    摘要： A latching system for a circuit breaker is arranged to actuate a trip unit and interrupt circuit current upon occurrence of a short circuit or an overcurrent condition. The latching system employs an armature having a recess formed therein and a cradle having a cradle tip arranged to releasably engage the recess. A thermal magnetic trip unit is depicted within the circuit breaker for the purposes of detecting overcurrent conditions through the electric path. During current transport through the circuit breaker, the current is thermally sensed by means of the bimetal and magnetically sensed by means of the magnet. The armature rotates against the return bias of a compression spring to release the cradle tip from the recess and allow counterclockwise rotation of the contact arm. The rotation of the contact arm causes the separation of the movable and fixed contacts under the urgence of a mechanism spring.

    摘要： A head-mounted, eye-movement, measurement system is provided with an optically flat glass laminated visor through which the observer views the external scene. Mounted so as to be vertically spaced from one side of the eye's optic axis is an eye tracker module for recording the observer's eye-movement relative to the head, principally by measuring the position of the pupil and corneal reflex, by reflecting near infrared light to and from the observer's eye vis-a-vis the front surface of the visor. Mounted so as to be vertically spaced on the opposite side of the eye's optic axis is a field-of-view camera which records the external scene viewed by the observer by reflecting external scene light from the back side of the visor. The distances and angular relationship of the visor, camera and eye are controlled to eliminate parallax from the field-of-view camera while also providing a stable arrangement permitting wide-angle scene viewing and accurate recordal of eye movements.
