Abstract: A system includes a mask having a filter. The filter is configured to capture aerosol particles. The filter may be formed from a material that is UVC durable and UVC transmissive. The system also includes a UVC LED configured to emit UVC radiation into the filter.

Abstract: A photoreactor for disinfecting water includes at least one wall defining a chamber configured to contain fluid. The reactor also includes an inlet through which water flows into the chamber, and an outlet through which water exits the chamber. The reactor also includes a UVC LED. The LED is configured power on for an active duration, and power off for an inactive duration. The active duration and the inactive duration define a period. The reactor also includes a controller configured to set a duty cycle for the period, where the duty cycle is a ratio of the active duration to the period. The duty cycle is less than or equal to about 1:100.

Abstract: A method of fermenting mycelium composite materials wherein layers of fermentable material are stacked in alteration with ventilation layers with air being passed through the ventilation layers to remove heat and gas generated in the layers of fermentable material during fermentation thereof. The obtained composite materials may be formed into cohesive flat boards, such as are used in the manufacture of insulation or furniture.

Abstract: The mat is formed of a saprophytic fungal strain and/or budding yeast, and a mass of particles wherein the fungus is characterized in producing an enzyme capable of breaking down polycyclic aromatic hydrocarbons. In a second embodiment, a mass of pellets is made from the mat for use in absorbing liquid animal waste.

Abstract: The machine and method employ a moving fluid, either a gas or liquid that is moved through a three-dimensional cavity of a form covered in part with a filter material. The filler material is introduced to the fluid stream and is deposited in the three-dimensional cavity of the form as the moving fluid is filtered from the stream by the filter material.

Abstract: A culture/gelling liquid is formed of a mixture of seed matter and water that is inoculated with a desired cell or tissue strain. The culture/gelling liquid is combined with a substrate in order to be formed into molds, and incubated until a member is formed. The substrate may also be pre-colonized.

Abstract: A sub-atmospheric pressure treatment device may include a chamber, a vacuum source, a pulse sensor, and a controller.

Abstract: The present invention, in one embodiment, includes a reverb device and method for assisting vocalists in hearing their vocal sounds. The reverb device includes a vocal sound receiver, a sound director coupled to the vocal sound receiver and an ear sound deliverer coupled to the sound director. In addition to aiding users in hearing their own voices, the present invention facilitates vocal training, enjoyment and entertainment for users.

Abstract: A wound dressing combining a graduated density felt 1 with an absorbent fiber layer 2 in order that the aggressive absorption of the absorbent layer 2 may be regulated to acceptable rates for wound dressing usage and to ensure potentially irritative alginate absorbent fibers are isolated from the wound site. The graduated density felt 1 acts as a regulating or gate layer for the absorbent fiber layer 2 and so limits the rate that exudate from a wound can pass to the absorbent fiber layer 2. Furthermore, the regulating layer 1 effectively spreads the exudate to give a conical transmission profile enhancing wound dressing performance.
