The invention relates to a method for determining a periodic pattern in an amplitude spectrum, for example, in a Doppler spectrum of a radar echo. A residual spectrum is formed using Fuzzy Set Theory, and the periodic pattern is determined for each residual spectrum by histogramming the original spectrum. The method can be used for identifying aircraft, for example helicopters, that have periodically-moving components, e.g., rotors, that generate a periodic pattern in a Doppler spectrum.

In an animation processing system, generating images to be viewable on a display using a computer that are generated based on scene geometry obtained from computer readable storage and animation data representing changes over time of scene geometry elements, but also images can be modified to include shading that is a function of positions of objects at other than the current instantaneous time for a frame render such that the motion effect shading would suggest motion of at least one of the elements to a viewer of the generated images. Motion effects provide, based on depiction parameters and/or artist inputs, shading that varies for at least some received animation data, received motion depiction parameters, for at least one pixel, a pixel color is rendered based on motion effect program output and at least some received scene geometry, such that the output contributes to features that would suggest the motion.

The invention relates to a device (1) for coating workpieces (2), preferably consisting of wood, wood-based materials, plastics material or the like at least in sections, comprising a feed device (10) for feeding a coating material (12), a pressing unit (20) for pressing the coating material (12) against a surface (2a) of a workpiece (2), a conveyor device (4) for bringing about a relative motion between the pressing device (20) and the respective workpiece (2), an energy source (30) for applying energy onto the coating material (12) and/or the workpiece (2), and a control device (50) for controlling at least the energy source (30). The device according to the invention is characterized in that the energy source (30) comprises at least two energy generating sections (30′, 30″), wherein the control device (50) is equipped to operate at least two energy generating sections (30′, 30″) at least intermittently with at least one operating parameter, the parameters being different from each other, or the energy generating sections are different from each other.
摘要:
A switch includes a contact mechanism having at least one contact and defining a longitudinal axis. Actuation of a handle moves the contact mechanism transversely to the longitudinal axis between an open position and a closed position in relation to at least one fixed contact, whereby a contact spring loads the contact mechanism to seek the closed position. A support part is operatively connected to the handle and forms an abutment for support of the contact spring. The support part is moveable relative to the contact mechanism. Operated by the handle is a locking mechanism which is constructed to hold the contact mechanism in an intermediate position between the open and closed positions to maintain the contact of the contact mechanism at an electrically insulated distance from the fixed contact. A release mechanism interacts with the locking device for releasing the contact mechanism to move to the closed position.

In the case of a system for controlling a hydraulic variable displacement pump, the latter is acted upon in the direction of increasingly pump capacity over an energy storage system and, in the opposite direction, over a hydraulic adjusting device, the adjustment of the variable displacement pump being controlled over a flow regulator, which is constructed especially as a restrictor and the passable cross section of which is variable and which is located in the connection between the adjusting device and the reservoir, and which, for the sudden increase in the pump capacity of the variable displacement pump, opens up a drainage cross section to the reservoir, over which cross section an almost loss-free drainage of the pressure medium, displaced by the admission over the energy storage system, is possible.

A blocking mechanism for a seat belt retractor has a belt reel (10) rotatably mounted in a frame (12), a ratchet toothing (16) arranged on the frame, a ratchet pawl (24) arranged on the belt reel (10) for cooperation with the ratchet toothing (16) and an inertial disc (20) used as a belt webbing-sensitive sensor element. The inertial disc (20) is rotatable relative to the belt reel (10). The ratchet pawl (24) is pivotally mounted on the inertial disc (20). The belt reel (10) has an actuating element (26a) engaging the ratchet pawl (24). In operation, the actuating element (26a) causes the ratchet pawl (24) to engage with the ratchet toothing (16) when the belt reel (10) is rotated relative to the inertial disc (20).

A linear drive for a belt tensioner comprises a pyrotechnic propellant charge, a cylinder tube and a piston displaceably arranged therein. The propellant charge, upon ignition, provides a pressurized gas acting on the piston. The piston has a hollow interior adapted to be subjected to the pressurized gas and an axial end at which an end wall is provided. The end wall has a bursting disc arranged facing the interior of the piston and a through opening formed by a stepped bore. The stepped bore has a first section facing the interior of the piston and is provided with an edge facing the interior, and a second section adjacent the first section. The second section has a diameter which is smaller than a diameter of the first section. The bursting disc abuts at the edge of the first section of the stepped bore.
