Abstract:
A testing method tests a handheld electronic device installed with an open operating platform and having a touchscreen. The testing method includes the steps of executing a screen test program installed on the open operating platform to start a testing procedure; generating test coordinates by the screen test program; performing a touch selection operation based on the test coordinates by the touchscreen; and performing a functional operation by the open operating platform in response to the touch selection operation. The testing loop is repeatedly executed to simulate the ways a user may exercise touch control over the handheld electronic device to cause the handheld electronic device to hang or cause damage to software programs thereof. Accordingly, the testing method enhances the reliability of testing the handheld electronic device.
Abstract:
A printed circuit board testing device for performing electrical tests on a printed circuit board having test contacts includes a test platform. An installable and uninstallable positioning module is disposed on the test platform and adapted to receive the printed circuit board. The positioning module has through-holes corresponding in position to the test contacts. A dial module is disposed between the test platform and the positioning module, and has a needle corresponding in position to the through-holes, such that the distance between the dial module and the positioning module can be altered to cause the needle to penetrate a corresponding one the through-holes, insert into the positioning module, and come into contact with the test contacts to facilitate the electrical test. The printed circuit board testing device can perform electrical tests on any printed circuit boards having the test contacts, by changing the positioning module and the dial module.
Abstract:
A test device with uninterruptible power supply supplies external power to a product under test (PUT) and performing electric power tests thereon. The PUT has a processing unit, a power input end, a battery connection end, and a charging and discharging circuit. The device includes a first test port, a second test port, and a power-storing unit. The PUT is electrically connected to the first and second test ports to receive the external power through the first test port and be switchable to the second test port to selectively receive power from the power-storing unit, thereby preventing interruption of operation of the PUT. A charging voltage from the charging and discharging circuit is applied to the power-storing unit via the second test port to charge the power-storing unit. An operation-required power level of the PUT can be maintained, even if the test device receives no power.

Abstract:
A charging method and a charging system are introduced for controlling a charging current by a PWM method. A charging IC is controlled to supply the charging current to a battery, and a control unit is used to generate a PWM signal with a duty cycle, and a filter unit is used to convert the PWM signal into a voltage signal to be supplied to the charging IC, and the control unit determines whether a current of a battery detected by the battery status detection unit reaches a regular current, so that a PWM signal with a duty cycle greater than the previous duty cycle by a default increased cycle is provided if the detected current has not reached the regular current. Thus, the feature of the PWM signal is used to set the charging current according to the capacity of the battery automatically.
