  • Patent number: 7338376
    Abstract: A video game distribution network for use in airlines, trains, hotels, cruise ships, set top boxes, cable television systems, satellite and other wireless systems or other communications systems, distributes special purpose game binary image files to general purpose computing/display devices. Software emulators running on the general purpose computing/display devices model the game source platform and interpret and/or compile the game files to provide interactive video game play. Software emulators for emulating a handheld video game platform such as GAME BOY®, GAME BOY COLOR® and/or GAME BOY ADVANCE® on a low-capability target platform (e.g., a seat-back display for airline or train use, a personal digital assistant, a cell phone) may provide any number of features and optimizations to provide high quality graphics and sound that nearly duplicates the game playing experience on the native platform.

  • Publication number: 20070275780
    Abstract: Multiple video game players access an encrypted video game library stored on a shared mass storage device. A multiplexer multiplexes data read from the mass storage device to provide output streams to multiple video game playing units consuming video game instructions. A secure bus communicates video game instructions from the shared mass storage device to each of the video game playing units. Video game software or other entertainment content is distributed to the shared mass storage device via electronic download in multi-level encrypted form. Before being transported, the content is encrypted and then further encrypted. Once the content has been successfully transported, it is decrypted to remove the further encryption layer—leaving the first encryption layer intact for protecting the video game during storage on mass storage at the remote distribution location.

  • Patent number: 7183034
    Abstract: The present invention provides a tandem-type image forming method using a trickle developing system, wherein the average circularity of a toner contained in at least a supplementary developer used for appropriately supplying a developer to a developing device is in the range of 0.940 to 0.980. In the toner, the ratio of the number of particles having an average circularity of 0.970 or greater, in a particle diameter range of a toner circle-equivalent diameter×3/5 or less, is 5% or less, and the ratio of the number of particles having an average circularity of 0.950 or less, in a particle diameter range of a toner circle-equivalent diameter×7/5 or greater, is 10% or less.

  • Patent number: 7024043
    Abstract: After a gray scale image extracting unit converts an input document image to a gray scale image, a multi-code image binary-coding unit converts the image to a binary image having a value in which each pixel indicates either a background area or a plotting area in the image, and outputs the binary image to a binary image recognizing unit. In the multi-code binary-coding unit, a partial area extracting unit extracts one or more partial areas in the gray scale image. A partial image binary-coding unit executes a binary-coding process for each of the partial areas in the gray scale image. A binary image combining unit combines one or more partial binary images and constitutes a binary image of the entire gray scale image.

  • Publication number: 20060009289
    Abstract: A car area network is disposed in a car to enable communications between various devices in the car. An existing consumer electronics device (CED) coupled to the car area network (CAN) performs an existing consumer electronics device function. That existing (CED) is adapted to control various devices coupled to the CAN including video gaming devices. In one example, the adapted CED cooperates with a game server to effect game play. In another example, the adapted CED functions as a virtual video game platform to support play of video games. A multifunction controller transmits control information to the adapted CED via the car area network to permit a car occupant to control the adapted CED to permit the occupant to play a video game using the video game display. One or more audio and/or visual devices coupled to the CAN may also be controlled by commands transmitted from the adapted CED or from the multimedia controller over the CAN.

  • Patent number: 6733944
    Abstract: The present invention provides an image forming process including the steps of: forming a latent image; developing the latent image with a toner to form a toner image; transferring the toner image onto a receiving body; and fixing the toner image to the receiving body, wherein the step of fixing is carried out using a fixing device including a heat-fixing roller, an endless belt, and a pressure member to allow the endless belt to travel around the heat-fixing roller at a given angle such that a nip is produced through which a recording sheet passes, with the pressure member being pressed to distort the heat-resistant elastic layer in the heat-fixing roller, and wherein the toner for developing the electrostatic latent image satisfies predetermined requirements.

  • Patent number: 6731279
    Abstract: An apparatus for determining whether polygons which form objects defined by graphic data generated by CAD intersect with virtually generated light rays. Polygons which are not intersected are removed from the graphic data as unnecessary for the generation of CG data. An apparatus is also described in which path passage points which pass through an animation path within a virtual world are interactively set. If an object exists that interferes with a path that joins adjacent path passage points, an alternate route path which detours around the interfering object is generated. An apparatus is also described in which a path of a moving object is interactively set on a perspective view of the virtual world as viewed from one direction. The position of the set path in the virtual world is calculated, and the position of the path in the direction of viewing is corrected to a position that is removed from an object by a prescribed distance.

  • Patent number: 6701015
    Abstract: A character string extraction apparatus extracts an aggregate of basic components from a document image, such as a binary image, gray scale image, color image, etc., and judges whether each basic component is a character component using an inclusion relationship between the basic components. Then, the character string extraction apparatus extracts an aggregate of character components based on the judgment result and extracts a character string from the aggregate of character components.

  • Patent number: 6587106
    Abstract: A computer graphics apparatus includes a walk-through function to simulate with a computer the concept of walking through a structure such as a building. Display processing time and calculation processing time for one frame of a computer graphic image are improved by an input unit which receives a viewline moving instruction to move a viewline of a computer image. A viewline control unit determines positions and directions of the viewline while a storage unit stores computer graphics data including three-dimensional data of objects, walk-through attribute data and viewline data. An image generation unit then generates images including animated images based on the position of the viewline and the computer graphics data. The resultant images are then displayed on an image display unit.
