    • The invention relates to adjusting an input signal level of a Sigma-Delta converter (1020). A control signal (S AGC,control ) indicative of an input signal level to said Sigma-Delta converter (1020) is generated, and the input signal level to said Sigma-Delta converter (1020) is adjusted in dependence of said control signal (S AGC,control )- The control signal (S AGC,control ) is generated as a signal indicating an operating condition of said Sigma-Delta converter (1020). In this way, internal signals from the Sigma-Delta converter can be used to determine the state of the Sigma-Delta converter, i.e. whether it is operating within its operational input range or not, and whether it is close to the limits of the operational input range. This provides a simple, but accurate guidance of an automatic gain control upstream of the Sigma-Delta converter.
    • 本发明涉及调整Σ-Δ转换器(1020)的输入信号电平。 产生指示到所述Σ-Δ转换器(1020)的输入信号电平的控制信号(S> AGC,控制),并且调整到所述Σ-Δ转换器(1020)的输入信号电平 根据所述控制信号(S> AGC,控制) - 产生控制信号(S> AGC,控制)作为指示所述Σ-Δ的操作条件的信号 转换器(1020)。 这样,Sigma-Delta转换器的内部信号可用于确定Sigma-Delta转换器的状态,即它是否在其运行输入范围内运行,以及是否接近运行的极限 输入范围。 这提供了对Sigma-Delta转换器上游的自动增益控制的简单但准确的指导。

    • The present invention provides a cell line including a first reporter gene arranged to express an assayable first gene product, expression of the first reporter gene being AP-1 mediated, and a second reporter gene arranged to express a second assayable gene product, expression of the second reporter gene being mediated by NF kappa B. Thus the present invention provides a convenient one cell line-based assay system which can be used to rapidly test a large number of compounds for potential anti-inflammatory activity. According to a further aspect of the invention there is provided a method of testing a compound for both AP1 and NF kappa B inhibitory activity, the method comprising providing cells in accordance with the first aspect of the invention, stimulating AP1 and NF kappa B activity in the cells and contacting the cells with the compound to be tested and monitoring expression of the first and second gene products wherein inhibition of AP1 expression of the first gene product, and inhibition of NF kappa B mediated expression of the second gene product is indicative that the compound has both AP1 and NF kappa B-inhibitory activity.
    • 本发明提供一种细胞系,其包括布置成表达可测定的第一基因产物的第一报道基因,介导的AP-1的第一报道基因的表达,以及排列成表达第二可测定基因产物的第二报道基因, 第二报告基因由NFκB介导。因此,本发明提供了一种方便的一种基于细胞系的测定系统,其可用于快速测试大量化合物用于潜在的抗炎活性。 根据本发明的另一方面,提供了测试AP1和NFκB抑制活性化合物的方法,所述方法包括提供根据本发明第一方面的细胞,其刺激AP1和NFκB活性 细胞并使细胞与待测化合物接触并监测第一和第二基因产物的表达,其中抑制第一基因产物的AP1表达和抑制NFκB介导的第二基因产物的表达表明, 化合物具有AP1和NFκB抑制活性。
