A method of analyzing the condition of a motor driven rotating system using a current waveform produced by the motor. The method includes receiving channel status information-reference signals for channel status information feedback from a plurality of transmission points, performing radio resource management measurement based on the CSI-RSs, and selecting one or more TPs for receiving a signal from among the plurality of TPs based on the result of measurement. The channels are located approximately at a longitudinal midpoint of the magazine body. The locking mechanism is configured to, whenever the anvil assembly is in the open position, automatically lock the staple driver in the pre-fired position preventing the staple driver from being moved to the fired position. One of the two ends of each of the booms is connected pivotally to a corresponding one of the corresponding one of the rotating members and the seat. Fees are collected by an insurance company for the preservation of umbilical cord blood cells including stem cells, peripheral blood cells or other biological material of the policy holder, a secondary insured, or a beneficiary.
