Abstract: A full facial host mask is provided that may have a portion that may be removed and re-mated with the host mask. The removable portion may be, for example, a biological mask (e.g., a UV-C device that may include several UV-C light sources (e.g., UV-C LEDs) and such UV-C LEDs may have UV-C reflecting structures arranged to direct UV-Cina particular direction and at a particular size and shape). The UV-C generating device in the removable satellite mask ay be utilized in the breathing stream to provide a low-air resistance, long duration, high performance mask for biological (e.g., DNA-based, RNA-based, gram-positive bacteria, and gram-negative bacteria). The full facial mask may include mechanical filters (e.g., filters having 300 nm pores or smaller), chemical filters, and/or nuclear particulate filters. In doing so, a single mask may be issued to an entity (e.g., a warfighter) that can provide a full facial mask as well as partial face mask so various mission profiles may be achieved.

Abstract: An UV-C device may include several UV-C light sources (e.g., UV-C LEDs) and such UV-C LEDs may have UV-C reflecting structures arranged to direct UV-C in a particular direction and at a particular size and shape. Doing so may, for example, increase the UV-C in a particular direction or working area. A UV-C generating device may be utilized in an air stream, such as an air duct, to sterilize air from that air stream. Multiple UV-C inactivation devices may be coupled in series and placed into a single housing for in order to increase the efficacy of the UV-C inactivation device. The inlet of the device may draw air using an inlet module attachment (e.g., a hood with one or more than one inlet hood) and may output air using an outlet module attachment (e.g., a duct to deliver air to an outflow air duct). Computational fluid dynamic software may be provided where UV-C inactivation devices may be positioned (e.g.

Abstract: A UV-C generator is provided where multiple UV-C LEDs are provided around a work area (e.g., a surface) in order to sterilize contaminants in that work area (e.g., virus and/or bacteria). The sterilization device can be utilized, for example, in a wand, broom, set distance surface sterilizer, hand sanitizer, foot sanitizer, conveyer sanitizer, or any other sanitizer. Mating structures may be included to mate multiple devices to extend work area that may be impacted. The devices may be portable and may include one or more rechargeable batteries.

Abstract: A UV-C generator is provided where multiple UV-C LEDs are provided around a work area (e.g., a tube) in order to sterilize contaminants in that work area (e.g., virus and/or bacteria) to provide a sterilization device for substances in, or flowing through, the work area. The tube may gates to change the speed and/or direction of a flowing working substance and may have a spiraling channel in the tube such that the length of travel in the spiraling channel is longer than the tube. Such UV-C generator devices may be utilized, for example, to sanitize air flowing through devices such as a ventilator or face mask.

Abstract: A hands-free object sanitization system is provided where multiple UV-C LEDs are provided around a work area (e.g., a surface) in order to sterilize contaminants located on objects placed in that work area (e.g., virus and/or bacteria). Objects may travel through the work area without direct human intervention so that a hands-free sanitization system is provided. For example, objects may be dropped through a working area so that gravity provides a transport force through that working area.

A UV-C generating device may be utilized in an air stream, such as an air duct, to sterilize air from that air stream. Sound suppression compartments may be placed around a UV-C generating device inlet and/or a device outlet to reduce sound from the UV-C generating device. Human perceivable (e.g., audible, tactile, and/or visual) notifications may be utilized to provide notification of different modes of operation and/or different efficacy levels (e.g., percent ranges of inactivation of a particular or multiple particular viruses, bacteria, spores, etc.

A UV-C generating device may be utilized in an air stream, such as an air duct, to sterilize air from that air stream. Air may be pushed out of an annulus at the end of an air inactivation device and an annulus outlet cone may be provided in the middle of the annulus to assist, for example, inactivated air in moving smoothly away from the device and reduce pressure at the annulus exit. A UV-C inactivation tube may have UV-C reflective structures at each end to permit air to flow through the tube while reflecting UV-C light back into the tube.

Abstract: A UV-C Amplifier is provided where multiple UV-C LEDs are provided around a work area (e.g., a hollow cylinder) in order to sterilize contaminants in that work area (e.g., virus and/or bacteria) to provide a sterilization device for substances in, or flowing through, the work area. The sterilization device have, for example, mating structures so that the device may be mated with other devices such as, for example, a ventilator or face mask. The sterilization device may be portable and may include one or more rechargeable batteries so that the device can sterilize material flowing into, through, and/or out of one or more devices such as a ventilator or face mask.

Abstract: An air sanitization device is provided where a UV-C generator applied UV-C to infected air for sterilization and then the sterilized air is used to cool heat sinks attached to the UV-C. One or more fans can be utilized to push and/or pull air through the device. For example, the fans may create airflow in the device above, for example 200 liters per minute or above 400 liters per minute. Accordingly, a closed air system with a fan may push air through a UV-C generation device to sanitize air and the sanitized air may be pushed over a heat sink attached to the UV-C generation device and then pushed out of the closed air system into the environment. Thus, sanitized air may be circulated by the fan while being air cooled in a manner that does not circulate contaminated air.
