Inventive embodiments are directed to components, subassemblies, systems, andor methods for continuously variable transmissions. The wheelchair is artistically decorated in one or more ways so as to have a more pleasant appearance. The local mode operates as an active node, or a standby mode, and the local mode operates as a standby node. An interrupt signal control section causes a running OS to perform the interrupt processing to change the interrupt priority in the interrupt number priority conversion table when the converted interrupt priority matches an interrupt priority related to the running OS, and stops the running OS and starts the other OS when the interrupt priorities do not match. The center of mass and the geometric centre are coincident. Thus, in the event that a plurality of persons are access to a single document, access rights are suitably applied to the plurality of persons.
