Abstract: An electronic device includes a storage that stores therein pulse rate ranges using a resting heart rate of a user as a reference to be associated with exercise amounts, respectively, and a processor. The processor executes a process including: acquiring a first sensor value and a second sensor value from a first sensor and a second sensor that are sensors worn on a body of the user, respectively, the first sensor detecting pulses and the second sensor detecting an acceleration; calculating a plurality of pulse rate candidates based on the acquired first sensor value; calculating an exercise amount of the user based on the acquired second sensor value; and specifying a pulse rate range stored in the storage to be associated with the calculated exercise amount and deciding a pulse rate candidate included in the specified pulse rate range as a pulse rate of the user.

Abstract: A microscopic object collecting method collects a plurality of microscopic objects dispersed in a sample. The method includes: irradiating a thin film with a plurality of laser beams, the thin film being provided on a bottom surface of an collection container containing the sample, the plurality of laser beams being separated from each other; and heating the sample with the plurality of laser beams to generate a plurality of microbubbles corresponding to the plurality of laser beams and to generate heat convection in the sample. An interval between adjacent two laser beams of the plurality of laser beams is narrower than a distance that allows three larger microbubbles to be virtually arranged in a gap between two microbubbles corresponding to the two laser beams, each of the three larger microbubbles being the larger one of the two microbubbles.

Abstract: An optical sensor includes a substrate, a light emitting element, a light receiving element, and an electrical component. The light emitting element is mounted on a front surface of the substrate. The light receiving element is mounted on the front surface of the substrate and at a position different from that of the light emitting element. The electrical component is mounted on a back surface of the substrate. The electrical component is electrically connected to the light emitting element and the light receiving element. The electrical component is located at a position overlapping the light emitting element and the light receiving element in plan view.

Abstract: A microscopic object detection system includes a collecting kit and a detection device. The collecting kit has a thin film for converting light into heat and is configured to be capable of holding a sample on the thin film. The detection device detects a plurality of microscopic objects in the sample by collecting the plurality of microscopic objects dispersed in the sample with the collecting kit. The detection device includes a laser module, an optical receiver, and a controller. The laser module emits a laser beam with which the collecting kit is irradiated. The optical receiver detects the laser beam from the sample held by the collecting kit and outputs a detection signal thereof. The controller calculates an amount of the plurality of microscopic objects collected in the sample based on a change of the detection signal over time.

Abstract: A method of collecting resin beads includes first to fourth steps. The first step is a step of preparing a sample on a thin film provided on an upper surface of a substrate. The second step is a step of irradiating the thin film with a laser beam and a laser beam with the laser beam and the laser beam being distant from each other. The third step is a step of producing a microbubble at a position irradiated with the laser beam and producing a microbubble at a position irradiated with the laser beam, by heating the sample by irradiation with the laser beams. The fourth step is a step of collecting a plurality of resin beads in a region between the microbubble and the microbubble by producing convection of the sample in a direction perpendicular to a direction of alignment of the microbubble and the microbubble.

Abstract: A laser module includes a plurality of light emission regions and the plurality of light emission regions emit a plurality of laser beams. An optical waveguide and a lens condense the plurality of laser beams to an identical focal point. An adjustment mechanism is configured to adjust relative positional relation between the sample stage and a condenser lens (the optical waveguide and the lens). A controller is configured to switch between a single-point irradiation mode and a multi-point irradiation mode. The single-point irradiation mode refers to a mode in which the adjustment mechanism is controlled such that the focal point of the plurality of laser beams falls on the thin film. The multi-point irradiation mode refers to a mode in which the adjustment mechanism is controlled such that the focal point does not fall on the thin film.
