A computing system is described that receives, at a particular time, notification data, the notification data indicating a threshold amount of time for which the computing system is to delay outputting an alert based on the notification data. In the device, an oscillating signal having a period varied depending on temperature change is generated below a specific temperature, and a period of a first period signal is compared with that of the oscillating signal applied from a temperature compensated self-refresh circuit unit over the specific temperature. In a second time period following the first time period and including a stable period in which a rotational speed of the transport motor is stable, the processing unit supplies the exciting current of a second current value, the absolute value of which is smaller than that of the first current value, to the branch motor. In a preferred embodiment, each of the light emitting segments includes an indiumtin oxide layer segment covering the LEP optical fiber wherein each of the ITO segments is connected to an ITO control voltage for turning on and off the light emitting segment. Each linking rod is connected at one end to a stud which is to secure with on end of a brake wire. Optional adjustment algorithms are disclosed, including a contrast adjustment, saturation adjustment and intensity adjustment.
