    摘要： Techniques are described for projecting content onto a display surface and for analyzing the hand of a user that is placed over the display surface, such as when the user is making a command gesture. Based on the location and known shape of the display surface, a surface depth map is calculated corresponding to the display surface. Points of the calculated surface depth map are then subtracted from respective points an observed depth map to produce a foreground depth map corresponding to the user hand. The hand may be further characterized and tracked based on the foreground depth map.

    摘要： The invention provides a method for lyophilizing integrated composition of pyrophosphorolysis activated polymerization (PAP) in an aqueous solution. It also provides lyophilized integrated PAP composition. Except for nucleic acid template, the integrated composition contains all components. For manipulation, simply add nucleic acid template in an aqueous solution to start amplification. In addition to the easy manipulation, the lyophilized integrated composition can be stored for prolonged period at ambiguous temperature.

    摘要： Disclosed herein is a method for improving Input/Output (I/O) performance in a host system having multiple CPUs. Under this method, various interrupt affinity schemes are provided, which associate multiple processors, interrupts, and I/O channels for sending the interrupts, thereby allowing the interrupts to be almost evenly loaded among the multiple I/O channels and processors. Also, data locality (“warm cache”) can be achieved through the interrupt affinity schemes that associate each interrupt to its source processor, namely, the processor originating the I/O request that results in the interrupt.
