A multimodal human-robot interaction system for upper limb rehabilitation, including an electroencephalography signal acquisition and processing module, a robot module, a comprehensive affected upper limb muscle signal acquisition and processing module, a rehabilitation training evaluation module, and a virtual reality module. The electroencephalography signal acquisition and processing module captures a motion intention of a patient by means of electroencephalography signals to trigger rehabilitation training. The robot module assists an affected upper limb with rehabilitation exercise. The comprehensive affected upper limb muscle signal acquisition and processing module acquires and obtains a comprehensive assessment of the affected upper limb. The rehabilitation training evaluation module is used for processing and analyzing the comprehensive assessment of the affected upper limb, so as to obtain a quantitative evaluation of the affected upper limb during rehabilitation training. The virtual reality module is used for displaying a virtual environment for rehabilitation training, and interacting with the patient.

A method removing artifacts from neural signals comprises receiving electroencephalography (EEG) data from an EEG system and providing the EEG data to a unified artifact removal framework for cleaning artifacts. The EEG data is provided to a first cleaning framework utilizing the first reference to clean first artifacts from the EEG data, and the outputting the EEG data from the first cleaning framework to a second cleaning framework. The second cleaning framework may operate in a similar manner utilizing second reference to clean second artifacts from the EEG data. This general process may be repeated as desired to clean various artifacts from EEG data, when a suitable reference for the artifacts to be removed is utilized. The frameworks utilize H∞ method or filtering involving a H∞ adapting rule to properly weigh the reference, and combining the subsequent output with incoming EEG data results in the desired removal of artifacts.

Delivering vibratory therapy to a user may include using a system with a first transducer adapted to emit a first transcutaneous vibratory output; a second transducer adapted to emit a second transcutaneous vibratory output; and a processor in electronic communication with a user interface, the first transducer, and the second transducer, wherein the user interface accepts a user target state. The processor may be programmed to (i) generate a first transcutaneous vibratory output pattern comprising a first perceived pitch, a first perceived beat, and a first intensity; (ii) generate a second transcutaneous vibratory output pattern comprising a second perceived pitch, a second perceived beat, and a second intensity; (iii) cause the first transducer to emit a first transcutaneous vibratory output based on the first transcutaneous vibratory output pattern; and (iv) cause the second transducer to emit a second transcutaneous vibratory output based on the second transcutaneous vibratory output pattern.

A wearable safety system for either diving, harsh or anoxic environments, or for individuals at high risk for respiratory and/or cardiac failure is disclosed. The wearable safety system includes biometric monitoring and provides cardiac and/or respiratory support in the event that the wearer experiences cardiac and/or respiratory failure. There are different configurations of the wearable safety system designed to work with different use cases, and to provide different levels of protection. In the case of diving, the wearable safety system additionally utilizes data collected by the dive computer to advise a rescue diver as to the best course of action in managing an unconscious diver's ascent and can also inflate the diver's buoyancy control device (BCD) or onboard personal flotation device.

A massage system for a seat of a vehicle includes a drive motor, a sliding member having a hollow pillar shape, a first end of the sliding member being blocked by a plate member and a second end of the sliding member being opened, a housing member having a hollow pillar shape, a first end of the housing member being blocked by a partition and a second end of the housing member being opened, and a drive gear module operably connected to the drive motor, wherein at least one roller member is extended toward the housing member at an edge of the plate member, and at least one cam protruding toward the sliding member is formed at a circumference of the partition, wherein a cam profile is formed at a surface of the cam.

Split-crank pedaling devices and methods of operation support patient use and rehabilitation, particularly for stroke patients. A split-crank pedaling device includes first and second crank assemblies. First and second motors are operably connected to the first and second crank assemblies. A first shaft sensor produces an indication of a position of the shaft of the first crank assembly. A second shaft sensor produces an indication of a position of the shaft of the second crank assembly. A controller is communicatively connected to the first and second motors and the first and second shaft sensors and calculates a phase error between the positions of the first and second shafts and a predetermined phase relationship between the first and second shafts. The controller operates at least one of the first motor or the second motor to provide a supplemental torque to one of the first crank assembly and the second crank assembly.

An auricular peripheral nerve field stimulator includes at least one therapy electrode configured for percutaneous insertion into an auricle of a human ear near at least one neurovascular bundle, and an electrical stimulation device electrically coupled to the at least one therapy electrode, the electrical stimulation device programmed to generate and deliver electrical stimulation signals, with defined stimulation parameters, to the percutaneously inserted at least one therapy electrode to stimulate at least one auricular peripheral nerve field within the auricle, the defined stimulation parameters including a defined signal amplitude, a defined pulse frequency, a defined pulse width, a defined duty cycle and a defined stimulation signal duration.

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.

A method to improve neurologically-intact survival rates after cardiac arrest may include performing CPR on an individual in cardiac arrest while the individual is in a supine position in general alignment with a horizontal plane. The method may include elevating the individual's head, shoulders, and heart relative to the individual's lower body while the individual's lower body remains generally aligned with the horizontal plane to cause blood to actively drain venous blood from the brain to reduce intracranial pressure. The method may include performing chest compressions on the individual and actively decompressing the individual's chest while the individual's head, shoulders, and heart are elevated.
