Abstract: A method for controlling a grid-connected power supply system having multiple power supply modules, a relay commonly connected to output terminals of the power supply modules and connected between the power supply modules and a mains power grid, and a controller controlling each power supply module and the relay. The method is performed by the controller after the grid-connected power supply system is started and has steps of determining if each power supply module outputs power, activating each power supply module and charging an energy storage capacitor of the power supply module, and activating the relay when the stored voltages of the energy storage capacitors of all the power supply modules are greater than a preset peak voltage of the mains power. Accordingly, required number of relays is reduced and the size of the system can thus be more compact.

The signal shaping circuit processes an input signal and transmits the input signal to the filter circuit. The filter circuit filters off narrow pulses of the input signal. The pulse width compensating circuit compensates the wide pulses of the input signal and outputs an output signal.

Abstract: Technologies are described herein for generating and changing credentials of a service account. In one method, a credential schedule is retrieved. The credential schedule specifies when a plurality of credentials are scheduled to be changed. A determination is made whether a current credential associated with the service account is scheduled to be changed according to the credential schedule. Upon determining that the current credential is scheduled to be changed, at least part of a new credential is generated. The current credential is replaced with the new credential for the service account.

Abstract: A system and method for balancing a battery pack is disclosed. The method includes the step of monitoring voltages for all batteries in the battery pack and if the voltages of any two batteries are out of balance, then, issuing a balancing command to charge the battery that is relatively lower in voltage between the two until the voltage of the battery attaining a preset voltage. The battery-pack balancing system includes a battery-monitoring unit and a battery-balancing unit. The battery-monitoring unit monitors the voltage of all the batteries in the battery pack and, when the voltages of any of the two batteries in the battery pack is out of balance, issues a balancing command to charge the battery that is relatively lower voltage in the battery pack.

Abstract: A container structure includes a container formed as a dish structure, which has a dish bottom that is a bottom of the container and is formed a convex. The convex has a plurality of trench distributed radially and a plurality of grooves surrounded the convex. The convex of the dish bottom has height difference so that liquid flows along the convex into the grooves of the dish bottom. Therefore, some liquid on an upper surface of the convex of the dish bottom flows into the grooves while hydrous food is put on the container. Besides, some other liquid flows into the grooves by guiding of the trenches, and the liquid and food on the container are separated.

Abstract: The invention provides a photochromic dye of a structure containing a common structure of spirooxazine series compounds and three substituents. The photochromic dye according to the invention exhibits characteristics of a high heat stability, good light fatigue resistance, high sensitivity, extremely degradation rate and the like. This photochromic dye can be formulated with suitable organic solvents and used as photochromic functional colorants under UV light excitation. Further, this photochromic dye can be synthesized and purified in simple steps with cheap raw materials and hence at a greatly lowered production cost.

Abstract: The present invention relates to a textile ink-jet printing-purpose disperse dye micro-emulsion agent, which uses dispersing agents such as sodium polynaphthalene formaldehyde sulfonates, surfactants such as POE NP ether, and silicone derivative emulsion-type defoaming agents and bactericidal fungicidal agents for ink-jet CMYK four-color disperse dyes forming a stable dye micro-emulsion through micro-jetting homogenized emulsifier. This invention focuses on the disperse dyes suitable for polymers, applying a low-cost environmentally protective micro-emulsion agent in the ink protection technology so that the O/W model becomes a stable and homogenized system. This gives the textile ink-jet printing-purpose disperse dye micro-emulsion agent, with a dye particle diameter lying below 300 nm and high storage stability, rinse, sublimation, and light fastness over 4.

Abstract: A method of fabricating shallow trench isolation structures. A substrate over which a polysilicon layer and a masking layer are formed is provided. An opening is formed within the polysilicon layer and the masking layer. A trench is then formed within the substrate. An oxide layer is formed within the trench, and the surface of the oxide layer has a same level as the surface of the masking layer. The masking layer is removed and a thermal process is performed to transform the polysilicon layer to a silicon oxide layer. The silicon oxide layer is removed by an wet etching process and a shallow trench isolation structure is accomplished.
