Publication number: 20230387685Abstract: An energy management controller (1) includes a virtual grid generating unit (110) that for each of grids, generates a virtual grid that collectively manages information including information on an energy resource and a wire, in order to carry out efficient power management, and a deal management unit (150) that based on the generated virtual grid, manages a power deal with a consumer-side supplied with power from the energy resource. The energy management controller (1) further includes an RE coloring unit (132) that classifies power by coloring to allow power deals based on RE coloring.Type: ApplicationFiled: November 27, 2020Publication date: November 30, 2023Inventors: Nao SAITO, Norihiko MORIWAKI, Hideki HAYASHI, Masato UTSUMI, Kazuya MONDEN, Yusuke SHOMURA, Toshiaki SUZUKI, Yoshikazu ISHII, Mingyu JO

Patent number: 9402223Abstract: Before software for a routing protocol in a second wireless terminal receives a routing packet between a first wireless terminal and the second wireless terminal that are both included in an ad hoc network, stability determining software determines whether or not a link between the first wireless terminal, which is the source of the routing packet, and the second wireless terminal is stable. When the link is determined to be stable, the software for the routing protocol in the second wireless terminal processes the routing packet. This allows building of a route using only a stable link between adjacent nodes.Type: GrantFiled: July 3, 2012Date of Patent: July 26, 2016Assignee: HITACHI, LTD.Inventors: Kazuya Monden, Atsushi Shimizu, Shoji Fukuzawa

Patent number: 8229668Abstract: The present invention provides a vehicle communication system by which even when the number of other vehicles around a traffic line is increased, it is possible to prevent occurrence of a situation that there are located vehicles the number of which is larger than the capacity of a communicable network, and it is possible to secure communications with the other vehicles. Even when it is determined that a host vehicle enters in a traffic line and a plurality of other vehicles the number of which is larger than a threshold value are located in front and rear virtual regions of the host vehicle, a transmission power is reduced to the extent that communications between the host vehicle and one of the other vehicles that is located furthest in the virtual regions can be secured.Type: GrantFiled: May 5, 2010Date of Patent: July 24, 2012Assignee: Renesas Electronics CorporationInventors: Takashi Kawauchi, Takahiro Fujishiro, Yuki Horita, Kazuya Monden

Patent number: 8121066Abstract: One objective of the present invention is to determine a location for a relay terminal in a radio network, without preparatory surveying a radio status, and to arrange the relay terminal at the location. Another objective is to provide a method for retrieving the arranged relay terminal. When a relay terminal is to be arranged, the relay terminal transmits a survey packet to examine the quality of communication with a communication terminal or other relay terminal. Where a location is appropriate, the relay terminal gives a notice. The arranged terminal relays communication. Further, when the relay terminal is to be retrieved, the relay terminal carried by a user transmits a retrieval packet to the arranged relay terminal, which notifies the user of its presence by light, sounds, or returning a packet. In this manner, a single relay terminal provides functions of arrangement, relay and retrieval.Type: GrantFiled: October 14, 2008Date of Patent: February 21, 2012Assignee: Hitachi, Ltd.Inventors: Kazuya Monden, Tomoichi Ebata, Susumu Matsui, Tatsuaki Osafune
