Abstract: A method for detecting a moving object in a scene includes providing sampled ultrasonic echo signals from the scene; determining echo envelopes of the sampled ultrasonic echo signals; determining differentials of successive echo envelopes for providing echo envelope differentials; determining the absolute values of the echo envelope differentials; and conducting a classification based on the determined absolute values of the echo envelope differentials for determining a relative movement of the moving object.

Abstract: A method for modulating T cell activity by modulating the intracellular concentration and/or activity of NAADP+, compounds capable of modulating the effect of NAADP+ on T cell Ca2+ levels, and methods for identifying the same, are described.

Abstract: A flexible work station (1) and an operating method for processing, especially the joining and geometric welding of two or more different types of components (4, 5). The work station (1) has a component feed device (6, 7), one or more flexible processing places (2) with a plurality of movable and type-related positioning devices (14, 15) with a clamping device (16), as well as one or more processing devices (13) and at least one transport device (9). The transport device (9), which is preferably designed as a robot, has a plurality of replaceable and type-related gripping tools (10, 11), with which it transports the components (4, 5) from the component feed device (6, 7) to the positioning devices (14, 15). In the case of a change from one component to another, the gripping tool (10, 11) is changed as well, and the old gripping tool (10, 11) is laid down on a gripper rest (22) at or on the components (4, 5), which are just located on the positioning device (14, 15) or on the component feed means (6, 7).

Abstract: Workpieces of unequal configuration are to be treated within an assembly line. For this purpose, suitable clamping frames are provided to hold the workpieces. These are moved about a common axis which extends laterally above an assembly line direction. While the upper edge of each individual clamping frame is hinged to an element which is rotatable about the axis, the lower edge is guided in a fixed guideway toward a working position. A common guideway length of two fixed guideways is movable into the working position transversely to the assembly line direction.
