Abstract: A Rugged portable device comprises: a base, a cover pivotally connected to the base, a first antenna unit, a second antenna unit, and a control unit. The first antenna unit and the second antenna unit are respectively disposed at an edge of the cover and an edge of the base, and the first antenna unit and the second antenna unit respectively have a near-field antenna and a far-field antenna. When the cover pivots relative to the base and is close to the base, the near-field antenna disposed at the cover and the near-field antenna disposed at the base generate a near-field communication (NFC) sensing signal and the near-field communication sensing signal is transmitted to the control unit. Therefore, the control unit sets up one of functions in the rugged portable device. For instance, the control unit switches off and/or switches on the far-field antenna or a peripheral unit (a keyboard or a camera).

Abstract: A button structure of a wireless transceiver and a manufacturing method thereof are provided. The button structure includes a housing, a first spring-back button, and a second spring-back button. The first spring-back button are integrally formed by double injection molding respectively. The first spring-back button and the second spring-back button are connected with the housing through insert injection molding. Thus, a manufacturer may produce the first spring-back button and the second spring-back button by a double injection molding machine in advance, and then combine the first spring-back button and the second spring-back button with the housing by the insert injection molding, so as to make the wireless transceiver with buttons of different colors.

Abstract: A charging apparatus for laptop computer with multiple-batteries is used in a first battery unit and a second battery unit. The charging apparatus comprises a micro controller unit; a first charging switch unit electrically connected to the micro controller unit; a second charging switch unit electrically connected to the micro controller unit; and a charging unit electrically connected to the first charging switch unit and the second charging switch unit. The micro controller unit controls the charging unit charging the first battery unit and the second battery unit via controlling the first charging switch unit and the second charging switch unit. The charging apparatus charges multi-batteries simultaneously.

Abstract: A handwriting board with a liquid crystal display (LCD) includes a wireless Universal Serial Bus (USB) unit, a USB hub unit, a USB/Video Graphic Array (VGA) conversion unit, a LCD driver unit, a LCD unit, a touch pad controller unit and a touch pad unit. When a user writes on the touch pad unit, the content written by the user is transmitted from the touch pad controller unit and the USB hub unit 204 to the wireless USB unit, which transmits the written content to a computer for processing. The processed written content is then transmitted to a projector and the wireless USB unit. Thereby, the written content can be displayed on the LCD unit.

Abstract: A monitor clamping device includes a first board having multiple first hooks and a second board having multiple second hooks, the monitor is clamped between the first and second hooks. Multiple first slots are defined in the second board and multiple first guide plates are connected to the first board. The first guide plates movably extend through the first slots. Multiple second guide plates are connected to the second board and engaged with the first guide plates when the first guide plates are moved to a lower end of the first slots. A resilient unit is connected between the first and second board so as to adjust the distance between the first and second hooks. The monitor clamping device can clamp different size monitors.
