  • Patent number: 7771321
    Abstract: A system for managing exercise of an animal such as a human being so that the motion of the animal is induced with an appropriate scale and rhythm in accordance with the physiological conditions of the animal is provided. According to the exercise management system (1) of the present invention, during the process where the user's walking motion is induced by an operation of a walking motion induction device (20), a walking ratio (k) and a physiological variable such as consumed energy are measured. Then, the walking ratio (k) in the state where the physiological variable attains an appropriate value in consideration of activation of physical functions or reduction of body load of the user is set as a recommended walking ratio (k0). This ensures that the recommended walking ratio (k0) is set as appropriate in consideration of activation of the physical functions of the user or the like.

  • Patent number: 7758470
    Abstract: A system for managing exercise of an animal such as a human being so that the animal can be trained to move with an appropriate scale and rhythm while harmonizing the motion of the animal with the operations of two devices which induce the motion of the animal in different manners, is provided. According to the exercise management system (1) of the present invention, the speed of the walking motion of the user is adjusted by an operation of a treadmill (first motion induction device) (10). The user's walking motion is induced with the motion scale being adjusted with a rhythm harmonized with the motion rhythm of the animal by an operation of a walking motion induction device (second motion induction device) (20). At this time, the operation of the walking motion induction device (20) is controlled based on the walking speed v (walking rate p, as required).

  • Publication number: 20100132464
    Abstract: According to a motion assisting device 10 of the present invention, “second setting processing” is exceptionally performed in a situation where it is likely that the motion mode of an agent P gets out of harmony with the operation mode of the motion assisting device 10, more specifically a situation where a deviation absolute value between a first phase difference and a desired phase difference is equal to or greater than a threshold value. Besides, only a single model may be used for arithmetic processing for generating a basic oscillator as an operation control basis of an actuator 15.

  • Publication number: 20100049102
    Abstract: Provided is a motion assisting device capable of assisting a periodical walking motion of a creature so as to conduct a smooth motion of a leg thereof. According to the motion assisting device (10) of the present invention, an assisting force applied to the creature so as to assist a leg of the creature in moving with respect to a body thereof is reinforced by an increment in an auxiliary coefficient increased in a reinforcement duration. Accordingly, the stretch motion of the leg at the on-ground state is assisted by a relatively stronger assisting force. Thereby, the body is conducted to translate forward by a floor reaction force subjected to the leg at the on-ground state. A flexion motion of the leg at an off-ground state is induced by a reflex (stretch reflex) to the stretch motion of the leg by the assisting force at a previous off-ground state.

  • Publication number: 20090270766
    Abstract: A device for inducing a user's motion in a rhythm responsive to a motion rhythm after the user's motion rhythm changes suddenly. The walking assist device generates a first oscillator which attains mutual entrainment with a user's hip joint angular velocity to reflect a natural angular velocity. On the other hand, a new natural angular velocity is set based on the phase difference between the hip joint angular velocity and the first oscillator. A second oscillator which oscillates in rhythm reflecting the natural angular velocity is generated. An inducing oscillator generated based on the second oscillator, and a torque responsive to the inducing oscillator acts on the user's body. If the magnitude of a periodic variation in the hip joint angular velocity exceeds a threshold value, a second oscillator which oscillates in rhythm reflecting the angular velocity of the first oscillator instead of the natural angular velocity is generated.

  • Publication number: 20090062884
    Abstract: A movement assist system for assisting stably a movement of a creature, particularly a creature whose body part is paralyzed due to neuropathy or the like. According to the movement assist system, walking movement of a human is assisted according to an output from an actuator of a movement assist device. A timing of an electrical stimulation applied to the creature is adjusted by an electrical stimulation device on the basis of a signal representing an arithmetic processing result by a first controller which controls the output of the actuator. According thereto, it is possible to apply an electrical stimulation to the human at an appropriate timing from the viewpoint of maintaining an appropriate posture by considering a periodical movement state of the human even in cases where the body function is degraded, allowing the human assisted by the movement assist device to continue the walking movement.

  • Publication number: 20050177080
    Abstract: A system capable of controlling an autonomous walking assist rhythm, while following changes in a walking rhythm of a walker at the same time. A control system 100 in accordance with the present invention generates a first oscillator x that tugs and is tugged by a walking oscillator (hip joint angular velocity) ?H? such that an intrinsic angular velocity is reflected. Then, a new intrinsic angular velocity ?m is determined on the basis of the difference between a first phase difference ?HM between the first oscillator x and the walking oscillator ?H? and a desired phase difference ?d. Furthermore, a second oscillator y is generated that tugs and is tugged by the walking oscillator ?H? such that the intrinsic angular velocity ?m is reflected, and has a second phase difference ?hm, which is closer to the desired phase difference ?d than the first phase difference ?HM is, with respect to the walking oscillator ?H?.
