20110037906 | LOW FREQUENCY ENCLOSURE FOR VIDEO DISPLAY DEVICES - A television includes a flat panel display device for presenting video images, a housing for supporting the flat panel display device, and a first acoustic volume located substantially (a) inside the housing, and (b) behind the display device. Two or more acoustic drivers are provided for acoustically energizing the acoustic volume. The drivers are positioned such that acoustic energy put into the acoustic volume from the drivers is substantially additive and vibrational energy from the drivers substantially cancels out. | 02-17-2011 |
20110235824 | System and Method for Excursion Limiting - The present disclosure generally relates to a system for limiting the excursion of an audio speaker. The system may include first lowpass filter circuitry configured to receive a system input signal and to generate a first signal. The system may further include clipping circuitry configured between the first lowpass filter circuitry and the first combiner circuitry. The system may include first highpass filter circuitry configured to receive the system input signal and to generate a second signal. The system may include second lowpass filter circuitry configured to receive a combined output signal from the first combiner circuitry. The system may include allpass filter circuitry configured to receive the system input signal and to generate a fourth signal. The system may include second highpass filter circuitry configured to receive the fourth signal from the allpass filter circuitry. The second combiner circuitry may be configured to generate an excursion limiting output signal. | 09-29-2011 |

20140049956 | LIGHTING APPLICATIONS USING ORGANIC LIGHT EMITTING DIODES - A lighting device that includes a first panel of light sources, where the first panel has a first edge. The lighting device can also include a second panel of light sources, where the second panel has a second edge, where the second edge of the second panel of light sources is mechanically coupled to the first edge of the first panel of light sources. The first panel of light sources and the second panel of light sources can form an angle relative to each other. Adjusting the angle can adjust the light output from the light sources. Such an angle can be formed based on a target level of light received by a target area. | 02-20-2014 |

20120201482 | REMOVABLY ATTACHABLE STORAGE DEVICE - A temporary storage device fabricated at least in part of memory stretch material (such as synthetic rubber, e.g. polychloroprene material and the like. A storage portion of said device may be fabricated from the same polychloroprene material and is configured with at least one defined storage pocket. An attachment portion of the storage device has defined therein at least one generally annular stretchable opening. This attachment opening, due to the elastically stretchable quality of the device fabric will be stretched sufficiently to surround and cling snugly to a support stanchion such as a bedpost commonly found on a bunk or loft bed. More than one attachment opening of different sizes can be defined in the attachment portion so as to sizably correspond with different posts. The suspended storage device remains in place due to its gripping elasticity as well as gravity pull which distorts and further tightens the elastic opening. | 08-09-2012 |

20110187577 | Resolution Radar Using Metamaterials - A radar system includes at least one transmit array comprising a plurality of metamaterial elements. The radar system further includes at least one near-field stimulator for inputting electromagnetic signal to the transmit array so that a sub-wavelength target is illuminated with an electromagnetic wave. | 08-04-2011 |
20140253409 | COMPOSITES FOR ANTENNAS AND OTHER APPLICATIONS - Composite material, devices incorporating the composite material and methods of forming the composite material are provided. The composite material includes interstitial material that has at least one of a select relative permittivity property value and a select relative permeability property value. The composite material further includes inclusion material within the interstitial material. The inclusion material has at least one of a select relative permeability property value and a select relative permittivity property value. The select relative permeability and permittivity property values of the interstitial and the inclusion materials are selected so that the effective intrinsic impedance of the interstitial and the inclusion material match the intrinsic impedance of air. Devices made from the composite include metamaterial and/or metamaterial-inspired (e.g. near-field LC-type parasitic) substrates and/or lenses, front-end protection, stealth absorbers, filters and mixers. Beyond the intrinsic, applications include miniature antenna and antenna arrays, directed energy weapons, EMI filters, RF and optical circuit components, among others. | 09-11-2014 |

20100007561 | BROADBAND PATCH ANTENNA AND ANTENNA SYSTEM - A patch antenna includes a ground plane on a surface of a substrate. Patch radiators are formed on another surface of the substrate. Each patch radiator includes tuning slots extending from an edge of the patch radiator toward an interior section such that the slot is separate from a feed point of the patch radiator. In some embodiments, the patch antenna includes a feed-through conductor disposed through the ground plane and substrate and coupled to the patch radiator. In some embodiments the patch antenna with the feed-through conductor is a razor patch antenna. An antenna system includes a patch antenna and a transceiver board, which includes a substrate and a ground plane on the substrate. A second feed-through conductor runs through the ground plane and transceiver substrate to connect to a transceiver device. The transceiver board and patch antenna are abutted such that the first and second feed-through conductors connect. | 01-14-2010 |
