  • Patent number: 9076368
    Abstract: Image generation systems and image generation methods are described. In one aspect, an image generation system includes an attachment system configured to secure the image generation system to a head of a user in a position to be observed by the user; an illumination system having an exit pupil located at infinity and configured to emit light; a light modulator configured to receive the light from the illumination system and to selectively reflect at least some of the received light which corresponds to an image; a control system coupled with the light modulator and configured to access data content regarding the image, to generate a plurality of control signals according to the accessed data content, and to output the control signals to the light modulator to control the selective reflection of at least some of the received light; and an output optical system configured to direct the selectively reflected light towards an observer's eye to be observed by the observer.

  • Patent number: 8982014
    Abstract: Image generation systems and image generation methods are described. According to one aspect, an image generation system includes an imaging system configured to transmit light towards an observer's eye to form a plurality of pixels of an image upon the retina of the observer's eye at a moment in time; and a control system coupled with the imaging system and wherein the control system is configured to access data content regarding the image, to generate a plurality of control signals according to the accessed data content, and to output the control signals to the imaging system to control the transmission of the light by the imaging system towards the observer's eye to form the plurality of pixels of the image upon the retina of the observer's eye at the moment in time.

  • Patent number: 8528383
    Abstract: A pressure sensor and method of sensing pressure is disclosed. An fluid port is coupled to a substrate. A first microchannel within the substrate is in fluid communication with the fluid port. The first microchannel includes a first compressible fluid, a first incompressible fluid and at least one first meniscus. A second microchannel within the substrate is in fluid communication with the fluid port. The second microchannel includes a second compressible fluid, a second incompressible fluid and at least one second meniscus. A pressure of the first meniscus and/or the second meniscus is determined.
