  • Patent number: 10852874
    Abstract: An object may rest on top of a sensor structure. Multiple 3-axis load sensors may be embedded in the sensor structure, and may take measurements of a force created by a human user touching the object. The direction of the force may fluctuate slightly, due to tiny shaking movements of the user's hand or finger while the hand or finger touches the object. These tiny shaking movements may occur even in a normal, healthy person. Based on these measurements of fluctuating force that are taken by the load sensors, a computer may calculate three-dimensional spatial coordinates of a point at which the user is touching the object.

  • Patent number: 8403827
    Abstract: An endoscopic insertion aid includes a tube member, a pipeline and a plurality of balloons. The tube member allows an insertion section of an endoscope to be inserted therethrough, and guides the longitudinal movement of the insertion section. The pipeline is provided in the tube member, and communicates with a supply/discharge unit to supply a fluid to or discharge the fluid from the distal end of the tube member. The balloons are disposed on the outer periphery of the distal end of the tube member longitudinally along the tube member, communicate with the pipeline, and inflate/deflate in accordance with the supply/discharge of the fluid via the pipeline. The balloon disposed on the distal side of the tube member is inflated to have an outside diameter larger than that of the balloon disposed closer to the proximal side than the balloon disposed on the distal side when the balloons are inflated.

  • Patent number: 7935047
    Abstract: An endoscope system, serving as a double-balloon endoscope system, includes an endoscope apparatus for examinations using an endoscope, a shape detection apparatus used in combination with the endoscope apparatus, and a balloon controller. The shape detection apparatus detects positions of respective points in an insertion section of the endoscope, estimates the shape of the insertion section on the basis of the detected positions, and displays an image representing the modeled shape of the insertion section corresponding to the estimated shape. The balloon controller controls balloons, serving as insertion support units, attached to the endoscope. The shape detection apparatus detects the states of the balloons controlled through the balloon controller and reflects the controlled states of the balloons on an image representing the shape of the insertion section. With this arrangement, the inflation/deflation states of the balloons and the insertion state can be visually confirmed in real time with ease.
