  "title": "How Sensors Measure Body Joint Movement Across Different Sections",
  "original_title": "Sensor array spanning multiple radial quadrants to measure body joint movement",
  "summary": "This patent describes a system of bendable and stretchable electromagnetic sensors placed around a body joint in four distinct sections to precisely track its movement.",
  "what_it_does": "This invention uses an array of special sensors to measure how a body joint moves. It includes at least four \"longitudinal electromagnetic energy sensors\" that are designed to stretch and bend as the joint moves, with each sensor placed in a different quarter, or \"radial quadrant,\" around the joint. For example, imagine four flexible strips wrapped around your knee, each covering a different side. The system also includes other \"radial electromagnetic energy sensors\" that collectively span the joint, with their axes pointing towards a common center. By measuring the changes in electromagnetic energy passing through these sensors as the joint moves, the system can figure out exactly how the joint is bending or twisting.",
  "what_it_does_not_cover": [
    "Does not cover systems that use fewer than four longitudinal electromagnetic energy sensors to span the body joint.",
    "Does not cover sensors that measure joint movement using only accelerometers, without the specific bending and/or stretching electromagnetic sensors.",
    "Does not cover sensor arrays where the longitudinal axes of the radial electromagnetic energy sensors do not converge.",
    "Does not cover measuring movement of objects or structures that are not body joints.",
    "Does not cover sensors that are not electromagnetic energy sensors, even if they bend or stretch."

  "abstract": "This invention is a sensor array which longitudinally spans a body joint in order to measure movement of that body joint. In an example, this sensor array can comprise four longitudinal sensors which span the body joint in four different radial quadrants, respectively. In an example, this sensor array can comprise six longitudinal sensors which span the body joint in six different radial hextants, respectively. In an example, this sensor array can further comprise a first accelerometer which is proximal to the body joint and a second accelerometer which is distal to the body joint.",
