摘要： Embodiments of the invention are directed to apparatus, methods, and applications involving the actuation of a semi-insulative working fluid by electromechanical forces based on electrowetting-on-dielectric (EWOD) and liquid dielectrophoresis (liquid DEP) mechanisms that are controlled by the frequency, but not the magnitude, of an AC voltage (i.e., ‘frequency-addressable). In the various apparatus embodiments of the invention, a single, frequency-addressable electrode pair includes at least one electrode that has a spatially-varying dielectric coating thickness and thus a spatially-varying electrode gap wherein at least a portion of which a volume of a working fluid can stably reside under no influence of an applied voltage. In an exemplary aspect, a frequency-addressable, bistable apparatus includes at least one wider gap and one narrower gap associated, respectively, with a thicker and a thinner dielectric coating thickness of the electrode(s). The working fluid resides in only one of the at least two gap regions only under the influence of capillary force. A brief burst of AC voltage at a selected high frequency or low frequency will move the liquid from one gap region to another (and back) by one of an EWOD-based and a DEP-based force. In an alternative aspect, an analog apparatus has a continuous, spatially-varying electrode gap in which the dielectric coating thickness on the electrodes varies smoothly in an inverse manner. Various applications to a display device, fiber optic coupler and attenuator, controlled liquid volume dispensers, spotting arrays, well plate apparatus, and others are presented, along with control methods.

摘要： A method and system for implementing zero copy transmission of streaming media data are disclosed in the present invention, and the method and system are based on Linux network protocol stack. The method comprises: when a streaming media server receives a data request from a user equipment, it performs a system call of data transmission, reading the streaming media data out from the disk space and writing it into a user data buffer; packaging the streaming media data stored in the user data buffer as real-time transmission protocol packets which are transmitted applying streaming media packets whose head and load are separated. The method and system of the present invention sufficiently use the DMA function and SG (Scatter/Gather) function of a network card to implement zero-copy transmission of the streaming media data.
