20110263856 | 8-HYDROXYQUINOLINE-BASED WHITE-LIGHT-EMITTING ORGANIC ELECTROLUMINESCENT MATERIAL - A white-light organic electroluminescent material based on 8-hydroxyquinoline and the method for preparing the same, as well as an organic light emitting diode including this material. The material may be the compound represented by the Formula (IX) having a DCDC group, a 5-position substituted 8-hydroxyquinolinyl group and a carbazolyl group as red light-, green light- and blue-light emitting groups, respectively. It exhibits a spectrum having a band width of 182.4 nm that substantially covers the visible-light region, and has a color coordinate of (0.3177, 0.3946), which just locates within the white-light area. Such a material is capable of realizing a white-light emission, and may be used in a white-light OLED as a single light-emitting layer, which can decrease the number of layers of the white-light OLED and thereby improve the luminous efficiency, stabilize the light color, lower the turn-on voltage and simplify the fabrication process. | 10-27-2011 |

20150162837 | ISOLATED POWER SUPPLY WITH INPUT VOLTAGE MONITOR - A power converter can include an electrical isolation circuit between input and output nodes. An input signal monitor node can be provided, such as on a converter output side of the isolation circuit. In an example, a peak detection circuit can be coupled to the input signal monitor node. The output node of the power converter can be configured to supply an output power signal that is a function of an input signal at the input node. The power converter can include multiple, independently-switchable switches at one or more of the input and output sides of the isolation circuit. In an example, the power converter with the input signal monitor node can be configured as a bias supply to provide power, at the output node, to a controller circuit for a main stage power converter circuit. | 06-11-2015 |

20150308214 | Fold Back Swell Packer - A fold back ring for a swell packer is disclosed. A swell packer has a support member, a swellable element coupled to the support member, and a fold back ring coupled to the support member and engaging the swellable element. The fold back ring is sized and positioned such that when the swellable element swells, the fold back ring flexes outwardly and is caught between the swellable element and the interior surface of the well. The fold back ring therefore forms a barrier against extrusion of the swellable element. | 10-29-2015 |
