An example of a system for providing patient care guidance to a caregiver based on ultrasound detection of blood flow includes a defibrillator including an electrode assembly and an output device, a portable computing device communicatively coupled to the defibrillator and including an output device, a Doppler shift waveform evaluation engine disposed at the defibrillator and/or the portable computing device, and a wearable ultrasound blood flow sensor configured to couple to a patient and the defibrillator and/or the portable computing device and to generate data signals representing a Doppler shift waveform. The engine is configured to receive the data signals representing the waveform, generate caregiver instructions according to a cardiac arrest protocol, analyze the waveform based on the received data signals, identify heart-induced blood flow based on the waveform analysis, and generate and provide caregiver instructions according to a non-cardiac arrest protocol based on the identified heart-induced blood flow.

A method, performed by a wearable device, of outputting a torque includes obtaining a first angle of a first joint of a first leg of a user and a second angle of a second joint of a second leg of the user, calculating a first adjustment angle, based on an offset angle set for the first angle and the first joint, determining a first state factor associated with the first angle and the second angle, based on the first adjustment angle and the second angle, determining a first value of a parameter for adjusting at least one of a magnitude, a direction, and timing of a torque to be output, determining a first torque value, based on the first state factor and the first value of the parameter, and controlling a motor driver of the wearable device to output the first torque value.

Two vertical front posts and two vertical rear posts are mounted on a flat platform of the automated device. The front posts mounted in the horizontal guide are symmetrically moved by the spacing adjustment mechanism within the range between the position of the joined front posts to a dimension between their inner surfaces equal to the width of the wheelchair, and the moved apart position to a dimension where the width dimension of the wheelchair is located between the mechanical legs suspended on the front posts. On the inner surfaces of the front posts, there are vertical guides with a screw drive mechanism for pelvic height adjustment. The mechanical legs girdle the patient's lower limbs from the outside by pelvic control units that induce a symmetrically alternating movement of the hip joint hinges in both mechanical legs with ellipsoid trajectories, and by adjustable thigh and shin connectors and foot connectors.

A human-computer interface system having an exoskeleton including a plurality of structural members coupled to one another by at least one articulation configured to apply a force to a body segment of a user, the exoskeleton comprising a body-borne portion and a point-of-use portion; the body-borne portion configured to be operatively coupled to the point-of-use portion; and at least one locomotor module including at least one actuator configured to actuate the at least one articulation, the at least one actuator being in operative communication with the exoskeleton.

A massage chair and a method of operating a massage chair, in which operations are controlled by executing artificial intelligence (AI) algorithms and/or machine learning algorithms in a 5G environment connected for Internet-of-Things. The method of operating a massage chair includes obtaining, from a user terminal, first information corresponding to geographic information generated by the user terminal, obtaining, from the user terminal, second information corresponding to motion information generated by the user terminal, obtaining, from the user terminal, third information corresponding to usage information of the user terminal, generating fourth information as additional information using one or more among the first information, the second information, and the third information, and determining an optimal driving mode with respect to a user of user terminal by using the first information to the fourth information.

A system and method are disclosed that allows a practitioner to rotate a human subject in three different axes of rotation, independently from one another and without limitation on the degree of rotation, which allows for the treatment of various systems of the human subject.

A medical device for providing oscillatory motion to an individual is provided. The medical device includes a holder that can hold one or more body parts of an individual and an oscillatory mechanism that can transmit an oscillating force to the holder. The medical device includes one or more sensors that provide information about the individual and one or more compliant components that are configured to allow movement of the one or more body parts that deviates from a movement of oscillation. The oscillating mechanism can dynamically change a frequency of an oscillation based on feedback from the one or more sensors. The oscillating mechanism can also dynamically change an amplitude of the oscillation based on feedback from the one or more sensors.

An external defibrillator system includes one or more compression sensors; one or more physiological sensors; and at least one processor. The at least one processor is configured to: receive and process chest compression signals and physiological signals from the sensors, determine values for chest compression depth and/or chest compression rate based on the received chest compression signals, determine a trend of at least one physiological parameter over a period comprising multiple chest compressions based on the received physiological signals, adjust a target chest compression depth and/or target chest compression rate based on the determined trend of the at least one physiological parameter, compare the determined values for chest compression depth and/or chest compression rate to the adjusted target compression depth and/or the adjusted target compression rate, and provide feedback about the quality of chest compressions performed on the patient.

A walking assist device includes: a pair of right and left handles that are movable back and forth with respect to a frame in accordance with arm swing performed during walk of a user; rails on which the handles are provided and which limit movement of the handles in a movable range in accordance with arm swing performed during the walk of the user; a handle information acquisition unit that acquires information related to movement of the handles; and a control unit that controls a drive unit in accordance with the information from the handle information acquisition unit.

A pool or spa system includes networked pool or spa devices that can be dynamically configured with network address by a controller. The controller can transmit a device discovery request on a network and can receive a discovery response from pool or spa devices that require a network address. The system determines and assigns the network addresses for the pool or spa devices based on unique device identifiers associated with the responding pool or spa devices. The network addresses assigned to the pool or spa device are transmitted to the pool or spa device to be used by the pool or spa devices to communicate with the controller over the network. The system can be used to discover and assign addresses to various types of pool or spa devices, such as pumps, underwater lights, chlorinators, water feature controllers, remote controllers, and/or other types of devices.
