Assignee:

Topcon Medical Laser Systems, Inc. - Santa Clara CA

International Classification:

A61B 3/00

Abstract:

Methods and apparatuses for an ophthalmic imaging system are provided. An ophthalmic illumination system with a micro-display projector based head-up display is provided. In accordance with an embodiment, a first optical element is configured to direct light from a light source upon an eye to be examined. A micro-display projector is configured to generate a micro-display image including information associated with the eye to be examined. A third optical element is configured to receive reflected light from the eye resulting from the light directed upon the eye, receive the micro-display image, and transmit at least a portion of the reflected light and at least a portion of light from the micro-display image.

International Classification:

H05K 9/00

US Classification:

174350, 296021

Abstract:

A method and apparatus for EMI protection is disclosed. Particularly, the present invention is directed to an article of manufacture for electromagnetic interference shielding comprising a cylindrically-shaped sleeve constructed of a conductive fabric adapted to provide electromagnetic interference shielding by conducting at least a portion of electromagnetic radiation, wherein the cylindrically-shaped sleeve is made by rolling a piece of conductive fabric into a cylindrical shape such that opposing sides of the piece of conductive fabric are joined together resulting in the cylindrically-shaped sleeve having a seam at a junction of the opposing sides. In one embodiment, opposing sides of the piece of conductive fabric are sewn together.
