Patent number: 9706955Abstract: Provided is a biological state assessment device for assessing biological state, such as mood or emotions, using non-invasive biophotonic measurement technology. The present invention includes a light irradiation unit (1041), a light-receiving unit (1061), and an inputting means (112). A subject (800) is presented with a plurality of different problems (first problem, second problem), and a biological signal in the interior of the subject is calculated from the intensity of light received by the light-receiving unit (1061). Subjective information about the subject is accepted by the inputting means (112). The difference is calculated between the subjective information and the relative value of the biological signal of the measurement point for the first problem and the biological signal of the measurement point for the second problem, and the result is displayed.Type: GrantFiled: June 21, 2012Date of Patent: July 18, 2017Assignee: Hitachi, Ltd.Inventors: Hirokazu Atsumori, Masashi Kiguchi

Patent number: 9592000Abstract: A biosensor including light emitting elements and a light receiving element disposed on a principal surface of a wiring board; a light shielding portion disposed between a light-emitting-element sealing portion and a light-receiving-element sealing portion; a base medium having light transmitting properties, disposed in parallel with the wiring board with the light shielding portion therebetween; an adhesion layer having light transmitting properties that bonds the base medium with the light-emitting-element sealing portion, the light-receiving-element sealing portion, and the light shielding portion; and a first electrocardiograph electrode attached to a principal surface of the base medium. Both end portions of the adhesion layer and both end portions of the base medium are disposed such that they overlap neither of the light-receiving-element sealing portion nor the light-emitting-element sealing portion when viewed from a direction normal to the principal surface of the wiring board.Type: GrantFiled: February 18, 2014Date of Patent: March 14, 2017Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Toru Shimuta, Yasutaka Fujii

Patent number: 9549695Abstract: A parameter affecting the absorptivity or the concentration of blood in tissue is measured using a semiconductor light source (7) and a light detector (8). The semiconductor light source (7) is operated at several operating conditions, at which it has different temperatures and therefore different emission spectra. In particular, the operating conditions correspond to different time intervals after switching the light source (7) on, while the light source (7) has not yet reached thermal equilibrium. This allows to perform a spectroscopic measurement using one light source only, which increases accuracy and reduces device cost.Type: GrantFiled: February 26, 2010Date of Patent: January 24, 2017Assignee: BIOVOTION AGInventors: Andreas Caduff, Hans-Joachim Krebs, Mark Stuart Talary, Pavel Zakharov

Patent number: 9451920Abstract: A system for measuring of arterial and venous blood constituent concentration based first on measuring cardiac blood flow balance parameter between the right chamber of the heart and the left chamber of the heart, which includes a sensor device for measuring one of blood pressure and blood flow rate and blood constituent concentration of a patient so as to generate an arterial pulse signal. A processing unit is responsive to the arterial pulse signal for generating full arterial pulse plethysmography waveforms, arterio-venous pulse plethysmography waveforms, and balance parameters. A computational device that is responsive to plethysmography waveforms generating a plurality of state space linear transfer functions by applying system identification between plethysmography waveforms at various wavelengths representing a plurality of models of the blood constituent concentration, including oxygen, carbon dioxide, hemoglobin, and glucose, and displaying related useful information.Type: GrantFiled: July 24, 2013Date of Patent: September 27, 2016Inventor: Mohammad Khair
