  • Patent number: 9766115
    Abstract: A balance ability measurement apparatus acquires load information on weight of a user as measured during a period of a stand-up movement which is a period of time from when the user starts the stand-up movement to when the user stabilizes standing posture. Based on the load information, the balance ability measurement apparatus calculates load change information on change in the weight of the user. Further, based on the load information, the balance ability measurement apparatus calculates left-right displacement information on displacement of the user in left-right direction. Based on the load change information and the left-right displacement information, the balance ability measurement apparatus calculates a balance ability evaluation value on balance ability of the user.

  • Patent number: 9659322
    Abstract: A pressure sensor measures the surface pressure distribution of a body supported by a surface, for example a person lying on a mattress. In one approach, a pressure mapping system acquires a customer's pressure map using a reference mattress and presents this pressure data in the form of a pressure map. The pressure map measurement data is then analyzed to determine body characterizing parameters such as body mass index, contact area and average peak pressure. The pressure map measurements are then located on a mattress category grid that has been referenced and aligned to a large population sample of measurements taken with a reference mattress. Alternatively, the pressure map measurements are matched to a physical profile category within a database. Each category provides ranked mattress recommendations based on selection and ranking criteria derived from pressure map data obtained from a large sample of test subjects.

    Abstract: Systems and methods for determining a user's static weight while standing as well as the user's load bearing weight. A sensor module with multiple sensors is placed inside a user's shoe and biometric data is gathered from the sensors when the user stands and when the user takes a step or walks. The data is used to generate data loops as the various sets of data are plotted against each other. The loops obtained from the data are then compared against stored loops previously obtained. Using the biometric loop baseline data, it can be determined whether the user has lost or gained weight, whether a specific load bearing weight condition is worsening while standing and while walking or running. The system can also determine whether a specific load bearing weight condition is improving or worsening.

  • Publication number: 20110197668
    Abstract: An apparatus comprised of a plurality of engagement structures independently movable along a longitudinal axis to initially engage a mid-foot region of a foot is described. A center structure or a first set of engagement structures engage the foot in a mid-foot region, and one or more peripheral engagement structures engage the plantar surface in regions surrounding the mid-foot region independent from the structure(s) engaging the mid-foot region. Positional information about the engagement structures is obtained, and a surface map from the positional information is constructed, to determine a profile or contour for an orthotic device in which the foot is in a restored bone state.

  • Publication number: 20110162238
    Abstract: Disclosed are methods and systems for design of a foot orthotic, and a foot orthotic device designed in accord therewith. More specifically described is an individualized foot orthotic device to correct and/or restore the ideal alignment and/or positioning of foot structures. In the method, sequential pressure is applied to regions on a plantar foot surface, and positional information is obtained about each region. Based on the positional information, an orthotic profile is determined, for design of one or more custom, individualized foot orthotic devices for a subject.

  • Publication number: 20110146396
    Abstract: A method for analyzing a gait pattern includes: measuring, by a plurality of force sensing resistor (FSR) sensors, foot pressure values, and outputting the measured foot pressure values, respectively; searching for a maximum pressure local area in which the sum of the output values from the FSR sensors included in each of a plurality of pressure local areas is maximized; calculating a center of pressure (COP) with respect to the detected maximum pressure local area; and analyzing a gait pattern by adding the calculated COP to the trajectory of COPs.

  • Patent number: 7891259
    Abstract: A human dummy system for evaluating the comfort of a seat comfort includes sensor units and a data processing unit. The sensor units are attached to the relevant joints of a human dummy, and detect the angles of the relevant joints. The data processing unit calculates information about relative locations of adjacent joints on the basis of the information about the angles of the relevant joints, and calculates the absolute location of a specific joint through coordinate system transformation between the information about relative locations and the joints of the human dummy.

  • Patent number: 7860607
    Abstract: The joint rotational angles of joints 9, 11 and 13 of each leg 2 of a bipedal walking body 1 are detected to grasp the positions/postures of the corresponding rigid bodies 10, 12 and 14 of each leg 2 on a leg plane passing the joints 9, 11 and 13 of each leg 2. At the same time, the acceleration of a reference point (the origin of a body coordinate system BC) of the bipedal walking body 1, the floor reaction force acting on each leg 2 and the position of an acting point thereof are grasped in terms of three-dimensional amounts. Two-dimensional amounts obtained by projecting the acceleration, the floor reaction force and the position of the acting point thereof, and the positions/postures of the corresponding rigid bodies of each 2 onto the leg plane are used to estimate the moments acting on joints of each leg on the basis of an inverse dynamic model.
