Abstract: A method and a system for detecting stand-alone operation of a distributed generating system having a generating source connected in shunt with an independent power distribution system via a first branch breaker are proposed. A voltage or a frequency signal on the independent power distribution system is read. The wavelet transformation is performed on the voltage or frequency signal to form a time versus high-frequency component window and a time versus low-frequency component window for conveniently detecting the perturbation in the time domain of the signal. Next, whether the absolute value of the high-frequency component is greater than a threshold value and whether the duration is longer than another threshold value are determined. If both answers are yes, a stand-alone operation occurs. An alarm signal is immediately generated and sent to the first branch breaker to release the connection between the generating source and the power distribution system.

Abstract: An electric signal transmission connector assembly includes at least one plug and a receptacle mounted to an electronic apparatus. The plug and the receptacle are internally provided at two opposite positions with a permanent magnet each, so that the plug may be easily connected to the receptacle through magnetic attraction between the two magnets. The plug and the receptacle also include a plurality of terminals each. When the plug and the receptacle are magnetically connected to each other, the terminals thereof are contacted with one another to enable transmission of electric signals or supply of power via the plug and the receptacle. Two or more plugs may be stacked up to magnetically connect to the same one receptacle to save a lot of space by magnetically connecting a lower connecting section of an upper plug to an upper receiving section of a lower plug.

Abstract: A method of manufacturing LED light string includes the steps of forming an LED light body from multiple serially connected printed circuit boards, fixing the LED light body to a base, and connecting a light-transmissible shell to the light body to form a cluster lamp; preparing a power cord, to which multiple lamp sockets are serially connected; fitting multiple cluster lamps to the lamp sockets on the power cord, so that the LED light bodies are made to emit light. A lampshade is detachably engaged with each lamp socket. The lampshade and the lamp socket may be differently designed to create romantic feeling. The number of LED light bodies on each cluster lamp and the number of cluster lamps on one LED light string may be varied as desired to increase the brightness of the light string while reduce the manufacturing cost of the LED light string.

Abstract: A heat sink module includes a fan set and a heat sink plate. The fan set is integrated as a whole, reducing manufacture time, and the material of the fan set is plastic, thus reducing the weight as well. Due to the hook design of the fan set and the ear design of the heat sink plate, the number of screws is reduced. Furthermore, the screws pass through the first lug of the heat sink plate and the second lug of the fan set, so that the heat sink plate and the fan set are fixed on the motherboard, and thereby the number of the parts to be fixed by screws is reduced. Heat from the heat source on the motherboard is conducted to the fan set to be dispersed through the heat sink plate extending to the heat source and covering the fan set.

Abstract: A method that controls the distribution of plasma generated in a vacuum chamber, for example, as part of a plasma thin film deposition or plasma etching process. For thin film deposition, the method serves to minimize variations in film thickness caused by the variations of the film deposition conditions. The vacuum chamber includes a high-frequency-wave electrode connected to a high-frequency electric power supply and an earth electrode connected to ground potential. High frequency-electric power is fed to the high-frequency-wave electrode and peak-to peak voltages are measured at multiple measuring points on one of the two electrodes. The distribution of the plasma is controlled by adjusting the chamber pressure to minimize the differences between the measured peak-to-peak voltages.

Finally, the daughter board is mounted in the motherboard by a method such as surface mount design (SMD), and the through hole is filled with a conductive material to connect circuits on the daughter board and the motherboard to each other.

Abstract: A transflective electrophoretic display device is disclosed. The device is comprised of a transparent top substrate and both top and bottom substrates have an electrode structure. A plurality of separated walls and an electrophoretic display solution including a plurality of chromatic particles and a transparent liquid are imposed between the two substrates. A device with a display liquid or a filter plate is used to generate a variety of lights such as monochromatic, color-level or true color having a mixture of red, green and blue. The device of the present invention integrates the merits of the reflective and transmitted displayer, and can be used outdoors, indoors or in darkness. Otherwise, a back light module can compensate for the contrast of the displayer effectively.

Abstract: A folding chair includes front and back legs, a cushion frame, a cushion embedded in the cushion frame and has a hard board having air vents, a sound absorbing foam, and a back cushion connected with the inner edge of the front leg and includes a second hard board. The hard boards have curved surfaces form fitting with the human body. A securing hook has a bent hook to clasp with the cushion frame. An inserting section can make the cushion and a support block to be connecting together. The curved surfaces of the cushion and the back cushion are form fitting with the human body, and the sound absorbing foam can reduce the sound sent out from the air vents when sitting. When a child's center of gravity on the chair is shifted to the back of the cushion, the cushion does not tilt backwards.

Abstract: The invention involves an engine that the cylinder block contains a coupled piston formed by a main piston, an external piston. The external piston is sleeved outside of the main piston and uses the rods on the two sides to connect to the heart-shape groove on the two sides of the crankshaft inside the crankcase at the bottom of the cylinder block. It moves with the main piston in an upward stroke and in a downward stroke. It forms a direct fuel injection device in the cylinder without carburetor. It does not need to add lubricants in the fuels. Besides, the engine has increased compression ratio.

Abstract: A traffic cone counterweight structure, the base of the cone is preformed with a large-diameter opening at the center having a convex ring member of proper width at its mid-section along the inner edge. A plurality of dovetail through holes are annularly configured along the circumference of the opening of base at where it adjoins the convex ring member. The preformed base is placed in an existing mold for making an integrally-formed traffic cone for injection molding of cone body. The better fluidity material that is used for the cone body flows through the preformed dovetail through holes on the base to wrap around the convex ring member to conjoin the base and the cone body.
