Provided is a method and device for assisting walking of a user that may receive a pressure value applied to a sole of a user from a pressure sensor, acquire acceleration information associated with a movement of the user from an acceleration sensor, determine a gait phase based on the pressure value and the acceleration information, determine an assist torque corresponding to the determined gait phase, and control a driver to output the assist torque.

Systems and methods of processing raw electrocardiogram (ECG) waveform data of a patient into estimated real-time ECG waveform data. The method includes sensing at least one physical non-cardiac influence on the raw ECG waveform data, constructing a time domain computer model of the at least one physical, non-cardiac influence on the raw ECG waveform data, and adaptively filtering the raw ECG waveform data in the time domain using the constructed time domain computer model of the at least one physical non-cardiac influence on the raw ECG waveform data to form the estimated real-time ECG waveform data. The system can include an ECG device for collecting raw ECG waveform data, at least two ECG electrodes positioned on the patient and electrically coupled to the ECG device, and a processor coupled to the ECG device and configured to compute a time domain model of an artifact created by chest compressions.

A resuscitation device for assisting a rescuer in resuscitating a patient. A handheld computing/communication device may be configured for performing a non-resuscitation function during time periods when resuscitation is not required, the handheld device may be further configured to provide CPR prompts during time periods when used by a rescuer to assist in resuscitation, and a sensor may be provided to measure a parameter (e.g., chest acceleration) relevant to resuscitation. A CPR-assistance element may be configured to be applied to the patient and to communicate with the handheld computing/communication device.

A vibration module for applying vibrational tractions to a wearer's skin is presented. Use of the vibration module in headphones is illustrated for providing tactile sensations of low frequency for music, for massage, and for electrical recording and stimulation of the wearer. Damped, planar, electromagnetically-actuated vibration modules of the moving magnet type are presented in theory and reduced to practice, and shown to provide a substantially uniform frequency response over the range 40-200 Hz with a minimum of unwanted audio.

Technologies and implementations for wearable healthcare devices are generally disclosed. An example method performed by a wrist-wearable device includes: detecting, by a sensor, a physiological parameter of a user; determining, by a processor based on the physiological parameter, that the user is experiencing atrial fibrillation (AF); outputting, by a display, a visual signal indicating that the user is experiencing the AF; and transmitting, by a transceiver to a first external computing device, a first wireless signal indicating that the user experienced the AF.

A system includes a sequential compression device (SCD) used by a patient as part of a sequential compression therapy (SCT) protocol. The system also includes a computer device that determines whether the SCD is in use in substantially real time in compliance with the protocol. The computer device initiates a notification to a caregiver if noncompliance with the SCT protocol is detected.

Methods and systems for supporting and/or assisting users' movements include detecting, by one or more sensors integrated with a garment having two or more controllable regions, movement of a particular part of a user's body enclosed within the garment, measuring, by the one or more sensors, data that indicates the detected movement of the particular part of the user's body, determining, based on the measured data, an activity classification that indicates a future movement of the particular part of the user's body, identifying, based on the determined activity classification and by the one or more processors, a support configuration for the garment, and dynamically adjusting, by the one or more processors, at least one of an effective tension and an effective stiffness of at least one of the two or more controllable regions of the garment to provide the identified support configuration of the garment.

The present invention discloses neuro-stimulation systems and methods for affecting cardiovascular function, particularly for improving heart rate variability and treating arrhythmia.
