    • A tool for calibrating a non-contact tonometer (NCT) comprises a body having a mating feature configured for removably mounting the body on the nosepiece or on the measurement head of the NCT, a pressure sensor carried by the body and arranged to receive an air pulse discharged by the NCT to provide a pressure signal in response to the air pulse, and a radiation emitter carried by the body, wherein the radiation emitter provides a pseudo-applanation event when the pressure signal reaches a predetermined level that is detectable by the NCT as though an actual corneal applanation had taken place. In one embodiment, the mating feature includes a mounting orifice for receiving a portion of the nosepiece. In another embodiment, the mating feature includes a pair of mounting pins sized for receipt by a corresponding pair of mounting holes in the measurement head of the NCT.

    • This disclosure relates to a hold down mechanism which is particularly adapted to apply a preselected hold down pressure on an element. It employs a bar which is pivotally mounted on a support member with the bar having a hold down surface thereon so positioned that when the bar is pivoted in a selected direction the hold down surface will engage the element in clamping relation and further pivoting of the bar in the same direction will result in the shifting of the pivot point for the bar from the pivot member to the hold down surface. The pivot member is spring loaded for lifting movement at this time with an associated spring pack providing for a controlled loading by the hold down surface against the element. A movable cam member having a wedge shaped lower end moves between a cam follower carried by the arm and a fixed cam follower to effect the controlled pivoting of the bar.
    • 本公开涉及一种压紧机构,其特别适于在元件上施加预选的压紧压力。 它采用杆,其可枢转地安装在支撑构件上,杆具有在其上的压紧表面,其定位成使得当杆沿所选方向枢转时,压紧表面将以夹紧关系与元件接合并进一步枢转杆 在相同的方向上将导致杆的枢轴点从枢转构件移动到保持表面。 弹簧加载弹簧,用于提升此时的运动,相关联的弹簧组件通过压紧表面抵抗元件的受控加载。 具有楔形下端的可移动凸轮件在由臂承载的凸轮从动件和固定凸轮从动件之间移动,以实现杆的受控枢转。
