Abstract: An infusion device includes an infusion pump and an infusion tube assembly. The infusion tube assembly includes a first tube body connected to the infusion pump, a tube joint structure having first, second and third tube joints, a second tube body, and a clamping device on the second tube body. The clamping device is to clamp the second tube body. An infusion method includes instructing the infusion pump to perform an infusion operation. When bubbles are detected in a liquid in the infusion tube assembly, the infusion pump is instructed to stop the infusion operation and a bubble alarm is generated. After the infusion pump stops the infusion operation, it is determined whether a pressure of the liquid first drops to a first pressure value and then rises to a second pressure value. If yes, a rinsing operation is performed.

Abstract: A wireless communication system and a method for switching a base station (BS) thereof are provided. In the present invention, a globe positioning system (GPS) of a mobile apparatus is capable of obtaining a location information about the mobile apparatus. On receiving the location information transmitted from the mobile apparatus, a server end apparatus switches to a corresponding BS of a serving area where the mobile apparatus is located so as to serve the mobile apparatus.

Abstract: An electronic apparatus having dual displays includes a casing, a circuit board, an electronic-paper display and a non-electronic-paper display. The casing has a first side and a second side. The circuit board is disposed in the casing. The electronic-paper display is disposed on the first side of the casing and connected to the circuit board. The non-electronic-paper display is disposed on the second side of the casing and connected to the circuit board. The electronic-paper display can be used for displaying a text document, and the non-electronic-paper display can be used for displaying high quality image data, e.g. a streaming media. Based on the attribute of a file, a user can select an appropriate display for displaying the file so as to make good use of the electronic apparatus.

Abstract: A spark plug comprising a housing, a ceramic insulator and a sleeve is provided. The housing has an inner cavity while the ceramic insulator encloses a central electrode. The ceramic insulator is disposed inside the inner cavity and maintain from the housing with a gap. The sleeve is provided enclosing an inner wall of the housing and corresponds to an opening of the inner cavity. The level of an edge surface of the housing corresponding to the opening of the inner cavity is disposed higher than the level of an edge surface of the central electrode, and the level of the center electrode is also higher than the level of the edge surface of the ceramic insulator.

Abstract: A portable navigation device is disclosed. The portable navigation device includes a global positioning module, a user interface, a destination obtaining means, a status obtaining means and a route generating means. The global positioning module generates a current position of the portable navigation device based on a global positioning signal. The destination obtaining means obtains a destination from the user interface. The status obtaining means obtains a user status from the user interface. The route generating means generates a suggested route based on the current position, the destination and the user status.

Abstract: An antenna system for a GPS receiver that includes a casing and a micro processor. The antenna system includes at least two antenna units, a micro controller, a switching unit and a signal processor. The antenna units are used for receiving a satellite signal. Each of the antenna units owns a signal-receiving direction for guiding the satellite signal. The micro controller determines an optimal signal-receiving direction for receiving the satellite signal according to a use mode and generates a control signal for choosing a specific antenna from the antenna units. The switching unit is coupled to the antenna units and can define a receiving route for enabling the specific antenna to receive the satellite signal according to the control signal.
