Publication number: 20080140030Abstract: The present invention is a delivery tip for flowable materials with bristles extending therefrom. The tip is a cannula with a tapered outlet and features a bristle bundle with a binding disk that interfaces with the cannula at some point within the cannula but has a smaller cross-section than the cannula at that point. The bristle bundle then extends out of the tapered outlet. The delivery tip is provided means to connect to a material reservoir with flowable material. When positive pressure is applied to the reservoir, material then will flow through the cannula, around the disk, into the bristles and out the outlet for distribution to a desired surface.Type: ApplicationFiled: May 1, 2007Publication date: June 12, 2008Applicant: CAO GROUP, INC.Inventors: Haiming Zhang, Steven D.

Publication number: 20080118445Abstract: The addition of the Iodide ion by way of iodide salts, such as sodium iodide and potassium iodide, to a peroxide such as hydrogen peroxide in a basic medium yields free radical oxygen and water; generating large amounts of heat and depleting the Hydrogen Peroxide in a matter of minutes. The free radical oxygen generated in this reaction can be utilized to oxidize organic molecules that produce offending stains on select items, including artificial teeth and other dental appliances. Once the free radical oxygen has oxidized the offending molecule the color is lost and the solubility changes allowing any loose fragments of the offending molecule to be washed away in the solvent. The iodide ion catalyzes the reaction allowing for precise control over the speed at which the stain is removed without the need for other expensive, cumbersome energy adding equipment such as lights, lasers, heat sources, etc.Type: ApplicationFiled: January 24, 2008Publication date: May 22, 2008Applicant: CAO GROUP, INC.Inventors: Robert Larsen, Calvin Ostler

Publication number: 20080080184Abstract: The present invention is an LED module for channel letter illumination utilizing multiple through-hole LEDs in a pixel formation as a light source where one surface mounted LED or other forms of LEDs were previously used. The use of a number of small through-hole LEDs ideally requires that a beam angle between and including 15° and 180° in vertical and horizontal directions, respectively, be utilized. When multiple light sources are used on a module, the distance between light sources is to be between 20 mm and 1 cm. The use of several smaller LEDs reduces the current needed to generate light of appropriate intensity and, thus reduces energy cost and heat generation. The use of smaller LEDs also assists in excess heat dissipation.Type: ApplicationFiled: October 3, 2006Publication date: April 3, 2008Applicant: CAO Group Inc.Inventor: Densen Cao

Publication number: 20070287122Abstract: The present invention is a method of treating residual caries utilizing a matched laser and dye combination. After initial preparation and excavation of a caries site, a dye is flooded into the site which stains areas of residual caries. A laser with a complimentary wavelength is then used to ablate stained areas. Since healthy dental tissue will not receive the dye and allow staining, diseased tissue will be the only tissue that is stained, not only providing a visual indicator, but also providing a more efficient surface to receive laser energy and allow for more efficient ablation of the compromised tissue. According to the method, the dye may contain and enhancing, oxidizing compound or an anesthetic, and surrounding tissues may be protected by the use of substances opaque to the radiant energy. Indocyanine green has shown particular effectiveness as a dye in this and related methods.Type: ApplicationFiled: June 7, 2007Publication date: December 13, 2007Applicant: CAO GROUP, INC.Inventor: Steven D.

Publication number: 20070170444Abstract: The present invention is a monolithic, multi-colored LED chip and a method for making the same. The LED chip is comprised of a substrate and a plurality of light emitting structures, each light emitting structure capable of emitting a wavelength of light unique compared to others and each structure layered on top of another structure and separated by a dielectric layer. The light emitting structures are then capable of independent or tandem activation, yielding the original colors of each section, blends of colors, and white light. The method starts with the base for such a chip and etches layers of the chip away, leaving exposed sections, to reach electrical contact layers for each light emitting structure. Electrically conductive material is then used to fill the exposed sections and is, in turn, etched away to leave contacts. An insulating material is then used to fill in the resultant areas.Type: ApplicationFiled: March 21, 2007Publication date: July 26, 2007Applicant: CAO GROUP, INC.Inventor: Densen Cao
