Abstract: A temperature controller is provided, which includes a first temperature sensor, a heater, a logic circuit, a watchdog circuit and a second temperature sensor. The first temperature sensor may detect the environmental temperature. The heater may be turned on after the temperature controller is turned on. The logic circuit may turn on the watchdog circuit after the environmental temperature is higher than the first temperature for the watchdog circuit to keep detecting whether the main circuit of an electronic device is turned on until the main circuit is turned on. The second temperature sensor may be turned on after the main circuit is turned on and then detect the environmental temperature. The logic circuit may turn off the heater after the second temperature sensor detects the environmental temperature is higher than a second temperature, or turn on the heater when the environmental temperature is lower than a third temperature.

Abstract: Disclosure herein is related to a system for testing wireless signals and a method provided for establishing the system. One of the objectives is to establish one new testing system while the method effectively reduces the unstable problem caused by hardware or environmental variations. The testing system measures intensity of the wireless signals outputted from a device-under-test. While compared to a test signals, it is determined if the signal intensities there-between are balanced. Accordingly, the hardware of system is required to be adjusted. After that, the wireless signals are compared with sample signals for determining whether or not the test results are stable among the different testing system. An attenuation value may be introduced to adjusting the test result. A new testing system is therefore established.
