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.

The invention provides a physical manipulation apparatus that is engageable with a skin surface of a human or animal subject. The apparatus may comprise a skin-engageable pad configured to conform to the morphology of a physical manipulation member such as a digit of a human therapist or a stylus tip of a chiropractic adjustment instrument. The skin-engageable pad may include a friction-inducing component in the form of a biomimetic dry adhesive. The apparatus may comprise a digit cover (110, 120, 130) configured at least partially to coyer a human digit. Instead, the apparatus may be configured as a skin patch having two release liners superimposed, respectively, on opposite sides of the skin-engageable pad. The skin patch may include indicia arranged to indicate a required orientation of the skin patch relative to a targeted anatomical feature such as a spinal segment, or a required direction of movement of the manipulation member.

Methods, systems and devices for reducing anxiety, including increasing relaxation and/or calm. In some variations these methods may include reducing anxiety, increase relaxation and/or calm by non-invasive temperature regulation of the frontal cortex prior to and/or during sleep. The subject may have an anxiety disorder, or may not have a diagnosed anxiety disorder.

A grip for sexual articles like butt-plugs, anal beads and dildos that enables better control through a flexible finger attachment that is collapsible for comfortable sitting while the sexual article is being used.

Devices and methods for assisting breathing in a subject are described. In one embodiment, a device includes a splint that can be used to apply negative distending pressure, i.e., outward pull, to one or both of the chest walls and/or the abdomen of a subject. The splint may include an air bladder that can be attached to the skin of the subject's chest and/or abdomen. When the air bladder is inflated, negative distending pressure is applied to the subject's chest and/or abdomen, thereby assisting or promoting respiration. The inflated air bladder may also apply a compressive force on the chest to facilitate expiration, and the removal of secretions in the airways.

Aspects of the cutaneous stimulation devices include a cutaneous stimulation module and a cutaneous association element configured to stably associate the module with a skin location. The cutaneous stimulation module may be an active or passive module. Also provided are methods of using the devices, e.g., in rehabilitation and/or pain mitigation applications.

An interface system in an exoskeleton includes a base support, a strap assembly, and posterior strut. The posterior strut has a vertical member defining a lower end connecting to the base support, and an upper end connecting to first and second transverse members extending in opposed directions from the vertical member. The first and second transverse members connect to the strap assembly. The interface system is adapted to receive and support an assistive device adapted to augment a user's performance and mitigate repetitive strain injuries.

Provided is an device for stabilizing the center of gravity and/or correcting distortion of the body simply through wearing of the appliance on a toe and conducting normal activities. The following invention is provided by the present invention. A cylindrical correction device that corrects distortion of the body, wherein: the correction device has inward-facing triangular-prism-shaped protrusions on the inner circumference; the triangles are inclined in one direction with respect to the circumference; and the correction device comprises a cylindrical elastic material having a diameter of 7-20 mm, a width of 5-10 mm, a thickness of 1-3 mm, and a hardness of 4-6.

An exoskeleton comprising a right hip attachment, a left hip attachment, a belt and a leaf-spring. The leaf-spring configured to couple two hips and apply torque from one respective hip to another respective hip based on the runner's movement and a right gear mechanism and a left gear mechanism, the right gear mechanism and the left gear mechanism comprising respectively of rack-and-pinion mechanism and configured to change an arch of the leaf-spring.
