Abstract: A fastener testing device includes a base, a testing unit, a mobile platform, and a prompting unit, tests an installation state between a plurality of installation holes on a subject and fasteners corresponding in position to the installation holes, respectively. The subject is mounted on the base. The testing unit is driven by the mobile platform to move close to the subject and test the installation state. The testing unit generates a test signal in response to a state of contact between the fasteners and probes corresponding in position to the installation holes, respectively. The prompting unit receives the test signal and informs each of the installation holes of a correct installation state or an incorrect installation state. Accordingly, incorrectly-installed ones of the installation holes are directly identified by the fastener testing device quickly, conveniently, and accurately.

Abstract: An overvoltage protection circuit and a portable electronic device having the same are introduced. The overvoltage protection circuit provides overvoltage protection when an input voltage exceeds a rated voltage tolerable by an internal circuit unit in the portable electronic device. A reference voltage and a partial voltage are generated from the input voltage through a voltage limiting unit and voltage dividing module, respectively, and conveyed to a comparing module for comparison. Comparison of the reference voltage and the partial voltage is followed by generation of a switch signal whereby a switch unit determines whether to apply the input voltage to the internal circuit unit. The voltage dividing module sets the maximum rated voltage tolerable by the internal circuit unit and enables the overvoltage protection circuit to give overvoltage protection to the portable electronic device regardless of temperature.
