    摘要： A projector with automatic focusing assistance includes a focus control for controlling the focus of optics of the projector, and a focus control use sensor. The projector automatically displays a focus assistance element when the focus control use sensor detects use of the focus control. A method of operating a projector includes automatically displaying a focus assistance element when a focus control of the projector is used.

    摘要： A method for projecting an image with a projection system includes zooming a projected image in accordance with a resolution of the image, when a resolution of the image is less than a resolution corresponding to the projection system. A projection system for projecting an image based on a received video signal including optics having a corresponding resolution and a zoom control controlling a zoom of the optics. If a resolution of the image of the video signal is less than the resolution corresponding to the optics, the zoom control zooms a projected image.

    摘要： A foldable ramp of the type having two ramp sections each consisting of opposed side rails connected by spaced rungs includes a hinge having a one-piece construction consisting of spaced plates, connected together by one or more ribs, wherein the plates are joined to one another at opposite sides. A sleeve is formed at the juncture of the plates at each side, and a pivot pin extending through each sleeve connects one side of the hinge to a first ramp section and the other side of the hinge to a second ramp section of the foldable ramp.

    摘要： A baggage checking system is described, primarily for use at airports and distinct from airline seat reservation systems. The baggage checking system takes flight numbers, travellers' identification data and baggage tag numbers from check-in and transfer desks and collates it with baggage tag numbers read at baggage loading points. If an attempt is made to load a bag on an incorrect flight an alarm is given at the loading point and the system is inhibited at that loading point until supervisory action is taken. In addition an alarm is given if an attempt is made to load a bag with the same tag number as another bag. Rules concerning when an alarm should be given in relation to tag numbers checked-in, and tag numbers of passengers boarded can be changed at will, even during loading.

    摘要： A wall coupling restrains adjacent walls 2 and 3 from displacement over each other. The two walls have coincident apertures 12 and 16. A flexible moulded plastics retaining strip 5 is carried by the wall 2 on its side remote from the wall 3. The strip 5 overlies the aperture 12 and has an end 8 which is secured relative to the wall 2 and an end 7 which is slidable along tracks on the wall 2 in a direction towards and from the end 8. A mid-length region 6 of the strip 5 between its ends 7 and 8 has integral hinges 13 to 15 so that during displacement of the strip end 7 towards the end 8, the region 6 doubles to project through the apertures 12 and 16 and thereby couple the walls 2 and 3 to restrain them from relative displacement. A combination stop/catch can be provided to temporarily retain the strip end 7 in a position where the mid-length region 6 of the strip is in either a folded or an unfolded condition.
