Abstract
Official abstract text for this publication.
A space suit helmet capable of meeting the demands of future space suit helmet display requirements in a decoupled-helmet, helmet-mounted design with sufficient eye relief is provided. A display system and a redirecting assembly are coupled together and mounted to the helmet. The display system generates an image and the redirecting assembly orients the image with respect to a predetermined valid eye location volume within the helmet.
First claim
Opening claim text (preview).
What is claimed is: 1. A helmet suitable for use in space, comprising: a display system mounted to the helmet that is configured to generate an image, the display system comprising a relay lens assembly configured to create an intermediate virtual image; a processor module configured to command the display system to generate the image; and a redirecting assembly coupled to the display system for orienting an image with respect to a static predetermined valid eye location volume within the helmet, wherein the redirecting assembly comprises, (1) a fixed focusing lens assembly configured to create a virtual image based on the intermediate virtual image, the virtual image focused at a static predetermined virtual image distance, the static predetermined virtual image distance being independent of ambient scenery, and (2) a first mirror oriented to redirect the intermediate virtual image toward the predetermined valid eye location volume. 2. The helmet of claim 1 , wherein the fixed focusing lens assembly is located at a static first predetermined distance from the predetermined valid eye location volume. 3. The helmet of claim 2 , wherein the display system and redirecting assembly are enclosed within an externally mounted housing. 4. The helmet of claim 1 , wherein the fixed focusing lens assembly is located at a static second predetermined distance from the predetermined valid eye location volume. 5. The helmet of claim 4 wherein: the fixed focusing lens assembly is located within the helmet; and the display system and first mirror are located in housing mounted on an external surface of the helmet. 6. The helmet of claim 1 , wherein the image comprises a three dimensional, moving image.
