  • Patent number: 6021229
    Abstract: An image processing apparatus and the method for mapping a plurality of images which are on the two-dimensional plane on the corresponding faces of a solid in the three-dimensional virtual space. The mapping image on the side face being close to the object image displaying face is formed in accordance with the shape of object image displaying face of the solid on which the object image is mapped, and the image mapped on each face is displaced in accordance with the movement of the solid in the three-dimensional space. Therefore, the image that as if a desired image is stuck to the faces of the solid moving in a virtual space can be displayed on a screen surface by easily operating by an operator.

  • Patent number: 5481140
    Abstract: The present invention relates to a power distribution control system for suppressing a total quantity of working current in a group of loads to a level equal to or lower than a set quantity of current by controlling the loads. The power distribution control system includes a central communication terminal and a plurality of customer communication terminals connected to the center communication terminal through communication lines. Each of the customer communication terminals is responsive to a presentation signal from the center communication terminal that requests time periods for, and quantities of power reduction. The central communication terminal also provides a response signal to selected customer communication terminals. The response signal indicates that a proposal for power reduction by the customer has been accepted.
