摘要： A compressor includes a housing; a compressor liner positioned within the housing and at least partially defining a first cylinder with an inlet and an outlet; a piston positioned within the first cylinder and configured to compress air flowing into the first cylinder through the inlet; a cylinder head at least partially defining the first cylinder; and a sealing assembly for sealing an interface between the compressor liner and the cylinder head. The sealing assembly includes a ring seal at an interface between the cylinder head and the compressor liner; a vent port on an opposite side of the ring seal from the first cylinder; and a vent tube extending between the vent port and the inlet such that air leaking through the ring seal from the first cylinder flows through the vent port, through the vent tube, and into the inlet.

摘要： An optical system includes an active focus element that maintains an image in focus over a range of object distances. The active focus element and aperture stop are positioned such that the image scale and the image spatial resolution are also invariant (or at least have a reduced sensitivity) with respect to object distance.
摘要翻译：光学系统包括主动聚焦元件，其在对象距离的范围内保持图像焦点。定位有源聚焦元件和孔径光阑使得图像尺度和图像空间分辨率相对于物体距离也是不变的（或至少具有降低的灵敏度）。

摘要： A rapid iris acquisition, tracking, and imaging system can be used at longer standoff distances and over larger capture volumes, without the active cooperation of subjects. Eye reflections from the subjects' eyes are used to steer a high resolution camera to the eyes in order to capture images of the irises. A circular deformable minor driven by one or more annular forces can be used to focus the camera. A circular mirror substrate is mounted by its circumference onto a minor mount and driven by an annular drive element that contacts the minor substrate along a ring. If the annular drive element has a certain diameter relative to the circumference of the mirror substrate, the mirror substrate will be deformed in the shape of a sphere.
摘要翻译：快速虹膜采集，跟踪和成像系统可以在更长的距离距离和更大的捕获体积下使用，而不需要主体的积极配合。来自受试者的眼睛的眼睛反射被用于将高分辨率相机引导到眼睛以便捕获虹膜的图像。可以使用由一个或多个环形力驱动的圆形可变形小块来聚焦相机。圆形反射镜基板由其圆周安装到次安装座上，并由环形驱动元件驱动，环形驱动元件沿环形接触次要基板。如果环形驱动元件相对于镜面基板的圆周具有一定的直径，则反射镜基板将以球形变形。
