1951 results about "Anti-fog" patented technology

A coating composition is disclosed which comprises an aqueous polymeric matrix, a hydrophilic polymer, a colloidal metal oxide and a crosslinker. The coating composition when applied on medical devices is hydrophilic, shows improved lubricity, abrasion resistance and substrate adhesion on metallic or plastic substrates. The coating also shows improved water sheeting thus providing the coated substrates with anti-fog properties. The coating absorbs aqueous dye or stain solutions making the substrate suitable for printing.

A colored anti-fog mirror that emits reflected light in response to incident light, the colored anti-fog mirror comprising a substrate, a hydrophilic functional layer containing a photocatalytic substance, and a metallic reflecting film provided between the substrate and the hydrophilic functional layer, wherein a material of the metallic reflecting film and a thickness of the hydrophilic functional layer are set such that the reflected light has a spectral reflection spectrum having a maximum reflectance in the visible region over 510 nm and not more than 600 nm.

A flat or curved photochromic laminate structure and a plastic photochromic lens blank can be produced in a simple and efficient manner from relatively low-cost polymeric sheet materials. These laminates can be used to provide goggles, face shields, windows, window coverings, skylights, and optical lenses having efficient, uniform and high quality photochromic properties. The use of a polyesterurethane as the binder for the photochromic material has been found to improve the performance of the photochromic material. There may be a desire to have a protective exterior layer (e.g., an abrasion resistant layer) in combination with the lens system, but that may be provided in various methods. In the case of using the laminate in a goggle application, the laminate may be hard coated on one or both outer surfaces with an abrasion resistant coating, antireflective coating, and / or an anti-fog hard coating.

A sterile, self-contained, disposable apparatus used for heating and applying solution to the distal end of endoscopes as well as an endoscopic lens protector. The heating mechanism is chemical, electrical or a combination of both. Further the apparatus serves as a self sealing container for the storage and application of anti-fog solution. By placing the apparatus over the distal scope prior to surgery, the scope is protected from damage from other instruments or trays. At the same time the distal lens is submerged in the warm anti-fog solution and it is uniformly and completely coated. Heat is transferred to the instrument from the solution in one example to act as an important and additional measure to prevent fogging of the lens. By heating the solution and the instrument, the drastic temperature difference between the interior of the body (98.6) and the instrument is eliminated. This inhibits the condensation of moisture, which always occurs upon inserting the cool scope inside the warm body. The apparatus combines the use of an anti-fog solution as well, which helps prevent fogging during the procedure when smoke and heat is generated within the body during the procedure. Lastly, the apparatus is designed to be used as a holder of the scope while protecting it from impact with a shock absorbent outer shell prior to, during, and after the medical procedure. A new method for defogging endoscopes by which a sterile protective device is combined with a defogging mechanism and placed over the distal lens of endoscopes prior to the medical procedure, used intermittently during the procedure, then placed over the lens at the end of the procedure. The apparatus is not removed until scope reaches the cleaning facility. This apparatus is ideal for sterile operations where the instrument is used intermittently and repeatedly.

Multi-layer coatings are disclosed that include (1) a first layer comprising an inorganic oxide network, and (2) a second layer applied over at least a portion of the first layer, wherein the second layer is deposited from at least one liquid composition that is hydrophilic and includes an essentially completely hydrolyzed organosilicate. Also disclosed are substrates coated with such multi-layer coatings, methods of applying such multi-layer coatings to a substrate and methods for improving the anti-fouling, self-cleaning, easy-to-clean, and / or anti-fogging properties of an article.

A variety of refrigerators and merchandisers having glass or plastic substrates that are substantially fog-resistant are provided. For example, refrigerator doors having a substantially transparent substrate including an anti-fog coating on at least a portion thereof are provided. The portion of the substrate may substantially not fog when the portion has an initial surface temperature and is then exposed to a moist air ambient with a dewpoint temperature equal to or greater than the surface temperature for a period of time. The surface temperature may be less than about 0° C. and the period of time may be greater than about 6 seconds.

A device is configured for white balancing a medical videoscopic camera system prior to videoscopic medical procedures, as well as optionally simultaneously or non-simultaneously applying a fog-prohibiting agent to the distal lens of a medical videoscope such as an endoscope or laparoscope. The device combines a white balancing mechanism, protective mechanism, and defogging mechanism in one simple easy to use device.

A variety of refrigerators and merchandisers having glass or plastic substrates that are substantially fog-resistant are provided. For example, refrigerator doors having a substantially transparent substrate including an anti-fog coating on at least a portion thereof are provided. Many of the coatings exhibit color stable properties.

A coating composition that is incorporated into a facemask to reduce fogging and glare is provided. For example, in one embodiment, the facemask contains a shield or visor formed from a transparent substrate having at least one surface applied with the coating composition of the present invention. The present inventors have unexpectedly discovered that one or more water-soluble organic polymers, such as ethyl hydroxyethylcellulose, may be utilized as a principal component of the coating composition to reduce fogging and glare in a simple, yet effective manner.
