摘要: The invention discloses a pitch control system for a wind turbine and a method, comprising a main controller, a secondary controller, a motor and a pitch gearbox, wherein the main controller is connected with a plurality of the secondary controllers through a communication bus; each blade corresponds to one controller and at least two motors, and one pitch gearbox is driven by each motor. The main controller is used for calculating a pitch expected value according to wind speed as well as power and rotation speed of a generator; and the motor is driven by the secondary controller according to the pitch expected value, so as to drive the pitch gearbox and hence drive the blades to vary a pitch angle.

摘要: Methods for introgressing an allele of interest of a locus associated with a yield trait into Zea mays germplasm are provided. In some embodiments, the methods include providing a Zea mays plant that contains an allele of interest of a locus associated with a yield trait, wherein the locus associated with the yield trait is identifiable by PCR amplification of a Zea mays nucleic acid with a pair of oligonucleotides primers as disclosed herein, and introgressing the allele of interest into Zea mays germplasm that lacks the allele. Also provided are methods for identifying Zea mays plants that contain at least one allele associated with improved yield, improved maize plants, elite Zea mays plants, biomass produced from improved Zea mays plants, isolated and purified genetic markers, and compositions that include an amplification primer pair capable of amplifying a Zea mays nucleic acid to generate a Zea mays marker amplicon.

摘要: An interrupt coalescing scheme for high throughput TCP offload engine and method thereof are disclosed. An interrupt descriptor queue is used, that TCP offload engine saves TCP connection information and interrupt information in an interrupt event descriptor per interrupt. Meanwhile the software processes an interrupt by reading interrupt event descriptors asynchronously. The software may process multiple interrupt event descriptors in one interrupt context.

摘要: Within several applications the ability to localize an individual within an environment is beneficial. However, existing indoor localization approaches depend upon at least one of two assumptions. First, the subject(s) localization is achieved by localizing a wireless device carried by the subject and second, wireless fingerprints are established for the localization via a site survey being performed before a system can actually localize the subject(s). However, in many application scenarios, neither of the above two assumptions are true, namely that the user is not carrying an active wireless device or that the site has been surveyed. Accordingly, embodiments of the invention provide for subject localization by a dynamic calibration of wireless signals between a receiver and a transmitter, where neither the receiver or transmitter are associated with an electronic device carried or worn by the subject.
