A laser hat with an adjustable fit is provided, which includes a hat body, a plurality of laser modules, a flexible printed circuit board and an adjustment mechanism. The hat body is made of a honeycomb structure. A woven mesh can be used on an inner layer of the hat body. The plurality of laser modules are disposed on the flexible printed circuit board. The flexible printed circuit board is disposed in the hat body and drives the plurality of laser modules, which are used to irradiate a user's head to stimulate hair follicles, and can also be used for laser acupuncture and laser health care treatments for the head. The adjustment mechanism is disposed on one side of the hat body that can be used to adjust a hat fit.

A device in the form of a cap, for generating an isolation barrier for airborne pathogens between the wearer's face and the environment. A major part of the outer surface comprises filter material, allowing filtered air to flow from the environment into a chamber beneath the surface layer. A fan sucks air through the filter element and into the chamber. A horizontally oriented slot is situated across the visor portion of the cap structure, in front of the forehead of the person when the device is worn by the person. The slot has a width substantially smaller than the length. The flow of filtered air within the chamber is directed out of the slot as a curtain-like flow of filtered air in front of the face of the person. A cross-flow fan mounted just above the slot is most effective in generating the curtain flow.

Interactive therapeutic devices for wear on a head of a user are provided herein, along with kits including the interactive therapeutic device and an activity book, and methods of using the devices and kits. Contemplated devices comprise a set of attachment points that removably couple with a set of patches via fastener components. The patches can include various types of patches that provide different benefits to the wearer, including style, a scent, a noise, a tactile sensation, protection, and/or the ability to better communicate a feeling and/or a need.

A personal sterilization system, including a base unit defining an air intake, a fan, and a fluid path from the air intake to the fan; at least one UVC light source positioned to illuminate at least a portion of the fluid path with UVC light; a delivery conduit attached to the base unit in fluid communication with the fan; and a dispersion device configured to be worn in proximity to a person's face, the dispersion device defining a fluid inlet attached to the delivery conduit, and at least one fluid outlet configured to disperse pressurized air.

A headset device is described herein comprising a lower band comprising an outer surface and an inner surface, wherein a front portion of the lower band comprises at least one sensor positioned on the inner surface, wherein at least one arm extends from the lower band, wherein a proximal end of the at least one arm is rotatably attached to the lower band, wherein a distal end of the at least one arm comprises a sensor, wherein a rear portion of the lower band comprises adjustable straps for adjusting a circumference of the lower band. The headset device comprises an upper band comprising an upper surface and a lower surface, wherein at least one dry electrode component extends from the lower surface of the upper band, wherein the upper band is adjustably attached to the lower band.

Embodiments of particle protection headwear apparatuses and use thereof are detailed herein. In general, embodiments of the present invention include a shield and a shroud which couple to, or are partially or wholly integral with, a hat. The shield extends downwardly from the hat and is typically embodied as part of the hat. Further, the shield is designed for a user to be able to look through it. The shroud is coupled to and extends downwardly from the shield and the hat. The shroud extends entirely around a perimeter of the hat to form a breathable barrier between particles and the user's head. The shroud may be removeable from the shield and washable.
