摘要:
An electric machine has a stator and a rotor. The stator has a housing and at least one pair of magnetic poles. Each magnetic pole has a primary magnet and two auxiliary magnets disposed on respective sides of the primary magnet. All of the magnets are disposed on an inner surface of the housing. All the magnets of a magnetic pole have the same polarity.

The invention provides methods and compositions for the modulation of proanthocynidin (“PA;” condensed tannin) production in plants. The methods of the invention allow creation of plants having novel phenotypes, such as alterations in levels of PA or in the types of tissues in which PAs are produced. Altered expression of PA in plants may be achieved, for instance without significantly affecting anthocyanin content or overall secondary metabolite profiles. Alternatively, expression of PA in plants may be achieved while also affecting anthocyanin content.

A brushless motor has a stator and a rotor. The stator has a stator core with a plurality of inwardly extending salient poles and windings wound about the salient poles. The rotor has a shaft, a rotor core fixed onto the shaft, and magnets inserted in the rotor core for forming magnetic poles of the rotor. Each of the salient poles has a pole shoe with a pole face that extends along a circumferential direction confronting the rotor core and being spaced from the rotor core by an air gap. In a radial cross section of the motor, each of the magnetic poles of the rotor has an effective dimension (W) which is about 0.85 times to 1.2 times of the chord length (L) of each pole face.

A method of transmitting data between a plurality of base stations and a plurality of mobile stations is provided. The method includes ranking data links between the plurality of base stations and the plurality of mobile stations according to a quality criterion, and selecting a subset of data links for transmitting the data between the plurality of base stations and the plurality of mobile stations such that a predetermined requirement is satisfied. Selecting the subset of data links may include iteratively assigning a predetermined value to power of the data link having the lowest ranking and determining if the predetermined requirement is satisfied, until the predetermined requirement is no longer satisfied. The remaining data links may then be selected for transmitting the data between the plurality of base stations and the plurality of mobile stations.

Methods, devices, and computer program products facilitate the application of a content use policy based on watermarks that are embedded in a content. Watermark extraction and content screening operations, which can include the application of content usage enforcement actions, may be organized such that some or all of the operations can be conducted at different times by different devices. The watermark extraction results can be stored in a secure location and accessed by other devices at different times. These operations can be conducted by one or more trusted devices that reside in a home network. The home network can also include a gateway device that can coordinate the operations of the various network devices and/or delegate the various watermark extraction and content screening operations.
摘要:
The present invention relates to electronic technology field, and more particularly to CRT and projection system. A low power laser CRT based on parallel flow electron gun comprises a vacuum tube, a laser panel provided at one end of the vacuum tube and an electron gun provided at the opposing end. The electron gun adopts a parallel flow electron gun, wherein the parallel flow electron gun comprises a negative electrode, a G1 electrode and a control electrode, wherein the control electrode is connected to an electron beam current control system. The electron gun of the present invention adopts parallel flow electron gun to emit electron beam, so that the laser panel has even current density distribution so as to average the power consumption of laser panel to reduce the energy that is converted to heat.
