Control of halitosis-generating and other microorganisms in the non-dental upper respiratory tract

Disclosed are safe, simple and effective broad-spectrum treatments for halitosis and other microbial infections of the nondental upper respiratory tract useful to treat bacterial and other microorganism species, including anaerobic bacteria. Electromagnetic radiative energy including visible, and optionally, thermal, RF and / or microwave wavelengths, is topically applied to internal surfaces of the upper respiratory tract to destroy or incapacitate superficial microorganisms without the use of antibiotics. One useful apparatus is a handheld energy applicator having a light output head suitable for treating the back of the tongue and the tonsils and which may be interchangeably provided with extensions to reach the sinuses. The energy applicator can be supported and guided by a mounting device held between the subject's teeth, if desired. Useful embodiments of the invention include preparative treatment of the target surfaces with a photosensitizing agent such as an oxidizing agent or a complementary stain. Optionally a pre-treament procedure may be employed to remove detritus and microfloral overgrowths that may mask more deeply resident target microorganisms. Novel treatments include treatment of halitosis by destruction of bacterial species associated with halitosis, such as Atopobium parvulum, by application of non-ionizing radiative energy to the tonsils and the back of the tongue. Another embodiment comprises a candy bar incorporating a halitosis treatment lamp disposed within the candy.

Imaging and display system to aid helicopter landings in brownout conditions

An imaging and display system provides helicopter pilots with an unobstructed display of a landing area in a brownout or whiteout condition by capturing a high resolution image of the landing area prior to obscuration. Using inertial navigation information from the aircraft or an independent system, the system transforms the image to a desired viewpoint and overlays a representation of the helicopter's current position relative to the landing area. The system thus greatly improves orientation and situational awareness, permitting safe and effective operation under zero visibility brownout conditions.

Vascular occlusion systems and methods

A blood vessel occlusion system and method includes a handheld probe including a power source, the probe being adapted to transmit energy from the power source through a body surface and into a target blood vessel, for example a varicose vein. Further included is a manual or automatic switch mechanism adapted to enable and disable the power source in response to a predetermined level of compression applied, by means of the probe against the target blood vessel. When the blood vessel is compressed sufficiently to collapse and substantially slow or substantially prevent a flow of blood therethrough, the power source is activated and the vessel is cauterized, leaving the blood vessel in a condition that is resistant to recanalization.
