The present disclosure provides a method of testing a single device under test (DUT) through multiple cores in parallel, which includes steps as follows. The test quantity of the DUT is calculated; the test quantity of the DUT is evenly allocated to to a plurality of test cores, so as to control a period of testing the DUT through the test cores in parallel.

System and method of testing single DUT through multiple cores in parallel

A test system includes a plurality of test core devices and a plurality of first buses. The plurality of test core devices are electrically connected to a device under test (DUT). The plurality of first buses are electrically connected to the test core devices, where at least one set of test core devices selected from the plurality of test core devices are merged to be a merged test core device through one or more of the plurality of first buses.

Test system and method of operating the same

A test device is provided. The test device includes test components, power supplies, an alternating current (AC) power detection circuit and an alert module. The power supplies convert an AC power through a first wire, a second wire and an earth wire to a direct current (DC) power and supply the DC power to the test components. The AC power detection circuit receives the AC power through the first wire, the second wire and the earth wire to determine whether both of voltage differences between the first wire and the earth wire and between the second wire and the earth wire is outside of respective predetermined ranges. When both of the voltage differences are outside of the corresponding predetermined range, the AC power detection circuit controls the alert module to generate an alerting signal.

Test device and alternating current power detection method of the same

A steering wheel-shaped joystick of an arcade game machine is provided. The steering wheel-shaped joystick is rotated to generate a direction signal and send it to the arcade game machine. The steering wheel-shaped joystick includes a plurality of rods which are radiantly distributed, and includes at least one button at the end of the rods. The button is used to generate a function signal and send it to the arcade game machine so as to control ship-related electronic games of the arcade game machine.

Steering wheel-shaped joystick for arcade game machine

A cellular phone battery charger includes a housing, a control circuit assembly mounted within the housing, the control circuit assembly having a power jack for obtaining power supply from a car battery by a cable or a city power supply outlet by a transformer, a coupling element mounted in the housing at the rear side to hold any of a variety of cellular phone connectors for connection to a particular cellular phone, and a batter holder mounted in the housing at the front side and electrically connected to the control circuit assembly for receiving a 9V alkaline battery for providing battery power supply to the connected cellular phone in an emergency case.
