A wireless communication unit comprises a transmitter comprising a power amplifier, an inner feedback power control loop having a power control logic module comprising loop priming logic module operably coupled to the power amplifier, and a switchable outer digital loop comprising switchable logic module. The loop priming logic module is arranged to set a power reference value for controlling the power amplifier prior to a ramping operation of the power amplifier and the switchable logic module switching the switchable outer digital loop on or off, thereby restricting adverse transient behavior of the power amplifier.

A control loop has a control slope associated therewith. The control loop is provided to control a unit under control. A method of regulating the control slope comprises the step of measuring the control slope of the control loop and modifying a parameter associated with the unit under control in order to maintain the control slope within a desired range. Lock of the control loop is therefore maintained.

A concentrate dispensing system for dispensing a fluid for dilution, comprises a bracket (1) and a bottle (2). The bracket (1) is arranged to releasably hold the bottle (2). The bottle (2) is arranged to dispense a predetermined quantity of the fluid to a first receptacle type, which is freestanding, when the bottle (2) is in a freehand mode and is not held in the bracket (1). The bottle (2) is arranged to dispense a predetermined quantity of the fluid to a second receptacle type (3), which is received and guided by the bracket (1), when the bottle (2) is in a bracket mode and is held in the bracket (1).

A spinal fixation system comprising at least two bone anchors, a rod connecting the bone anchors and a connecting plate extending from a proximal surface of at least one of the bone anchors. A method of fixing vertebrae relative to each other comprising the steps of: implanting bone anchors in two adjacent vertebrae, each bone anchor having a rod receiving portion; placing a rod in the rod receiving portions, thereby connecting the bone anchors; threadably engaging set screws in the rod receiving portions of at least a portion of the bone anchors, thereby fixing the rod to the bone anchors; mating one end of a connecting plate to a proximal bearing surface of at least a portion of the bone anchors; and engaging a cap with at least a portion of the set screws, thereby fixing the connecting plate to the bone anchors.

摘要:
A method of providing spinal stabilization is provided herein. More specifically, the method includes positioning a plurality of fixation assemblies within a plurality of vertebrae in a trans-lamina orientation wherein each fixation assembly includes a proximal portion configured to securely receive a stabilization element (e.g., a stabilization rod). The proximal portions of the various fixation assemblies can be aligned so as to secure at least one stabilization element in a desired position (e.g., along and above a midline of the patient's spine, adjacent and parallel to the midline). A system for providing spinal stabilization is also provided which utilizes trans-lamina delivery and positioning of fixation assemblies within target vertebrae thereby providing stronger fixation and a significant reduction in associated tissue damage.

A curable method useful for encapsulating solid state devices includes (A) an epoxy resin; (B) an effective amount of a cure catalyst comprising (B1) a first latent cationic cure catalyst comprising a diaryl iodonium hexafluoroantimonate salt; (B2) a second latent cationic cure catalyst comprising (B2a) a diaryl iodonium cation, and (B2b) an anion selected from perchlorate, imidodisulfurylfluoride anion, unsubstituted and substituted (C1-C12)-hydrocarbylsulfonates, (C2-C12)-perfluoroalkanoates, tetrafluoroborate, unsubstituted and substituted tetra-(C1-C12)-hydrocarbylborates, hexafluorophosphate, hexafluoroarsenate, tris(trifluoromethylsulfonyl)methyl anion, bis(trifluoromethylsulfonyl)methyl anion, bis(trifluoromethylsulfuryl)imide anion, and combinations thereof; and (B3) a cure co-catalyst selected from free-radical generating aromatic compounds, peroxy compounds, copper (II) salts of aliphatic carboxylic acids, copper (II) salts of aromatic carboxylic acids, copper (II) acetylacetonate, and combinations thereof; and (C) about 70 to about 95 weight percent of an inorganic filler, based on the total weight of the curable composition. The composition's cure catalyst allows the use of increased filler loadings, which in turn reduces moisture absorption and thermal expansion of the cured composition.
摘要:
Many computing system environments require continuous availability and high operational readiness. The ability to find, diagnose, and correct actual faults and potential faults in these systems is a high priority. By combining a continually updated database of computing system performance with the ability to analyze that information to detect faults and then communicating that fault information to correct the fault or provide appropriate notification of the fault results in achieving the goals of high availability and operational readiness. FIG. (1) shows how the data collectors, fault detectors and policy actions are combined to meet those goals.

The invention provides compounds of the formula (I): or salts, tautomers, solvates and N-oxides thereof; wherein R1 is hydroxy or hydrogen; R2 is hydroxy; methoxy or hydrogen; provided that at least one of R1 and R2 is hydroxy; R3 is selected from hydrogen; halogen; cyano; optionally substituted C1-5 hydrocarbyl and optionally substituted C1-5 hydrocarbyloxy; R4 is selected from hydrogen; a group —(O)n—R7 where n is 0 or 1 and R7 is an optionally substituted acyclic C1-5 hydrocarbyl group or a monocyclic carbocyclic or heterocyclic group having 3 to 7 ring members; halogen; cyano; hydroxy; amino; and optionally substituted mono- or di-C1-5 hydrocarbyl-amino; or R3 and R4 together form a monocyclic carbocyclic or heterocyclic ring of 5 to 7 ring members; and NR5R6 forms an optionally substituted bicyclic heterocyclic group having 8 to 12 ring members of which up to 5 ring members are heteroatoms selected from oxygen, nitrogen and sulphur. The compounds have activity as Hsp90 inhibitors.

A molding composition suitable for encapsulating solid state devices includes an epoxy resin, a hardener, a poly(arylene ether) resin comprising less than 5 weight percent of particles greater than 100 micrometers, and about 70 to about 95 weight percent of a silica filler, based on the total weight of the composition. After curing, the composition exhibits improved increased copper adhesion and reduced shrinkage compared to conventional molding compositions.
