    Abstract: A stator includes conductive wires wound around teeth, and slots between adjacent teeth in a circumferential direction. The conductive wires include conductive wires of three phases corresponding to a U-phase, a V-phase, and a W-phase, and the conductive wires are delta connected. Coils, in which any one of the conductive wires is wound around the teeth, are repeatedly disposed in order of the U-phase, the V-phase, and the W-phase in the circumferential direction.

  • Patent number: 10238345
    Abstract: A biological information processing device includes an image input unit that inputs image data, a selection unit, an estimation unit, a detection unit, and an output unit. The selection unit selects image ranges of processing targets from the input image data. The estimation unit estimates pulse rates of the processing targets corresponding to the image ranges on the basis of image data of the selected image ranges of the processing targets. The detection unit performs relative comparison between the estimated pulse rates of the processing targets and thus detects a target which will possibly be abnormal or a target requiring special attention. The output unit outputs information regarding the detected target which will possibly be abnormal or the detected target requiring special attention.

  • Patent number: 10232909
    Abstract: A bicycle operating device includes a base member, a positioning ratchet, a positioning member, a release member and a release pawl. The positioning ratchet pivots about a pivot axis in first and second directions. The positioning member moves between a holding position that prevents pivoting of the positioning ratchet in the first direction, and a releasing position that releases the positioning ratchet to pivot in the first direction. The release member moves the positioning member from the holding position to the releasing position as the release member moves with respect to the base member. The release pawl is movably mounted with respect to the base member to move the release member. The release pawl includes first and second pawl parts that selectively contact the release member as the release pawl moves with respect to the base member. The first and second pawl parts are different from each other.
