摘要： A method for quasi-synchronous tuning of wavelength or frequency of grating external-cavity semiconductor laser and a corresponding semiconductor laser are provided. A grating or mirror is rotated around a quasi-synchronous tuning point (Pq) as rotation center, so as to achieve the frequency selections by grating and resonance cavity in quasi-synchronous tuning, wherein the angle of the line between the quasi-synchronous tuning point (Pq) and a conventional synchronous tuning point (P0) with respect to the direction of light incident on the grating is determined according to the angle difference between the incidence angle and diffraction angle of light on the grating. According to present invention, approximately synchronous tuning of laser is achieved with a simple and flexible design.

摘要： Methods, systems, and apparatus, including computer programs encoded on computer storage media, for distributed data management. One of the methods includes receiving a plurality of feeds of streaming event data and routing feed data from each of the feeds to a respective channel of a plurality of channels, each of the channels being configured to store feed data until the feed data is consumed by a data sink, including routing feed data from a first feed to a first channel. A load metric for the first channel is determined to exceed a threshold. In response, a second channel is allocated for the first feed and feed data is redirected from the first feed to the second channel instead of the first channel.

摘要： A method for quasi-synchronous tuning of laser wavelength or frequency of grating external-cavity laser and a corresponding laser are provided. A grating or mirror is rotated around a quasi-synchronous tuning point (Pq) to achieve the quasi-synchronous tuning of frequency selections by grating and resonance cavity, wherein, on the xOy coordinate plane, from the perspective of actual physical space of the laser, the rotation center Pq(xq, yq) satisfying the quasi-synchronous tuning condition can be considered as being extended from the rotation center P0(x0, y0) under the conventional synchronous tuning condition to the region enclosed by two parabolas near P0. According to the present disclosure, approximately-synchronous tuning of laser is achieved with simple and flexible designs.

摘要： The present invention belongs to the technical field of integrated semiconductor circuits, and relates to a method for depositing a gate oxide and a gate electrode selectively. The present invention makes use of Octadecyltriethoxysilane's (ODTS') easy attachment to the Si—OH interface and difficult attachment to the Si—H interface, and selectively deposits the gate oxide and gate electrode materials, which avoids the unnecessary waste of materials and saves cost. Meanwhile, the present invention will transfer the etching of the gate oxide and gate electrode into the etching of SiO2 so as to reduce the difficulty of the etching process and increase the production efficiency.

The transformed data block signals are transmitted by a plurality of transmit antennas and received by a plurality of receive antennas. The received data is pre-whitened prior to maximum likelihood detection. In one embodiment, successive interference cancellation can be sued to improve system performance. Channel parameter estimation can be enhanced by weighting the channel impulse response estimates based upon a deviation from average.
