摘要:
A cooling mechanism is provided for an audio speaker, which mechanism includes a plate of a thermally conductive material mounted between the driver mechanism of the speaker and the speaker basket and extending from the voice coil gap to the outside of the speaker. The spacing between this plate and the voice coil is preferably kept as small as possible. The plate is preferably a vent plate having a plurality of radial vents extending along the width of the plate from the voice coil gap side thereof to the side facing the outside of the speaker. Such a vent plate, in addition to providing radiant cooling, also provides cooling via air flow as well as conduction and convection cooling. The vents are sized and shaped so as to minimize any turbulence, and thus any audible air noise.

An audio speaker contains a tweeter capable of continuous rotation, where the audio speaker contains the tweeter and an axis mount assembly. The tweeter is removably connected to the axis mount assembly. The audio speaker also contains a first connection member capable of maintaining electrical communication with the axis mount assembly throughout continuous rotation of the axis mount assembly. The axis mount assembly contains a terminal plate connected to a bottom portion of the tweeter, where the terminal plate maintains electrical communication with the tweeter. The axis mount assembly also contains an axis mount faceplate capable of receiving the terminal plate and tweeter within an indented portion of a top portion of the axis mount faceplate. The axis mount assembly further contains an axis mount spacer and a second connection member that maintains electrical communication with the first connection member throughout continuous rotation of the axis mount assembly.

摘要:
A technique includes using a computer agent to observe diagnoses of computer-related incidents. Based on the observation, patterns are identified in the diagnoses, and based at least in part on the patterns, the diagnoses are selectively automated.

The present invention concerns a compound of formula (I) or a pharmaceutically acceptable salt or solvate thereof, where R1-R3 and Y are defined in the description, and its use in the treatment of disorders in which pi3 kinase is implicated.
摘要:
There are provided according to the invention compounds of formula (I), in free or salt form, wherein R1, R2, R3, R4, R5, R6, Q, W, X, m, n and p are as described in the specification, process for preparing them, and their use as pharmaceuticals.
摘要:
The tent frame includes an upper hub with a plurality of ribs intended to extend outwardly and a lower hub having an equal number of stretchers. The ends of the stretchers are pivotally connected to the ribs. As the lower hub moves upwardly, the stretchers force the ribs outwardly to erect the tent. Flexible cords extend down from the upper hub through the lower hub and out apertures in the bottom of the lower hub. Pulling the cords apart from within the tent causes the lower hub to move upwardly toward the upper hub to erect the tent. Alternatively, the cords can be passed around pulleys in the lower hub and upwardly through apertures in the top of the upper hub. Pulling the cords apart from above the tent causes the lower hub to move upwardly toward the upper hub to erect the tent.

A compound of formula (I) or stereoisomers or pharmaceutically acceptable salts thereof, and their preparation and use as pharmaceuticals wherein R1, R2 and R3 are as defined herein.
摘要:
Compounds of formula (I) in free or pharmaceutically acceptable salt form, where R1, R2, R3, R4, R5, R6, R7, m, n, w, X, and Y have the meanings as indicated in the specification, are useful for treating conditions mediated by the CRTh2 receptor, especially inflammatory or obstructive airways diseases.
摘要:
The present invention concerns a compound of formula Ia wherein: Ra* is hydrogen or C1-4-alkyl; Rb* is —(C1-C4-alkylene)-Y—C1-4-haloalkyl or —(C1-C4-alkylene)-Y—C1-C4-hydroxyalkyl; Y represents —CONH— or a five membered heteroaryl group. R2* is C1-C4-alkyl or halogen; R3* is halo, —SO2—CH3, —SO2—CF3, carboxy, —CO—NH2, —CO-di(C1-C8-alkyl)amino, or a 5- or 6-membered heterocyclic ring having one or more ring hetero atoms selected from the group consisting of oxygen, nitrogen and sulphur, that ring being optionally substituted by halo, cyano, oxo, hydroxy, carboxy, nitro, C3-C8-cycloalkyl, C1-C8-alkylcarbonyl, C1-C8-alkoxy optionally substituted by aminocarbonyl, or C1-C8-alkyl optionally substituted by hydroxy, C1-C8-alkoxy, C1-C8-alkylamino or di(C1-C8-alkyl)amino; R4* is hydrogen, halo, —SO2—CH3, nitrile, C1-C8-haloalkyl, imidazolyl, C1-C8-alkyl, —NR8*R9*, or —SO2—NR8*R9*; and R5* is hydrogen, halogen or C1-C8-alkyl; R8* and R9* are independently hydrogen, amino, C1-C8-alkylamino, di(C1-C8-alkyl)amino, or CC1-C8-alkyl optionally substituted by hydroxyl; or a pharmaceutically acceptable salt, or solvate thereof, to compositions and use of the compounds in the treatment of diseases ameliorated by inhibition of phosphatidylinositol 3-kinase.
