory.

Abstract: A telestrator system is disclosed that allows a broadcaster to annotate video during or after an event. For example, while televising a sporting event, an announcer (or other user) can use the present invention to draw over the video of the event to highlight one or more actions, features, etc. In one embodiment, when the announcer draws over the video, it appears that the announcer is drawing on the field or location of the event. Such an appearance can be performed by mapping the pixels location from the user's drawing to three dimensional locations at the event. Other embodiments include drawing on the video without obscuring persons and/or other specified objects, and/or smoothing the drawings in real time.

Abstract: Maleic anhydride-grafted HDPE fibers are disclosed. The processing of LLDPE and fibers is enhanced by including HDPE or LLDPE which has been grafted with maleic anhydride to obtain succinic acid or anhydride groups along the linear polyethylene chain in the fiber feed stock. The fibers are formed by extruding molten LLDPE containing the grafted HDPE or LLDPE through an orifice to form a thin fluid stream, melt drawing the thin fluid stream, and quenching the melt drawn thin fluid stream to form a fine denier strand. Biconstituent fibers of LLDPE and grafted HDPE or LLDPE, mixtures of such fibers with other fibers such as polyester, and woven and non-woven fabrics made from such fibers and fiber blends are also discovered.
