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.

Wireless sound output device with charging function

A method for communicating with an under-test object and a communicating system are provided. The method includes the following steps. A command signal is provided from a processing unit of the communicating system to the under-test object, and the processing unit waits for receiving a response signal from the under-test object. If the response signal from the under-test objecthas not been received by the processing unit for a predetermined waiting time period, the command signal is provided to the under-test object again and the predetermined waiting time period is adjusted. There is an exponential relation between the predetermined waiting time period and the number of times the command signal is provided to the under-test object.

Communicating method and communicating system

A camera module testing method is applied to a camera module including a camera lens and a photosensitive element. In a step (A), an original image is captured through the camera lens and the photosensitive element. In a step (B), the original image is converted into a gray scale image. In a step (C), the gray scale image is converted into a binary image according to a critical gray scale value. In a step (D), a boundary contour is obtained according to plural pixels of the binary image higher than or equal to the critical gray scale value. In a step (E), a contour center of the boundary contour is obtained. Then, a step (F) is performed to judge whether an optical axis of the camera lens is aligned with an imaging center of the photosensitive element according to the imaging center and the contour center.

A head mounted device for a helmet includes a connection module, a flexible bracket, a power supply seat and a function module. While the flexible bracket is moved relative to the connection module, a position of the power supply seat relative to the helmet is adjusted. While the function module is moved relative to the power supply seat, an orientation of the function unit is adjusted.

Head mounted device

An electronic device includes a first body, a second body, an electrical connection element, and a hinge structure. The electrical connection element is configured to electrically connect the first body with the second body. The hinge structure is configured to pivot the first body with the second body. The hinge structure includes two mounting bases, two first linking assemblies, and a second linking assembly. Each of the mounting bases is connected to the first body and the second body. The two first linking assemblies are respectively pivoted to the two mounting bases. The second linking assembly is disposed between the two mounting bases, and two opposite terminals of the second linking assembly are movably connected to the two mounting bases respectively. The second linking assembly has a receding space configured to accommodate a portion of the electrical connection element.

Electronic device

An electronic device test system is configured to test functions of an electronic device. The electronic device test system includes: a test computer, configured to execute an electronic device test program; a scanning device, configured to scan a barcode number of the electronic device; and an optical sensor module, configured to detect a connection status of the electronic device and the test computer. When the optical sensor module confirms the connection status, the electronic device test program starts a test function to test the electronic device, records a test result of the electronic device according to the barcode number, and subsequently generates a retest rate according to the test result.

Electronic device test system and method thereof

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.
