  • Patent number: 10636193
    Abstract: A virtual reality (VR) or augmented reality (AR) head mounted display (HMD) includes various image capture devices that capture images of portions of the user's face and body. Through image analysis, points of each portion of the user's face and body are identified from the images and their movement is tracked. The identified points are mapped to a three dimensional model of a face and to a three dimensional model of a body. From the identified points, animation parameters describing positioning of various points of the user's face and body are determined for each captured image. From the animation parameters and transforms mapping the captured images to three dimensions, the three dimensional model of the face and the three dimensional model of the body is altered to render movement of the user's face and body.

    Abstract: The present invention discloses compositions and methods for generating engineered catalysts and synthesizing semiconducting single wall carbon nanotubes using the catalysts Carbon nanotubes (CNTs). The CNTS are either metallic or semiconducting, with diameters controlled by an engineered catalyst to selectively synthesizes the semiconducting CNT. The engineered catalyst consists of two types of metals, a high melting point metal and an active transition metal. Each of the metals remains solid state during a growth of semiconducting CNTs, and each is present as nanoparticles, having sizes between 0.5 nm and 10 nm. The ratio of the high melting point metal with respect to the active transition metal is preferably between 1:0.25 and 1:10.

  • Publication number: 20200014533
    Abstract: A continuous variable quantum key distribution system comprises a transmitter and a receiver. The first quantum signal has a first polarization and is associated with first quadrature components and the second quantum signal has a second polarization and is associated with second quadrature components. The receiver receives the quantum signals transmitted by the transmitter via a quantum communication channel; estimates a channel matrix representing the polarization rotation of the first and second polarization caused by the quantum communication channel; modifies the received first and second quantum signals on the basis of the polarization rotation; and uses the modified received first and second quantum signals for generating a secret key.

  • Patent number: 10529113
    Abstract: A virtual reality (VR) or augmented reality (AR) head mounted display (HMD) includes various image capture devices that capture images of portions of the user's face. Through image analysis, points of each portion of the user's face are identified from the images and their movement is tracked. The identified points are mapped to a three dimensional model of a face. From the identified points, a blendshape vector is determined for each captured image, resulting in various vectors indicating the user's facial expressions. A direct expression model that directly maps images to blendshape coefficients for a set of facial expressions based on captured information from a set of users may augment the blendshape vector in various embodiments. From the blendshape vectors and transforms mapping the captured images to three dimensions, the three dimensional model of the face is altered to render the user's facial expressions.

  • Patent number: 10509467
    Abstract: A virtual reality (VR) or augmented reality (AR) head mounted display (HMD) includes multiple image capture devices positioned within the HMD to capture portions of a face of a user wearing the HMD. Images from an image capture device include a user's eye, while additional images from another image capture device include the user's other eye. The images and the additional images are provided to a controller, which applies a trained model to the images and the additional images to generate a vector identifying a position of the user's head and positions of the user's eye and fixation of each of the user's eyes. Additionally, illumination sources illuminating portions of the user's face include in the images and in the additional images are configured when the user wears the HMD to prevent over-saturation or under-saturation of the images and the additional images.
