  • Publication number: 20190346968
    Abstract: An interactive environment image may be projected onto one or more surfaces, and interaction with the projected environment image may be detected within a three-dimensional space over the one or more surfaces. The interactive environment image may be a three dimensional image, or it may be two dimensional. An image is projected onto a surface to provide a visual representation of a virtual space including one or more of the virtual objects, which may be spatially positioned. User interaction with the projected visualized representation of the virtual space may be detected and, in response to user interaction, the projected visualized representation may be changed.

  • Patent number: 10425814
    Abstract: An iris biometric recognition module includes technology for capturing images of an iris of an eye of a person, whether the person is moving or stationary. The iris biometric recognition technology can perform an iris matching procedure for, e.g., authentication or identity purposes, by comparing a digital iris image to a reference iris image and, if the digital and reference iris images match, authenticating a person as authorized to access a first device and transmitting a wireless communication from the first device to a second device.

  • Publication number: 20170365473
    Abstract: Graphite-based devices with a reduced characteristic dimension and methods for forming such devices are provided. One or more thin films are deposited onto a substrate and undesired portions of the deposited thin film or thin films are removed to produce processed elements with reduced characteristic dimensions. Graphene layers are generated on selected processed elements or exposed portions of the substrate after removal of the processed elements. Multiple sets of graphene layers can be generated, each with a different physical characteristic, thereby producing a graphite-based device with multiple functionalities in the same device.

  • Patent number: 9437425
    Abstract: Methods for forming integrated graphite-based structures with interconnections between leads and graphene layers are provided. A substrate is patterned to form a plurality of elements on the substrate. A trench separates a first element from an adjacent element in the plurality of elements. A lead is deposited on a side wall of the first element, and a layer from the top of the first element is removed to expose a portion of the lead. Both the deposition of the lead and removal of a layer from the top of the first element are conducted before generation of graphene layers on the top of the first element and the bottom of the trench. Thus, an integrated graphite-based structure having spatially isolated but electrically connected graphene layers is formed.

  • Publication number: 20150349061
    Abstract: Methods for forming graphite-based structures (302, 304), in which a substrate is patterned to form a plurality of elements (104, 208) on the substrate (102), are provided. A trench separates a first element from an adjacent element in the plurality. The surface of the first element and the surface of the trench (i) are respectively characterized by different first and second elevations and (ii) are separated by a side wall of the first element. Orthogonal projections of the surface of the first element and the surface of the trench onto a common plane are contiguous or overlapping. In the method, a first graphene layer (302) on the entire first surface and a second graphene layer (304) on the entire second surface are concurrently generated. The second graphene layer has a thickness that is less than a difference between the first and second elevations. Thus, a graphite-based structure having isolated first and second graphene layers is formed.

  • Patent number: 9172041
    Abstract: An integrated graphene-based structure comprises an N-dimensional array of elements formed on a surface of a substrate. The N-dimensional array of elements includes a plurality of rows. Each respective row in the plurality of rows comprises a corresponding plurality of elements formed along a first dimension. Each element in the corresponding plurality of elements comprising at least one graphene stack and separated from an adjacent element along the first dimension by a first average spatial separation thereby resulting in a first periodicity in lateral spacing along the first dimension. Each respective row in the plurality of rows is separated from an adjacent row along a second dimension by a second average spatial separation, thereby resulting in a second periodicity in lateral spacing along the second dimension. The N-dimensional array exhibits a set of characteristic electromagnetic interference properties in response to electromagnetic radiation incident on the N-dimensional array.

  • Patent number: 9133853
    Abstract: Apparatus is provided featuring a bearing cartridge in combination with a pedestal. The bearing cartridge may be configured to be coupled to a pumping assembly combination and having a predetermined centerline. The pedestal may be configured with an axial channel to receive and support the bearing cartridge and allow the bearing cartridge to slide therein. The bearing cartridge and the pedestal are configured to couple together substantially at or above the centerline of the bearing cartridge in order to reduce center height requirements of the apparatus, where the center height is defined as the distance between the centerline of the bearing cartridge and the bottom surface of the pedestal supporting the bearing cartridge. The apparatus takes the form of a pump or pumping assembly, arrangement or combination, including a slurry-type pump or a centrifugal pump.
