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: 8224243Abstract: A communication system performs, by first and second data processing apparatuses, an electromagnetic-induction communication using a carrier having a single frequency. A transfer rate for use between the first and second data processing apparatuses is changeable in one transaction. The first data processing apparatus determines whether a transfer rate can be changed based on data transmitted from the second data processing apparatus. When the first data processing apparatus determines that the transfer rate can be changed, the first data processing apparatus transmits to the second data processing apparatus a request to change the transfer rate to one of a plurality of transfer rates.Type: GrantFiled: December 12, 2007Date of Patent: July 17, 2012Assignee: Sony CorporationInventors: Yoshihisa Takayama, Susumu Kusakabe, Kazushige Tsurumi, Tadashi Morita, Kunihide Fujii

Patent number: 6973302Abstract: The present invention relates to an information processing terminal that makes it possible to readily upgrade software of information processing terminals connected by a network. When a control program stored in a display apparatus 5B is upgraded by a control program stored on a memory card 10, an upgrade program for a base station 1 and the control program for display apparatus 5A and 5C read by the display apparatus 5B are transmitted to the base station 1. The base station 1 upgrades a control program stored therein by the upgrade program received by the base station 1, and also transmits the control program for the display apparatus 5A and 5C to the display apparatus 5A and 5C. The display apparatus 5A and 5C each upgrade a control program stored therein by the upgrade program received by the display apparatus 5A and 5C, respectively.Type: GrantFiled: November 28, 2001Date of Patent: December 6, 2005Assignee: Sony CorporationInventors: Masahiro Asai, Yoshihiko Owaki, Kazushige Tsurumi

Publication number: 20020087984Abstract: In an apparatus for receiving digital television broadcast, a user may be safeguarded from misconception that the apparatus may be in disorder. When a channel for receipt is commanded in the apparatus for receiving digital television broadcast, the number of the channel is acquired at step S11. It is verified at step S12 whether or not the channel so selected has been set as being a channel for reception. If the result of check is affirmative, a picture for the channel is displayed at step S14. If otherwise, that is if the channel selected has not been set as the channel for reception, the effect that the channel cannot be viewed is displayed at step S15.Type: ApplicationFiled: November 28, 2001Publication date: July 4, 2002Inventors: Satoru Maeda, Kazushige Tsurumi, Yushi Sayama, Munehiro Yoshikawa, Ayumi Mizobuchi, Takaaki Miura, Katsuhisa Takata, Yusuke Fujimaki

Patent number: 5404459Abstract: A serial communication port structure for starting and stopping an internal clock. This internal clock is designed, in operation, to generate a clock output signal to be transmitted to a device external to the system in which the serial communication port is incorporated. By ANDing the clock output signal with a data output signal of predetermined length, the serial communication port can effectively control the passage of time as sensed by the external device.Type: GrantFiled: July 21, 1992Date of Patent: April 4, 1995Assignees: Advanced Micro Devices, Sony CorporationInventors: Dale E. Gulick, Alan F. Hendrickson, Munehiro Yoshikawa, Hiroshi Matsubara, Kazushige Tsurumi
