Samsung patents wearable that adjusts resistance based on joint movement
This device uses a sensor to track the angle of a user's joint and compares it to a set reference point. It then controls a motor to create varying levels of resistance, adjusting the strength based on how far the joint moves from that reference.
In the filing’s own words
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.
What exactly they claim (claim 1)
1. A wearable device, comprising: a motor including at least a first terminal and a second terminal; a motor driver circuit; a memory configured to store resistance force generation setting information indicating respective differences between a reference angle and respective joint angles and a corresponding relationship between respective duty ratios; a sensor; and a processor configured to: obtain, using the sensor, a joint angle of a user, determine a difference between the reference angle and the obtained joint angle, obtain a duty ratio of the respective duty ratios corresponding to the determined difference according to the resistance force generation setting information, and 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, wherein in the first control state, the first terminal and the second terminal of the motor are in an equipotential state such that a potential of the first terminal and a potential of the second terminal are equal to each other, and wherein in the second control state, the first terminal and the second terminal are electrically opened.
