Abstract: A sanitizing weighted bracelet with a strap body operably configured to define an enclosure to surround a user's limb, at least one raised section operably configured to house and retain at least one metallic weight, and a sanitizing raised section an upper surface at least partially defining an upper surface of the strap body and defining an access aperture, with a front surface defining an aperture, with a rear surface, and defining at least one channel spatially connected to the access aperture and the aperture defined by the front surface of the sanitizing raised section. The sanitizing raised section also includes a flexible sanitizing container disposed therein and that includes a nozzle projecting outwardly from the aperture of the sanitizing raised section. The flexible sanitizing container is operably configured to be accessible through the access aperture and flexed to cause emission of a sanitizing liquid from a nozzle thereon.

Abstract: A system for extracting polluted air in the vicinity of a road surface, the system comprising at least one inlet assembly arranged to be recessed into the road surface and to be connected to an extraction duct, said at least one inlet assembly comprising: a pod arranged to protrude above the level of the road surface and to be driven over; and one or more intakes located within the pod, the pod defining a passage arranged to be connected to an extraction duct.
