| 20100289044 | WAVELENGTH CONVERSION FOR PRODUCING WHITE LIGHT FROM HIGH POWER BLUE LED - A white light LED is described that uses an LED die that emits visible blue light in a wavelength range of about 450-470 nm. A red phosphor or quantum dot material converts some of the blue light to a visible red light having a peak wavelength between about 605-625 nm with a full-width-half-maximum (FWHM) less than 80 nm. A green phosphor or quantum dot material converts some of the blue light to a green light having a FWHM greater than 40 nm, wherein the combination of the blue light, red light, and green light produces a white light providing a color rendering of R | 11-18-2010 |
| 20110084293 | MULTI-GRAIN LUMINESCENT CERAMICS FOR LIGHT EMITTING DEVICES - A ceramic body is disposed in a path of light emitted by a light source. The light source may include a semiconductor structure comprising a light emitting region disposed between an n-type region and a p-type region. The ceramic body includes a plurality of first grains configured to absorb light emitted by the light source and emit light of a different wavelength, and a plurality of second grains. For example, the first grains may be grains of luminescent material and the second grains may be grains of a luminescent material host matrix without activating dopant. | 04-14-2011 |

| 20100006100 | Gel filling for a patient interface and method for producing a patient interface with a gel filling - The invention concerns a gel covering of a patient interface. This gel covering has a mask connection area by which its side that faces away from the patient is joined with a mask body. The patient interface can be designed, for example, as a respiratory mask. On its side that faces the patient's face, the respiratory mask has thin, inwardly formed, peripheral contact lips. The respiratory mask has accessories that allow it to be fastened on the patient's head as well as a hose connection for supplying air. At least one region formed from a filler is placed in or on the walls of the gel covering. The method is used to produce the gel covering of the invention. | 01-14-2010 |
| 20110030701 | Device for preventing leakage from the mouth - The present invention relates to a device for avoiding leakage from the mouth when nasally supplying a respiratory gas on a pressure level lying above ambient pressure. The device comprises a base body made from an elastomeric material and comprises an inner edge portion and an outer ring edge portion, wherein the two ring edge portions are coupled with each other via a web portion, and wherein furthermore the base body, in combination with the two ring edge portions and the web portion, is configured in such a manner that in the application position of the base body the latter defines a lip receiving area for receiving the lips of the user. | 02-10-2011 |
| 20110056498 | FOREHEAD PAD FOR RESPIRATORY MASK - A forehead pad for use in a respiratory mask with a forehead support, which includes a base portion to contact a user's forehead, a support post connected to the base portion, and a head adapted to connect the support post to a forehead support. A pair of forehead pads may be joined with a connector. | 03-10-2011 |
