20090295563 | Forward illunination headgear with personal rescue system - The disclosed system provides headgear, i.e., a Firefighter Helmet, with forward illumination that also acts as a personal rescue detection system for quickly finding a downed of lost firefighter. More specifically, the headgear includes a forward illuminating light that has unique characteristics that are easily detected in a smoke filled space by using a handheld photodetector probe that is tuned to the exact characteristics of the light source. The handheld probe has a somewhat narrow directional response to allow a directed search for a downed firefighter or other emergency personnel in a smoke filled noisy environment that hinders normal visual and audible search methods. The handheld photodetector probe produces a unique audio tone that is proportional in volume to the intensity of the exact-characteristics-light-source thus allowing a sweeping motion of the probe to immediately determine the relative direction to a firefighter who is down or requiring assistance. An illuminated visual display also indicates the strength of the unique tone. | 12-03-2009 |

20110179732 | High Rise Building With A Stairwell And A Intake Air Shaft - A high-rise building has a stairwell, an air supply shaft, inlet openings connecting the air supply shaft to the stairwell, and a pressure system for keeping the stairwell free from smoke. The stairwell is vertically divided into several partial spaces. The separation is performed by at least one partition. Each partition has a door enabling a passage from one partial space of the stairwell into an adjacent partial space. | 07-28-2011 |

20090145476 | ISOELECTRONIC SURFACTANT SUPPRESSION OF THREADING DISLOCATIONS IN METAMORPHIC EPITAXIAL LAYERS - A method of reducing propagation of threading dislocations into active areas of an optoelectronic device having a III-V material system includes growing a metamorphic buffer region in the presence of an isoelectronic surfactant. A first buffer layer may be lattice matched to an adjacent substrate and a second buffer layer may be lattice matched to device layers disposed upon the second buffer layer. Moreover, multiple metamorphic buffer layers fabricated in this manner may be used in a single given device allowing multiple layers to have their band gaps and lattice constants independently selected from those of the rest of the device. | 06-11-2009 |
20110011983 | MULTIJUNCTION PHOTOVOLTAIC CELL GROWN ON HIGH-MISCUT-ANGLE SUBSTRATE - The present invention provides a photovoltaic cell comprising a GaInP subcell comprising a disordered group-III sublattice, a Ga(In)As subcell disposed below the GaInP subcell, and a Ge substrate disposed below the Ga(In)As subcell comprising a surface misoriented from a (100) plane by an angle from about 8 degrees to about 40 degrees toward a nearest (111) plane. | 01-20-2011 |
20120313661 | SOLAR CELL TESTING APPARATUS AND METHOD - A solar cell testing apparatus may include an illuminator for directing light energy on a solar cell under test. The solar cell testing apparatus may also include a device for selectively positioning different filters of a multiplicity of filters in an optical path between the illuminator and the solar cell under test to at least one of measure performance and detect any defects in the solar cell. The multiplicity of filters may include a first set of filters and a second set of filters. Each filter of the first set of filters is adapted for passing a predetermined percentage of intensity of the light energy from the illuminator onto the solar cell under test. The second set of filters being adapted for testing the solar cell under different spectrums of light. | 12-13-2012 |
20150083037 | Isoelectronic Surfactant Induced Sublattice Disordering In Optoelectronic Devices - A method of disordering a layer of an optoelectronic device including; growing a plurality of lower layers; introducing an isoelectronic surfactant; growing a layer; allowing the surfactant to desorb; and growing subsequent layers all performed at a low pressure of 25 torr. | 03-26-2015 |

20150054020 | HIGH-POWER ELECTRONIC DEVICES CONTAINING METAL NANOPARTICLE-BASED THERMAL INTERFACE MATERIALS AND RELATED METHODS - High-power electronic components generate significant amounts of heat that must be removed in the course of normal device operations. Certain types of electronic components, such as some monolithic microwave integrated circuits and LEDs, can contain materials that are difficult to effectively bond to a heat gink in order to establish a thermal interface between the two. Device assemblies can include a heat-generating electronic component in thermal communication with a metallic heat sink via a metallic thermal interface layer. The metallic thermal interface layer is disposed between the heat-generating electronic component and the metallic heat sink. The metallic thermal interface layer is formed from a composition including a plurality of metal nanoparticles that are at least partially fused together with one another. Methods for forming a thermal interface layer include heating metal nanoparticles above their fusion temperature and subsequently cooling the liquefied metal nanoparticles to promote bonding of the electronic component. | 02-26-2015 |
