  • Publication number: 20170096993
    Abstract: A tube pump and a fluid delivery method, the tube pump including a plurality of pressing portions and a tube that delivers fluid. The pressing portions is spaced apart from each other in a rotational direction and provided for a rotation body turned by a drive unit and the tube is provided on an outer circumferential side of the rotation body. The tube pump includes a control unit that turns the rotation body opposite to a delivery direction until the rotation body reaches a predetermined angle so as to restore an area of the tube, pressed by the pressing portion on a most upstream side in the delivery direction, by an increase in pressure within the tube accompanied with a movement opposite to the delivery direction of the pressing portion adjacent to a downstream side in the delivery direction.

  • Publication number: 20170049398
    Abstract: To allow an implantable device including an electronic circuit to be implanted in the head in a more preferable manner in terms of appearance and safely. This implantable device is used for a brain-machine interface or the like. A casing of an implantable device configured to be implanted in a human head has an outer convexity surface matching an external shape of a resected skull related to at least a craniotomy site of the artificial bone designed in accordance with a skull shape of each person in order to fill the craniotomy site. That is, the outer convexity surface of the artificial bone is provided with two functions: the original function of filling the craniotomy site as the artificial bone and a function of serving as the casing of the implantable device.

  • Patent number: 8396546
    Abstract: A machine control device includes: first decoders for estimating, from brain signal information, which one of body movements a user performs or images, based on learning using pairs of movements performed by the user and brain signal information, the body movements going toward one of first to nth body postures; second decoders for estimating from the brain signal information, an correct rate on the body movement estimation, based on learning using pairs of correct rates of the estimation of body movements and the brain signal information; and electric prosthetic arm control section for controlling an electric prosthetic arm to change stepwise its posture between first to nth postures via at least one intermediate posture therebetween, the first to nth postures corresponding to the first to nth body postures. The first decoders perform the estimation only when the estimated correct rate exceeds a threshold.
