Abstract: This key information generation system generates key information necessary when using a shared device and imparts this key information to a mobile terminal. Authentication is performed between a mobile terminal which has imported key information, and an authentication device provided to the device, and if said authentication is successful, the mobile terminal enables operation of the device via the authentication device. The key information generation system includes: an information management unit which manages, by associating with one another, individual information for the authentication device, a key information generating code, and usage information pertaining to the use of the authentication device; and a key information generation unit which specifies a key information generation code from the individual information and usage information managed by being associated with one another by the information management unit, and generates key information on the basis of the key information generation code.

Abstract: A sharing system includes an authentication device arranged in an operation subject. The sharing system includes mobile terminals that obtain code information required to use the operation subject. The mobile terminals are allowed by the authentication device to operate the operation subject if authenticated through communication with the authentication device. The sharing system further includes a terminal checking unit that checks how many of the mobile terminals located near the authentication device can connect to the authentication device in a manner allowing for communication and can operate the operation subject. The sharing system further includes a connection switching unit that switches a connection mode of the mobile terminals that are connected to the authentication device in a manner allowing for communication based on a checking result of the terminal checking unit.

Abstract: A sharing system includes an authentication device arranged in an operation subject that can be entered and exited. The sharing system includes mobile terminals that obtain code information required to use the operation subject. The mobile terminals are allowed by the authentication device to operate the operation subject if authenticated through communication with the authentication device. The sharing system further includes a terminal checking unit that checks the number of the mobile terminals that are located near the authentication device and can communicate with the authentication device. The sharing system further includes a process execution unit that executes a process, in a case where the number of the mobile terminals checked by the terminal checking unit is more than one and any one of the mobile terminals is left forgotten in the operation subject, for allowing another one of the mobile terminals to operate the operation subject.

Abstract: A sharing system includes a sharing device arranged in a shared subject. The sharing system further includes portable terminals including a main terminal and a further terminal, each obtaining key information required to use the shared subject and configured to operate the shared subject when authenticated through communication with the sharing device. The sharing system further includes a connection control unit configured to switch communication connection between the main terminal and the sharing device to manual connection when operation privilege is granted from the main terminal to the further terminal.

Abstract: A valet key control system includes a time monitoring unit and a communication subject setting unit. The time monitoring unit is configured to monitor a remaining time of a reserved period during which the valet key is allowed to be used as the vehicle key. The communication subject setting unit is configured to set a communication subject of the valet key in accordance with the remaining time of the reserved period.

Abstract: A valet key operable as a vehicle key when lending a vehicle to a third person includes a state determination unit configured to determine whether or not the valet key is operable as the vehicle key when the valet key transmits a radio wave. The valet key further includes a communication subject setting unit configured to set a communication subject to which the valet key transmits the radio wave based on the determination result of the state determination unit.

Abstract: A rotary dial assembly includes a rotary dial configured to selectively display a plurality of graphical images and a polarized film assembly disposed in the rotary dial and configured to control the selective displaying of the plurality of graphical images on the rotary dial. When the rotary dial is rotated the polarized film assembly is illuminated such that at least one of the plurality of graphical images is displayed on the rotary dial assembly.

Abstract: A valet key that is usable as a vehicle key when lending a vehicle to a third person includes an operation error monitoring unit and a notification unit. The operation error monitoring unit is configured to monitor whether or not an operation error has occurred in a user operation performed to actuate the vehicle. The notification unit is configured to have an output device issue a notification corresponding to the operation error, when the operation error monitoring unit determines that the operation error has occurred, by transmitting the operation error to the output device through a communication protocol allowing for communication with numerous unspecified communication peers.
