Appl. No.:

13/184186

Inventors:

Xiaoyu Miao - Sunnyvale CA, US

Assignee:

Google Inc. - Mountain View CA

International Classification:

G02F 1/1335

US Classification:

349 11, 349 9

Abstract:

An eyepiece for a head mounted display includes an illumination module, an end reflector, a viewing region, and a polarization rotator. The illumination module includes an image source for launching computer generated image (“CGI”) light along a forward propagating path. The end reflector is disposed at an opposite end of the eyepiece from the illumination module to reflect the CGI back along a reverse propagation path. The viewing region is disposed between the illumination module and the end reflector. The viewing region includes a polarizing beam splitter (“PBS) and non-polarizing beam splitter (“non-PBS”) disposed between the PBS and the end reflector. The viewing region redirects the CGI light from the reverse propagation path out of an eye-ward side of the eyepiece. The polarization rotator is disposed in the forward and reverse propagation paths of the CGI light between the viewing region and the end reflector.

Abstract:

Example methods and systems for displaying one or more indications that indicate (i) the direction of a source of sound and (ii) the intensity level of the sound are disclosed. A method may involve receiving audio data corresponding to sound detected by a wearable computing system. Further, the method may involve analyzing the audio data to determine both (i) a direction from the wearable computing system of a source of the sound and (ii) an intensity level of the sound. Still further, the method may involve causing the wearable computing system to display one or more indications that indicate (i) the direction of the source of the sound and (ii) the intensity level of the sound.

US Classification:

359618, 359629, 359633, 359630, 345 8

Abstract:

An optical system includes a display panel, an image former, a viewing window, a proximal beam splitter, and a distal beam splitter. The display panel is configured to generate a light pattern. The image former is configured to form a virtual image from the light pattern generated by the display panel. The viewing window is configured to allow outside light in from outside of the optical system. The virtual image and the outside light are viewable along a viewing axis extending through the proximal beam splitter. The distal beam splitter is optically coupled to the display panel and the proximal beam splitter and has a beam-splitting interface in a plane that is parallel to the viewing axis. A camera may also be optically coupled to the distal beam splitter so as to be able to receive a portion of the outside light that is viewable along the viewing axis.

International Classification:

C40B 50/14

US Classification:

506 30, 977773

Abstract:

Methods for optically trapping and manipulating micro- and nano-sized particles by using light to induce localized surface plasmon resonance on metallic surface of a substrate. The method includes the steps of contacting a substrate with a medium having particles suspended therein; focusing a beam of coherent light onto the substrate such that the beam induces surface plasmon resonance; and trapping at least one of the suspended particles using a light induced dielectrophoresis force generated by the surface plasmon resonance.

Assignee:

GOOGLE INC. - Mountain View CA

International Classification:

G02B 26/10

US Classification:

3592051, 3592121

Abstract:

An optical apparatus includes an image source, a scanning mirror, an actuator, and a scanning controller. The image source outputs an image by simultaneously projecting a two-dimensional array of image pixels representing a whole portion of the image. The scanning mirror is positioned in an optical path of the image to reflect the image. The actuator is coupled to the scanning mirror to selectively adjust the scanning mirror about at least one axis. The scanning controller is coupled to the actuator to control a position of the scanning mirror about the at least one axis. The scanning controller includes logic to continuously and repetitiously adjust the position of the scanning mirror to cause the image to be scanned over an eyebox area that is larger than the whole portion of the image.

A wearable computing system may provide a view of a real-world environment of the wearable computing system. The wearable computing system may image at least a portion of the view of the real-world environment in real-time to obtain a real-time image. The wearable computing system may receive at least one input command that is associated with a desired manipulation of the real-time image. The at least one input command may be a hand gesture. Then, based on the at least one received input command, the wearable computing system may manipulate the real-time image in accordance with the desired manipulation. After manipulating the real-time image, the wearable computing system may display the manipulated real-time image in a display of the wearable computing system.

International Classification:

G02B 27/01

US Classification:

359630

Abstract:

An eyepiece for a head mounted display includes an illumination module, an end reflector, a viewing region, and a polarization rotator. The illumination module provides CGI light along a forward propagation path within the eyepiece. The end reflector is disposed at an opposite end of the eyepiece from the illumination module to reflect the CGI light back along a reverse propagation path within the eyepiece. The viewing is disposed between the illumination module and the end reflector and includes an out-coupling polarizing beam splitter (“PBS”). The out-coupling PBS passes the CGI light traveling along the forward propagation path and redirects the CGI light traveling along the reverse propagation path out of an eye-ward side of the eyepiece. The polarization rotator is disposed in the forward and reverse propagation paths between the out-coupling PBS and the end reflector.
