Abstract:
A base station of a wireless system comprises a local clock source and timing circuitry coupled to the local clock source. The timing circuitry is configured to adjust at least one parameter of the local clock source based at least in part on timing information extracted from designated portions of each of one or more frames of a synchronous transport signal received in the base station. The base station may further comprise a physical layer device, such as a mapper, configured to extract the timing information from the designated portions of each of the one or more frames of the synchronous transport signal. The designated portions of the one or more frames of the synchronous transport signal from which the timing information is extracted may comprise designated overhead bytes of the one or more frames, such as, for example, transport overhead (TOH) bytes.

A mounting assembly includes a circuit board, a securing member and a heat dissipating device. A retainer is located on the circuit board. The securing member includes a positioning portion and a claw connected to the positioning portion. The heat dissipating device includes a base attached to the circuit board and a number of fins perpendicularly located on the base. The number of fins defines a number of first air paths and a number of second air paths substantially perpendicular to the number of first air paths. The positioning portion is received in at least one of the number of first air paths and at least one of the number of second air paths, and the claw is engaged with the retainer.

Abstract:
A spectra shaping apparatus for chirped pulse amplification (CPA): uses a spectrum decomposing system with CTSI construction, a spectrum synthesizing system with CTSI structure that is optically symmetrical to the decomposing structure, and a spectrum shaping system including an aperture and a planar reflector for spectrum shaping function design. The apparatus accomplishes the following functions: firstly decomposing the spectrum of a chirped temporal pulse laser to a spectral domain; then shaping the spectrum in the spectral domain; finally synthesizing un-shiftily this shaped spectrum in the spectral domain into a temporal chirped pulse with a designed shape. The apparatus has the feature of fabricating easy, compacting the structure, requiring less space, and cheap in cost etc., which it can be the different types of configuration for different circumstance application, which it can be not only utilized in a general laser spectrum shaping and spectrum modulation, but also can be utilized for a high energy and ultra-high peak-power laser system in chirped pulse amplification with a large caliber and with a chirped pulse bandwidth of a few nanometers.
Abstract:
Phthalide derivatives and the use of which to manufacture the sensitizer or reverser of the antineoplastic agent are described. The phthalide derivatives can enhance the sensitivity of drug-resistance tumor cells against chemotherapy and decrease the drug-resistance of tumor cells 5-30 folder and enhance notably several chemotherapy agents-induced apoptosis of tumor cells.
Abstract:
A micro inertial measurement system includes a housing, a sensing module, and a damper. The sensing module includes a rigid sensing support, a measuring and controlling circuit board mounted on the rigid sensing support and an inertial sensor set on the measuring and controlling circuit board. The inertial sensor includes a gyroscope and an accelerometer. The sensing module is mounted in the housing. The damper is mounted in the housing and set in the gap between the sensing module and the inside wall of the housing. By use of the above-mentioned structure, the noise immunity of the inertial measuring system can be greatly improved, and the volume and weight of the inertial measuring system can be greatly reduced.
Abstract:
The present invention provides a connector assembly including mateable receptacle connector and plug connector. The plug connector includes a plug insulative housing, a number of plug contacts and a resilient locking member mounted to the plug insulative housing. The locking member includes a front section positioned on the plug insulative housing and a pressing section extending backwardly and upwardly from the front section. The front section includes a first locking protrusion having an inclined first guiding surface and a first locking surface. When the plug connector is inserted in the receptacle connector, the first locking protrusion is downwardly movable under the drive of the pressing section so as to lock with the receptacle connector.
Abstract:
A Coriolis mass flowmeter with at least one measurement tube (2) for forming a flow channel, at least one vibration generator and at least one vibration pick-up, the measurement tube (2) having one inlet end (4), two vibration sections (3a, 3b) and one outlet end (5) and being bent at least in sections such that two U-shaped or V-shaped vibration sections (3a, 3b) which run in essentially parallel planes are formed, and the vibration sections (3a, 3b) can be excited to vibrations by the vibration generator. The flow channel, except for the inlet end (4), the vibration sections (3a, 3b) and the outlet end (5), runs within a solid base (6).
Abstract:
A method of forming a front electrode of a solar cell includes a step of forming a sub-grid line and a main-grid line on the solar cell. The method further includes steps of: forming a lower layer of the sub-grid line on the solar cell using a lower paste by a first screen; drying the solar cell that is formed with the lower layer of the sub-grid line; forming an upper layer of the sub-grid line and the main-grid line simultaneously on the solar cell using an upper paste by a second screen; and sintering the solar cell that is formed with the sub-grid line and the main-grid line. A method of manufacturing a solar cell using the methods and a solar cell manufactured by the method are also provided.
