摘要： An adaptive control method and system for an upper limb rehabilitation robot based on a game theory and surface Electromyography (sEMG) is disclosed. A movement trajectory that a robot is controlled to run within a training time is designed during subject operation. An sEMG-based Back Propagation Neural Network (BPNN) muscle force estimation model establishes a nonlinear dynamic relationship between an sEMG signal and end force by constructing a three-layer neural network. A human-computer interaction system is analyzed by the game theory principle, and a role of the robot is deduced. The control rate between the robot and a subject is updated by Nash equilibrium, and adaptive weight factors of the robot and the subject are determined. The robot adaptively adjusts the training mode thereof according to a movement intention of the subject during operation and a weight coefficient obtained by the game theory principle.

摘要： The present invention relates to an electric massage device capable of gradually increasing a massage force during an outward stroke, mainly comprising a massage module and a control module. In the outward stroke, the control module applies a driving current to the electromagnetic driving unit, and the driving current is gradually increased with an elapsed time or a stroke displacement of the output shaft. In a return stroke, the control module deenergizes the driving current or applies a weak reverse current less than one-fifth of the driving current. At the beginning of the outward stroke, the massage force is weak due to the smaller driving current and hence would not cause skin hurt. At the end of the outward stroke, the massage force is strong due to the greater driving current and hence produces a deep muscle massage effect.

摘要： A modular passive-to-active exoskeleton system utilizes motor unit modules, an electromagnetic-clutch power transmission system, and biometric control. The passive exoskeleton has a stamina-increasing “chairless chair” function and optional use of magnetic ball-and-socket joints and knee torsion springs. To convert the exoskeleton system into an active robotic wearable device, modular attachments allow for motor units to be securely connected to the exoskeletal frame. An exoskeleton system may contain a knee motor unit that has a transmission system with an electromagnetic clutch that enables a passive mode, active mode, and/or hybrid mode. The motor units are controlled using wireless biometric motion sensors that measure limb joint angle and muscle activity. These motor units also communicate via wireless transmission with a central processing unit of the exoskeleton. This central processing unit serves as a gateway for user feedback from an Internet-of-Things (IoT) device, such as a smartphone, tablet, computer, etc.

摘要： Devices, systems, and methods herein relate to electromyography (EMG) that may be used in diagnostic and/or therapeutic applications, including but not limited to electrophysiological study of muscles in the body relating to neuromuscular function and/or disorders. Sensor assemblies and methods are described herein for non-invasively generating an EMG signal corresponding to muscle tissue where the sensor may be positioned directly on a surface of the muscle tissue including any associated membrane (e.g., mucosal, endothelial, synovial) overlying the muscle tissue. A sensor assembly may include one or more pairs of closely spaced, atraumatic electrodes in a bipolar or multipolar configuration. The first and second electrodes may be applied against a surface of muscle tissue (that may include a membrane overlying the muscle) and receive electrical activity signal data corresponding to an electrical potential difference of the portion of muscle between the electrodes.

摘要： Disclosed are powered gait assistance systems that include a controller, sensors, and a torque applicator (motor, spring, etc.) coupled to a patient's hips, thighs, knee, lower leg, ankle, and/or foot and operable to apply assistive torque to the patient's leg joint(s) to assist the patient's volitional joint actuating muscle output during selected stages of the patient's gait cycle, such that the applied torque improves the patient's leg posture, muscle output, range of motion, and/or other parameters over the gait cycle. The sensors can include a torque sensor that measures torque applied, one or more joint angle sensors, a ground contact sensor that measures ground contact of the patient's foot, and/or other sensors. The controller can determine what stage of the patient's gait cycle the patient's leg is in based on sensor signals and cause the torque applicator to apply corresponding torque to the joint(s) based on the gait cycle stage, sensor inputs, and known patient characteristics.

摘要： A human body support has a plurality of electrodes arranged in an array and spaced longitudinally with respect to the human body. The array extends from an inferior position to a more superior position along the body. A sensor measures a parameter of the human body that is capable of indicating the presence of drowsiness. A controller has an input connected to the sensor for receiving a signal representing the sensed parameter and has outputs connected to each of the electrodes. The controller detects whether the sensed parameter is within a range indicating the presence of drowsiness and applies a wave of electrical stimuli against the human body in response to detection of a sensed parameter within the range. The electrical stimuli cause periodic tightening and relaxing of proximate muscles as the wave progresses in a direction from an inferior location on the human body toward a more superior location.

摘要： Disclosed are powered gait assistance systems that include a controller, sensors, and a motor coupled to a patient's thigh and lower leg and operable to apply assistive torque to the patient's knee joint to assist the patient's volitional knee pivoting muscle output during selected stages of the patient's gait cycle, such that the assistive torque applied by the motor improves the patient's leg posture, muscle output, range of motion, and/or other parameters over the gait cycle. The sensors can include a torque sensor that measures torque applied by the motor, a knee angle sensor, a foot sensor that measures ground contact of the patient's foot, and/or other sensors. The controller can determine what stage of the patient's gait cycle the patient's leg is in based on sensor signals and cause the motor to apply corresponding assistive torque to the knee based on the gait cycle stage, sensor inputs, and known patient characteristics.
