摘要： A code modulation and demodulation method includes removing a DC component of a code stream to be modulated when source data is recorded on an optical information storage medium and controlling a suppression of the DC component contained in the code stream when the source data is converted into a codeword to be recorded on an optical information storage medium. The method includes determining a control timing to suppress the DC component of the code stream to which the source data are converted, performing a code conversion at each control time for the DC component so that the code stream branches into a pair of branch code streams one of which extends in a direction where a running digital sum (RDS) of the code stream increases, and another one of which extends in the direction where the RDS of the code stream decreases, and selecting the path of the code stream that has a most bounded path around RDS ‘0’ from the paths of the branch code streams each control time. By performing a regular DC suppression control when the source data is converted, and by selecting one of the branch code streams when the DC suppression control is performed, more DC components in the code stream can be effectively removed.

摘要： A swing angle measuring apparatus generates feedback signals for closed loop regulation of a load swinging motion in operation of a crane. The swing angle measuring apparatus measures two-dimensional swing angles, and includes a rope fixed to a hoisting device, two laser displacement sensors, laser reflecting plates, and a rectangular box attached to a hoisting device. Two steel reflecting plates are installed on the periphery of the fixed rope. Two laser displacement sensors are installed in a rectangular box such that the heading of the sensors are configured to perpendicularly intersect the faces of the laser reflecting plates. The configuration of the displacement sensors and the reflecting plates can be reversed. The rectangular box is attached to the hoisting device, and the laser reflecting plates are placed at an offset distance away from the face of the laser displacement sensors, at which a sensor signal of 0 volts is obtained. The swing angle of the rope or cable is determined from the distance between the laser displacement sensors and the laser reflecting plates.
