Wireless Communication System And Wireless Terminal Apparatus For Sensor Network

View page
US Patent:
20080143512, Jun 19, 2008
Filed:
Dec 10, 2007
Appl. No.:
12/000136
Inventors:
Yoshihiro WAKISAKA - Kokubunji, JP
Norio OHKUBO - Tokyo, JP
Norihiko MORIWAKI - Hachioji, JP
Miki HAYAKAWA - Cambridge MA, US
International Classification:
G08B 23/00
US Classification:
340504, 340 102, 34028601
Abstract:
A wireless terminal comprising a radio transceiver for communicating with a base station, an infrared transceiver for communicating with another wireless terminal, a congestion control unit for detecting whether radio communication with the base station is in a collision-free state, and a communication control unit for performing radio communication with the base station by the radio transceiver after detecting unoccupied state in the radio channel by the congestion control unit and transmitting identification information to another wireless terminal by the infrared transceiver when the radio communication with the base station is completed.

US Patent:
20080297373, Dec 4, 2008
Filed:
May 22, 2008
Appl. No.:
12/153689
Inventors:
Miki Hayakawa - Cambridge MA, US
Norihiko Moriwaki - Hino, JP
Kazuo Yano - Hino, JP
Satomi Tsuji - Kokubunji, JP
Norio Ohkubo - Tokyo, JP
International Classification:
G08C 19/16
US Classification:
34087039
Abstract:
There is disclosed a sensor node capable of transmitting and receiving a large amount of data or data desired to be reliable without missing data, while preventing battery exhaustion and unnecessary compression of the transmission bandwidth. A name-tag type sensor node includes a detector for detecting connection of an external power supply. When the detector detects that the external power is supplied, the name-tag type sensor node transmits and receives a large amount of data, such as bulk transmission data, at an increased frequency by means of a data selector, a communication timing controller, and a wireless communication controller. Alternatively, the name-tag type sensor node transmits and receives the data desired to be reliable, such as rewriting data of firmware.
