Abstract: The present invention provides a method for decoding a low density generator matrix code (LDGC), applied for decoding transmitted original information bits encoded in LDGC code.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A golf launching monitoring arrangement allows equipment to be placed at a position behind the player (i.e., behind the golf ball), to measure both club and ball movement. A 3D scan of the club head before the play serves two purposes: 1) 3D registration that enables accurate measurement of the club head position and orientation for the camera system measuring the club movement from the back; 2) for reconstruction of the launching scene. With a 3D model of the club head, a simple 3D model of the golf ball and accurate measurement of their movement during the play, a full 3D golf launching scene can be reconstructed authentically. With this reconstruction, the movement of both the club head and the resulting ball movement can be replayed at any viewing angle, with any frame rate and at whatever resolution for the players or the coaches to view and analyze.
