    • A drop in the access performance to a source volume is prevented by executing various control methods according to the snapshot usage method. A storage apparatus comprises one or more storage devices which provide storage areas; and a controller which creates a logical volume in the storage area provided by the one or more storage devices, and which reads and writes data from/to the logical volume according to a request from a host, wherein the controller acquires one or more snapshots which are data images at certain time points of the logical volume, wherein the controller determines whether the logical volume is subject to abrupt load fluctuations on the basis of performance information of the logical volume and the snapshots, and wherein, if the logical volume is subject to abrupt load fluctuations, the controller executes predetermined control processing according to usage cases of the snapshots.

    • While successively varying its orientation at specific intervals, a detecting apparatus transmits pulsed radio waves from an antenna (1), and data corresponding to input levels derived from one sweep are written in a primary memory (4). output values obtained in preceding signal processing operation are written in a secondary memory (9). A signal comparator circuit (7) determines current output values based on the input levels of the primary memory (4) and the preceding output values of the secondary memory (9) by reference to a table (8) and writes the current output values thus obtained in the secondary memory (9). The detecting apparatus causes display brilliance or color between a blip exhibiting large fluctuation in received signal strength and a blip exhibiting small fluctuation in received signal strength. Alternatively, the detecting apparatus causes the pattern of fluctuation in display brilliance or color according to fluctuation in received signal strength at the same point or at nearby points to vary from one transmit/receive cycle to another depending on whether the received signal strength has once exceeded a specified value or not.
    • 在以特定间隔连续地改变其取向的情况下,检测装置从天线(1)发送脉冲无线电波,并将与从一次扫描得到的输入电平对应的数据写入主存储器(4)。 在先前信号处理操作中获得的输出值被写入辅助存储器(9)。 信号比较器电路(7)通过参考表(8)基于主存储器(4)的输入电平和辅助存储器(9)的先前输出值来确定当前输出值,并且因此写入当前输出值 在第二存储器(9)中获得。 检测装置使接收信号强度的波动大的显示亮度或接收信号强度的波动小的blip之间的显示亮度或颜色。 或者,检测装置根据接收信号强度是否一旦超过,根据接收信号强度的波动在同一点或附近点使显示亮度或颜色的波动图案从一个发送/接收周期变化到另一个发送/接收周期 一个指定的值。
