A device and a method for controlling a system component of an information system having at least one sensor and at least one processing unit are provided. In certain aspects, flow control mechanisms implemented in a switch device or other network device manage buffer and system level resources using a scheduler to control the amount of data requested from a local SAN fabric. A stop element in each channel prevents the lower ends of the scaffold legs from being placed against the upright frame. The backlight control section generates the first dimming signal and the second dimming signal and supplies the first dimming signal and the second dimming signal to the fluorescent tube to control luminescence brightness of the backlight unit. Finally, the method includes detecting the presence of an anomaly in the mechanical drive train based on the torque profile or spectrum.
