Abstract: Smoke detectors and smoke alarms are provided which have one or more light shields configured to block or minimize the transmission of ambient light to their light receivers. Light shield configurations for facilitating such functionality are provided as well. The shield/s include a material which attenuates a majority amount of light within a particular range of light that a light source of the smoke detector may be configured to only emit and/or the range of light the light receiver may configured to only convert to photocurrent. In some cases, the shield/s surrounds the light source and/or the light receiver arranged external to an interior chamber of the smoke detector. In some cases, the shield/s may at least partially span a connection side of an external housing of the smoke detector. Alternatively, the shield may be arranged in a space between the interior chamber and the connection side of the housing.

Abstract: Disinfection methods and apparatuses are provided which generate pulses of germicidal light at a frequency greater than 20 Hz and project the pulses of light to surfaces at least 1.0 meter from the disinfection apparatus. The pulses of light comprise a pulse duration and an energy flux sufficient to generate a power flux between approximately 200 W/m2 and approximately 5000 W/m2 of ultraviolet light in the wavelength range between 200 nm and 320 nm at the surfaces. Other disinfection methods and apparatuses are provided which generate pulses of light comprising germicidal light and visible light from a germicidal light source and generate pulses of light from a visible light source that is distinct from the germicidal light source. The projections of visible light from the light sources produce a continuous stream of visible light or a collective stream of visible light pulsed at a frequency greater than 60 Hz.

Abstract: Apparatuses are provided which include one or more germicidal sources, power circuitry coupled to the germicidal source/s, and a shield. The shield and/or at least one of the germicidal source/s are moveable within the apparatus and the apparatus is configured such that the shield and/or the germicidal source/s may be brought in and out of proximity with the other and upon doing so germicide projected from one or more of the germicidal source/s is either substantially contained in the apparatus or is projected exterior to the apparatus for different disinfection modes of the apparatus. The apparatuses include a processor and processor-executable program instructions for activating the power circuitry to operate the at least one germicidal source when the germicidal source is not encased within the apparatus and for activating the power circuitry to operate at least one germicidal source when the germicidal source/s are encased within the apparatus.

Abstract: Methods and systems are provided which project germicidal light from a lamp toward an individual donned in outerwear to disinfect the outerwear. In specific embodiments, germicidal light is projected toward an individual situated greater than approximately 1 foot from the light source. Some systems include sensor/s for detecting presence of an individual within a target area a set distance from the disinfection apparatus comprising the light source and program instructions for commencing operation of the disinfection apparatus based on information from the sensor/s. In addition or alternatively, some systems include reflective panel/s exhibiting greater than approximately 85% reflectance. In such cases, the systems may include program instructions for determining operating parameters of the disinfection apparatus and/or positions of the reflective panel/s based on information regarding an individual who is in the presence of the disinfection apparatus or who is scheduled to be in the presence of the disinfection apparatus.
