Device for printing three-dimensional objects using an energy-field projection system. In operation, energy is projected into a print medium according to a four dimensional (4D) energy-field function for exposing the print-medium to a threshold energy-intensity level that causes the print medium to harden in the shape of a three-dimensional object.

The inventive concept relates to an apparatus for phototherapy treatment of a pet. The apparatus includes a grippable main body having a pair of heads for respectively emitting light, a plurality of first LED modules respectively disposed in the pair of heads, wherein the plurality of first LED modules irradiate light of a specific wavelength toward a skin and an external auditory meatus of the pet, respectively, at least one second LED module disposed in one of the pair of heads, wherein the at least one second LED module irradiates light of a wavelength different from the wavelength of the light of the plurality of first LED modules toward the external auditory meatus of the pet, and a controller disposed in the main body to control the first LED module and the second LED module to respectively irradiate the light.

Four dimensional (4D) energy-field package assembly for projecting energy fields according to a 4D coordinate function. The 4D energy-field package assembly includes an energy-source system having energy sources capable of providing energy to energy locations, and energy waveguides for directing energy from the energy locations from one side of the energy waveguide to another side of the energy waveguide along energy propagation paths.

An oral care illumination device (30) includes a mouthpiece (300) and a backlight module (320). The mouthpiece is adapted to fit at least a portion of a user's mouth. The backlight module is coupled to the mouthpiece and includes at least one light source (320), a light guide plate (310) configured to receive light from the at least one light source, including a curved light emitting surface (360) and a plurality of microstructures (350), and at least one reflector (340) to redirect light through the light guide plate. The plurality of microstructures, the curved light emitting surface, and the at least one reflector alter a propagation of light from the at least one light source through the light guide plate to illuminate a predetermined area of the user's mouth with a desired light distribution.

The invention provides a tip that permits therapeutic electromagnetic energy systems to deliver multiple beams of overlapping, partially overlapping, and non-overlapping electromagnetic energy in the treatment of tissue disorders and conditions. The tip finds use with laser systems, intense pulsed light systems, LED systems, radiofrequency systems, and microwave systems.

Disclosed is a lighting device for bright therapy and dark therapy, comprising: a light source part including a red light source, a green light source and a blue light source; a power supply part supplying a power to the light source part; and a controller adjusting, by controlling the power supply part, a bio illuminance to allow melatonin suppression value to exceed a first reference value during morning hours and to allow the melatonin suppression value to be less than a second reference value while maintaining a visual illuminance over a predetermined value during evening hours.

Disclosed is a device that utilizes a light-field display to project a virtual continuum of real world perspectives of a natural scene to a plurality of observer viewpoints to simulate a natural environment. An observer perceives different perspectives as he or she moves through the simulated environment just like the observer would as if he or she were in a natural environment.

An apparatus including a light source provides for intracranial treatment of a tissue region of a brain of a patient. The intracranial treatment apparatus comprises an outer shaft having a proximal end and a distal end for positioning within the tissue region of the brain. The outer shaft defines a lumen extending between the proximal end and the distal end of the outer shaft and having at least one aperture adjacent the distal end of the outer shaft. An inner light-delivery element having a distal end and a proximal end is adapted to be operatively connected to the light source. The light-delivery element is configured to be received within the lumen and extend from the proximal end of the shaft to adjacent the distal end of the shaft. The light-delivery element is adapted to deliver light from the light source through the at least one aperture of the outer shaft to the tissue region of the brain in proximity to the distal end of the outer shaft.

A phototherapy device for delivering light emitted by a light source to an infant. The phototherapy device includes two or more light pads configured to be optically connected to a light source via a connector. Light emitted by the light source is received by the connector and propagated through the connector to the light pads. The phototherapy device also includes a flexible garment configured to maintain the position of the pads on a front and back of an infant.

A device for treating the brain includes a light source configured to emit near infrared light. The device also includes a collimator configured to receive the near infrared light emitted by the light emitter. The collimator is further configured to collimate the near infrared light. The device also includes an optic configured to focus collimated light. A reflector of the device is configured to change a direction of the collimated light. The reflector is at a distal end of the device, and the distal end is configured to fit between an upper portion of an eyelid of a patient and an orbital socket of the patient.
