Abstract: A load suspension and weighing system for a removable reservoir unit of a portable dialysis machine includes a centrally located flexure assembly. The flexure assembly includes magnets and a number of flexure rings which allow for movement of the magnets about a fixed circuit board. Sensors in the circuit board sense changes in the magnetic field as the magnets move in relation to the circuit board. The magnetic field changes produce a voltage output which is used by a processor to generate weight calculations. The top of the flexure assembly is attached to the interior of the dialysis machine. The entirety of the reservoir unit is suspended by a first internal frame that is attached to the bottom of the flexure assembly. Having a single flexure assembly positioned above the reservoir unit provides more accurate weight measurements while also preventing damage to the assembly from water spillage.

Abstract: A force sensor according to embodiments includes a light-emitting unit, a pair of first light detectors, a reflector, and a first frame. The light-emitting unit emits diffuse light. The first light detectors are arranged in a first direction with the light-emitting unit interposed therebetween. The reflector is arranged to face the light-emitting unit on an optical axis of the light-emitting unit and reflects the diffuse light emitted from the light-emitting unit toward the first light detectors. The first frame is deformed in the first direction so that a reflection range of the diffuse light reflected by the reflector is displaced in the first direction.

Abstract: A high-accuracy load measuring apparatus capable of enlarging a measurement range includes a loading section provided at one end of a long and narrow beam. A support supports the beam at a side closer to the other end of the beam than the loading section. A displacement sensor includes a capacitive sensor and is provided to measure a displacement of the loading section. The beam includes a pair of long and narrow plate-like legs arranged in parallel while being spaced apart in a thickness direction and a connecting portion connecting ends of the plate-like legs at a side of the loading section. The beam is supported on the support to have a changeable length between a supported position by the support and the loading section. Each plate-like leg includes a slot, which is a long and narrow hole formed along a length direction in a widthwise central part.
