  • Publication number: 20140098959
    Abstract: An electronic key registration system includes an electronic key device that stores a key ID and a first piece of information. A controller is arranged in a communication subject. A registration tool writes the key ID to the controller and stores a second piece of information. Encrypted communication between the communication subject and the electronic key device is enabled after the key ID and a corresponding encryption key are written to the controller. An information center, which communicates with the registration tool, receives and compares the first and second pieces of information. The registration tool is permitted to write the key ID when receiving a signal from the information center indicating that the first and second pieces of information conform to each other.

  • Publication number: 20140098958
    Abstract: An electronic key registration system includes an electronic key device having a key ID. A controller having a first piece of information is arranged in a communication subject. A registration tool having a second piece of information is configured to write the key ID to the controller. The controller compares, before electronic key registration, the first piece of information and the second piece of information. The controller permits electronic key registration when the comparison indicates that the first piece of information and the second piece of information conform to each other and prohibits the electronic key registration when the comparison indicates that the first piece of information and the second piece of information do not conform to each other.

  • Publication number: 20140040831
    Abstract: The present technique relates to a display control device, a display control method, and a program that are capable of making inputtable gesture motions easy to notice. A display control unit causes a display unit to display a gesture motion guide in a first state. When a detecting unit for detecting gesture motions detects a predetermined gesture motion, the display control unit changes the guide corresponding to the detected gesture motion to a second state and then causes the display unit to display the guide. The technique according to this disclosure can be applied to an information processing terminal that includes a display unit, for example.

  • Publication number: 20130332736
    Abstract: An immobilizer ECU transmits a vehicle ID code and a SEED code, which is read from an electronic key, to a data center online. The data center generates an encryption key from the received SEED code and a first logic, and generates a further SEED code from the encryption key, the vehicle ID code, and a second logic. The immobilizer ECU obtains the further SEED code online from the data center, generates the encryption key from the obtained further SEED code, the vehicle ID code, and the second logic, and stores the encryption key.

  • Publication number: 20130301829
    Abstract: An electronic key registration system includes a controller of a communication subject, an initial electronic key that communicates with the communication subject and has an initial encryption key generation code, an additional electronic key that communicates with the communication subject, and an information center including an additional encryption key. The initial electronic key holds an initial encryption key generated from the initial encryption key generation code and a logic. The controller holds the logic and identification information of the communication subject. The controller acquires the initial encryption key generation code from the initial electronic key, generates an initial encryption key from the initial encryption key generation code and the logic held by the controller, and stores the initial encryption key. The information center sends the additional encryption key to the additional electronic key or the controller through a network.

  • Publication number: 20130285792
    Abstract: An electronic key registration system includes a controller arranged in a communication subject communicable with an electronic key. A registration tool is in wired or wireless connection with the communication subject. The registration tool registers the electronic key to the controller when receiving a registration permission signal. An information center is connected to a network. The registration tool includes an operator ID acquisition unit that acquires an operator ID from a key registration operator. A communication unit sends the operator ID to the information center through the network. The information center includes an operator ID verification unit that verifies the operator ID received from the registration tool. A permission information notification unit sends, when the operator ID is verified, a registration permission signal to the registration tool through the network to permit the registration tool to perform the registration process.

  • Patent number: 8532576
    Abstract: A portable device for preventing communication errors caused by disturbance such as noise. The portable device receives a first request signal from a communication controller and transmits a first response signal corresponding to the first request signal. A transmitter transmits the first response signal with a selected one of a plurality of frequencies. A transmission control unit transmits the first response signal from the transmitter with the one of the plurality of frequencies. The portable device further receives a second request signal from the communication control unit, which receives the first response signal. When the second request signal cannot be received, the portable device retransmits the first response signal from the transmitter with a frequency that differs from the one of the plurality of frequencies.

  • Publication number: 20130217217
    Abstract: According to one embodiment, a pattern forming method is disclosed. A resist pattern having a top surface is formed pattern on a substrate. A coating film having a first thickness distribution is formed on the substrate. The coating film covers the resist pattern. The coating film is thinned to expose the top surface of the resist pattern. The first thickness distribution is changed into a second thickness distribution which is more uniform than the first thickness distribution. The resist pattern is removed without removing the coating film. A pattern is formed in the substrate by processing the substrate by using the coating film as a mask.
