Publication number: 20120221491Abstract: In a power interchange system, an electric power generated by a power generation device is interchanged between power consuming dwellings in a multi-family house. Each power consuming dwelling generates the power by using the power generation device and receives a commercial AC power supply via a shared power supply wiring. The amount of electric power supplied to each power consuming dwelling is managed by a power management device. The power management device manages a surplus power amount of one power consuming dwelling and a required electric power amount of another power consuming dwelling and supplies the surplus power from the former power consuming dwelling to the latter power consuming dwelling via the power supply wiring.Type: ApplicationFiled: October 28, 2010Publication date: August 30, 2012Applicant: PANASONIC CORPORATIONInventors: Hiroaki Koshin, Akira Yoshitake, Yuusuke Iwamatsu, Kei Kawaguchi, Takuma Kawasaki

Patent number: 6658495Abstract: A server transmits an open command which orders to open ports when data is transmitted to terminals. The open command is formed with a plurality of bits so as to have flags corresponding to each port of the terminals. Among a plurality of the bits, only the bits corresponding to the ports to be opened are set to be, for example, 1 and the rest is set to be, for example, 0. In each of the terminals, each of the receivers receives the open command, and judges whether the bits corresponding itself in the open command is, for example, 1 or not. When the bit is 1, the terminal opens the port.Type: GrantFiled: April 22, 1999Date of Patent: December 2, 2003Assignee: Sony CorporationInventor: Akira Yoshitake
