An excimer bulb assembly including an excimer bulb and a pass filter such that the excimer bulb assembly does not emit substantial UV radiation in wavelengths longer than 231 nm, 232 nm, 233 nm, 234 nm or 235 nm. The wavelengths are measured at an incident angle of zero (0) degrees to the filter plane. The pass filter is preferably constructed of a plurality of layers of hafnium oxide, and most preferably constructed of less than seventy five (75)layers of hafnium oxide. The excimer bulb, pass filter, and two electrical connectors may be adapted to form a cartridge which may be adapted to swivel along its main axis. The cartridge may further include a smart chip. The smart chip may retain and store information regarding the assembly and preferably retains hours of use of the excimer bulb.

The invention relates to automated devices for pro¬ducing aerosols of liquid disinfectants and for spraying same. A mo¬bile hygiene unit comprises a housing (1) containing a disinfectant spraying unit (2) with a spraying nozzle (3), a tank (4) containing disinfectant, a compressor (5), and a control unit (6). It further com¬prises a mechanism for regulating the droplet size distribution of the aerosol, including a pump (7), an electromagnetic valve (8), and a dosing nozzle (9) with an internal cylinder. The disinfectant spraying unit (2) comprises a shaped nozzle (3) having a nozzle head (10) of axisymmetric cross-section attached thereto, and a mixing chamber (11) for mixing disinfectant with compressed air, having two thread¬ed inlets for a pneumatic line (12) and a hydraulic line (13), said inlets being arranged at an angle of 180°. The dosing nozzle (9) contains an internal cylinder and a rod with a threaded tip. The mobile hygiene unit generates an aerosol in four droplet size distribution modes: dry fog (from 3.5 to 10 pm), wet fog (from 10 to 30 pm), mist (from 30 to 50 pm), and spray (from 50 to 100 pm). The invention allows highly precise regulation of the droplet size distribution of the aerosol in each mode without the need to change the spraying nozzle.

A skin care device can include a body including a battery and a grip electrode electrically connected to the battery, and a head connected to one end of the body. The head includes a contact electrode electrically connected to the battery and configured to come in contact with a skin of a user, and at least one ultraviolet light source disposed inside the head to face the contact electrode. Further, the contact electrode includes a fastening part fastened to the head and having at least one hole formed therein to correspond to the at least one ultraviolet light source, and a plurality of contact protrusions protruding from a top surface of the fastening part.

A system for eradicating pathogens is disclosed. A lamp is provided that emits a far-ultraviolet C (far-UVC) light generates an irradiation zone. A biometric sensor determines whether an individual is present in the irradiation zone. The biometric sensor signals a processor to determine whether the individual has been exposed to a threshold limit of far-UVC light. The processor determines whether the time an individual has been in the irradiation zone exceeds a threshold limit. If the individual has been in the irradiation zone a period of time exceeds the threshold, the lamp is deactivated. A pathogen detection sensor provides user feedback of the existence pathogens and signals the processor to terminate irradiation or provide user feedback to terminate irradiation. The system and method are included in a passenger compartment of a vehicle to eradicate pathogens on surfaces and aerosol. Threshold limits allow eradication while the vehicle is occupied.
