    摘要: An apparatus for determining the distance between the pupils to yield values representative of lenses properly aligned with the patient's pupils when mounted in the sockets of a spectacle frame. The apparatus consists of a calibration device having spaced fixed marking for placement in the plane of lenses, a camera with a zooming arrangement for taking an image of the subject, and a computer for generating parametric values relevant to the lenses to be ground as a function of the distance between the camera and the subject, the position of the zooming device at the time the image is taken, and the size of the image on the focal plane of the camera.

    摘要: A seat belt buckle having a release button for a latch slidably mounted on a frame, an ejector for an insert tongue and at least one connecting element. The connecting element is shiftable between a working position, in which it makes a connection between the ejector and the release button, and a resting position in which it breaks the connection between the ejector and release button. A dislocator is provided on the frame, which dislocates the connecting element from the resting position into the working position when the ejector is shifted out of place.
