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.

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.

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.
