Abstract: A fail-safe tubular receiving member for use in combination with a latch assembly to longitudinally support and rotationally orient the latch assembly in a wellbore. The latch assembly includes at least one outwardly biased, radially movable latch member which is receivable within a bore of the receiving member. A first recessed area and a second recessed area, accessible from the first recessed area, are defined by the bore. The first recessed area defines a first increased radial distance and is configured so that upon longitudinal alignment of the latch member and the first recessed area, the latch member moves radially outward for receipt in the first recessed area to support the latch assembly longitudinally such that longitudinal movement of the latch assembly relative to the receiving member further downhole is prevented. The second recessed area defines a second increased radial distance, greater than the first increased radial distance, and is configured so that upon rotational alignment of the latch member and the second recessed area, the latch member moves radially outward for receipt in the second recessed area to orient the latch assembly rotationally such that rotation of the latch assembly relative to the receiving member is inhibited.

Title: Speech quality measurement in mobile telecommunication networks based on radio link parameters
Inventor: MINDE TOR BJORN
IPC: H04L1/20
Filed: 1998-05-15
Granted: 2007-07-10
Abstract: A method and system for measuring the speech quality in a mobile cellular telecommunications network using available radio link parameters is disclosed herein. In a preferred embodiment, the method includes receiving a set of radio link parameters, as defined in a standard or otherwise available, such as the BER, FER, RxLev, handover statistics, soft information, and speech energy. Temporal information is obtained from the radio link parameters to create a set of temporal parameters which can be statistically analyzed, for example, for the maximum and minimum, mean, standard deviation, and autocorrelation values for a time interval. The temporal parameters are combined to yield a set of correlated parameters that are more closely related to the speech quality. An estimator then uses the correlated parameters to calculate an estimate for the speech quality. The method of the present invention takes advantage of temporal information and correlated relationships from the transmitted parameters. Furthermore, the method is inherently simple and reliable as compared to prior art methods. Still further, the technique provides a method and allows operator to monitor quality conditions throughout the network.

Granted: 2014-10-21
Abstract: The present invention provides a method for selecting proteins with one or more enhanced phenotypic properties of surface expression level, stability, secretion levels and solubility relative to those of a wild-type of said protein. Yeast cells are transformed with a vector expressing a protein to be tested fused to a yeast cell wall protein.  Mutagenesis is used to a generate a variegated population of mutants of the protein to be tested.  The yeast cells are labeled with a first label which associates with yeast expressing the protein having one or more enhanced phenotypic properties of surface expression level, stability, secretion levels and solubility and does not associate with yeast which do not express the protein having enhanced phenotypic properties, and the transformed yeast cells with which the first label is associated are isolated. After analyzing and comparing the phenotypic properties of the mutant protein expressed by yeast with phenotypic properties of the wild-type protein, yeast cells exhibiting proteins with one or more enhanced phenotypic properties of surface expression level, stability, secretion levels and solubility over the wild-type protein are selected.
