Publication number: 20230148929Abstract: A wearable device includes a biomedical electrode that can be placed on the target living subject for measurement and that detects the bioelectric potential according to the electric current coming from the target living subject for measurement; and a detection circuit that detects biological signals from the detected bioelectric potential. The biomedical electrode includes an elastic body that has a frame member having an opening and nonconductive; and includes a conductive fiber that is placed on the surface of the elastic body and that detects the bioelectric potential according to the electric current coming from the target living subject for measurement.Type: ApplicationFiled: November 15, 2022Publication date: May 18, 2023Applicant: HappyJapan Inc.Inventors: Kenichi Mori, Masayoshi Yokoo, Kenji Seino

Patent number: 7861115Abstract: To reset only the CPU in a component in an abnormal condition without affecting CPUs of components in a normal condition, a multi-component system, in which a plurality of components each including at least a CPU are connected via a common bus to each other, includes a first reset signal generating unit which generates a reset signal by a switch operation to send the reset signal to respective components and a judge unit which is disposed in each component to determine whether or not resetting of a CPU is allowed. The judge unit inhibits, if the CPU is in a normal condition, the resetting of the CPU in response to the reset signal and resets, if the CPU is in an abnormal condition, the CPU in response to the reset signal.Type: GrantFiled: June 24, 2008Date of Patent: December 28, 2010Assignee: Hitachi Industrial Equipment Systems Co., Ltd.Inventors: Norihisa Yanagihara, Hajime Kihara, Tsutomu Yamada, Makiko Naemura, Kenji Seino

Patent number: 6413090Abstract: A simulation rider transporting apparatus includes a seat having means for constraining an attitude of a rider mounted on a first base and having a second base positioned under the first base. Elevation means for elevating the first base include two cranks which are arranged opposite to each other between the first and the second base. Each of the cranks has crank arms with each crank arm having one end coupled to the second base. A crank rod is provided for coupling the other end of each crank arm to the first base. Drive means are provided for changing a relative angle between the two crank arms to a predetermined value and for holding the changed relative angle.Type: GrantFiled: March 26, 1999Date of Patent: July 2, 2002Assignees: Hitachi, Ltd., Hitachi Keiyo Engineering Co., Ltd.Inventors: Tsukasa Shiina, Minoru Katoh, Masayuki Oshiro, Takayuki Kamiya, Hiroshi Sakairi, Masami Otomo, Kenji Seino
