WEARABLE DEVICE AND CONTROL METHOD THEREFOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18094052 titled 'WEARABLE DEVICE AND CONTROL METHOD THEREFOR

Simplified Explanation

The abstract describes a wearable device that includes a motor, motor driver circuit, memory, sensor, and processor. The device is designed to generate resistance force based on joint angles of a user.

  • The memory stores information about the desired resistance force settings for different joint angles.
  • The sensor measures the joint angle of the user.
  • The processor calculates the difference between the reference angle and the obtained joint angle.
  • The processor then determines the duty ratio (a measure of the motor's power) based on the calculated difference and the resistance force generation settings.
  • The processor sends a control signal to the motor driver circuit to switch the control state of the motor driver circuit between two states, based on the obtained duty ratio.

Potential applications of this technology:

  • Rehabilitation: The wearable device can be used in physical therapy to provide resistance force during joint movements, aiding in muscle strengthening and recovery.
  • Sports training: Athletes can use the device to simulate resistance during specific movements, enhancing their training and performance.
  • Virtual reality: The device can be integrated into virtual reality systems to provide haptic feedback, making the virtual experience more immersive and realistic.

Problems solved by this technology:

  • Lack of resistance in traditional wearable devices: This technology allows for the generation of resistance force, providing a more comprehensive and effective training or rehabilitation experience.
  • Customizable resistance settings: The memory stores information about different joint angles and their corresponding resistance force settings, allowing for personalized and targeted training or rehabilitation programs.

Benefits of this technology:

  • Enhanced training and rehabilitation: The resistance force generated by the device can help improve muscle strength, coordination, and range of motion.
  • Personalized experience: The device can be customized to individual users, providing tailored resistance force settings based on their specific needs and abilities.
  • Real-time feedback: The device can provide immediate feedback on joint angles and resistance force, allowing users to adjust their movements and technique accordingly.


Original Abstract Submitted

A wearable device, includes a motor, a motor driver circuit, a memory, a sensor, and a processor. The memory is configured to store resistance force generation setting information indicating a difference between a reference angle and each joint angle and a corresponding relationship between respective duty ratios. The processor is configured to obtain, using the sensor, a joint angle of a user and calculate a difference between the reference angle and the obtained joint angle. The processor is configured to obtain a duty ratio corresponding to the calculated difference according to the resistance force generation setting information. The processor is further configured to provide a control signal having the obtained duty ratio to the motor driver circuit to perform control such that a control state of the motor driver circuit is switched between a first control state and a second control state.
