Abstract: A method for residual stress enhancement for a coil spring includes radially expanding at least a select axial portion of the coil spring to remove residual tensile stress from the spring inner diameter and induce residual compressive stress in the spring inner diameter. The spring is expanded by radial force on the inner diameter and/or by a helical unwinding force induced by rotating at least one end of the spring relative to the other end of the spring. A tool includes a spring expansion portion and, optionally, a diameter control portion. Cylindrical, conical and/or beehive springs are processed to enhance residual stress.

Abstract: A method and system to sense an amount of material such as toner in a container held in a horizontal position within a machine, such as a printing machine. A level sensor senses an amount of material within a dispensing unit which causes the level sensor to issue a signal. The dispensing unit is external to the container. The container holding the material is rotated, and a rotation direction reversed to a direction normally used to dispense the material. The reverse rotation direction moves the material to a closed end of the container. The container is then moved in a forward direction following the rotation of the container in the reverse direction. The forward rotation moves the material to the open end of the container, and the material further moves into the dispensing unit. A signal is generated when a sufficient amount of material has been moved into the dispensing unit.

Abstract: A de-warp map is generated by applying principal component analysis (PCA) to vectors describing aspects of identified features of an object in an image. PCA provides vectors and coefficients describing curvature or image warping at selected points in the image. Estimates of the warping of the image generally are generated by interpolation and/or extrapolation from the vectors and coefficients provided by PCA. In some applications only two features need be identified. For example, the complicated curvature of the facing pages of an open book can be characterized by two vectors describing positions of top and bottom edges of the book. In such applications PCA can reduce to vector subtraction to determine a basis vector, vector addition and scaling to determine an average vector and simple assignment of known coefficient values. The de-warping map can be used to generate a de-warped version of the image.

Abstract: The invention concerns a method of transmitting video data comprising information bits (201), a video processing unit (10, 20, 40) with a control unit (12, 22, 42) for sending and/or receiving such video data, and a computer program product for the execution of said method. The method comprises the application of a systematic channel encoding (202) on the information bits (201) of the video data and obtaining a sequence comprising the encoded information bits (203) and error correction bits (204, 403) of the information bits (201). For transmission to another video processing unit (10, 20, 40), the encoded information bits (203) and the error correction bits (204, 403) are inserted into a primary coded picture network abstraction layer (205, 401) and a redundant coded picture network abstraction layer (206, 402), respectively.
Abstract: A method of imposing a shape on an intact blood vessel other than a graft includes inserting a stent in the vessel. The stent includes a supporting portion which internally supports an interior wall of the vessel. The supporting portion includes a hollow tube, the walls of which have openings therein so that the interior wall of the vessel is exposed via the openings to fluid flow along the vessel. A central axis of the hollow tube forms a non-planar three dimensional at least partially helical shape. The hollow tube imposes the three-dimensional at least partially helical shape on the central axis of the vessel, inducing a swirling fluid flow within the stent supported part of the vessel.

Abstract: Different arrangements for improving the coupling-in efficiency between an LED assembly and a light guide are disclosed. In a first arrangement, a substantially planar end of a light guide is seated on a perimeter wall of a support that encloses a LED assembly, and a reflecting surface enhances coupling efficiency of a light guide. Alternative arrangements use a separate coupler disposed between the LED assembly and the light guide, which coupler has a paraboloid or aspheroid conformation to develop substantially collimated light that is directed into the light guide. The cavity around the LED assembly and within the coupler, may be air or a material having an index of refraction that closely matches the index of refraction of the light guide material.
