Abstract: The present application relates a pump casing and a pump. The pump casing includes a cutter having an upper surface facing a leading edge portion of an impeller when the impeller is housed in the pump casing. The upper surface has a region with at least two angles.

Abstract: A biometric information processing device (1) includes a brain wave detecting unit (10), a control unit (20), and a movement assisting unit (30). The brain wave detecting unit (10) detects biometric information in at least one brain region from among a plurality of brain regions that are selectable in accordance with a body part that is a target of function recovery or function improvement. The control unit (20) determines, based on the detected biometric information, at least one activity state in the brain including the location of the brain region(s) that is (are) activated in a subject while attempting to move the body part, and an activation level of such activated brain region(s). When the control unit (20) determines that the at least one activated state of the brain satisfies a predetermined condition, the movement assisting unit (30) executes a predetermined motion to assist movement of the body part.

Abstract: A finger exerciser includes: a frame on which a palm of a subject to be put; a movable section; a first fixing element; and a second fixing element. The movable is configured to move a first finger group of a subject. The first fixing element is configured to fix a position of the first finger group to the movable section. The second fixing element is configured to fix a position of a second finger group to the frame and has a band-like member including at least two attachment parts apart from each other in a longitudinal direction of the band-like member. The band-like member is attached to the frame at the attachment parts and includes a holder whose location to the frame is changeable. The band-like member is configured to hold the second finger group in a state where the band-like member is attached to the frame.

Abstract: An electroencephalogram measurement system includes an acquisition unit, a decision unit, and an output unit. The acquisition unit acquires electroencephalogram information representing an electroencephalogram obtained by an electrode unit placed on a region of interest that forms part of a subject's head. The decision unit makes a decision, based on the electroencephalogram information acquired by the acquisition unit, whether or not there are any artifacts. The output unit outputs the decision made by the decision unit.
