    • The invention relates to transgenic non-human animals capable of producing heterologous antibodies and transgenic non-human animals having inactivated endogenous immunoglobulin genes. In one aspect of the invention, endogenous immunoglobulin genes are suppressed by antisense polynucleotides and/or by antiserum directed against endogenous immunoglobulins. Heterologous antibodies are encoded by immunoglobulin genes not normally found in the genome of that species of non-human animal. In one aspect of the invention, one or more transgenes containing sequences of unrearranged heterologous human immunoglobulin heavy chains are introduced into a non-human animal thereby forming a transgenic animal capable of functionally rearranging transgenic immunoglobulin sequences and producing a repertoire of antibodies of various isotypes encoded by human immunoglobulin genes. Such heterologous human antibodies are produced in B-cells which are thereafter immortalized, e.g., by fusing with an immortalizing cell line such as a myeloma or by manipulating such B-cells by other techniques to perpetuate a cell line capable of producing a monoclonal heterologous antibody. The invention also relates to heavy and light chain immunoglobulin transgenes for making such transgenic non-human animals as well as methods and vectors for disrupting endogenous immunoglobulin loci in the transgenic animal.
    • 本发明涉及能够产生具有失活的内源免疫球蛋白基因的异源抗体和转基因非人动物的转基因非人动物。 在本发明的一个方面,内源性免疫球蛋白基因被反义多核苷酸和/或针对内源性免疫球蛋白的抗血清抑制。 异源抗体由非人动物种类的基因组中通常不存在的免疫球蛋白基因编码。 在本发明的一个方面,将含有未经排列的异源人免疫球蛋白重链序列的一个或多个转基因引入非人动物中,从而形成能够功能重排转基因免疫球蛋白序列并产生编码的各种同种型抗体的所有组成的转基因动物 通过人免疫球蛋白基因。 这样的异源人抗体是在B细胞中产生的,其后被永生化,例如通过用永生化细胞系如骨髓瘤进行融合,或通过其它技术操纵这样的B细胞以使能够产生单克隆异源抗体的细胞系 。 本发明还涉及用于制备这种转基因非人动物的重链和轻链免疫球蛋白转基因以及用于破坏转基因动物内源性免疫球蛋白基因座的方法和载体。

    • Angular motion sensor signals from an inertial integrating rate sensor are provided to a translation device that provides a translated output signal that is substantially the same as an input sensor signal translated in frequency by an amount equal to a reference frequency. The translated output signal is provided to a phase detector that provides a detector output signal indicative of phase differences between the translated output signal and a feedback signal. The phase detector output signal is provided to a voltage controlled oscillator which provides an oscillator output signal that is related to the phase detector output signal. The voltage controlled oscillator signal is provided to a counter that is capable of providing a count that is representative of a highly resolved measure of angular rotation. In addition, the counter is capable of providing the feedback signal that is related to the variable frequency output signal.
    • 来自惯性积分速率传感器的角运动传感器信号被提供给翻译装置,该翻译装置提供与经频率转换等于参考频率的量的输入传感器信号基本上相同的转换输出信号。 转换的输出信号被提供给相位检测器,该相位检测器提供指示转换的输出信号和反馈信号之间的相位差的检测器输出信号。 相位检测器输出信号被提供给压控振荡器,其提供与相位检测器输出信号相关的振荡器输出信号。 压控振荡器信号被提供给能够提供表示高度分辨的角度旋转度量的计数的计数器。 此外,计数器能够提供与可变频率输出信号相关的反馈信号。
