    • An inverter circuit (500) having a drive transistor (102) that operably couples to a voltage bias input (101) (and where that drive transistor controls the inverter circuit output by opening and closing a connection between the output (105) and ground (104)) is further operably coupled to a feedback switch (401). In a preferred approach the feedback switch is itself also operably coupled to the voltage bias input and the output and preferably serves, when the drive transistor is switched “off,” to responsively couple the voltage bias input to the drive transistor in such a way as to cause a gate terminal of the drive transistor to have its polarity relative to a source terminal of the drive transistor reversed and hence permit the inverter circuit to operate across a substantially full potential operating range of the drive transistor.

The base (140) has an air inlet (142) and a vent hole (148) defined therein. The vent hole (148) is near the air outlet (180) and between tip portions of the blades (240) and the sidewall (160). In a preferred embodiment, the base (140) has a supporting portion (144) disposed in the air inlet (142). Two ribs (146) extend from a periphery of the supporting portion (144) towards the base (140). One of the ribs (146) is arranged adjacent to the air outlet (180) and has a changeable width which is gradually increased along a direction from the supporting portion (144) to the base (140).

    • An embodiment of the present invention may be a system or method for simulating the flow of a single-phase fluid flow. Markers represent a moving fluid boundary of the single-phase fluid at a first point in time. The moving fluid boundary separates a simulation space into a fluid space and a non-fluid space. The single-phase fluid inhabits the fluid space. A signed distance function is evaluated at points surrounding the moving fluid boundary based upon markers. The curvature of the moving fluid boundary based on the signed distance function is evaluated near the markers in the non-fluid space. The curvature is not evaluated at the moving fluid boundary. The velocity of the fluid is calculated based upon the curvature of the level set in the non-fluid space. Update the position of the moving fluid boundary at a second point in time based on the velocity of the fluid.
    • 本发明的实施例可以是用于模拟单相流体流的流动的系统或方法。 标记表示在第一时间点的单相流体的运动流体边界。 运动流体边界将模拟空间分成流体空间和非流体空间。 单相流体居住在流体空间。 基于标记在运动流体边界周围的点处评估带符号距离函数。 基于有符号距离函数的运动流体边界的曲率在非流体空间中的标记附近进行评估。 在运动流体边界处不评估曲率。 基于在非流体空间中设定的水平面的曲率来计算流体的速度。 基于流体的速度在第二时间点更新移动流体边界的位置。

    • One facilitates determination of a path that comprises a plurality of specific locations (201). In an optional though preferred embodiment these specific locations comprise locations where a given functional ink will preferably be printed using a continuous printing spray. Also in an optional though preferred embodiment this path will also avoid at least one predetermined area (701) where such a functional ink should not be printed. In a preferred approach this process (100) generally provides for identifying (101) these specific locations and further identifying (102), when applicable, the one or more predetermined areas to be avoided. This process then preferably uses a processor to effect at least one (and preferably both) of using (103) a genetic algorithm to identify a preferred path that includes the plurality of specific locations and using (104) an A* algorithm to process a candidate path to provide a selected path that includes the plurality of specific locations while also avoiding the at least one predetermined area.
