摘要： Circuits and method for sensing a system output voltage change and transmitting an electrical signal to an auxiliary winding on the primary side. In an embodiment, a primary side controller detects the electrical signal and turns a power switch on and off to transfer energy from a primary winding to a secondary winding. A secondary side controller generates a voltage pulse at a terminal of the secondary winding when the system output voltage is below a reference voltage. The secondary side controller includes an input terminal connected to a system output, an output terminal connected to a terminal of the secondary winding, and a ground terminal connected to a ground potential of the system output.

摘要： Disclosed is a process of preparing magnetite nanoparticles, comprising the following steps: 1) preparing a ferric salt mixed system, wherein a soluble ferric salt is dissolved in glycol at ambient temperature, and then urea and polyethylene glycol are added and mixed homogeneously to obtain the trivalent iron salt mixed system, the mass ratio of glycol to the trivalent iron salt being 15:1 to 60:1, glycol to urea being 20:1 to 100:1, and glycol to polyethylene glycol being 20:1 to 100:1; 2) reacting, wherein the trivalent iron salt mixed system is transferred into a reaction autoclave, sealed and placed into a heating device to react at a temperature of 200 to 300° C. for 8 to 72 hours; and 3) washing, wherein after the reaction system is naturally cooled down to ambient temperature, the product is taken out, and washed with anhydrous ethanol and water in turn to obtain the magnetite nanoparticles. The soluble iron salt includes ferric chloride, ferric sulfate, ferric acetate and ferric nitrate. The obtained nanospheres exhibit a uniform distribution of the particle diameter with a good dispersity in water. The nanospheres have superparamagnetism, and their particle diameter can be controlled by varying the reaction time as desired.

摘要： A cover assembly for a portable electronic device is described. The cover assembly has a cover comprising: two cover extensions extending substantially perpendicular from the cover. Each of the two cover extensions has an abutment towards a center. An angular spring with two wings and two upwards arcuate ends is included in the cover assembly, each of the wings forming a bias angle relative to a line between the two ends. Two housing extensions extend from a surface of the portable electronic device, each of the housing extensions has a protrusion mating the corresponding abutment, and a guide having a form substantially corresponding to the upwards arcuate end. When a force is applied to the center of the angular spring, the bias angle decreases and the upwards arcuate ends are urged upwards, thereby causing the abutments moving outwards, and unlocking the protrusions.
