Abstract: A magnetic sensor and the electronic compass using the same are provided. The magnetic sensor is configured to sense magnetic components along each axis of a first reference coordinate system, and the first reference coordinate system is associated with the magnetic sensors. When a sensitivity of the magnetic sensor for an axis A of the first reference coordinate system is different from a sensitivity for another axis, the magnetic component Am along the axis A is corrected using the following equation: Am=Am(n?1)×(Wa?1)/Wa+Am(n)×1/Wa??(A) Therefore, Am(n) designates a current measured magnetic component along the axis A, Am(n?1) designates a previous measured or calculated magnetic component along the axis A, and Wa is a weight value.

Abstract: The present invention provides a platelet-containing composition prepared by contacting platelets with a medium for preserving. The medium comprises anticoagulant, cryoprecipitate and thrombin. The present invention also provides a method for long-term preservation of platelets, comprising the steps of: (a) adding an anticoagulant, cryoprecipitate, thrombin in normal saline; (b) adding a platelet-containing medium into the solution formed in step (a); and (c) lyophilizing the platelet-containing solution formed in step (b). Moreover, the present invention yet provides a medium for preserving non-nucleus cells.

Abstract: A portable computer has a main frame, a liftable monitor set, and at least a pivot joint connected to the main frame and the liftable monitor set. The monitor set has a first video display, a second video display, and a panel disposed between the first video display and the second video display. The main frame has a keyboard and a cursor device.

Abstract: An apparatus and a method for preventing particle contamination in a plasma etch chamber equipped with a middle chamber by residual etchant gas is provided. In the apparatus, a bypass exhaust conduit is provided for connecting between a middle chamber cavity and a main chamber cavity such that when a pump means is turned on to evacuate the main chamber cavity, any residual etchant gas in the middle chamber cavity can be rapidly evacuated without the danger of causing metal corrosion in the middle chamber cavity. Any chamber contamination caused by the metal corrosion can thus be avoided.
