An intermediary apparatus, an intermediary method, and a computer program product thereof for storing data in a storage apparatus, and a data storage system comprising the same are provided. When the thermal condition is reached, command signals are generated that cause a needle of the surgical instrument to either have its vibrational speed slowed, have its vibrational movement stopped, or have it withdrawn from its relative position. The pair of first linear portions is in straight liner shapes and distant from both the tip end and the base end. The consistent carcass size enables manufacture of consistent carcasses which, in turn, facilitates providing substantially the same size meat cuts. Since an output of a phase locked loop is generated according to a variable phase locked loop data, pseudo carrier signals having different frequencies can be obtained by one pseudo carrier generator. The laser scanning device further includes an abnormal condition detector that detects the laser power control signal received by the reference voltage generator.
