    摘要： A high voltage, high power multi-level drive structure includes a plurality of neutral-point-piloted (NPP) converter cells stacked together. At least one clamping diode is connected to one or many NPP converter cells to provide a neutral-point-pilot-clamped (NPPC) converter structure. Flying capacitors connected to the NPPC converter structure yield a neutral-point-clamped-flying-capacitor converter cell structure.

    摘要： The invention provides a method for identification of alleles. In this method, genomic DNA is used as target. Multiple allele-specific PCR amplification are carried out with a group of primers comprising one or more allele-specific primers for a target gene, a universal primer, and a common primer; and a DNA polymerase without 5′ to 3′ exonuclease activity. The PCR products are hybridized with tag probes immobilized on a DNA chip. Results are determined based on the signal intensity and the position of the probe immobilized on the array. Each allele-specific primer comprises a unique tag sequence at the 5′ end. Each tag probe immobilized on the DNA chip comprises a sequence identical to its corresponding tag sequence; and each tag probe hybridizes only with the complementary sequence in the PCR amplification product.

    摘要： A multilevel converter includes at least one phase each including several cascaded basic units each including a first switching element, a second switching element, and a separate and electrically isolated DC source (SDCS). The SDCS is electrically coupled between the first switching element and the second switching element in each basic unit. Each of the adjacent pairs of the basic units are electrically crosswise coupled together by electrical coupling of the first switching element of a first basic unit of the two adjacent basic units to the second switching element of a second basic unit of the two adjacent basic units, and electrically coupling the second switching element of the first basic unit to the first switching element of the second basic unit.

    摘要： Techniques are generally described related to a pedestrian safety system. One example pedestrian safety system may include a sound collector configured to collect an audio signal in an environment of a pedestrian; a processor configured to analyze the collected audio signal to determine whether the audio signal is associated with a vehicle and a distance between the vehicle and the pedestrian; and a notification device configured to notify the pedestrian when the processor determines that the audio signal is associated with the vehicle and the distance is less than a predetermined distance.
