Abstract: Gaseous pollution control devices and methods of removing pollutants from air are described herein. The devices include a body having a first end, a second end opposed to the first end, an upper wall and a lower wall opposed to the upper wall that all co-operate to define a cavity of the body. The device also includes one or more barriers within the body that form one or more channels within the body. At least one barrier has a flow disruptor to disrupt the flow of gas through the one or more channels. The device also includes a light source arranged within the body to direct light into the one or more channels. At least a portion of an inner surface of the device is at least partially coated with a photocatalytic composite material and the light source is configured to illuminate the coated inner surface to activate the photocatalytic composite material to remove the gaseous pollutants.

Abstract: An apparatus for communication between a site within a body deep to the skin and a source, depot, reservoir, device, machine, or power source external to the body via the mouth of the body, comprising an implant for placement in tooth-supporting bone, the implant having a first portion extending into the mouth external to the tooth-supporting bone, a second portion for being embedded in the tooth-supporting bone, and an opening extending along the implant from the first portion to the second portion; and a conduit for coupling to the second portion of the implant when the implant is implanted in the tooth-supporting bone so that the conduit is in communication with the opening, the conduit being for extending from the implant to the site in the body.

A sealing cap containing an antimicrobial substance may be provided to provide a seal when the apparatus is not in use. An external pump may infuse various medications or liquids, including those required by a person having a diabetic condition.
