摘要： An air disinfection device includes a shell having entry and exhaust ports, a power supply installed above the shell, and a dust collecting cylinder installed on the shell, connected to a negative electrode of the power supply, and having air inlet and outlet. The air inlet and the air outlet are communicated with the entry port and the exhaust port, respectively. The conductive rod has one end installed above the shell and connected to a positive electrode of the power supply, and the other end located in the dust collecting cylinder and close to the air inlet. An arrangement direction of the conductive rod is consistent with an axis direction of the dust collecting cylinder. The power supply provides high-voltage current to the conductive rod to form a symmetrically distributed high-voltage electrostatic field inside the dust collecting cylinder to sterilize and disinfect air passing through the dust collecting cylinder.

摘要： Methods and systems are provided for heat sanitizing a vehicle. In one example, a method may include, responsive to receiving a request for cleaning an interior of a vehicle, adjusting a position of a sun shade based on at least one of an ambient temperature outside of the vehicle and a sun load of the vehicle, and operating a heating, ventilation, and air-conditioning (HVAC) system to heat the interior above an upper threshold temperature for a first threshold duration. In this way, the HVAC system may be advantageously used to expose the vehicle interior to temperatures that kill or inactive microbes.

摘要： Sanitizing devices may be configured to emit sanitizing light into an environment in order to sanitize air, objects, and/or surfaces in the environment. The sanitizing light may be of a wavelength, or set of wavelengths, that deactivates, kills, or neutralizes, pathogens such as bacteria and viruses but, is not harmful to human or animal tissue. The sanitizing devices may be configured to be able to communicate with each other and/or a user over, for example, the Internet, a wireless communication network, a mesh network, and/or a near-field communication protocol in order to, for example, provide operation information and/or receive operation instructions.

摘要： A system and method for sterilizing recirculated airflow in closed environments, as well as certain types of material equipment includes electronically steered antenna (ESA) elements. The ESA elements operate in radio frequencies (RF). The ESA elements produce directed beams of microwave radiation to sterilize surfaces or volumes of air. The directivity gain associated with the beam forming increases RF energy density in the area where the beam is steered.

摘要： An apparatus used to disinfect viruses/bacteria contaminated exhaust air from devices, such as ventilators, CPAP, APAP, VPAP auto, BiPAO, ECMO, and also devices for air filtration used in cars, buildings, ships, planes, etc. is disclosed in this document. A heat source is used to burn the contaminated air at elevated temperatures, such as 100° C., 500° C., 1,000° C., and/or even more, in a confined environment to inactivate/destroy viruses/bacteria carried in the air. The heat sources can be, but not limited to, electrical, gases, infrared, microwave, and Ultraviolet (UV). After disinfection, the exhaust air from the apparatus is then released to the ambient environment, or to the next chamber for further treatment.

摘要： An ultraviolet emitting system for sanitizing a target volume can include a plurality of adjustably positionable light sources having a collapsed position and the expanded position. The light sources of the plurality of adjustably positionable light sources can be configured to emit ultraviolet light in a substantially homogenous irradiance within the target volume in any position between the collapsed position and the expanded position.
