Abstract: A method and system for managing and organizing objects in a virtual workspace is disclosed. The method and system display a plurality of objects and containers on the virtual workspace. The objects and containers are assigned to corresponding layers. The method and system receive user input for changing the corresponding layer of one or more of the objects and containers, recursively fit test each of the layers for an overlap between the one or more of the objects and containers and each container assigned to each layer based on the user input, incorporate the one or more objects and containers into a target container assigned to a target layer when the overlap exceeds a predetermined threshold, and assigns the one or more of the objects and containers to a background layer when the overlap fails to exceed the predetermined threshold in the fit testing.

Abstract: A method is proposed for calculating a line performance, or stability, measure for a telephone line. Various physical parameters associated with the line, such as insulation resistance, capacitance and DC voltages, are measured. The values for each of the parameters are compared to expected values, which are based on historical values measured for that line. Individual performance measures for each parameter are calculated based on the difference between the actual and expected values, normalised by the deviation of that parameter. The deviation accounts for general fluctuations across all the lines. A weighting value is also applied, based on knowledge of values relevant to the good operation of lines. The deviation effectively gives a scaling, and the weighting gives a context to the measured values for a single line. The individual performance measures are summed to get the final performance measure for the line.

Abstract: An image projecting method comprises determining the position of a projection surface within a projection zone of at least one projector based on at least one image of the projection surface, the projection zone being sized to encompass multiple surface positions and modifying video image data output to the at least one projector so that the projected image corresponds generally to the projection surface.

Abstract: An apparatus for detecting a pointer within a region of interest includes a first reflective element extending along a first side of the region of interest and reflecting light towards the region of interest. A second reflective element extends along a second side of the region of interest and reflects light towards the region of interest. The second side is joined to the first side to define a first corner. A non-reflective region generally in the plane of at least one of the first and second reflective elements is adjacent the first corner. At least one imaging device captures images of the region of interest including reflections from the first and second reflective elements.
