    摘要： A relay is formed by a magnet system containing a wound coil body, an L-shaped core arranged axially therein, an L-shaped armature and a base element with terminal elements. Stationary and moving contact elements are arranged between the base element and the magnet system. The armature is mounted with the free end of its transverse leg at the free end of the longitudinal leg of the core. The armature is secured through a U-shaped armature spring wrapping around the armature. The spring is secured with one arm at the longitudinal leg of the armature and a second arm is inserted in a recess between the coil body and the core. The actuation of the moving contact elements is provided via a slide coupled to the armature. This slide is hooked to the armature by spring tabs of the armature spring at opposing sides of the armature through snap latches formed at the ends of the side arms of the slide.

    摘要： Apparatus is provided for determining the topography, thickness, and fiber orientation of the nerve fiber layer at the fundus of the eye by measuring the polarization shift induced in a return beam of polarized light which is reflected at the ocular fundus from an incident beam of a known polarization state. A corneal polarization compensator effectively cancels the birefringent effects of the cornea and other portions of the eye anterior to the fundus, so that clinically meaningful results are produced.

    摘要： Means and Method are provided for determining both the topography and the thickness of the nerve fiber layer at the fundus of the eye by measuring the polarization shift of the reflected probing light. The technique is greatly enhanced in the accuracy of its results by the utilization of a corneal polarization compensator, which lies at the heart of the invention.
