  • Patent number: 10121066
    Abstract: A method of calculating the stress on a joint by determining when a joint angle is outside the normal range of motion for the joint. Applications include analysis of elbow joint stress for baseball pitchers, for example to mitigate the risk of injury to the ulnar collateral ligament (UCL). During a movement such as a baseball pitch, sensor data is collected to track the position, orientation, or motion of body segments; joint angles are derived from this sensor data. Joint angles are then compared to a range of motion, which may be measured for each individual. Joint stress contributions from movements that exceed the range of motion may be combined over time to calculate cumulative joint fatigue. This joint fatigue measure may for example be used for pitchers to quantify recovery periods (days off) and future workloads (such as maximum pitch counts).

  • Patent number: 9974706
    Abstract: A driving device includes a wearable mechanism that is worn on a wearing part, an actuator that drives the wearable mechanism, and first and second force sensors that are provided on the wearable mechanism and detect a force. The first and second force sensors are provided at positions at which a first detected value obtained from the first force sensor and a second detected value obtained from the second force sensor are changed in response to a motion of the wearing part. When a difference between the first and second detected values is less than a pre-decided first threshold value and the first or second detected value is greater than a pre-decided second threshold value, the actuator drives the wearable mechanism so that the second detected value is constant.

  • Patent number: 8255079
    Abstract: A grasp assist device includes a glove portion having phalange rings, contact sensors for measuring a grasping force applied by an operator wearing the glove portion, and a tendon drive system (TDS). The device has flexible tendons connected to the phalange rings for moving the rings in response to feedback signals from the sensors. The TDS is connected to each of the tendons, and applies an augmenting tensile force thereto via a microcontroller adapted for determining the augmenting tensile force as a function of the grasping force. A method of augmenting a grasping force of an operator includes measuring the grasping force using the sensors, encoding the grasping force as the feedback signals, and calculating the augmenting tensile force as a function of the feedback signals using the microcontroller. The method includes energizing at least one actuator of a tendon drive system (TDS) to thereby apply the augmenting tensile force.

  • Patent number: 7862522
    Abstract: A Sensor glove is an instrument, in the same way that a piano is an instrument. The Sensor glove is purchased and the owner then learns to use it and the sensors therein to develop the performance of a sound, character or model, or to “conduct” or “play” the sensor movements and experience the response of the model in real time. Several performers with a number of the Sensor glove can control over 200 motors or hundreds of control points on a character at one time, manipulate audio data, or computer images etc. The characteristics of the sensors on the gloves can be adjusted to the needs and demands of the wearer or the many performer and wearers in those venues where multiple performers are used with many gloves to control or produce the motions and sounds of many distinct characters in a screen play.

  • Publication number: 20100130895
    Abstract: An apparatus for passive extension and flexion of at least one finger of a patient with an upper arm unit, a lower arm unit, and at least one connective line. The apparatus is configured such that elbow extension of the patient promotes finger flexion. This is accomplished by taking advantage of the geometry of the arm, where the distance from a point on the patient's humeral area to the patient's fingers is greater when the patient's arm is in extension than when it is in flexion. In one aspect, the upper arm unit is configured to connect to a portion of the patient's arm between the patient's elbow and shoulder and the lower arm unit is configured to connect to a portion of the patient's arm intermediate the patient's hand and elbow.
