Inventors:

David Eldridge - Salinas CA, US

International Classification:

H01R 13/627

US Classification:

439357

Abstract:

Disclosed herein is an apparatus that relates to a device useful in integrated chip (IC) testing apparatus. More particularly, the device is an adjustable clamp assembly which allows a variety of different sized IC's to be used with a single piece of test equipment. The clamp assembly includes a frame, a base and a plurality of clamps. Each clamp is movably connected to the base to allow movement in the x-y directions and each of the clamps includes an z-direction adjustment mechanism. Additionally, the device according to this invention also includes an adapter having opposed adapters which are designed for compatible mating with a mechanized handlers. In an exemplary embodiment, the adapter has a suspension system designed for quiet mechanized handling of the IC while being held by the clamp assembly.

International Classification:

G01R 31/02

US Classification:

324758, 324755

Abstract:

Disclosed herein is a suspension system and adjustment mechanism for an integrated chip held in a clamping or similar assembly and a related method for same. The suspension system Includes a pressure plate member adapted to fit compatibly within the clamp assembly. A hinge assembly applies and releases pressure through the pressure plate member. The hinge assembly has a first open position where pressure is released and a second closed position where pressure is applied. A spring member between the pressure plate member and the hinge assembly has predetermined travel limits controlling the amount of pressure to be applied. In an exemplary embodiment of the invention disclosed herein the suspension system includes an adjustment mechanism which adjusts to the pressure to a fine degree. The adjustment mechanism includes a housing which applies and releases pressures in response to the turning of a control knob. The control knob is connected to a gear apparatus within the housing which responds to the movement of the control knob by moving the housing.

Abstract:

The eye examination kiosk and method may comprise a structure for rotating and/or translating ophthalmologic examination devices such as an auto-refractor, an auto-keratometer, a corneal topographer, a fundus camera, an external photo camera, a perimeter, a lensmeter, a specular microscope, a retinal and external eye imager, an Optical Coherence Tomographer (OCT), or a non-contact tonometer into a position such that they may be used for examination of a patient. The kiosk outer shell may comprise an opening allowing the ophthalmologic examination equipment to perform eye examinations of a patient. Eye examination results are transmitted to a remote location where they are read by a physician, who transmits examination findings and recommendations for follow up treatment to the patient. The results may include the identity of qualified physicians who practice geographically near the patient, or who are qualified to treat a patient for a specific condition indication.
