20150219319 | TROFFER-STYLE FIXTURE WITH LED STRIPS - The present invention relates to different embodiments of lighting fixtures, such as troffers. A lens can be placed between a light engine and a reflector and secured in place by crimping portions of the light engine, reflector, or both to prevent the lens from moving. Troffers according to the present invention can lack a dedicated heat sink, instead sufficiently dissipating heat through the light engine. This can significantly reduce the weight of the troffer. Emitter panels can be directly mounted on a light engine inner surface, or on an internal reflector within the light engine. | 08-06-2015 |

20140268730 | LIGHTING FIXTURE WITH BRANCHING HEAT SINK AND THERMAL PATH SEPARATION - The present invention relates to different embodiments of lighting fixtures, such as high bay lighting fixtures, comprising improved features. One of these features can be a driver box placement that is displaced from the center of the fixture. In one such embodiment, the driver box can be mounted such that no portion is over the emitters. Another improved features is a heat sink with branching spokes. As they move away from the center of the heat sink, each of the spokes can branch into multiple spokes, which can improve conductive thermal dissipation. Empty spaces can be left between the spokes to improve convective thermal dissipation. | 09-18-2014 |
20140268750 | LIGHTING FIXTURE WITH REFLECTOR AND TEMPLATE PCB - The present invention relates to different embodiments of lighting fixtures, such as high bay lighting fixtures, comprising one or more improved features. Some of these features include the direct mounting of emitters on a heat sink and/or the use of a template-like board for providing an electrical connection between emitters. These features can improve heat dissipation from the emitters and simplify fabrication. In other embodiments, expensive lens optics of prior art SSL fixtures can be replaced with a flat lens and reflector in order to produce a fixture having a satisfactory spacing criterion. | 09-18-2014 |

20110060226 | FRESNEL-BASED BEAMFORMING FOR ULTRASONIC ARRAYS - An ultrasonic beamformer may include an input signal line for each ultrasonic transducer element configured to carry a broadband pulse from the ultrasonic element. The ultrasonic beamformer may include a number of signal shifters that is substantially less than the number of transducer elements. Each signal shifter may be configured to shift a broadband pulse in a way that is different from the way the other signal shifters are configured to shift a broadband pulse. For each of the input signal lines, a multiplexer may be configured to electrically connect the broadband pulse received on the input signal line to a selected one of the signal shifters. A multiplexer controller may be configured to generate the control signal for each of the multiplexers in a fashion that causes the ultrasonic beamformer to substantially compensate for the differences in the distances. A comparable configuration may be used for transmission. | 03-10-2011 |

20140024945 | ULTRASOUND DEVICE FOR NEEDLE PROCEDURES - A novel ultrasound device for needle procedures is disclosed that comprises a needle with an integrated ultrasound transducer. The transducer may be part of a drop-in, self contained beacon unit that fits within the needle shaft. The transducer may alternatively include electrical leads connectable to an electrical subsystem housed within an adapter that is connectable to a handle. Alternatively, the electrical subsystem may be housed within a handle connectable to the needle by a bayonet-mount configuration, a slide-and-click configuration, or a cartridge configuration. The electrical subsystem is preferably configured to control when the transducer emits an ultrasound pulse. The handle may include all or part of a vacuum means for applying negative pressure to tissue disposed near a tissue sample aperture. | 01-23-2014 |

20120274425 | WIDEBAND ACTIVE QUASI-CIRCULATOR - Aspects describe a wideband active quasi-circulator that has the advantages of small size, lightweight, and compatibility with monolithic microwave integrated circuit (MMIC) technology. An active quasi-circulator is provided that comprises both a power amplifier and a low noise amplifier. The active quasi-circulator can operate over a wide frequency range with isolation or substantial isolation between a power amplifier and a low noise amplifier that is tunable with isolation or substantial isolation at any frequency within the wide frequency range. The provided quasi-circulator is suitable for use in mobile units in multi-band radio frequency communication systems, as well as in other configurations. | 11-01-2012 |
