    Abstract: Designs of extremely high efficiency solar cells are described. A novel alternating bias scheme enhances the photovoltaic power extraction capability above the cell band-gap by enabling the extraction of hot carriers. When applied in conventional solar cells, this alternating bias scheme has the potential of more than doubling their yielded net efficiency. When applied in conjunction with solar cells incorporating quantum wells (QWs) or quantum dots (QDs) based solar cells, the described alternating bias scheme has the potential of extending such solar cell power extraction coverage, possibly across the entire solar spectrum, thus enabling unprecedented solar power extraction efficiency. Within such cells, a novel alternating bias scheme extends the cell energy conversion capability above the cell material band-gap while the quantum confinement structures are used to extend the cell energy conversion capability below the cell band-gap. Light confinement cavities are incorporated into the cell structure in order to allow the absorption of the cell internal photo emission, thus further enhancing the cell efficiency.

    Abstract: Methods for virtual clothes fitting when shopping online are presented. The online shopper prepares and keeps a 3D volumetric scan or point cloud of their body. Shoppers upload their 3D volumetric body scan to an online store. The online store stores the 3D volumetric scan of the clothing it offers for sale on their online shop. The online store has the processing capabilities to fit the 3D body scan provided by the shopper with the 3D volumetric scan of clothing it offers for sale on their online shop. Once the 3D volumetric data of the offered clothing item is digitally fitted by the online store on the 3D volumetric scan of the offered clothing item, the 3D volumetric data of the offered clothing fitted on the created “Virtual Mannequin” of the shopper is sent back to shopper to view and examine. On the screen of their computing platform, the shopper can then view and examine 3D images received (uploaded) from the online shop of the selected clothing item fitted on their virtual mannequin and make a buy decision.

    Abstract: Methods and systems for light field image encoding and decoding are disclosed. According to some embodiments, scene metadata and input light field images associated with a scene are received. A first encoding operation is performed on the scene metadata and input light field images to generate reference images, reference disparity information, and an order of reference views. A second encoding operation is performed based on the reference images and reference disparity information to output light field encoded data. The light field encoded data includes the encoded reference images, the encoded reference disparity information, and the order of reference views. The light field encoded data is transmitted.

    Abstract: A wearable display system that includes an optical lens element in optical communication with an electronic display device for displaying images to a viewer. An eye position sensor, head position or pose sensor, and gaze/head pose prediction means are provided. The gaze/head pose prediction means is configured to process a sensed position of the viewer's eyes as one or more observation vectors through a sequentially updated model of the HVS to predict and estimate (multiple frames) the gaze parameters (direction and depth or pose). A host processor is configured to input and output display data, which may comprise light field data, to and from the system to a Cloud processor to provide displayed images to the viewer wherein the displayed images are optimized to match the viewer's human visual system.
