摘要:
The present invention pertains to a hand-held air sampler device (1) for enrichment of airborne substances and/or particles, in particular microorganisms, comprising: an inlet (2) configured for air intake into a flow channel (3); an outlet (4) configured for fluidically connecting the flow channel (3) to an external vacuum device; a permeable backing element (5) arranged in the flow channel (3), the backing element (5) being configured to receive and support a filter element (6); and a sealing element (7) configured for sealing a filter element (6) received on the backing element (5) such that, when a negative pressure is applied to the outlet (4), air entering the inlet (2) forms an airstream passing the filter element (6) and airborne substances and/or particles, in particular microorganisms, are enriched in the filter element (6). The invention further pertains to an air sampling arrangement comprising: a hand-held air sampler (1) device of this type, a filter magazine (30) for storing and predefined positioning filter elements (6) on a backing element (5) of a hand-held air sampler device (1) of this type and/or a method for applying a filter element (6) to a backing element (5) of a hand-held air sampling device (1) of this type.
摘要:
A photocatalytic reactor housing having a longitudinal axis allowing a fluid to flow through; a frame holding a light source and blades substantially encompassing the light source around the longitudinal axis; each blade having an interior surface facing the light source and an exterior surface opposite the interior surface; at least a portion of the surface of a plurality of the blades having a coating of material with photocatalytic oxidative properties; and the interior surface of the blade configured to redirect some amount of the light emitted onto another portion of substrate of an adjacent blade. In one embodiment the blades are tilted in the radial direction along at least a portion of the blades. In one embodiment the interior surface is configured to reflect some of the light emitted by the light source on to at least a portion of the exterior surface of an adjacent blade.

A lighting device configured to deactivate dangerous pathogens (e.g., MRSA bacteria) in an environment. The lighting device includes at least one lighting element with a single light source configured to provide light. At least a first component of the light comprising light having a wavelength of about 405 nm, and at least a second component of the light comprising light having a wavelength of greater than 420 nm. The first component of light has a minimum integrated irradiance of 0.01 mW/cm2 measured from any unshielded point in the environment that is 1.5 m from any point on any external-most luminous surface of the lighting device.

An ultraviolet (UV) light sanitizing system is configured to sanitize a structure. The UV light sanitizing system includes a UV light assembly that is configured to emit UV light onto the structure, and a UV light emission control unit coupled to the UV light assembly. The UV light emission control unit is configured to control the UV light assembly to emit UV light onto the structure within at least a first UV band and a second UV band that differs from the first UV narrow band during a sanitizing cycle that sanitizes the structure. The UV light within the first and second UV bands is configured to kill at least one type of microbe.
摘要:
An electronic flameless candle including a body having a top surface, a bottom surface, a sidewall between the top surface and the bottom surface, and a cavity defined by the top surface, the bottom surface and the sidewall, the body configured in shape and size to simulate a true flame candle. The candle may also include a light source operably connected to the body, the light source electrically operated to illuminate in a way that simulates a natural flicker of a real candle flame. The candle may also include a scent component, operably connected to the body, the scent component configured to emit a scent when heated and/or a sensor component, operably connected to the body, the sensor component configured to sense an environmental condition and affect a mode of the light source upon the sensing of the environmental condition.

Provided is a sterilization and deodorization apparatus. The sterilization and deodorization apparatus includes a frame defining an outer appearance, a plasma unit disposed on one side of the frame, the plasma unit forming a plasma region to generate a plurality of ions, and a filter unit disposed on the other side of the frame that is spaced apart from the frame unit. The filter unit includes a filter frame having a plurality of through-holes so that air passes therethrough and a photocatalyst applied to the filter frame to perform photocatalytic reaction.
摘要:
Solid fragrance carriers are received in a cavity in between a replaceable shell and a permeable screen of a base that is further housing a heating element, a vertical portion of a ventilation channel and a fan. The solid fragrance carriers are evenly directly aerated by a forced air stream that is evenly heated by passing through the screen positioned around and irradiated by the central heating element. A large storage capacity of the cavity provides for long operation time between refills. Design freedom of the replaceable shell provides for associative shell shapes adaptable to varying themes, characters or consumer goods. The screen and shell may be light permeable for a decorative illumination of the solid fragrance carriers, which may be also color coded for visual scent mixture identification. Conventional liquid fragrance carriers may also be contained in a chalice at the top of the base.
