A scanning type laser induced spectrum surface range analysis and detection system includes a laser emitting head connected to an external laser inducing light source, which generates lasers emitted through the laser emitting head, so as to generate laser induced plasma. A focusing optical device converges induction excited laser beams emitted by the laser emitting head onto a surface of a tested sample. Then, a reflector collects wide spectral range induced plasma scattered light signals of the tested sample and converges the signals into a light collecting device. The light collecting device converges induced plasma scattered light into an optical fiber and transmits the induced plasma scattered light to an external spectrograph; and the external spectrograph divides a spectrum formed by the plasma to obtain spectral strength data of different wavelengths.

The present invention relates to the technical field of data or file synchronization. In particular, the present invention relates to a method and system for data synchronization using character string matching. Provided are a method, computer program product, and system for data synchronization between a source node and target node. An old copy and a new copy of data to be synchronized is received. A block map is generated according to the difference determined using character string matching between the old copy and the new copy. The block map, which includes the position information of unchanged blocks and the position information and contents of changed blocks, is transmitted to a target node.

Data synchronization using string matching

Taught herein is an apparatus for measurement of floating body posture of a person wearing a life jacket, comprising a backpack frame having a plurality of reference points, an image collecting system, and an image processing system; wherein the image collecting system collects image sequence information of the person wearing the life jacket via the reference points; the image processing system processes the image sequence information, so as to obtain the dynamics of a movement of the person and the quasi-static parameters of such movement. The system is capable of reflecting the dynamics of a movement of a body in water and the quasi-static parameters thereof.
