  • Publication number: 20240310433
    Abstract: A probe mounting structure and a wafer-level reliability test system are provided. The probe mounting structure includes a probe mounting plate. The probe mounting plate is provided with mounting holes penetrating through a thickness direction of the probe mounting plate. A volume of each mounting hole is smaller than a preset value and is used to install a corresponding probe. Two ends of each probe are respectively connected to a corresponding first pad on a circuit board and a corresponding die of a wafer under test. Two sides of the probe mounting plate are in contact with the test circuit board and the wafer under test respectively, such that each of the mounting holes forms a sealed chamber. The mounting holes are filled with high-pressure gas to ensure that the wafer under test does not spark during high-voltage testing.

  • Publication number: 20210024658
    Abstract: The disclosure discloses a method for co-production of gelling and emulsifying pectins from chicory/Jerusalem artichoke pulp, including raw material pretreatment, extraction, filtration, concentration, alcohol precipitation, and drying. According to the cell wall structure and tissue characteristics of chicory/Jerusalem artichoke pulp, the disclosure targetedly adopts the salt extraction and the dilute acid extraction to sequentially produce gelling and emulsifying pectin products. The gelling chicory/Jerusalem artichoke pectin has characteristics of simple molecular structure, high purity, low degree of acetylation (DA), and high gel strength; and the emulsifying chicory/Jerusalem artichoke pectin has excellent emulsifying properties. The extraction method for chicory/Jerusalem artichoke pectin in the disclosure can provide two types of pectin at the same time, broaden the application range of chicory/Jerusalem artichoke pectin, and improve the processing utilization of chicory/Jerusalem artichoke pulp.

  • Patent number: 8848404
    Abstract: An exemplary power conversion system is disclosed including a DC bus for receiving DC power; a line side converter electrically coupled to the DC bus for converting the DC power to AC power; and a voltage source controller to provide control signals to enable the line side converter to regulate the AC power. The voltage source controller comprises a signal generator to generate the control signals based at least in part on a power command signal and a power feedback signal. The voltage source controller further comprises a current limiter to, during a transient event, limit the control signals based at least in part on an electrical current threshold. The voltage source controller further comprises a voltage limiter to, during the transient event, limit the control signals based at least in part on a DC bus voltage feedback signal and a DC boundary voltage threshold.

  • Publication number: 20060009842
    Abstract: Improved, adaptable tissue-type heart valves and methods for their manufacture are disclosed wherein a dimensionally stable, pre-aligned tissue leaflet subassembly is formed and its peripheral edge clamped between and attached to an upper shaped wireform and a lower support stent. A variety of adaptable structural interfaces including suture rings, flanges, and conduits may be attached to the support stent with or without an outlet conduit disposed about the wireform to provide a tissue-type heart valve adaptable for use in either a natural heart or in mechanical pumping devices. The methods include forming individual leaflets with a template and using the template to attach the leaflets together to form a tissue leaflet subassembly. The template and leaflets include a straight edge terminating in oppositely directed tabs, and a curvilinear cusp edge extending opposite the straight edge.
