20090046580 | SYSTEM AND METHOD FOR LOST PACKET RECOVERY WITH CONGESTION AVOIDANCE - Devices and techniques for overcoming lost packets and avoiding congestion when conducting media conferences over packet switched networks are described herein. To avoid the problem of lost packets, redundant information is inserted into the media stream that permits the receiver to reconstruct any lost packets from the redundant information. Congestion avoidance techniques include adjusting the bitrate of the media stream to find the highest bitrate that can be supported without packet loss due to congestion. When increasing the bitrate to a higher rate, the additional bits can come from the redundant information used for lost packet recovery so that any lost packets caused by network congestion will not adversely affect the bitstream. | 02-19-2009 |

20130213264 | METHOD OF PRODUCING HYDRATED LIME - A method of producing a hydrated lime. The process hydrates quicklime in conjunction with standard means of hydrating lime. The resulting hydrated lime has highly reduced contents of calcium oxide and magnesium oxide. The hydrated lime has little to no remaining reactivity when placed in contact with water after the process. The hydrated lime can is with stoichiometric volumes of water as required to fully hydrate the quicklime and water mixture as well as with volumes beyond the calculated stoichiometry with some potential for remaining water left after the process without the potential for lime putty or a wet hydrate as the result. | 08-22-2013 |
20130213275 | METHOD OF FORMING STRUCTURE UTILIZING A HYDRATED LIME MATERIAL - A method of forming structures utilizing a hydrated lime material. A hydrated lime material is formed that is impermeable to water that is formed by subjecting a quicklime to a mixer and adding a surfactant and water to form the hydrated lime. The hydrated lime is then blended with a composite material to form a blended material that is impermeable to water. This blended material is then utilized in differing structures in order to form structures that are impermeable to water. | 08-22-2013 |

20090039968 | DUAL LOOP ARCHITECTURE USEFUL FOR A PROGRAMMABLE CLOCK SOURCE AND CLOCK MULTIPLIER APPLICATIONS - A first phase-locked loop (PLL) circuit includes an input for receiving a timing reference signal from an oscillator, a controllable oscillator circuit supplying an oscillator output signal, and a multi-modulus feedback divider circuit. A second control loop circuit is selectably coupled through a select circuit to supply a digital control value (M) to the multi-modulus feedback divider circuit of the first loop circuit to thereby control the oscillator output signal. While the second control loop is coupled to supply the control value to the feedback divider circuit, the control value is determined according to a detected difference between the oscillator output signal and a reference signal coupled to the second control loop circuit at a divider circuit. While the second control loop circuit is not coupled to control the first PLL circuit, the first PLL circuit receives a digital control value to control a divide ratio of the feedback divider, the digital control value is determined at least in part according to a stored control value stored in nonvolatile storage, the stored control value corresponding to a desired frequency of the oscillator output signal. | 02-12-2009 |

20080210822 | Very high frequency line of sight winglet antenna - A line of sight antenna supported in an upturned terminal winglet or similar vertical member of an aircraft is disclosed. An aperture is formed in the conductive winglet or vertical member, and the antenna is supported within the aperture by a support mechanism such that the antenna is exposed to the line of sight transmissions. A non-conductive covering may also be used for the aperture. Using the cover, the antenna within the winglet can be configured so that it does not alter the appearance or aerodynamic characteristics of the aircraft. Alternatively, the antenna can be coupled to the outside of the winglet or vertical member if cosmetics are not a concern. The frequency range of the antenna can be tuned to cover desired frequency ranges. The antenna position at the winglet maintains a large physical separation from fuselage-mounted antennas thereby reducing interference. | 09-04-2008 |

An individual antenna test enclosure may in one embodiment be provided as an antenna hood having a cavity dimensioned for internally receiving an antenna, such as an aircraft external blade antenna. The cavity of the antenna enclosure may be lined with a RF absorbing material inside the enclosure to allow for RF path testing with substantially no “ringing”, so that accurate phase and gain testing of a received antenna and its RF signal path may be accomplished. | 06-20-2013 |

The easer rail extension is machined to be complementary in shape to the uncut web and fits tightly against the flange, the underside of the head, and the base of the uncut web of the fixed rail. Bolt holes are provided through the extension and the easer rail, its extension, and the fixed rail to form multiple bolt joints. The bolted extension not only lengthens the easer rail but locks it in place between the head and base of the fixed rail to provide additional rigidity. | 01-14-2010 |
