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.

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.

A phototherapy shield for an infant includes a shield body that is sized and shaped to extend around at least a portion of a torso of an infant. The shield body includes a reflective foil layer that is sandwiched between an upper fabric layer and a lower fabric layer and that is configured to block phototherapy light. A fastener is attached to the shield body to secure the phototherapy shield around the infant's torso. The disclosed phototherapy shield and associated methods are useful for shielding an infant undergoing phototherapy, and more particularly, for shielding the chest of a premature infant undergoing phototherapy to treat jaundice. The shield body can be sized and shaped to cover the infant's chest over the second to fourth thoracic rib position to shield an area of skin above a patent ductus arteriosus (PDA).

A photodynamic therapy apparatus for local targeting in cancer treatment capable of treating various types of cancers or tumors. An endoscope is placed in the center of an end portion of a probe used in photodynamic therapy and a plurality of optical fibers are arranged along the edge thereof, so that a lesion site is irradiated with a plurality of lights while the plurality of optical fibers of the probe receive lights from individual light sources, respectively, to perform light irradiation individually. An apparatus is disclosed, wherein unnecessary damage to normal tissues is minimized by controlling light irradiation regions, for instance, by defining light irradiation regions encompassing a lesion site from an image provided in real time through an endoscope disposed at an end portion of a probe and allowing only individual light sources irradiating the defined light irradiation regions to emit lights to achieve local light irradiation.

A home phototherapy system for producing vitamin D via skin exposure and associated methods are disclosed herein. In some embodiments, the system includes a UV-emitting device that includes a housing and a UV light assembly carried by the housing. The UV light assembly can include an array of UVB light emitters and an optical component that, together, emit phototherapeutic UV radiation from an active side of the housing to promote vitamin D production in skin (e.g., a human torso) exposed to the UVB light. The system also includes a dose controller operably coupled to the UV light assembly that can create a dosing protocol for the UV light assembly and specific to the user. The dose controller can be implemented on an application in a mobile device, within the UV-emitting device, and/or a cloud server.
