Abstract: A flexible circuit board capable of transmitting high frequency signals with reduced attenuation includes two outer wiring boards enclosing an inner wiring board. The inner wiring board includes a first conductive wiring layer and a first substrate layer. The first conductive wiring layer includes a signal line and two ground lines on both sides of the signal line. The first substrate layer covers a side of the first conductive wiring layer and defines first through holes which expose the signal line. Each of the two outer wiring boards includes a second substrate layer and a second conductive wiring layer. The second substrate layer abuts the inner wiring board and defines second through holes aligning with the first through holes, to partially surround the signal line with air of very low dielectric constant. A method for manufacturing the flexible circuit board is also disclosed.

Abstract: A vane adjustment device in an air register includes a front vane connector pivotably connected to a front vane and a rear vane connector pivotably connected to a rear vane. The front vane connector includes a sliding member substantially perpendicular to a longitudinal direction of the front vane and the rear vane connector includes a first joint. The first joint is movably connected to the sliding member to enable a linear movement of the sliding member relative to the first joint.

Abstract: A method for determining telomerase activity using primer extension followed with real time PCR quantification is disclosed. The method of the present invention provides a rapid, sensitive and accurate measurement for telomerase activity in a biological sample. In one embodiment, the method includes the steps of: adding the biological sample to a reaction tube containing a first reaction mixture having a first primer and nucleoside triphosphates, a second reaction mixture having a second primer and a DNA polymerase, and a wax layer that separates the first reaction mixture from the second reaction mixture; incubating the biological sample with the first reaction mixture; admixing the extension product with the second reaction mixture; amplifying and quantifying the extension product using real-time PCR and a control template. In another embodiment, the detection method includes an in situ primer extension step that allows the production of the extension product within an intact cell.
