A contact/non-contact type hybrid IC card is provided which includes a non-contact interface to communicate in a non-contact manner with a non-contact type reader/writer through an antenna, a contact interface to communicate in a contact manner with a contact type reader/writer through a contact terminal, a storage unit to store personal identification information input from the contact type reader/writer through the contact interface during a contact communication mode by the contact interface, and a control unit to remove a limitation of a prescribed function in a non-contact communication mode by the non-contact interface based on the personal identification information stored in the storage unit during the contact communication mode and switch a communication mode from the contact communication mode to the non-contact communication mode with the limitation of the prescribed function being removed.
摘要:
An information processing system includes a first information processor to process data to be displayed in a first display unit and a second information processor to indicate the data displayed in the first display unit. The first information processor includes a first display control unit to control the data to be displayed; a first communication unit to receive operation information from the second information processor and transmit data information about a piece of data indicated by the second information processor; and a first detecting unit to detect a position on the first display unit indicated by the second information processor. The second information processor includes an accepting unit to accept an operation by a user; a second communication unit to transmit operation information to the first information processor and receive the data information from the first information processor; and a received data storage unit to store the data information.
摘要:
A WiGig wireless device partially performs a masking processing on a preamble of a transmission signal frame and generates a repetition pattern of the same pulse capable of being used in a correlation detection of a sensor. That is, a repetition pattern of a Golay code is output by intermittently performing the masking processing on the Golay code sequence. The sensor performs the correlation detection using a pulse compression technology, thereby detecting the antenna radiation pattern even in an environment where a reflected wave is generated, by separating the direct wave and the reflected wave.
