    摘要: A tensioning device for a traction mechanism drive for a belt drive that is incorporated in an internal combustion engine, in order to drive components of the engine or installed accessories. The tensioning device has a construction that is advantageous under production and construction viewpoints, by a high degree of robustness, and also by an advantageous mechanical operating behavior. The tensioning device includes a base part, a swivel arm, a torsion spring with a first winding end section that is allocated to the swivel arm and a second winding section that is allocated to the base part for applying a pivoting moment acting between the base part and the swivel arm and forcing the swivel arm in a tensioning direction, and a damping device for generating a damping force that counteracts a pivoting of the swivel arm directed against the tensioning direction. This damping device includes a first friction surface element that is arranged in a region of the winding end section of the torsion spring allocated to the swivel arm, and forms a friction surface that is used for applying friction force and that sits on a counter friction surface. In the region of the second winding end of the torsion spring for the base part, there is a second friction surface element that forms a friction surface that sits on a counter friction surface, and the counter friction surface is formed by a friction surface structure that can pivot together with the swivel arm.

    摘要: A method for intrusion detection in an optical fiber communication network. The method includes at a first location on an optical fiber segment, receiving a set of multiple optical signals having wavelengths differing from each other, measuring received signal power for each of the received multiple optical signals, and repeating the receiving and the measuring steps. Each optical signal in the repeated steps has same wavelength as corresponding received optical signal in the initial steps. The method further includes computing a signal power loss between each received optical signal in the repeated set and the corresponding optical signal in the initial set, fitting a curve of signal power loss vs. wavelength to the computed signal power losses using a statistical analysis, and if the signal power loss of the curve over a preselected wavelength band is at least as great as a preselected minimum loss level, providing intrusion notification.

    摘要: A retractable shade finding particular use in covering non-linearly aligned architectural openings or curved openings, includes one continuous curtain following a predetermined path along the openings. A segmented drive system forms linear segments of a drive system which in combination are adjustable to accommodate various curvatures of openings or angles between adjacent architectural openings. Movement of the shade between retracted and extended positions is automatically stopped and a fail-safe system is provided to prevent inadvertent extension of the shade such as when the shade is used to cover the windshield of a recreational vehicle or the like.
