摘要： The present invention provides a helical slow-wave structure, including a helix, a metal barrel and several supporting rods. The plurality of supporting rods may be inserted into the lines of the grooves tightly, this increases the contact area between the helix and the plurality of supporting rods. With a proper assembly method, the thermal contact resistance between helix and supporting rod may be decreased. So, the invention may enhance the capability of transferring the heat out of the helical slow-wave structure. The helix may have higher heat capacity, therefore, the helical slow-wave structure may become more firm, and more reliable.

摘要： A spring supported lower clamper for direct tensile test, comprising a lower connection member, a lower end cap for holding a sample, a lower chain for connecting the lower connection member with the lower end cap, and spring-type supporting provisions for supporting a broken-apart lower part of the sample formed during the tensile test and the lower end cap. During the tensile test, the sample, the lower end cap and the lower chain are supported by the spring-type supporting provisions. Thus the sample can be prevented from being broken abruptly when a tensile force in the sample reaches its maximum level, and the mechanical behavior after the maximum tensile force is reached can be measured.

摘要： A local positioning system is proposed for wirelessly locating an object using existing features within a static environment, such as walls, as the references for determining the position of the system. An antenna 16 attached to the object transmits RF signals which are reflected by the surroundings. During a training mode, the reflected signals are used to train a neural network 22, 43 to map the position of the object to the characteristics of the reflected signals. During a working mode, the trained neural network is to identify the position of the object based on reflected signals in working mode. Optionally, the reflected signals may be subject to a clustering process before input to the neural network.

摘要： Data is recovered from a write-once optical disk having data written on it. The disk is composed of a substrate and a dye layer. The data was originally written to the dye layer as patterns of pits and lands, but the dye layer is subject to corruption due to ageing so that the data cannot be read by a conventional read process. The data is recovered by exposing the surface of the substrate, measuring deformations to that layer caused by the write process, and extracting the data from the measured deformations by classifying the measured deformations into deformations typical of predetermined patterns of pits and lands.
