20100129994 | Method for forming a film on a substrate - A method for forming a film on a substrate comprising: heating a solid organosilane source in a heating chamber to form a gaseous precursor; transferring the gaseous precursor to a deposition chamber; and reacting the gaseous precursor using an energy source to form the film on the substrate. The film comprises Si and C, and optionally comprises other elements such as N, O, F, B, P, or a combination thereof. | 05-27-2010 |
20110146787 | SILICON CARBIDE-BASED ANTIREFLECTIVE COATING - The present invention relates to an antireflective coating comprising an amorphous silicon carbide-based film, which film further comprises hydrogen atoms and optionally further comprises oxygen and/or nitrogen, the film having an effective refractive index (n) between 2.3 and 2.7 and an extinction coefficient (k) of less than 0.01 at a wavelength of 630 nm. The present invention also relates to methods for preparing the antireflective coating and to solar cells comprising the antireflective coating. | 06-23-2011 |

20130335270 | COMPRESSIVE BEAMFORMING - A method of antenna array processing. Digitized time-series data from a plurality of antenna elements are divided into a plurality of time windows. A Fourier Transform is performed on a time window of the plurality of time windows for each antenna element of the plurality of antenna elements to generate a plurality of frequency domain vectors. The plurality of antenna elements is divided into a plurality of largest aperture sub-arrays. The frequency domain vectors are compressive beamformed for the each sub-array to generate a plurality of bearing estimates corresponding to the plurality of sub-arrays. The plurality of bearing estimates from the plurality of sub-arrays are sparsely combined to generate a plurality of frequency-specific bearing estimates. The plurality of frequency-specific bearing estimates are incoherently averaged over a range of frequencies to generate a bearing for a bearing-timing record. A plurality of bearings for the bearing-timing record is generated. | 12-19-2013 |

20090250063 | HYPERBARIC/HYPOXIC CHAMBER SYSTEM - A portable chamber for hyperbaric/hypoxic treatment comprises a tubular body sized so as to accommodate an occupant. The tubular body is made of a non-rigid material. End frames are secured to opposed ends of the tubular body to close off the tubular body. One end frame has a door displaceable from a remainder of the end frame to provide/close access to an interior of the tubular body. Longitudinal beam members are connected at opposed ends to the end frames so as to maintain the tubular body in a taut condition between the end frames, whereby the portable chamber is in fluid communication with a pressure generator so as to receive an air supply from the pressure generator to increase a pressure in the interior of the tubular body for hyperbaric treatment. | 10-08-2009 |
20130206146 | Portable Chamber for Hyperbaric and/or Hypoxic Treatment - A portable chamber for hyperbaric and/or hypoxic treatment comprises an open-ended and typically frustro-conical tubular body sized to accommodate at least one occupant, and two end members configured to be respectively received at opposite extremities of the body for closing the body in a seal tight arrangement. The body of the chamber is made of a flexible yet reinforced elastomeric material such as to be collapsible during transport. One of the end members is provided with a door to provide access to the interior of the chamber. The extremities of the body are substantially spherical such as to receive the correspondingly substantially periphery of the end members. When the chamber is supplied with gases during hyperbaric or hypoxic treatment, the spherical peripheries of the end members are urged against the spherical extremities of the body, thereby providing a seal tight chamber. A treatment system comprising the chamber is also disclosed. | 08-15-2013 |
