Abstract: An LED backlight (15) having a plurality of LED groups (19) each including a plurality of LEDs (17) connected in series is tested. The LED groups (19a to 19c) are driven with a constant current respectively, and operating voltages (Vf1 to Vf3) of the LED groups (19a to 19c) are measured respectively. The LED backlight (15) is determined as normal when all of differences between the operating voltages (Vf1 to Vf3) are less than a reference value, and is determined as abnormal otherwise. With this, an open circuit failure and a short circuit failure of the LED (17) can be detected. A leakage failure of the LED (17) may be detected by switching an amount of a drive current used for driving with the constant current, to a minute current. Thus, the LED backlight is tested certainly and easily.

Abstract: A test system is characterized by including: a holding unit that holds a light-receiving unit receiving light emitted from a test object; and an optical path forming unit that is formed with an optical transmission path as a path of the light received by the light-receiving unit, in which the optical transmission path is formed of a different member from the light-receiving unit. Since the test system has such a configuration, replacement of the light-receiving unit that receives the light emitted from the test object can be facilitated.

Abstract: Aspects of the subject disclosure may include, for example, a transmission system having a coupling device, a bypass circuit, a memory and a processor. The coupling device can facilitate transmission or reception of electromagnetic waves that propagate along a surface of a transmission medium. The memory can store instructions, which when executed by the processor, causes the processor to perform operations including restarting a timer to prevent the bypass circuit from disabling the transmission or reception of electromagnetic waves by the coupling device. Other embodiments are disclosed.

The quick-action leakage detection protection circuit may include a power input end, a power load end, a power user end, twin induction coils for detecting leakage current and low resistance failure, a control chip, a trip coil in which an iron core is disposed, a reset button, a self-checking chip, and a self-checking silicon controlled rectifier. The reset button may be linked with a main circuit switch, an analog path switch, and a normally-open self-checking path switch. The main circuit switch may include a pair of dynamic contact levers extended from the power load end, a first pair of static contact ends extended from the power input end passing through the twin induction coils, and a second pair of static contact ends extended from the power user end. In some embodiments, a first end of the trip coil may be connected to a live line end of the power input end and to the live line of the power load end via the first normally-closed switch. And, a second end of the trip coil may be connected to a neutral line end of the power load end via a second normally-closed switch.
