20110279267 | DISPLAY DEVICE WITH ALARM FUNCTION - A display device includes a dial, an alarm setting member, and a warning unit. The alarm setting member includes an A/D converter, a recognition module, a storage module, and an analysis module. With rotation of the dial, a variation voltage is generated. The A/D converter converts variable voltage from analog to digital form. In contrast, the alarm time is decreased. The storage module stores the adjusted alarm time. The analysis module compares the current time with the preset alarm time and outputs a driving signal to the warning unit in the event of a match. | 11-17-2011 |
20120047401 | TEST DEVICE AND TEST METHOD FOR TESTING COMPUTING DEVICE - A test method for restarting a computing device communicating with a remote computer. The computing device is shut down and awakened by the remote computer. A second hardware information of the computing device after restarting the operating system of the computing device is compared with initial hardware information of the computing device when the computing device is initial started. Test results are stored to a predetermined storage path and displayed on a screen after the test ends. | 02-23-2012 |

20120249299 | CONTROL CIRCUIT FOR INDICATOR LIGHT - A control circuit for an indicator light includes a power source, a switch unit, a ground resistor, and a first adjusting unit. The power source supplies a voltage. The switch unit is connected between the power source and the indicator light and turns on or turns off the indicator light. The ground resistor is connected between the power source and the ground via the indicator light and the switch unit. The first adjusting unit includes a first adjusting resistor and a first control switch. The adjusting resistor is connected between the indicator light and the ground via the first control switch. The first control switch is capable of connecting the first adjusting resistor with the ground resistor in parallel. | 10-04-2012 |
20130100609 | CONTAINER DATA CENTER - A container data center includes a temperature control system to monitor a temperature of the container data center. The temperature control system includes a temperature sensor to sense the temperature of the container data center. The temperature control alarm system determines whether the sensed temperature is greater than first and second predetermined temperatures. The second predetermined temperature is greater than the first predetermined temperature. If the sensed temperature is greater than the first predetermined temperature, a cooling device is turned on to cool the container data center. If the sensed temperature is also greater than the second predetermined temperature, an alarm device is started and an alarm message is transmitted to a monitor center. | 04-25-2013 |
