Patent number: 11497444Abstract: Provided is a biological information measuring instrument which can be easily and reliably worn on an appropriate position of an arm by a user. The biological information measuring instrument includes: a belt portion that is worn on a user's arm in a circumferential direction of the arm and disposed with a sensor for detecting a displacement of an arm muscle; and a case portion that is attached to a predetermined portion of the belt portion and houses a circuit component that processes a signal of the displacement detected by the sensor. The case portion has a shape of protruding from the belt portion in a longitudinal direction of the arm when the belt portion is worn on the arm, and amounts D1 and D2 of protrusions protruding in the longitudinal direction are different between one protrusion and the other protrusion.Type: GrantFiled: June 27, 2018Date of Patent: November 15, 2022Assignee: H2L Inc.Inventors: Emi Tamaki, Kenichiro Iwasaki

Patent number: 11389651Abstract: Provided are an electrical stimulation device configured so that a correspondence among finger motion and electrodes can be clarified in a short amount of time regardless of the state of attachment to a user's arm and an individual difference and an intended finger can be driven at high accuracy with very few erroneous operation and an electrical stimulation system using the electrical stimulation device. When an electrode probability matrix in which a Bayesian posterior probability indicating an electrode-finger correspondence is described as an element is updated in a host, the position of an element positioned on the upper left side of the electrode probability matrix and indicating that finger motion occurs is compared to rearrange the columns of the electrode probability matrix as necessary.Type: GrantFiled: November 12, 2019Date of Patent: July 19, 2022Assignee: H2L Inc.Inventors: Emi Tamaki, Kenichiro Iwasaki

Patent number: 10653882Abstract: Provided is an electrical stimulus device including a member to be wound around an arm of a user, multiple electrodes arranged on one surface of the member, and multiple optical distance sensors arranged on the one surface of the member. An electrical stimulus signal output from an electrical stimulus generation circuit is provided to the user from a specific electrode of the multiple electrodes to provide a stimulus to a muscle of the arm at a position facing the specific electrode, and the multiple optical distance sensors detect displacement of muscles of the arm. Some electrodes of the multiple electrodes are substantially rectangular electrodes inclined with respect to a circumferential direction of the arm of the user at a predetermined angle of lower than 90°.Type: GrantFiled: January 27, 2017Date of Patent: May 19, 2020Assignee: H2L Inc.Inventors: Emi Tamaki, Kenichiro Iwasaki
