A system includes a mobile device having one or more cameras to take images; a sensor detecting reflected light from one or more lasers and a diffuser to detect object range or dimension; code for motion tracking, environmental understanding by detecting planes in an environment, and estimating light and dimensions of the surrounding based on the one or more lasers; code to estimate a three-dimensional (3D) volume of an object from multiple perspectives and from projected laser beams to measure size or scale and determine locations of points on the object's surface in a plane or a slice using time-of-flight, wherein positions and cross-sections for different slices are correlated to construct a 3D model of the object, including object position and shape; the device receiving user request to select a content from one or more augmented, virtual, or extended reality contents and rendering a reality view of the environment.

A wearable upper limb rehabilitation training robot with precise force control includes a wearable belt, a multi-degree-of-freedom robot arm, and a control box. The robot is worn on the waist of a person by using a belt, and driven by active actuators, to implement active and passive rehabilitation training in such degrees of freedom as adduction/abduction/anteflexion/extension of left and right shoulder joints and anteflexion/extension of left and right elbow joints. In addition, a force/torque sensor is mounted on a tip of the robot arm, to obtain a force between the tip of the robot arm and the human hand during rehabilitation training as a feedback signal, to adjust an operating state of the robot, thereby realizing the precise force control during the rehabilitation training.

The pain-relieving apparatus has a housing, a stimulating surface, user inputs, and a plurality of ports, such as a battery port and a transcutaneous electrical nerve stimulation (TENS) output connector. The stimulating surface may include a suction ring, vacuum apertures, vibration stimulators, a plate, heat and cold transducer elements, and medicinal holders to provide various approaches for relieving pain. The pain-relieving apparatus may also have a sound speaker for producing nerve stimulating sounds.

A device which utilizes low intensity extracorporeal shock therapy for purposes of treating soft tissue damage, cellulite reduction, or erectile dysfunction, to permit a simple, inexpensive, robust, home use solution which permits self-applied treatment for various parts of the user's body with a form factor, display, information, guidance, tutorials and training, marketing communication and purchase opportunities, viewing angle, timers, annunciators, sound attenuation, and payment options which provide an untrained amateur user with all tools and guidance necessary to properly, effectively, safely and affordably self-administer treatments.

An artificial muscle chair device includes a plurality of artificial muscles embedded in a chair. Each artificial muscle includes a housing having an electrode region and an expandable fluid region. A first electrode and a second electrode each disposed in the electrode region of the housing. The artificial muscle chair device further includes a dielectric fluid disposed within the housing. The first and second electrodes electrostatically attract, inflating the expandable fluid region with dielectric fluid and thereby applying selective pressure to an outer surface of the chair.

A modular bed includes a frame assembly, a plurality of elongated support units, and at least one vibration assembly including a rack, a stretchable web, and a vibration motor. The rack is detachably mounted on two selected adjacent ones of the elongated support units. The stretchable web has a central portion suspended across a lower opening of the rack. After the through bore is stretched to permit insertion of a positioning plate of the vibration motor, resilient retraction of the through bore causes a neck portion of the vibration motor to be trapped in the through bore with a motor body and the positioning plate of the vibration motor to be in abutting engagement with upper and lower surfaces of the stretchable web, respectively.

A spinal therapy apparatus includes one or more manipulating assemblies. In some examples a first manipulating member is arranged to engage a spine at a first vertebral area between a spinous process and a transverse process on a first side of a spine and a second manipulating member is arranged to engage the spine at a second vertebral area between a spinous process and a transverse process on the first side of the spine. The first and second manipulating members are coupled together at their proximal ends to permit the first and second manipulating members to be driven simultaneously and the coupling permits motion of the first and second manipulating members relative to one another in an axial direction. In other examples a drive system is adapted to drive first and second manipulating members simultaneously and independently. The disclosure also relates to a spinal therapy bed including such manipulating assemblies and methods of using and training spinal therapy devices.

A corporeal compression system for use in applying compression to a patient positioned upon a supporting surface has an overlay, and a gas supply system. The overlay includes flexible sheet material that is arranged into at least two layers to define an internal region therebetween, an inlet orifice that opens into the internal region, and restraints that, in use, locate and restrain edge portions of the flexible sheet material. The layers are repositionable with respect to each other such that the sheet material can assume a deflated state in which the volume of the internal region is a minimum In use of the corporeal compression system, the flexible sheet material of the overlay is draped over the patient, the flexible sheet material is restrained relative to the support surface by the restraints, and the gas supply system is operable to deliver gas to increase the volume of the internal region from the deflated state and establish an elevated pressure within the internal region, thereby compressing the patient between the posterior layer of the overlay and the supporting surface.

The negative pressure generator includes a chamber body with a suction nozzle; a piston, arranged inside the chamber body; and a driving device configured to drive the piston to reciprocated move inside the chamber body so as to generate negative pressure at the suction nozzle.

A knee movement support device according to an embodiment of the present disclosure is a knee movement support device attached to a leg of a user, and includes: an upper leg link fastened to an upper leg of the user; a lower leg link fastened to a lower leg of the user; and an interval adjusting portion disposed between the upper leg of the user and the upper leg link or between the lower leg of the user and the lower leg link.
