Abstract: A device and a method for analyzing an analyte in a liquid sample are provided. The device comprises a detecting chamber included in a detection device for containing a detecting element; a liquid sample transferring chamber; and a film with small pores disposed between the detecting chamber and liquid sample transferring chamber. When the detection device is inserted into a liquid sample collecting chamber, the liquid sample in the collecting chamber enters the liquid sample transferring chamber but cannot enter the detecting chamber via the film with small pores. When a piston is inserted into the liquid sample transferring chamber, the piston forces a part of liquid sample in the liquid sample transferring chamber to enter the detecting chamber via the film with small pores. Using the device and the method can determine an analyte in a sample quantitatively and can complete the detection in one step.

Abstract: A device for reading an assay test result on a test carrier comprises: a light-emitting element (5) for emitting and irradiating light onto corresponding one or more zones of the test carrier (3); a light-blocking element (12) for blocking the light mirror-reflected by the test carrier (3) from being irradiated on a photodetector (7); and a window (10), through which the light emitted from the light-emitting element (5) is irradiated onto the corresponding zones of the test carrier (3). In one preferred embodiment, the positions of the light-emitting element (5), the light-blocking element and the window (10) meet the function of S3?>2*S7?S7*S2/S1, where S1 represents the vertical distance between the light-emitting element and the window; S2 represents the vertical height of the light-blocking element; S3 represents the vertical distance between the light-blocking element and the light-emitting element; and S7 represents the length of the window.

Abstract: An antenna that is capable of accommodating both IEEE 802.11b/g traffic and IEEE 802.11n traffic is provided. The antenna includes a ground plane member, a plurality of inverted F slot antenna elements disposed at equidistant positions along a periphery of the ground plane member, and a plurality of slot elements disposed at equidistant positions along the periphery of the ground plane member is provided. First and second slot elements can be disposed on respective first and second sides of each inverted F slot antenna element, and each inverted F slot antenna element can operate in a first frequency band and in a second frequency band.

Abstract: A method of forming an aluminum-copper alloy film capable of preventing copper precipitation includes: (a) loading a wafer into a PVD tool comprising a vacuum transfer chamber that couples to a cool down chamber, an aluminum-copper sputter deposition process chamber and an anti-reflection coating process chamber; (b) sputter-depositing a first layer of aluminum-copper alloy onto the wafer in the aluminum-copper sputter deposition process chamber to a first thickness; (c) inter-cooling the wafer and the first layer of aluminum-copper alloy in the cool down chamber; (d) sputter-depositing a second layer of aluminum-copper alloy onto the cooled down first layer of aluminum-copper alloy in the aluminum-copper sputter deposition process chamber to a second thickness; and (e) repeating steps (b) to (d) until a third thickness of the aluminum-copper alloy is reached.
