    摘要： A flexible sensor is provided. A further aspect employs a sensor apparatus including pressure or force sensing layers or sheets in addition to location sensing layers or sheets. In another aspect, an electrical sensing circuit and flexible films are used to sense pressure and/or location of a contacting object. In another aspect, a compressible polymer includes conductive particles therein such that the compressible polymer changes electrical resistance when compressed to indicate a force or location. Still another aspect has stacked sandwiches of pressure and/or location sensing films, layers or sheets.

    摘要： A process for the continuous production of thin-walled, radially closed hollow profiles which are composed of nonferrous metals and have a small cross section comprises supply of a flat strip of the nonferrous metal to a forming apparatus (212) at a first supply speed, where the thickness of the strip corresponds to the wall thickness of the hollow profile. The forming apparatus (212) is configured for continuous forming of the flat strip supplied into a shape corresponding to the hollow profile. After forming, two opposite edges of the flat strip rest flush against one another in a contact region. A welding apparatus (216) continuously welds the edges which rest flush against one another by means of a laser which emits light having a wavelength of less than 600 nm. The laser heats a point in a welding region which has a diameter which is less than 20% of the cross-sectional dimension of the hollow profile. The welded hollow profile is taken off from the welding region, provided in a corrugator (225) is with parallel or helical corrugation in sections and taken up in an uptake device (226).

    摘要： The invention relates to a method for controlling the stress distribution in a material, comprising the steps of: a, preparing a crosslinked polymer containing reversible exchange bonds; b, applying an external force to the crosslinked polymer to cause a certain strain; c, specific region of the crosslinked polymer is selectively heated while maintaining the strain. This method controls and utilizes the internal stresses which are commonly considered as unfavorable. The invention also provides a method for reading information in a polarized light field, wherein the crosslinked polymer treated by the method is transparent under natural light. The information therein can be read only under polarized light, and possesses concealment.

    摘要： A climb assist system dynamically adjusts a rate and a level of load assist that the system provides to a climber during traverse of a structure. The system includes a load sensor system configured to detect the state of the climber, such as the load applied by the climber to an assist rope, to provide an upward support force on the climber to compensate the climber's weight. Additionally, the system includes a sender configured to transmit data to a receiver of the system. The system includes a controller configured to interpret the received data and thereafter provide control through a controlled motor and drive system to provide load assist to the climber. A safety function of the system is configured to receive data indicative of a rate of descent of the climber, and slow or stop the descent if one or more conditions are met.
