20100058879 | MATERIAL WITHDRAWAL APPARATUS AND METHODS OF REGULATING MATERIAL INVENTORY IN ONE OR MORE UNITS - Material withdrawal apparatus and methods and systems of regulating material inventory in one or more units are provided. A material withdrawal apparatus includes a heat exchanger and a sensor. The heat exchanger includes a material inlet, material outlet, cooling fluid inlet, and cooling fluid outlet. The material inlet is coupled to the unit and the sensor is coupled to the heat exchanger to provide a metric indicative of the temperature at the material inlet; material outlet; cooling fluid inlet and cooling fluid outlet. Another embodiment of a material withdrawal apparatus includes a vessel having an outer wall, liner, fill port, and a discharge port. The liner at least partially covers the inner surface of the outer wall. The fill port and discharge port are defined in the vessel and the fill port is configured to receive withdrawn material from at least a unit. Other embodiments provide methods of withdrawing or regulating material in a unit. | 03-11-2010 |

20150026309 | SYSTEMS AND METHODS FOR ADAPTIVE STREAMING CONTROL - Systems and methods for adaptive streaming control include a network, a network device, and a plurality of media clients served by the network. The network device monitors media session conditions for a media session with a media client served by the network and enforces policy on the media session based on the media session conditions. The network device can enforce policy by determining a current estimated media quality of the media session based on the monitored media session conditions, determining a target media quality for the media session, and modifying the media session responsive to a difference between the current estimated media quality and the target media quality exceeding a threshold. | 01-22-2015 |
20150163273 | MEDIA BIT RATE ESTIMATION BASED ON SEGMENT PLAYBACK DURATION AND SEGMENT DATA LENGTH - A device includes an interface to a media session comprising transmission of a stream of one or more media segments having unparseable media containers. The device further includes a bit rate estimation module coupled to the interface, the bit rate estimation module to estimate a bit rate for the media session based on a ratio of a first metric to a second metric, the first metric representing a sum of data lengths of the one or more media segments in the media session and the second metric representing a sum of playback durations of the one or more media segments. | 06-11-2015 |

20160069737 | Weighing Scales - Scales include at least one transducer, a weighing pan arranged such that weight applied to the weighing pan is referred to the transducer, and electronics which receive an output from the transducer and drive a display to provide a user with a visible indication of the weight applied to the weighing pan. The transducer and electronics are contained in a sealed enclosure defined at least in part by a flexible water-tight membrane which is able to move and thereby (a) to accommodate changes of volume of the sealed enclosure without creating a pressure differential between the interior and the exterior of the sealed enclosure and (b) to accommodate movement of the weighing pan. The water-tight membrane may include a double film comprising a saturated salt solution between two films. | 03-10-2016 |

20090007284 | TRANSGENIC ORGANISM - A method of producing a transgenic cell comprising introducing into a cell a non-primate lentiviral expression vector comprising a nucleotide of interest (NOI). Also described is a method of producing a transgenic cell comprising introducing into a cell a lentiviral expression vector comprising a NOI capable of generating an antisense oligonucleotide, a ribozyme, an siRNA, a short hairpin RNA, a micro-RNA or a group 1 intron. Also described is a viral vector comprising a first nucleotide sequence, wherein said first nucleotide sequence comprises: (a) a second nucleotide sequence comprising an aptazyme; and (b) a third nucleotide sequence capable of generating a polynucleotide; wherein (a) and (b) are operably linked and wherein the aptazyme is activatable to cleave a transcript of the first nucleotide sequence such that said polynucleotide is generated. | 01-01-2009 |
