Patent number: 9831923Abstract: A communication system and communication method enable various types of near field communication. NFC communication apparatuses have two features in that each can perform communication in two communication modes and that each can perform data transmission at a plurality of transfer rates. The two communication modes consist of a passive mode and an active mode. In the passive mode, between the NFC communication apparatuses, for example, a first NFC communication apparatus transmits data to a second NFC communication apparatus by modulating electromagnetic waves generated by itself, while the second NFC communication apparatus transmits data to the first NFC communication apparatus by performing load modulation on the electromagnetic waves generated by the first NFC communication apparatus. Alternatively, in the active mode, either of the NFC communication apparatuses transmits data by modulating electromagnetic waves generated by itself.Type: GrantFiled: October 19, 2016Date of Patent: November 28, 2017Assignee: SONY CORPORATIONInventors: Yoshihisa Takayama, Susumu Kusakabe, Kazushige Tsurumi, Tadashi Morita, Kunihide Fujii

Patent number: 9654319Abstract: Provided is a non-contact communication apparatus which uses a conventional IC chip without any change, while eliminating the need to transmit power to the IC chip and allowing an increase in communication range. A non-contact communication apparatus connectable to an IC chip includes an antenna section, a first detection section that retrieves a first detection signal from a signal received by the antenna section, an amplitude modulating section that amplitude-modulates a clock signal using the first detection signal retrieved by the first detection section and that inputs the amplitude-modulated signal to the IC chip, a second detection section that retrieves a second detection signal from an output signal from the IC chip, a load modulating section that load-modulates a carrier retrieved from the antenna section using the second detection signal retrieved by the second detection section and that inputs the load-modulated carrier to the antenna section, and a power supply section.Type: GrantFiled: June 13, 2013Date of Patent: May 16, 2017Assignee: QUADRAC CO., LTD.Inventors: Susumu Kusakabe, Fumio Kubono, Masanobu Sato, Keiichi Nanbu
