摘要:
A micro-electro-mechanical generator has a liquid chamber, a heating block, an elongated elastic piezoelectric plate and a pair of electrodes. The liquid chamber is defined by bottom blocks which include the heating block and side walls, and can maintain a liquid. The heating block generates bubbles within the liquid chamber. The elongated elastic piezoelectric plate has a piezoelectric material layer, and is positioned in the liquid chamber adjacent to an upper portion of the heating block. The elongated elastic piezoelectric plate is deformable by contact with the bubbles, wherein a first end of the elongated elastic piezoelectric plate is a free end and a second end of the elongated elastic piezoelectric plate is a fixed end. The pair of electrodes are electrically connected to the piezoelectric material layer.

A method and apparatus for generating uniformly sized spherical ice particles. The apparatus comprises a water feed pump, a vacuum chamber connected to the water feed pump and having a water spray nozzle, boosters discharging the vapor from the vacuum chamber to maintain the inside of the vacuum chamber below a desired pressure and compressing it, a condenser for condensing the vapor being compressed by the boosters, and a vacuum pump for removing noncondensable gases from the condenser. The method comprises the steps of decreasing the pressure of the vacuum chamber below the first pressure, feeding water from the water source to the spray nozzle of the vacuum chamber, making spherical ices by spraying the water being fed from the nozzle into the inside of the vacuum chamber, in which the size of the droplets being sprayed is below a desired size, during said ice making step, maintaining the pressure of the vacuum chamber below the second pressure by discharging the vapor from the vacuum chamber and compressing the vapor to increase its saturation temperature above room temperature, condensing the compressed vapor within the condenser using water at room temperature as coolant, and draining the water being condensed during the condensing step and removing noncondensable gases.

The present invention relates to a method of preparing high-strength coated whole cottonseed for livestock feed, wherein the germination ability of whole cottonseed is removed using high-temperature and high-pressure steam, and the surface of whole cottonseed is coated with gelatinized starch with high viscosity, which is prepared by gelatinizing starch in a preparation process. According the method of the present invention, since the germination ability of whole cottonseed is removed, release of foreign genes into the domestic environment, which may occur when using whole cottonseed for livestock feed, may be fundamentally prevented, and thus the method of the present invention may contribute to protection of domestic plant genetic resources. In addition, the use of gelatinized starch with increased viscosity, which is prepared by gelatinizing starch in a preparation process, may dramatically increase the selection range of coating agents. Furthermore, since coated whole cottonseed can be prepared without a drying process, which consumes a large amount of energy, the method of the present invention may increase economic effect by resolving economic problems, such as high production costs, encountered when preparing whole cottonseed for livestock feed.

Embodiments of the invention are generally directed to conversion and processing of deep color video in a single clock domain. An embodiment of a method includes receiving one or more video data streams, the one or more video data streams including a first video data stream, the first video data stream being clocked at a frequency of a link clock signal. The method further includes converting the first video data stream into a converted video data stream having a modified data format, wherein the modified data format includes transfer of a single pixel of data in one cycle of the link clock signal and the insertion of null data to fill empty cycles of the converted video data stream, and generation of a valid data signal to distinguish between valid video data and the null data in the converted video data stream. The method further includes processing the converted video data stream according to the frequency of the link clock signal to generate a processed data stream from the converted video data stream, wherein processing includes using the valid data signal to identify valid video data.

A method of forming a frame in a Mobile Multi-hop Relay (MMR) system, and a system for implementing the method are provided. In a multi-hop relay system, when a relay station of a specific layer receives data, the relay station receives data from both a higher layer and a lower layer. When the relay station transmits data, the relay station transmits data to both the higher layer and the lower layer. By doing so, data reception and data transmission are exclusively performed without interfering with each other, and the method and the system are easily applied to the multi-hop MMR system.
