  • Publication number: 20240089259
    Abstract: In a remote authorization control system including a resource access device, a resource management device, and an authentication device, the resource access device downloads an access control list from the authentication device onto a secure region in the resource access device. The resource access device downloads resources from the resource management device onto the secure region. The resource access device determines whether a user is allowed to use the resources based on the access control list when a resource use request is received from the user, and the resources access device allows the user to use the resources when the resources are usable.

  • Publication number: 20240017673
    Abstract: The virtual image display device comprises a surrounding state recognizer that acquires a travel direction distance and a lateral direction distance to an object, and a display controller that displays object icon images I1, I2 in a screen 51. The display controller is capable of switching between displaying an image in a normal mode, in which the display positions of the images I1, I2 move closer in a lateral direction to a lateral reference line L1 as the travel direction distance increases, and move farther away in a screen vertical direction from a screen bottom line L2 as the travel direction distance increases, and displaying the image in a magnification mode, in which a vertical scale, which is the ratio of the distance between the line L2 and the display positions in the screen vertical direction to the orientation direction distance, is larger than in the normal display mode.

  • Publication number: 20160082635
    Abstract: A lower mold and an upper mold are combined to form an enclosed space containing a production cavity and a sealed room. A base fiber material is placed in the production cavity. The production cavity has a first space and a second space. After a gas in the enclosed space has been discharged, a first predetermined amount of a liquid resin is supplied to the first space. After supply of the liquid resin is stopped (or while the liquid resin is continuously supplied), the upper mold is lowered relatively further toward the lower mold, whereby the volume of the production cavity becomes reduced. Preferably, a second predetermined amount of the liquid resin is supplied to the first space having a large volume, whereupon the supplied liquid resin flows from the first space into the second space having a small volume.

  • Publication number: 20130160032
    Abstract: A driver controlling device is disclosed. A UI module stores information of supportable functions of drivers in a function table, and obtains information of functions of a model of a new driver to be used described in model dependent data of the new driver. The UI module determines whether the obtained information of the functions of the new driver has been stored in the information of the supportable functions. When the obtained information of the functions of the new driver has not been stored in the information of the supportable functions, the UI module stores the information of the functions of the new driver which has not been stored in the information of the supportable functions in a un-supporting function list and prevents the new driver from using the information of the functions in the un-supporting function list.
