  • Patent number: 7774281
    Abstract: A terminal device transmits device information thereof and a request for acquiring information contents to a contents distribution device. The contents distribution device generates a request for distributing a program for materializing the information contents in the terminal device based on the information contents designated in the acquisition request and the device information, and transmits a license request for using a function standard required for realizing the function to a license management device. The license management device receives the usage license request and correspondingly transmits an authorization for using the function standard to the program distribution device and the contents distribution device. The program distribution device transmits the program to the terminal device only when the usage authorization is received. The contents distribution device transmits the information contents to the terminal device only when the usage authorization is received.

  • Patent number: 7137770
    Abstract: A transporting apparatus is provided with a moving platform capable of moving vertically, an article loading platform that can be moved horizontally with respect to the moving platform, a contactless sensor provided on the moving platform, a detected member that is provided on the article loading platform, whose position can be altered between an position detected and a position not detected by the contactless sensor, and an operating member operatively linked to the detected member. The operating member can come into contact with an article loaded on the article loading platform, and changes the position of the detected member between the detected position and the non-detected position. Due to this configuration, it is possible to provide an article position sensor between the article loading platform and the moving platform without using wires, which are deteriorated due to the relative movement between the article loading platform and the moving platform.
