  • Patent number: 7884775
    Abstract: A multi-band antenna for use, for example, in a wireless communications network, employs multi-resonant microstrip dipoles that resonate at multiple frequencies due to microstrip “islands.” Gaps in the microstrips create an open RF circuit except for desired frequencies. At a desired frequency, RF energy sees a gap as a short circuit between an island and the rest of a dipole antenna, thus, resonating at the desired frequency. In one instance, the multi-band antenna includes a first, second, third, and fourth dipole elements. Gaps between the first and third dipole elements and the second and fourth dipole elements are sufficiently small that the first, second, third, and fourth dipole elements form a second dipole having a corresponding dipole wavelength longer than that of the first dipole.

During the navigation session, the display screen is zoomed-out and a magnifying area may appear on the display screen. The user interface enables the user to scroll the zoomed-out display screen by dragging the magnifying area towards an edge of the display screen to find a desired item of information. The display screen may be a display screen of a digital device (e.g., portable computer, personal computer, a cellular telephone, a digital watch, etc). The user may terminate a navigation session by removing the pointer from the display screen.

  • Patent number: 7884811
    Abstract: A hand-holdable, durable digital writing and sketching device or assembly having rugged construction that houses an on-board camera with a view through an optical window of a writing surface brought in view by a user moving the device. The device is rugged, sealed, and is capable of withstanding dropping, water submersion, abrasive incursions, and resistance to chemical and fungal degradation. The optical window and optic channel to the camera is protected by a durable and replaceable light-transmitting shield that provides a sealed barrier to the environmental elements harmful to the functioning of the device. The writing and sketching device oscillates between a stowed and a deployed state. The deployed state includes the camera being in view the writing surface and the stowed state includes the camera being either masked from viewing the writing surface or aimed internally from viewing the writing surface.

  • Patent number: 7884817
    Abstract: An API is provided that enables programmability of a 3D chip, wherein programming or algorithmic elements written by the developer can be downloaded to the chip, thereby programming the chip to perform those algorithms. A developer writes a routine that is downloadable to a 3D graphics chip. There are also a set of algorithmic elements that are provided in connection with the API that have already been programmed for the developer, that are downloadable to the programmable chip for improved performance. Thus, a developer may download preexisting API objects to a 3D graphics chip. A developer adheres to a specific format for packing up an algorithmic element, or set of instructions, for implementation by a 3D graphics chip. The developer packs the instruction set into an array of numbers, by referring to a list of ‘tokens’ understood by the 3D graphics chip. This array of numbers in turn is mapped correctly to the 3D graphics chip for implementation of the algorithmic element by the 3D graphics chip.

  • Patent number: 7884819
    Abstract: By merging or adding the color contributions from objects intersected by secondary rays, the image processing system may accumulate color contributions to pixels from objects intersected by secondary rays as the further color contributions are determined. Furthermore, by associating a scaling factor of color contribution with objects and with secondary rays which intersect the objects, color contributions due to secondary ray/object intersections may be calculated at a later time than the color contribution to a pixel from original ray/object intersection. Consequently, it is not necessary for a vector throughput engine or a workload manager to wait for all secondary ray/object intersections to be determined before updating the color of a pixel.

  • Patent number: 7884820
    Abstract: Interactive relighting with dynamic reflectance involves relighting a graphical scene with dynamic changes to the reflectance(s) in the graphical scene. A graphical scene may include source radiance, regions having reflectances, a surface spot, incident radiation from the source radiance at the surface sport, an incident direction, a viewing direction, exit radiance, and so forth. In an example embodiment, a graphical scene is relighted based on at least one adjusted reflectance of the graphical scene using an incident radiance at a surface spot that is separated into respective incident radiance components corresponding to different respective numbers of interreflections in the graphical scene. In another example embodiment, a graphical scene is relighted based on at least one adjusted reflectance of the graphical scene using a tensor representation for a reflectance of a surface spot with the tensor representation being segmented into three adjustable factors for lighting, viewing, and reflectance.

  • Patent number: 7884822
    Abstract: A game apparatus includes a first LCD and a second LCD, and on the first LCD, a two-dimensional game screen including objects positioned in a two-dimensional coordinate is displayed. When a two-dimensional coordinate of a specific object out of the objects positioned in the two-dimensional coordinate satisfies a predetermined condition, a three-dimensional coordinate of each of the objects is calculated on the basis of the two-dimensional coordinate of each of the objects. The object is modeled in the calculated three-dimensional coordinate, moved by a predetermined animation, and then shot by a virtual camera. Accordingly, a game screen of an image (animation) of the three-dimensional virtual space shot by the virtual camera is displayed on the second LCD.

  • Patent number: 7884823
    Abstract: Game data is rendered in three dimensions in the GPU of a game console. A left camera view and a right camera view are generated from a single camera view. The left and right camera positions are derived as an offset from a default camera. The focal distance of the left and right cameras is infinity. A game developer does not have to encode dual images into a specific hardware format. When a viewer sees the two slightly offset images, the user's brain combines the two offset images into a single 3D image to give the illusion that objects either pop out from or recede into the display screen. In another embodiment, individual, private video is rendered, on a single display screen, for different viewers. Rather than rendering two similar offset images, two completely different images are rendered allowing each player to view only one of the images.

  • Patent number: 7884825
    Abstract: An edge function is computed from two vertex coordinates given by a rendering target line. Gradient determination is then performed on the edge function, and the functions representing two shift lines that are formed by translating the rendering target line in the y-axis direction or x-axis direction depending on the angle formed by the rendering target line and the x-axis of the rendering plane coordinate system by 0.5d and ?0.5d will be computed, where d denotes the width of one pixel. Then, the number of subpixels included in a parallelogram, which has four points of the starting points and ending points of the two shift lines as vertices, is acquired so as to determine the pixel value of each pixel based on the number.
