  • Publication number: 20210248738
    Abstract: An identification apparatus includes a processor and a memory configured to store a program to be executed by the processor. The processor acquires first image data obtained by capturing of an image of an affected area included in a skin or a mucosa by receiving first reception light. The first reception light is reflection light reflected from the affected area irradiated with first irradiation light including white light. The processor further acquires second image data obtained by capturing of an image of the affected area by receiving second reception light. The second reception light is light including light generated by fluorescent reaction in the affected area irradiated with second irradiation light. The second irradiation light includes light that allows the affected area to show fluorescent reaction when the affected area is irradiated with the light. The processor identifies the affected area based on the first image data and the second image data.

  • Patent number: 10694980
    Abstract: An exercise support device and an exercise support method are provided by which a judgment regarding the landing of the left and right feet of a user can be accurately made with low power consumption, so that the user can appropriately grasp and judge the balance of the use of the body in an exercise. First, based on changes in acceleration in a vertical direction with respect to the ground which has been acquired by a sensor section worn on the body during a running exercise, landing timing at which one of the left and right feet is landed is detected. Then, based on whether a difference between angular velocities around a traveling direction axis immediately after the latest landing timing and the preceding landing timing has a positive or negative value, whether the landed foot is the left foot or the right foot is judged.

  • Patent number: 10108199
    Abstract: A determination on whether or not a local device position and a map contain an error is made. A position measurer of an autonomous movement device measures a local device position. A map memory stores the created map. A position estimator estimates the local device position. A determiner determines whether or not a difference between the measured position by the position measurer and the estimated position by the position estimator is within a predetermined error range. A map editor edits the stored map in the map memory when the determiner determines that the difference is out of the predetermined range.
