摘要:
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.

An intelligent gain controller (IGC) for an on-frequency repeater implements a method for identifying a desired narrow band signal within a broadband RF signal. Thus, a candidate narrow band signal within the broadband signal is isolated. The isolated narrow band signal is then processed to detect repeating features of the narrow band signal. The detected repeating features are then analyzed to identify the signal type of the isolated narrow band signal. System gain of the in-frequency repeater can be controlled based on the power level of the identified narrow band signal.

A cooling fan includes a frame (100) and an impeller (200) with blades (240) disposed in the frame (100). The frame (100) has a base (140) and a sidewall (160) extending from a periphery of the base (140) with an air outlet (180) defined therein. 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).
摘要:
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.

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.

Systems and methods for transdermal drug delivery with controlled heat are provided. Such systems can comprise a heating apparatus that includes an exothermic chemical composition, typically in the form of individual heating elements. The heating apparatus can be exposed to ambient oxygen through a cover. The cover can reduce the amount of ambient oxygen capable of contacting the chemical composition compared to when the cover is not present. In some embodiments, the heating apparatus can include more than one heating element. The systems can further include a drug-containing layer that includes a drug. The drug-containing layer can have a surface area of about 50 cm2 to about 400 cm2. The systems of the present invention can be deliver ketoprofen in an amount sufficient to produce a mean blood plasma concentration of ketoprofen in a human subject of at least 45 ng/ml within four hours after initial application of the system to a skin surface.

An energizable design image portion (203) of a provided design pattern is printed on a provided substrate (201) using a functional ink comprised of at least one energy emissive material. A passive design image portion (202) of that design pattern is then also printed on that substrate using at least one graphic arts ink. In a preferred embodiment this apparatus may further comprise electrically conductive electrodes (204) on the substrate to permit selective energization of the energy emissive material to thereby induce illumination of the energizable design image portion of the design pattern.
摘要:
In a multiple input/multiple output wireless communication system, a receiving signal is compensated based on a wireless channel state information matrix converted by lattice reduction. The distortion of the modulation constellation diagram of a signal is considered, a detection signal is processed, and an intermediate signal table containing at least two intermediate signals is obtained to increase the area for the detection signal to be decided correctly, thereby to improve the possibility of the correct detection of the signal. Then a candidate signal table is obtained from the intermediate signal table and, based on the candidate signal table, a decision signal for a transmitting signal is obtained, thereby improving the accuracy of the detection of the transmitting signal. When at a high signal-to-noise ratio, the bit-error performance approaches the bit-error performance of a system using maximum likelihood detection algorithm, while causing no significant increase in computation complexity.
