Abstract: A multi-layered connector is disclosed. The multi-layered connector includes a first sub-connector and a second sub-connector. The first sub-connector includes a first elongated body. The second sub-connector includes a second elongated body, and two side arms elongated upwardly from opposite ends of the second elongated body. The side arms define slide grooves faced to each other for receiving the first sub-connector. The multi-layered connector further includes glue points that connect the first elongated body and the second elongated body. The multi-layered connector avoids solder bridges and solder cracks.

Abstract: A transflective liquid crystal panel includes a first substrate, a second substrate, a first polarizer disposed on the first substrate, a second polarizer disposed on the second substrate having a transmission axis perpendicular to that of the first polarizer and a polymer dispersed liquid crystal layer sandwiched between the substrates. The polymer dispersed liquid crystal layer includes a plurality of liquid crystal molecules and at least one polymer network. When a voltage difference between the substrates is equal to 0V, the liquid crystal molecules do not reflect incident light beams and are not pervious to incident light beams. When the voltage difference between the substrates is not equal to 0V, the crystal molecules reflect incident light beams and are pervious to incident light beams.

Abstract: A self-support power generating system, wherein an input terminal of a battery is connected to a power generator, and an output terminal of the battery is connected to a power converter. The power converter is to convert the direct current motor supplied by the battery into alternating current power, and respectively in connection with a power outlet and a motor, the motor is again connected to the power generator to form a loop circuit. With the series of the power generator charging the battery, the battery supplying power to the motor, and the motor driving the power generator, the self-support power-generating system is capable of achieving the purposes of feeding back electric power, and reducing environmental pollution and noise.
