Appl. No.:

12/198770

Inventors:

Nenad Nestorovic - Seattle WA, US
Joel E. Hegland - Snohomish WA, US

Assignee:

Microvision, Inc. - Redmond WA

International Classification:

G02B 27/00
G02B 27/01

US Classification:

359601, 359738

Abstract:

Briefly, in accordance with one or more embodiments, an optical relay for a head up display, the optical relay comprises a glare trap having angularly selectivity by being capable of reflecting light having an angle of incidence greater than a first angle, and being capable of transmitting light having an angle of incidence less than a second angle, and a first optic arranged to receive light reflected off the glare trap at an angle of incidence greater than the first angle, and to direct light through the glare trap at an angle of incidence less than the second angle to exit the glare trap.

US Classification:

359601, 359738

Abstract:

An optical relay () includes a glare trap () that in one embodiment has one or more surfaces configured to reflect light impinging the surface () at an angle less than a first angle () relative to a normal line (), and to transmit light impinging the surface () at an angle greater than a second angle () relative to the normal line (). In other embodiments, the glare trap () reflects light impinging at an angle greater than a first angle and transmit light impinging at an angle that is less than a second angle. The separation between the first angle () and second angle () can be on the order of 20 degrees or more, but this angle can be reduced or eliminated when polarized light is used within the optical relay ().

US Classification:

353 69, 353 31, 353 34, 353 38, 353 86, 353119, 349 5

Abstract:

Telecommunication devices each having projection apparatuses capable of projecting ambiently displayed images at locations proximate to the telecommunication devices on surfaces that are substantially parallel to planes formed by the telecommunication devices are described herein. The telecommunication devices also have logic configured to provide predistorted images to the projection apparatuses, the predistorted images appearing without distortion when projected by the projection apparatuses on the surfaces in the ambiently displayed images.

Appl. No.:

09/128954

Inventors:

JOHN R. LEWIS - BELLEVUE WA, US
NENAD NESTOROVIC - SEATTLE WA, US

International Classification:

G09G005/00

US Classification:

345/007000

Abstract:

A display apparatus includes an image source, an eye position detector, and a combiner, that are aligned to a user's eye. The eye position detector monitors light reflected from the user's eye to identify the pupil position. If light from the image source becomes misaligned with respect to the pupil, a physical positioning mechanism adjusts the relative positions of the image source and the beam combiner so that light from the image source is translated relative to the pupil, thereby realigning the display to the pupil. In one embodiment, the positioner is a piezoelectric positioner and in other embodiments, the positioner is a servomechanism or a shape memory alloy.

Assignee:

Microvision, Inc. - Bothell WA

International Classification:

G09G003/36

US Classification:

345/087000, 359/353000, 359/356000

Abstract:

A display apparatus includes an IR or other light source that produces light at a first wavelength that is modulated according to a desired image. The modulated light is then applied to a phosphor that converts the light to a second wavelength in the visible range. In one embodiment, the image source is a scanned light beam display that scans an IR light beam onto an image intensifier tube of a night vision goggle. In other embodiments, the image source is a LCD having an IR back light or a FED panel that emits electrons directly into a microchannel accelerator plate of the night vision goggles. In still another embodiment, the image source emits visible or ultraviolet light onto a phosphor that emits light of a different wavelength in response.
