Abstract: A method of manufacturing burr-edged reflecting tile elements for a mosaic X-ray lens configured for forming an X-ray beam comprises steps of: (a) providing a single crystal having first and second faces thereof being parallel therebetween; single crystal having crystallographic planes thereof being parallel to first and second faces of the single crystal; the first face dedicated for reflecting an X-ray beam to be incident thereto; (b) cutting the single crystal by means of a wire electrical discharging machine normally to the main faces. The step of cutting the single crystal comprises moving a wire within a cut in direction from the second face to the first face; such that burrs configured for reflecting the X-ray beam to be incident thereto are formed on edges of the cut.

Abstract: A gesture recognition method comprises receiving at a processor from a sensor a sequence of captured signal frames for extracting hand pose information for a hand and using at least one trained predictor executed on the processor to extract hand pose information from the received signal frames. For at least one defined gesture, defined as a time sequence comprising hand poses, with each of the hand poses defined as a conjunction or disjunction of qualitative propositions relating to interest points on the hand, truth values are computed for the qualitative propositions using the hand pose information extracted from the received signal frames, and execution of the gesture is tracked, by using the truth values to determine which of the hand poses in the time sequence have already been executed and which of the hand poses in the time sequence is expected next.
