    • A piezoelectric transformer (10) consisting of a single-crystal elongated plate (12) with electrodes (20, 26). A pair of driving sections (22) are formed on two opposite end regions of the plate (12). A receiving section (24) is formed on a central region of the plate (12). The plate (12) is operated in an even harmonic vibrational mode with the driving sections (22) operating in a transverse extensional mode and the receiving section (24) operating in a length extensional mode. Driving signals (46, 48) applied to the driving sections (22) are at the resonant frequency of the plate (12). The gain of the transformer (10) is adjustable by shifting the relative phase of the driving signals (46, 48) applied to the respective driving sections (22).
    • 一种由具有电极(20,26)的单晶细长板(12)组成的压电变压器(10)。 一对驱动部分(22)形成在板(12)的两个相对的端部区域上。 接收部分(24)形成在板(12)的中心区域上。 板(12)以均匀谐波振动模式操作,其中驱动部分(22)以横向延伸模式操作,并且接收部分(24)以长度延伸模式操作。 施加到驱动部分(22)的驱动信号(46,48)处于板(12)的共振频率。 变压器(10)的增益可通过移动施加到相应驱动部分(22)的驱动信号(46,48)的相对相位来调节。

    • A method and an apparatus for determining leakage volume of fluid in transportation pipelines are provided. The method comprises: obtaining the negative pressure wave signals detected by at least two pressure sensors arranged on the pipeline; determining the pressure signal at the leakage location based on the negative pressure wave signals; determining the leakage rate during a leakage period based on the pressure signal at the leakage location according to a leakage model; and determining the leakage volume of the fluid in the pipeline based on the leakage rate and the leakage period. The apparatus provided corresponds to the method described above. By using the method and apparatus described above, the leakage volume of the transportation pipelines can be obtained to help understand the leakage profile of the pipelines and thus reduce losses.

    • The invention provides a molecular affinity clamp. The architecture of the affinity clamp is modular with two biorecognition modules, each capable of binding a target motif. The first biorecognition module has a recognition domain that possesses inherent or natural specificity for the target motif. The second biorecognition module also has a recognition domain that binds the motif. The two biorecognition modules are tethered together either directly, e.g., via a peptide bond between the two modules, or indirectly, e.g., via a linker moiety or linker. The invention further provides a novel affinity ligand which is specifically bound by the molecular affinity clamps of the invention.
