  • Publication number: 20230251494
    Abstract: A near eye display system having an image display panel, a prism assembly comprising a first and second element and a structure such as a eye wear glasses frame. The front and rear surfaces of the first and second elements are aligned and bonded to form the prism assembly. A partially-reflective coating is applied to the interface of the first and second elements to define a beam-splitter interface. The image display panel is disposed near an upper optical region such as a refracting surface of the first element. The lower edge of the second element opposite the beam-splitter interface is a coated reflective surface mirror. The display panel, the optical region and the optically reflective surface are configured to provide compactness and to avoid the break of symmetry. The system accommodates large inter pupil distance (IPD) variation and left/right eye scanning motion.

  • Patent number: 10845591
    Abstract: A split exit pupil heads-up display (HUD) system and method. The HUD system architecture makes use of a split exit pupil design method that enables a modular HUD system and allows the HUD system viewing eye-box size to be tailored while reducing the overall volumetric aspects. A single HUD module utilizes a micro-pixel imager to generate a HUD virtual image with a given viewing eye-box size. When integrated together into a single HUD system, a multiplicity of such HUD modules displaying the same image enables an integrated HUD system to have an eye-box size that equals the same multiple of the eye-box size of a single HUD module. The brightness of the integrated HUD system is maintained while the eye-box size becomes multiple size of the eye-box of a single module. The integrated HUD system can be comprised of multiplicity of single HUD modules to scale the eye-box size to match the intended application while maintaining system brightness.

  • Patent number: 10585290
    Abstract: Wearable augmented reality display systems are provided. One or a plurality of emissive display elements are embedded in the bridge area of an eyeglass frame. The lenses are provided with a set of transmissive diffractive optical elements and partially reflective diffractive optical elements. The display outputs are directed toward the lens elements whereby the diffractive elements in turn direct the outputs toward the eye-boxes of the viewer.

  • Patent number: 10539791
    Abstract: Split exit pupil (or split eye-box) heads-up display (HUD)systems and methods are described. The described HUD system methods make use of a split exit pupil design method that enables a modular HUD system and allows the HUD system viewing eye-box size to be tailored while reducing the overall HUD volumetric aspects. A HUD module utilizes a high brightness small size micro-pixel imager to generate one or more HUD virtual images with a one or a plurality of given viewing eye-box segment sizes. When integrated together into a HUD system, a multiplicity of such HUD modules displaying the same image would enable such an integrated HUD system to have an eye-box size that is substantially larger than the eye-box size of a HUD module. The resultant integrated HUD system volume is substantially volumetrically smaller than a HUD system that uses a single larger imager.

  • Patent number: 10012402
    Abstract: Disclosed is a top-fill humidifier easy to wash and without water leakage. The humidifier comprises a single-piece body having a hollow chamber with a wall and bottom; and an isolator removably assembled in the chamber to divide the chamber into a storage sub-chamber between the isolator and the wall of the chamber and a vaporizing sub-chamber between the isolator and the bottom of the chamber. In such a humidifier, the isolator divides the chamber in the body into a storage chamber and a vaporizing chamber, which may solve the problem of water leakage and facilitate the washing of the humidifier.

  • Patent number: 9930272
    Abstract: Spatio-temporal light field cameras that can be used to capture the light field within its spatio temporally extended angular extent. Such cameras can be used to record 3D images, 2D images that can be computationally focused, or wide angle panoramic 2D images with relatively high spatial and directional resolutions. The light field cameras can be also be used as 2D/3D switchable cameras with extended angular extent. The spatio-temporal aspects of the novel light field cameras allow them to capture and digitally record the intensity and color from multiple directional views within a wide angle. The inherent volumetric compactness of the light field cameras make it possible to embed in small mobile devices to capture either 3D images or computationally focusable 2D images. The inherent versatility of these light field cameras makes them suitable for multiple perspective light field capture for 3D movies and video recording applications.
