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.

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.

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.

The invention relates to an integrated camera visual vacuum suction device, which comprises a double-cavity suction tube, wherein a vacuum suction cavity and a lateral cavity are arranged inside the double-cavity suction tube; the head end of the vacuum suction cavity is provided with a vacuum suction opening; a signal wire is arranged in the lateral cavity; the head end of the lateral cavity is connected with a miniature camera; the signal wire is connected with the miniature camera; the front end of the miniature camera is provided with an eclosion lens; the front end of the miniature camera is also provided with an LED (light emitting diode) patch lamp; the tail part of the double-cavity suction tube is provided with a handle; the tail end of the double-cavity suction tube is provided with a negative pressure connecting head; the tail end of the signal wire is connected with a video connector; the video connector is arranged at the tail end of the handle. The integrated camera visual vacuum suction device has the advantages that the structure is reasonable; the operation is fast; light weight and flexibility are realized; the success rate is high; the safety is high; the work intensity of physicians is effectively reduced; the injury on human body tissues is reduced.

The invention relates to the technical field of steel-making automation, in particular to a method for preventing a converter from doumping steel. Through the control of a PLC, the steel dumping prevention is realized by carrying out corresponding blocking on the gear positions of second, third and fourth gears of a dumping controller of the converter, a numerical controller enabling and switching-off ports; when a system carries out the sampling and slagging of a rocking furnace in front of the converter or when an angle goes to steel tapping area behind the converter, the enabling signals ofthe dumping second, third and fourth gears are blocked from transmitting to the numerical controller, so that the converters in the two areas only can work at first-gear speed, no matter which gearsthe controller is set at; during sampling in front of the converter or tapping steel behind the converter, when reaching a certain angle point in a heavy state, the converter is prevented form turningdown. The invention has the advantages that the technology can control steel making operation completely, automatically realize safe linkage of converter rotating, turning down and tapping, achieve asafe and effective automatic operation, and avoid production accidents caused by steel-making disoperation, instead of equipment faults.

The invention relates to medical apparatus, especially relates to a multi-functional automatic moderation device for transfusion, comprising medicine preparation device, air exhauster and air passage conversion device; and said medicine preparation device comprises medical agent bottle, transfusion bottle, air conduit and long needle head. The two ends of liquid conduit are connected with needle head, and they are inserted into medical agent bottle and transfusion bottle to form liquid circuit. The air exhauster comprises air pump and air conduit, and the air passage conversion device is equipped with air conversion valve, valve core automatic driving device. The air passage conversion is also provided with air vent interface A, B, C, D, A is connected to air, C is connected with air exhauster, B and D are connected to medical agent bottle and transfusion bottle of medicine preparation device through air conduit and short needle head, respectively. When control valve core is connected with B, C, A and D, the liquid is transported to medical agent bottle from transfusion bottle, and when valve core is connected to A and B, C and D, the liquid refluxes from medical agent bottle to transfusion bottle. The invention is characterized buy simple operation, high efficient medicine preparation and no pollution.

A bicycle seat design that comprises appropriately spaced and configured depressions that conform to the body of variously-sized male riders, thereby reducing pressure normally present on the lumbar back region, the ischial buttocks regions, and groin. Superior safety features provide comfort and support to vulnerable parts of the body. The preferred embodiment contains a round seating platform with raised rear and lateral edges and a left and right depression shaped to accommodate and support the buttocks. It also contains a depression in the central front area of the seating platform suitably shaped to accommodate and support the scrotal region, for preventing damage commonly associated with jarring or snagging the scrotum. Optionally, turning-signals, brake lights, and reflective lights positioned on the rear portion of the seating platform are included for enhancing visibility of the bicycle and for promoting safe operation thereof.
