  • Publication number: 20220183578
    Abstract: Provided is a technology of allowing evaluation of a vascular endothelial function stably and accurately at relatively low introduction cost, regardless of an examiner's skill. Using a pressure applying belt including an inflatable bladder, which is similar to a cuff for blood pressure measurement, the vascular endothelial function is evaluated. As pre-processing, while an arm tightening force by the pressure applying belt is changed, a maximum pulse wave pressure being a an air pressure inside the inflatable bladder at the time when a pulse wave amplitude is maximum is identified, and the pulse wave amplitude at this time is recorded. Next, occlusion processing of causing occlusion in the arm and releasing the occlusion is performed. Then, as post-processing, the pulse wave amplitude is measured while the air pressure inside the inflatable bladder is kept at the maximum pulse wave pressure, and the pulse wave amplitude at the time of its peak is recorded.

  • Patent number: 10828227
    Abstract: A method of determining a more suitable appropriate pressure for use in muscle strength enhancement methods involving the restriction of blood flow. The pressure of air in a gas bladder of a compression band is temporarily increased to a pressure higher than a presumed appropriate pressure and then gradually reduced. During this process, a pulse wave amplitude is measured, and a maximum pulse wave pressure, which is the pressure of the air in the gas bladder at a time when the pulse wave amplitude that is temporarily increased and then reduced has its maximum value is specified by a maximum pulse wave pressure specifying unit 12E. The unit 12E sends maximum pulse wave pressure data representing a maximum pulse wave pressure to an appropriate pressure calculating unit 12F. The unit 12F multiplies the maximum pulse wave pressure by a coefficient to obtain an appropriate pressure.

  • Patent number: 5808433
    Abstract: A method for generating a gait of a two-legged walking robot having a body, two articulated legs each connected to the body through a hip joint and each including a thigh link, a crus link connected to the thigh link through a knee joint and a foot connected to the crus link through an ankle joint, the robot being configured to drive the articulated legs as a foreleg and a hind leg such that the hind leg kicks ground to walk in a direction. In the method, a position of the robot body at a time when the hind leg has kicked the ground is estimated, and an amount of lift, in the direction of gravity, of a heel of the foot of the hind leg is determined such that the robot body will reach at least the estimated position. Then a vertical amplitude of the robot body trajectory is temporarily determined and is then corrected such that the vertical acceleration becomes a desired value, and the gait is then determined or generated based thereon. The robot locomotion is then controlled based on the generated gait.

  • Patent number: 4470124
    Abstract: A method of zero-level adjustment of a rate sensor wherein the zero-level adjustment in the detection of yawing rate is obtained by subtracting a quantity of drift of an output from the rate sensor during the period of time that the vehicle is stopped or standing still from a subsequent output therefrom in the normal travelling operation of the vehicle. The current state of the vehicle, i.e., whether it is travelling or standing still, is detected by a travel distance sensing device which generates electric pulse signals for a given unit distance travelled by the vehicle; and the sampled outputs from the rate sensor are averaged for the period from immediately after the detection of a standing still state of the vehicle to the moment just before a starting of travel thereof. The thus-obtained averaged value is determined as a current drifting value of the sensor and is subtracted from a current angle of deviation value obtained during normal travel of the vehicle.
