Abstract: A motor control system includes a control unit and a compensator. The control unit controls an operation of a shaft of a motor in accordance with an operation command for the motor. The compensator calculates compensation information based on an other-shaft information about an operation of another shaft of another motor different from the motor. The compensation information is information for compensating an influence of the operation of the other shaft upon the shaft. The control unit controls the operation of the shaft using the compensation information calculated by the compensator.

Abstract: An assistance apparatus includes wires, each of which couples an upper-body belt and one of left and right knee belts to each other, and a motor. To promote implementation of first assistance for a user in walking while carrying an object, the motor generates a tension greater than or equal to a third threshold value in a second wire and a fourth wire, a tension greater than or equal to the third threshold value in the second wire and a third wire, and a tension greater than or equal to the third threshold value in a first wire and the fourth wire. During execution of the operation described above, upon receipt of determination of implementation, to indicate that implementation of the first assistance is determined, the motor generates a tension greater than or equal to a fourth threshold value in the second wire and the fourth wire, a tension greater than or equal to the fourth threshold value in the second wire and the third wire, and a tension greater than or equal to the fourth threshold value in the first wire and the fourth wire.

Abstract: An assistance apparatus includes first to eighth wires that couple an upper body belt to be worn on an upper body of a user to a first knee belt and a second knee belt to be worn above a left knee and a right knee of the user, respectively, and a motor. In a case of assisting the user in turning left, the motor generates, when a right leg of the user is in a stance phase, a tension larger than or equal to a first threshold in each of the second, fourth, sixth, and eighth wires at an identical timing. In a case of assisting the user in turning right, the motor generates, when a left leg of the user is in a stance phase, a tension larger than or equal to the first threshold in each of the first, third, fifth, and seventh wires at an identical timing.

Abstract: A blood pressure measurement device includes an annular bracelet that comes into contact with the user's wrist; a display that is disposed on the outer surface of the bracelet and includes a display surface; a camera that is disposed on the outer surface of the bracelet, has an optical axis tilted from the direction of a normal to the display surface, and captures images of the user; a pulse wave sensor that is disposed on an inner surface of the bracelet and detects a pulse wave at the user's wrist; and a processing circuit that estimates the user's blood pressure. The processing circuit calculates a first pulse wave timing from a temporal change in luminance in the cheek region in the images, determines a second pulse wave timing from the detected pulse wave, and estimates the blood pressure from a time difference between the first and second pulse wave timings.

Abstract: There is provided an assistance apparatus in which when assistance provided to a user in walking is to be stopped, a motor reduces a tension of a first wire and a tension of a second wire, which couple an upper-body belt and a left knee belt to each other on or above a front part and a back part of a body of the user, to less than a second threshold value during a first stop period in a gait phase of a left leg of the user, the first stop period being a period from a period included in a first period and including a timing at which the left leg shifts from a stance phase to a swing phase to a start period of a second period, and reduces a tension of a third wire and a tension of a fourth wire, which couple the upper-body belt and a right knee belt to each other on or above the front part and back part of the body of the user, to less than the second threshold value during a second stop period in a gait phase of a right leg of the user, the second stop period being a period from a period included in a third period and including a timing at which the right leg shifts from the stance phase to the swing phase to a start period of a fourth period.

Abstract: An assistance apparatus includes wires that couple an upper body belt to be worn on an upper body of a user to first and second knee belts to be worn above left and right knees of the user, and a motor. In a case of assisting the user in turning left, the motor generates a tension in second and fourth wires in a period of 65% or more and 100% or less of a first gait phase of a left leg and a period of 0% or more and 20% or less of a second gait phase of the left leg, and generates a tension in sixth and eighth wires in a period of 65% or more and 100% or less of a first gait phase of a right leg and a period of 0% or more and 20% or less of a second gait phase of the right leg.

Abstract: An assistance apparatus includes a first wire and a second wire that couple an upper-body belt and a left knee belt to each other on or above a front part and back part of the body of a user, respectively, a third wire and a fourth wire that couple the upper-body belt and a right knee belt to each other on or above the front part and back part of the body of the user, respectively, and a motor. When assistance is stopped, the motor reduces the tension of the first wire during a first stop period starting in a boundary period in a first period and ending in a start period of a second period, generates no tension in the second wire during the second period, reduces the tension of the third wire during a second stop period starting in a boundary period in a third period and ending in a start period of a fourth period, and generates no tension in the fourth wire during the fourth period. The boundary period includes a timing at which each leg of the user shifts from a stance phase to a swing phase.

Abstract: An assistance apparatus includes wires, each of which couples an upper-body belt and one of left and right knee belts to each other, and a motor. When the assistance apparatus assists a user in walking backward while carrying an object, the motor generates, in a gait phase of a left leg, a tension greater than or equal to a second threshold value in a second wire during a fifth period other than a first period during which a tension greater than or equal to a first threshold value is generated, and a tension less than the second threshold value in a first wire during a sixth period other than a second period during which a tension greater than or equal to the first threshold value is generated, and generates, in a gait phase of a right leg, a tension greater than or equal to the second threshold value in a fourth wire during a seventh period other than a third period during which a tension greater than or equal to the first threshold value is generated, and a tension less than the second threshold value in a third wire during an eighth period other than a fourth period during which a tension greater than or equal to the first threshold value is generated.

Abstract: An assistance apparatus includes a first wire and a second wire that couple an upper-body belt and a left knee belt to each other on or above a front part and back part of the body of a user, respectively, a third wire and a fourth wire that couple the upper-body belt and a right knee belt to each other on or above the front part and back part of the body of the user, respectively, a motor, a left sensor on the left hand of the user, and a right sensor on the right hand of the user. When a left sensor value of the left sensor is larger than a right sensor value of the right sensor, the tension of the first wire and the second wire is made greater than the tension of the third wire and the fourth wire. When the right sensor value is larger than the left sensor value, the tension of the third wire and the fourth wire is made greater than the tension of the first wire and the second wire.
