  • Patent number: 11406871
    Abstract: An ergometer according to this invention comprises pedals rotated by an exerciser, a motor connected to the pedals, and a control device connected to the motor in order to control an operation of the motor, wherein a control mode of the control device for controlling the motor can be switched between a concentric contraction exercise mode, in which the motor is caused to function as a load while the pedals are rotated by the exerciser, and an eccentric contraction exercise mode, in which the motor rotates the pedals so that the exerciser is forced to resist the rotation of the pedals.

  • Patent number: 11324404
    Abstract: A kinesitherapy apparatus includes a measuring instrument, a pedaled rotational mechanism, a rotating electrical machine configured to apply an assist load, which is a regenerative load or a power running load, to the pedaled rotational mechanism, and a motion control device. The motion control device performs power running operation of the rotating electrical machine so that a minus assist load is generated in a warm-up period. In a ramp loading period following the warm-up period, the motion control device raises the assist load from the minus assist load, and calculates an anaerobic threshold based on time-series data of oxygen uptake and carbon dioxide emission that are obtained via the measuring instrument.

  • Patent number: 10112077
    Abstract: An electric training apparatus is configured to apply, by a load motor, a load on a rotating body configured to apply a load on an exercising person, detect an exercise physiological response value of the exercising person and a number of revolutions of the rotating body, perform control for gradually increasing the load of the load motor toward a set load upper limit value so that a detection result of the exercise physiological response value of the exercising person approaches a target exercise physiological response value set in advance, and change, before an exercise or during the exercise by the exercising person, the load upper limit value in response to a control command input based on a state of the exercising person, a state of the control, and a perceived exertion scale for the exercising person.

  • Patent number: 6317151
    Abstract: At each of n shooting (or capturing) points, a natural scene is captured for a period of time tS(N), where N=1 to n, using one or more video cameras held at rest, and it is then converted into each of a plurality of stationary-viewpoint images. Furthermore, on the way from the (N−1)th shooting point to the Nth (N=2 to n) shooting point, a natural scene is captured for a period of time tM(N), where N=2 to n, using the video cameras being moved and it is then converted into each of a plurality of moving-viewpoint images. In order to provide a virtual reality environment for a user, the plurality of stationary-viewpoint images and the plurality of moving-viewpoint images are reproduced in turn according to user's movements detected.
