  • Patent number: 11925458
    Abstract: A motion state monitoring system, a training support system, a motion state monitoring method, and a program capable of suitably managing measurement results according to an attaching direction of a sensor are provided. A motion state monitoring system according to the present disclosure monitors a motion state of a target part of a subject's body. The motion state monitoring system includes an acquisition unit, an attaching direction detection unit, and a control processing unit. The acquisition unit acquires sensing information of a sensor attached to the target part. The attaching direction detection unit detects an attaching direction of the sensor. The control processing unit outputs information related to the sensing information in association with the attaching direction.

  • Patent number: 6694117
    Abstract: A color electrophotographic apparatus eliminates necessity of mechanism for urging the developer from the front side. The developer is placed away from a photo conductor. On both sides of the developer, mutually cooperated gears are provided. One of the gear meshes with a drive gear with a clutch for driving the developer. The other gear is meshed with a brake gear coupled with a brake mechanism whose brake function can be turned On and OFF by an electric signal. The drive gear is arranged to urge the developer onto the photo conductor by rotation thereof. When the gear of the developer rotates, the brake gear is arranged at a position to urge the developer onto the photo conductor. The torque to start slippage of the brake is set at a value to be greater than a force of a spring pushing back the developer.

  • Patent number: 6574447
    Abstract: In an electrophotographic device, a method is provided in which laser power is regulated at two predetermined points of gradation. More specifically, a first laser power regulating means which regulates the magnitude of a laser power output and a second laser power regulating means which regulates the slope of laser power gradation characteristic are provided. Thereby, stabilization of the laser power output value is realized at any stage of the gradation, and an electrophotographic device can be provided which reduces variability in image quality between electrophotographic devices.
