摘要:
A control strategy for a multiple stage rotary compressor having compressive capacity output based on the demand of an air conditioning system. The constant variance in capacity to meet demand is obtained by recirculation of the multiple stages. Capacity is reduced to less than full capacity by recirculating the output of each stage back to the input of that particular stage. Capacity is increased up to full capacity by decreasing recirculation of the output of each stage back to the input of that particular stage. Additional stages and or portions operate in the same manner and provide further recirculation variability to provide a recirculation schedule based on demand.

Embodiments of present invention provide a method of splicing optical fibers. The method includes holding a first and a second fiber respectively by a first and a second rotary clamp; aligning axes of the first and second fibers to a common reference; moving the first and second fibers that are being held by the first and second rotary clamps onto a splicing machine; and causing the first and second fibers being spliced together by the splicing machine. A fiber splicing apparatus or system is also provided for performing the method thereof.

An optical coherence tomography system having real-time artifact and saturation correction includes an optical coherence tomography unit, and a signal processing and display system adapted to communicate with the optical coherence tomography unit to receive imaging signals therefrom. The optical coherence tomography system is a Fourier Domain optical coherence tomography system. The signal processing and display system includes a parallel processor configured to correct the imaging signals, in real time, to at least partially remove image artifacts and saturation based on a subset of image data within an image frame.

The methods and systems of this invention allow for independent adaptive control of ringing and overshoot effects in 2-dimensional array interpolation processes, including in image and video rescaling and analysis. The methods and systems can use either a column-wise or a row-wise interpolation, or a combination thereof. Each uses a respective preliminary interpolation of data, followed by ringing and/or overshoot control. Controllable parameters allow variability in the amount of ringing and/or overshoot retained in the interpolated data. The ringing and overshoot controls apply a local analysis of the data to adjust the preliminary interpolation results. The methods may be repeated iteratively, for example, to obtain a desired rescaling of an image data array.

Disclosed is a feedback detection circuit, adapted to provide a feedback detection signal wherein a converting circuit provides a driving power source to drive a load according to the feedback detection signal. The feedback detection circuit comprises an operational conversion circuit and a signal limitation circuit. The operational conversion circuit generates the feedback detection signal in response to a level of a detected node of the load. The operational conversion circuit has an operational amplifier, which modulates the level of the feedback detection signal in response to the level of the detected node. The signal limitation circuit is coupled to the operational conversion circuit for clamping a level rang of the feedback detection signal.

A method is disclosed for the Agrobacterium-mediated germline genetic transformation of soybean. The method is based on Agrobacterium-mediated gene delivery to individual cells in a freshly germinated soybean meristem, which cells can be induced directly to form shoots that give rise to transgenic plants. This method does not involve callus-phase tissue culture and is rapid and efficient.
摘要:
Transfecting biology cells with nucleic acid molecules (DNA, siRNA) is an essential prerequisite in elucidating how genes function in complex cellular context and how their activities could be modulated for therapeutic intervention. Traditionally studies are carried out on a low throughput gene-by-gene scale, which has created a huge bottleneck in functional genomic study and drug discovery. Development of high-throughput cell transfection technology will permit functional analysis of massive number of genes and how their activities could be modulated by chemical or biological entities inside cells. This invention describes design, construction of device and apparatus for high throughput effective cell transfection. Procedures and protocols for using the device and apparatus are also described in the application. Novel methods of using the device in cell-based assays are also disclosed.
