Abstract: A detachable computer includes a host, an expansion base, a first latch structure and a second latch structure. The first and second latch structures are disposed on a back surface of the host and an engaging surface of an engaging plate of the engaging plate respectively. One of each pair of the first and second latch structures includes a clamp portion and another one includes a clip member. The host is engaged with the engaging plate by latching the clip member with the clamp portion. The clip member includes a frame and a clip column. The clip column extends from a first sidewall to a second sidewall of the frame. The clip member is latched into the clamp portion through the clip column. Two sides of the clamp portion substantially abut against the first and second sidewalls when the clip column is latched into the clamp portion.

Abstract: A base for a point of sale system includes a baseboard and a first connection base. The point of sale system further comprises a mainframe, which includes one or more connection sockets, a case with a mainframe tenon and a touch panel. The baseboard has a baseboard tenon separably connected to the mainframe tenon. In addition, the first connection base has a first extending position and a first connection position, and the first connection base has a first connection base sliding unit and one or more than one connection plugs. The connection plugs are at the same side of the first connection sliding unit which is opposite to the connection sockets, and the amount of the connection plugs and the connection sockets are the same, and, on the other hand, the relative disposition of the connection plugs and the connection sockets are corresponsive. Further, the first baseboard sliding unit slidably connects to the first connection base sliding unit.

Abstract: A cooling module for using in a metal housing of a calculation processing apparatus is disclosed. The cooling module is adapted to cool at least one heat source inside the metal housing. The cooling module comprises a first heat conduction plate, a second heat conduction plate and a heat conduction device, wherein the first heat conduction plate covers the heat source, the second heat conduction plate connects to the metal housing, and the heat conduction device is adapted to connect the first heat conduction plate with the second heat conduction plate. After the heat generated by the heat source is absorbed by the first heat conduction plate, the heat is transmitted to the second heat conduction plate through the heat conduction device, and will be dissipated uniformly throughout the metal housing.

Abstract: A control module co-constructed with a car audio apparatus has a Bluetooth module, a car audio apparatus, a sound switch and a sound control circuit. The sound switch is disposed inside the car audio apparatus and connected with the sound signal processor. It is used to choose a sound signal sent from the Bluetooth earphone or the car audio apparatus and output the sound signal via the speaker. The sound control circuit is disposed inside the car audio apparatus and connected with the sound switch. When the Bluetooth earphone is plugged into the socket of the car audio apparatus, the sound switch will silence the car audio apparatus automatically and output the sound signal sent from the Bluetooth earphone via the speaker. When the Bluetooth earphone is taken out from the socket, the car audio apparatus will serve as a common audio apparatus.

Abstract: A wireless earphone with a built-in mobile communications module and a dial-up method of the same are proposed. The mobile communications module is used to automatically answer an incoming call. A wireless electronic dial-up device is used for dial-up communications. The wireless earphone comprises a mobile communications module, a digital signal processor, an earphone, a microphone and a wireless communications module. The mobile communications module is used to receive a first remote signal and emit a first reply modulation signal. The digital signal processor is connected to the mobile communications module and used for processing digital signals. The earphone is connected to the digital signal processor. The microphone is connected to the digital signal processor. The wireless communications module is also connected to the digital signal processor, and is used to receive a second remote signal and emit a second reply modulation signal.

Abstract: The present invention has a hollow stem, a printed circuit board, a cursor control unit, a control knob unit and a function key. The printed circuit board is located within the hollow stem, and the cursor control unit is located within the hollow stem and near a tip of the stylus. The control knob unit is positioned on the printed circuit board and has a turning knob protruding outwardly from the stem. The turning knob is rotatable and resilient so that data is input by rotation and pressure. The function key is positioned on the printed circuit board and protrudes outwardly from the stem. Thus, the present invention provides a stylus that is operable, convenient and ergonomic and integrated with function key to facilitate fast switching functions.

Abstract: The present invention provides a wireless hands-free apparatus with a sound-absorbing function. The hands-free apparatus has improved talking quality when used with a bluetooth earphone. The hands-free apparatus has an earphone with a built-in wireless communication module therein, a membrane sound capture device for receiving the input of the sound wave and a connecting line connected between the earphone and the membrane sound capture device. The membrane sound capture device can receive the user's sound wave and propagate the sound by the wireless communication module of the earphone through the connecting line.

Abstract: A device for automatic tire inflation and tire pressure display has a tire pressure measurement unit, a tire temperature sensor (a thermometer) and a gradienter for measuring the tire balance. The tire pressure measurement unit has a tire pressure measurement unit, a voltage regulating circuit of power source, a microprocessor control unit, a wireless transceiving module and an inflation/deflation control component. The tire pressure measurement unit measures the tire pressure value of a tested tire. The tire pressure value is then wirelessly displayed on a display unit in a vehicle so that the user can know the present status of a tire. The user can also maneuver a function key to select an operation according to the displayed data and send this message to the tire room to execute inflation or deflation of the tire.
