    • An acceleration measuring device is disclosed, for use as a gravimeter or gradiometer for example. The device has a support and a proof mass, connected to each other by at flexures allowing displacement of the proof mass relative to the support. The support defines a space for displacement of the proof mass. The device is configured so that the modulus of the gradient of the force-displacement curve of the proof mass decreases with increasing displacement, for at least part of the force-displacement curve. This is the so-called anti-spring effect. The resonant frequency of oscillation of the proof mass is determined at least in part by the orientation of the device relative to the direction of the force due to gravity. The proof mass is capable of oscillating with a resonant frequency of 10 Hz or less. The proof mass has a mass of less than 1 gram.
    • 公开了用作例如重力仪或梯度计的加速度测量装置。 该装置具有支撑和证明质量,通过挠曲相互连接,允许证明块相对于支撑件的位移。 支撑件定义了用于检测质量块的位移的空间。 该装置被构造成使得在至少部分力 - 位移曲线中,证明质量块的力 - 位移曲线的梯度的模量随着位移的增加而减小。 这就是所谓的抗弹力效应。 至少部分地由装置相对于由于重力引起的力的方向的取向来确定证明物质的振动的共振频率。 检测质量能够以10Hz或更小的谐振频率振荡。 证明质量块的质量小于1克。

    • A measurement apparatus is disclosed, for measuring a response of a sensor device such as a microcantilever which deflects in response to an analyte. The measurement apparatus includes a pixel lated array of detector elements ( e.g. digital camera) and a substantially monochromatic light source. The camera is arranged to capture a series of images of the deflectable element, each image including an interference pattern provided by interference between a sample beam and a reference beam, wherein the phase of one of the sample beam and the reference beam is shifted as between one image in the series of images and the next image in the series of images. This allows the deflection profile of the microcantilever to be calculated. Also disclosed is a sensor apparatus for use with the measurement apparatus. The sensor apparatus provides the microcantilever between a support and a cover with a sealing element interposed between and sealing with the support and with the cover.
    • 公开了一种测量装置,用于测量响应于分析物偏转的微型悬臂梁等传感器装置的响应。 测量装置包括检测器元件(例如数字照相机)和基本单色光源的像素排列阵列。 相机被布置成捕获可偏转元件的一系列图像,每个图像包括由样本光束和参考光束之间的干涉提供的干涉图案,其中样本光束和参考光束之一的相位在 一系列图像中的一个图像和一系列图像中的下一个图像。 这允许计算微悬臂梁的偏转轮廓。 还公开了一种与测量装置一起使用的传感器装置。 该传感器装置在支架和盖之间提供微型悬臂,其间插入有密封元件,并与支架和盖子密封。
