    • Measurement of small oscillatory movements of an irregular surface (12) involves the production of a speckle pattern therefrom by coherent light illumination, and the arrangement of a photodetector (14) for direct response to such pattern, variations in photodetector output component at the frequency of the surface movement representing that movement. Another, stationary, illuminated irregular surface (13) can be involved to produce a speckle interference pattern for response of the photodetector (14) thereto and, in the case where the two surfaces (12, 13) are closely adjacent, a single beam can be used to illuminate the first and other surfaces predominantly and by stray light, respectively. This common beam illumination can be used in prior speckle interferometry. The first surface (12) can be an eardrum oscillated by a sound wave, suitably of swept frequency or impulse form, with detection of the photodetector variations respectively being in synchronous manner or by Fourier analysis, respectively.
    • 不规则表面(12)的小振荡运动的测量涉及通过相干光照射产生散斑图案,以及用于直接响应于这种图案的光电检测器(14)的布置,光电检测器输出部件的频率变化 表面运动代表这种运动。 可以涉及另一个静止的照明不规则表面(13)以产生用于光电检测器(14)对其的响应的散斑干涉图案,并且在两个表面(12,13)紧密相邻的情况下,单个光束可以 用于分别照亮第一和其他表面和杂散光。 这种共同的光束照明可以用于先前的散斑干涉测量。 第一表面(12)可以是由适当地扫掠频率或脉冲形式的声波振荡的鼓膜,分别以同步方式或通过傅立叶分析检测光电检测器变化。

    • An oral airway includes a first component having a first guiding surface and a second component having a second guiding surface. The first component and the second component are adapted to be removably coupled together such that the first guiding surface and the second guiding surface collectively define and encompass an interior passage through the oral airway that is dimensioned to direct, for example, a fiber-optic scope or an endotracheal tube extending through the interior passage for tracheal intubation. The first and second components are configured to be decoupled and independently removed from a patient's mouth without disrupting an endotracheal tube that has been extended through the conduit for tracheal intubation. The first and second components may be maintained in coupled disposition by an interlocking mechanical structure. The first and second components also may be maintained in coupled disposition by magnetism.
