Abstract: An apparatus for inactivating bioaerosol, comprising an enclosure having lumen walls forming a lumen, said lumen having a lumen input opening and a lumen output opening; a ventilator arranged for forcing an air flow through said lumen; in a cleaning section of said lumen, a source of ultraviolet light arranged to irradiate with ultraviolet light all the air passing through said lumen along a length of said cleaning section; an output muffler arranged for reducing a noise of said air flow in output of said lumen output opening; and a downstream turn section of said lumen, downstream said cleaning section of said lumen, arranged for changing a direction of said air flow such that no ultraviolet light in said cleaning section of said lumen is detectable at said lumen output opening.

Abstract: A hybrid power supply for a high intensity light includes a power supply coupled to the high intensity light, wherein the power supply has a power rating less than a power rating for the high intensity light, and a battery, the battery having a power rating greater than or equal to the power rating for the high intensity light. A switch is coupled between the high intensity light and the battery, such that when the switch is closed the battery is coupled to the high intensity light, and such that when the switch is open the battery is not coupled to the high intensity light.

Abstract: A vehicle testing lamp system comprising an onboard controller unit, an off-board controller unit, and a lamp fixture. The onboard controller unit comprises a solid state relay, the solid state relay being switchable between an idle output power setting and a high output power setting; a timing circuit,; a transfer circuit; a current sensor; a current regulator; and batteries or other auxiliary power supply. The off-board controller unit comprises a power supply electrically connected to a voltage booster circuit. The lamp fixture comprises an ignitor; a shock mount; and a lamp that is electrically connected to the igniter. The off-board controller supplies power to the lamp at its idle level. The onboard transfer circuit permits the off-board power supply to be disconnected while the onboard controller unit maintains the lamp at idle, and the onboard timing circuit limits the time that the lamp remains at high output. Also disclosed is a method for using a vehicle testing lamp system.
