Abstract: A product testing system and an auxiliary testing method are provided. The product testing system includes a computer and a test fixture. The computer has a machine learning model. The auxiliary testing method includes the following steps. Firstly, the test fixture tests the plural under-test products sequentially, and generates corresponding test data to the computer. Then, the computer generates plural trend line graphs corresponding to the test data. Then, the operator determines corresponding human judging results according to the trend line graphs. The test data, the trend line graphs and the human judging results are inputted into the machine learning model, and a learning process is performed. If the number of samples reaches a predetermined threshold value, the machine learning model generates auxiliary judging results according to the corresponding test data and the corresponding trend line graphs.

Abstract: A testing system uses different operating systems to test electronic products. The testing system includes a master computer, a slave computer and a relay. A first operating system is installed in the master computer. A second operating system is installed in the slave computer. The master computer and the slave computer are connected with each other through RS-232 ports. The relay is connected with the master computer, the slave computer and an under-test product. By changing the voltage level state of specified pins of the RS-232 ports, the master computer notifies the slave computer to test the under-test product. Moreover, by controlling the relay, the connection between the master computer and the under-test product is switched to the connection between the slave computer and the under-test product. Consequently, the under-test product is tested by the slave computer.

Abstract: A controlling method of a computer screen includes the following steps. Firstly, in a step (a), an image is captured. Then, a step (b) detects whether the image has a skin color distribution region. If an accumulative time length that no skin color distribution region is contained in the image is longer than a predetermined time length, a hibernation mode of the computer screen is enabled.

Abstract: The present invention relates to a testing system, including a testing host and a relay host, where the testing host may test a tested target, and a testing program is installed in the testing host. In a process of testing the tested target, the testing program may generate testing history information of the tested target, and the testing host changes a file name of the testing history information according to a renaming rule. The relay host includes a default function and a transferring and processing program, where the transferring and processing program may capture testing content information applicable to the default function from the file name of the testing history information, and apply the testing content information to the default function to generate function data. Therefore, an operation of generating the function data may be simplified.

Abstract: A wireless sound output device includes a wireless earbud and a charging base. The wireless earbud is placed in the charging base. If a true wireless stereo Bluetooth controller of the wireless earbud detects that a mode switching circuit of the charging base is switched to a wireless Bluetooth receiver mode, an analog signal is transmitted to an audio source output hole of the charging base through an audio source analog signal output switching unit of the wireless earbud.

Abstract: An information management method for a testing network framework is provided. The testing network framework includes a first server and at least one computer. The method includes the following steps. Firstly, the at least one computer downloads and executes a test application program. Then, the at least one computer is connected to the first server, and provides a device identification code and a network address value of the at least one computer to the first server. If the first server judges that the corresponding device identification code complies with a first default condition and the corresponding network address value complies with a second default condition, the corresponding computer is authenticated, and a test setting information is provided from the first server to the corresponding computer. After the test setting information is downloaded to the corresponding computer, a test process is performed.

Abstract: A testing device includes a base body, a holder, an electrically conductive plate, plural testing probes and plural insulation structures. The testing device of the present invention uses the electrically conductive plate to replace the plastic plate of the conventional testing device. Consequently, the electrostatic discharge effect is avoided. Moreover, the insulation structure is arranged between the testing probe and the electrically conductive plate to separate the testing probe from the electrically conductive plate so as to avoid the electric leakage problem. Consequently, the testing device of the present invention is capable of avoiding the electrostatic discharge effect without causing damage of the under-test object and reducing the measurement accuracy.

Abstract: An input module includes an input device and a control program. The input device is in communication with a computer. The control program is installed in the computer. If a control signal from a processing unit of the input device has not been received by the computer for a predetermined time period after the control program is opened, the control program issues a command signal to the processing unit. After the command signal is received by the processing unit, the processing unit issues at least one response signal to the computer so as to prevent the computer from entering a hibernation mode.

Abstract: An electronic scale calibrating method for an electronic scale is provided. The electronic scale includes a weighing pan, a memory unit, a first weight sensor and a second weight sensor. The weighing pan has a placement region. The first weight sensor and the second weight sensor are symmetric with respect to the placement region. Firstly, two standard samples are placed in the placement region simultaneously. Then, the first weight sensor and the second weight sensor sense the two standard samples to obtain a first read value and a second read value, respectively. Then, a first parameter, a second parameter, a first calibration coefficient and a second calibration coefficient are defined according to the first read value and the second read value. Then, a calibration formula is generated and stored in the memory unit.
