  • Patent number: 6231440
    Abstract: There is provided a computer game apparatus for executing a game in which a character moves through virtual space displayed on a predetermined display by a operation of a operating unit, comprising: a memory storing a game program having movement modes of the character in accordance with distance between the character and another character within the virtual space; and a controller executing the game program and controlling the movements of the character according to the movements modes. By way of example, a first movement mode of the character when the distance between the two characters is within a predetermined distance is set in the game program, and this first movement mode is, for instance, one of the characters moving at high speed in an arc around the other character with a predetermined angle.

  • Patent number: 6213879
    Abstract: Serial transmission data is divided into an odd-numbered bit sequence and an even-numbered bit sequence. Each bit of the odd-numbered bit sequence data is distributed respectively between pulses of a first pulse sequence signal having a constant interval, thereby forming a first pulse sequence signal (SDCKA). Each bit of the even-numbered bit sequence data is distributed respectively between pulses of a second pulse sequence signal having a constant interval, thereby forming a second pulse sequence signal (SDCKB). The respective time axes are adjusted such that the clock component of the first pulse sequence signal is located in the data section of the second pulse sequence signal, and the clock component of the second pulse sequence signal is located in the data section of the first pulse sequence signal. Data is transmitted using these adjusted first and second pulse sequence signals (SDCKA, SDCKB).

  • Patent number: 6200138
    Abstract: A game display method displays a driving game which permits characters to be present in a city and can prevent cruel images of collisions with characters. Characters in a dangerous area are intentionally moved away from a motorbike B. Those H1, H2 of the characters behind the motorbike B as viewed in a moving direction of the motorbike B are intentionally moved away from a current position 01 of the motorbike B, a position of the center of the motorbike B. Those H3, H4, H5 of the characters in front of the motorbike B as viewed in the moving direction of the motorbike B are intentionally moved toward the back of the motorbike B, i.e., directions normal to a straight line interconnecting the position 01 of the center of the motorbike B and the characters H3, H4, H5. The characters H3, H4, who are forward left of the motorbike B, are moved left, and the character Hr, who is forward right, is moved right.

  • Patent number: 6155923
    Abstract: Videogame systems and methods are provided to enhance the capability of the videogame system controller and data storage to provide graphic character element storage and processing. A display list technology utilizes an intentionally generated, location-specific vertical interrupt to implement a routine to modify or to alter existing graphical character elements. A second technique involves the definition of a small portion of the graphics map which is displayed differently than the balance of the graphics map because the stored priority bit is expressed in the defined area, but suppressed and replaced in all other areas. The third technique employs a virtual character element library to map the character elements appearing on the display, and recognizes available space within the video random access memory character element storage to provide a dynamic memory space.

  • Patent number: 6151026
    Abstract: An image processing apparatus and an image processing method are proposed for the high speed generation of a model, such as a plane picture in animation, for which an outline is drawn. In the image processing apparatus, for using computer graphics to generate a polygon model in three-dimensional coordinate space, a first model, for which the normal vectors of polygons are directed outward, and a second model, in which the first model is included and for which the normal vectors of polygons are directed inward, are synthesized as a single model. The direction of the normal vector of a polygon is employed in the hidden surface removal process to determine whether the polygon should be displayed. That is, when the normal vector of a polygon includes an element extended in the direction of the viewpoint, the pertinent polygon is displayed; but when the normal vector of a polygon does not include an element extended in the direction opposite to that of the viewpoint, the pertinent polygon is not displayed.

  • Patent number: RE36738
    Abstract: A tilting member has a force bearing portion to which operating force is applied, and a supported surface. A supporting member has a supporting projection with which the supported surface of the tilting member may come in contact. When the operating force is applied to the tilting member, the tilting member tilts with respect to the supporting member. The supporting member supports the tilting member at a supporting point where the supporting projection of the supporting member is in contact with the supported surface of the tilting member, about which supporting point the tilting member tilts. The tilting of the tilting member, with respect to the supporting member, establishes a predetermined electrical contact.
