A light curing dental system comprising a light emitting tray that precisely distributes an optimal amount of curing light energy to internal, external and extra oral portions of the dental arch to cure a dental material. The light curing dental system generally includes a light source, a light emitting dental tray, an activation module and a photocurable dental material.

The present invention relates to a wearable smart device that controls, inhibit, and abates bacteria, virus, and fungi; The invention provides method and device to sanitize areas, spaces, surfaces, and items as well as human skin: The invention can be selectively used by an individual as desired to assist in control and abate the individual's hands, feet, footwear, or area: The invention is comprised of a kind of wearable smart device that forms a loop which can be placed around an individual's wrist or ankles, an off and on small light that serves as a switch at the upper side of the device and a universal base charging port by the side of the device used in charging the unit or the device can be stationary in one location and plug to the power source.

A bone implant includes a bore extending entirely through the bone implant. The bone implant also includes a light source to emit light onto bone adjacent the bone implant to stimulate bone growth and/or reduce bone loss.

Provided is a light therapy device capable of further maximizing a scattering effect, having enhanced durability, and exhibiting energy uniformity sufficient for use as a light therapy device.

Systems and methods for assessing compliance with position therapy. In an embodiment, position therapy is provided to a user while the user is wearing a position therapy device. The position therapy comprises, by the device, collecting positional data, determining positions of the user over a time period based on the positional data, and, when it is determined that the user is in a target position, providing feedback to the user to influence the user to change to a non-target position. In addition, the device stores a duration of use in its memory. The duration of use indicates a duration that the user has used the wearable position therapy device in each of one or more positions. An assessment of the user's compliance with the position therapy is then provided based, at least in part, on the duration of use.

A contact lens configured to decrease dark adaptation comprises one or more LEDs and directs light from the LED away from the fovea and toward the parafovea or perifoveal regions of the retina. In some embodiments, soft contact lens embedded with one or more arrays of microLEDs and electronics operating the LEDs is configured to be worn at night in order to inhibit dark adaptation and reduce oxygen consumption by the rods. The contact lens may be made of a single layer of a contact lens material or multiple layers sandwiching a flexible transparent plastic layer comprising the electronics and the LED arrays. The contact lens may be made of a hydrophilic hydrogel material that is biocompatible to the human cornea, or a silicone hydrogel material. The contact lens may be spherical and may provide refractive correction to the eye of the wearer.

Devices and methods for impinging light on tissue to induce one or more biological effects, and more particularly illumination devices and related methods that may be used for intranasal delivery of irradiation are disclosed. Exemplary illumination devices may include a light guide that is optically coupled with a light source, where the light guide may be configured for insertion along one or more intranasal passageways. In this manner, the light guide may provide irradiation of light to tissues along or near the upper respiratory tract to prevent and/or treat various infections and other tissue conditions thereof. Light guides may include flexible materials with suitable dimensions and/or shapes that allow the light guides to follow variable paths of intranasal passageways during use.

A light curing dental system comprising a light emitting tray that precisely distributes an optimal amount of curing light energy to internal, external and extra oral portions of the dental arch to cure a dental material. The light curing dental system generally includes a light source, a light emitting dental tray, an activation module and a photocurable dental material.

A wearable phototherapy display device comprises a display unit and a light source; wherein the display unit has an imaging plane, and the imaging plane is disposed directly in front of the human eye; the light source emits light having a peak wavelength between 400 nm and 1400 nm, and the light emitted by the light source is directed towards at least a part of a periocular region; the light source comprises a light-emitting surface, and the included angle between the light-emitting surface and the imaging plane is less than 30 degrees.

A wearable device for detection of a posture deviation of a body of a user, and to provide proper alignment thereon, comprises a resting pad adapted to cover a back region of the body of the user, wherein the resting pad includes an internal surface oriented towards the back region, and an external surface oriented away from the back region, a supporting unit adapted to be attached with the resting pad, at the external surface, wherein the supporting unit further includes a back stretcher adapted to be deformed through flexure, and a flexing mechanism adapted to cause the flexure of the back stretcher and a sensor unit configured to determine deviation in the posture of the body of the user. Further, the resting pad is made of a flexible material to accommodate the flexure of the back stretcher.
