  • Publication number: 20230414142
    Abstract: A method for estimating an emotional state is executed by a computer and includes acquiring an amount of change of a cerebral blood flow of a user from a reference time, acquiring an amount of change of a heart rate of the user from a reference time, and outputting a signal indicating that the user is in an excited state in a case where the amount of change of the cerebral blood flow is smaller than a first threshold value and the amount of change of the heart rate is larger than a second threshold value.

  • Publication number: 20230301536
    Abstract: A biological measurement device includes a light emitting device, a sensor, and a processing circuit. The light emitting device irradiates a first region and a second region, which is located on an upper side relative to the first region, of a forehead of a subject with light. The sensor detects first scattering light generated by the light incident on the first region and second scattering light generated by the light incident on the second region and outputs detection signals according to intensities of the first and second scattering light. The processing circuit selects one of the first and second regions as a target region based on the detection signals and/or an image signal indicative of an image including a face of the subject and generates and outputs brain activity data indicative of a state of brain activity of the subject based on the detection signal in the selected target region.

  • Publication number: 20230083178
    Abstract: A measurement apparatus includes first and second light sources, a diffuser, a photodetector, and a processing circuit. The first and second light sources respectively output first emitted light and second emitted light. The mirror causes the first emitted light and the second emitted light to be concentrated and incident on one region of the diffuser. The photodetector detects first reflected light and second reflected light that emanate from a subject due to the first emitted light and the second emitted light diffused by the diffuser, respectively. The processing circuit generates and outputs information related to the subject, based on the result of detection of the first reflected light and the second reflected light by the photodetector. The distance between two light spots respectively formed on the one region by the first emitted light and the second emitted light is less than the distance between the first and second light sources.

  • Publication number: 20220400964
    Abstract: A measurement apparatus includes a light source, a sensor including light detection cells including a first light detection cell and a second light detection cell, and an electronic circuit. The circuit causes the light source to emit a light pulse, causes the first light detection cell to detect a reflected light pulse from a target in an exposure period including at least part of a period from when an intensity of the reflected light pulse starts increasing to when it starts falling and generate a first signal, causes the second light detection cell to detect the reflected light pulse in an exposure period including at least part of a trailing period from when the intensity of the reflected light pulse starts falling to when it stops falling and generate a second signal. The circuit generates, based on the first and second signals, data representing states of the target.

  • Patent number: 5000004
    Abstract: A gas trubine combustor includes a main body with a combustion portion into which mixture of fuel and air is supplied. The gas mixture is burned through a catalytic reaction at a catalyst body arranged in the main body. The gas mixture passed through the catalyst body is introduced into a gas phase combustion portion provided in the main body. Between the catalyst body and the gas phase combustion portion is arranged a dividing unit which has a plurality of branch passages. The gas mixture passed through the catalyst body is divided by the dividing unit into a plurality of gas streams flowing through the branch passages. Each of the gas streams is mixed with fuel supplied from a fuel supply tube.
