Abstract: A wireless power transmission device includes a main body and a transmitter coil plate. The transmitter coil plate is disposed within the main body. The transmitter coil plate includes a coil plate body, a first transmitter coil structure, and a second transmitter coil structure. The first transmitter coil structure is disposed on a top surface of the coil plate body, and swirled along a first direction. The second transmitter coil structure is disposed on a bottom surface of the coil plate body, and swirled along a second direction. When the transmitter coil plate is magnetized, the magnetic flux generated by the transmitter coil plate is increased. Consequently, the wireless charging efficiency is enhanced.

Abstract: A multicolor illumination keyboard includes a light-emitting element, a color filter and plural keys. The plural keys are located above the light-emitting element. The color filter is arranged between the plural keys and the light-emitting element. After a source light emitted by the light-emitting element passes through the color filter, plural color lights are generated. The plural color lights are outputted from the plural keys. Consequently, the plural keys are illuminated in a multicolor manner.

Abstract: A touch pen includes a main body, a connector, a first conductive pen tip, a second conductive pen tip and a switching module. The connector is disposed within the main body, and located at a first end of the main body. The first conductive pen tip and the second conductive pen tip are detachably coupled with the connector. According to a result of judging whether the connector is coupled with the first conductive pen tip or the second conductive pen tip, the switching module controls the operation mode of the touch pen. When the first conductive pen tip is coupled with the connector, the touch pen is in an active operation mode under control of the switching module. When the second conductive pen tip is coupled with the connector, the touch pen is in a passive operation mode under control of the switching module.

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.

The wireless charging module is used for wirelessly charging an electronic device. The solar charging module is used for charging the power module or providing electricity to the wireless charging module. When the controller detects that an electricity quantity percentage of the power module is lower than a predetermined value, the controller controls the solar charging module to charge the power module. When the electronic device is in communication with the input device, the controller controls the solar charging module to the provide electricity to the wireless charging module, and the electronic device is wirelessly charged by the wireless charging module if the electronic device is within a charging range.

Abstract: A keyboard with height-adjustable keys is provided. The keyboard includes a key supporting plate, the keys and a movable plate. Each key includes a supporting element. Moreover, plural bulges are disposed on the supporting element. The movable plate is disposed under the key supporting plate. The key is fixed on the key supporting plate. The key is connected with the key supporting plate through the supporting element. Moreover, the plural bulges are penetrated downwardly through the key supporting plate and inserted in the movable plate. While the movable plate is moved, the bulges are pushed and the key is moved toward the key supporting plate with the supporting element. Consequently, the height of the key is lowered.

Abstract: A close-type speaker leak test system includes a first chamber, a second chamber, a third chamber, a fourth chamber, a vacuum generator, and a differential pressure gauge. Firstly, a negative pressure value of the first chamber and the second chamber is generated by the vacuum generator. A standard close-type speaker is placed within the third chamber, and the first chamber and the third chamber are in communication with each other. An under-test close-type speaker is placed within a fourth chamber, and the second chamber and the fourth chamber are in communication with each other. A pressure difference value between the third chamber and the fourth chamber is measured by the differential pressure gauge. If the pressure difference value is larger than a predetermined value, the under-test close-type speaker has the leak. Consequently, the misjudgment is reduced, and the testing efficiency is enhanced.
