Abstract: A packaging structure having resilient positioning flaps can have a particular shape formed by folding a planar sheet including a left fixing portion, a right fixing portion, and a main body portion whose left and right edges are each respectively connected to a connecting portion. The connecting portions are connected to the left and right fixing portions, respectively. Two spaced-apart pressed lines are formed on each fixing portion so that the fixing portions can be bent toward the main body portion along the press lines. Each fixing portion is formed with an opening having a portion of its periphery formed with cuttings extending away from the opening to form resilient positioning flaps. When the package structure is folded and a product is extended therein from the openings, the resilient positioning flaps can be engaged in a concave space of the product to position the product in the packaging structure.

Abstract: A main power load signal and a main voltage reference signal correlated to a main power signal. A sub power load signal and a sub voltage reference signal correlated to a sub power signal. A reference voltage is provided and a boost voltage is determined according to a control signal. The main voltage reference signal and the sub voltage reference signal are compared, and when the first comparison result complies with a predetermined condition, a difference between the main voltage reference signal and the sub voltage reference signal is obtained to be further compared with the reference voltage. Then the control signal is determined. The main power load signal and the sub power load signal are compared, and then one of the sub voltage reference signal and the boost voltage is selected as a power source voltage of the sub power control circuit or the load sharing control circuit to generate an adjustment signal for determining current and voltage of the sub power signal.

Abstract: A low-profile dual-band high-isolation antenna module is fixed on a substrate and includes two high-frequency antennas and two low-frequency antennas located on two opposite sides of the substrate respectively. The bottom ends of the low-frequency antennas are connected to a grounding of the substrate. A decoupling element is disposed between the high-frequency antennas and the low-frequency antennas. The top end of each high-frequency antenna forms a bent portion, and so does the top end of each low-frequency antenna. The decoupling element has two ends extending to positions corresponding respectively to the low-frequency antennas but is not in contact with the low-frequency antennas or the high-frequency antennas. The bottom end of the decoupling element is connected to the grounding through at least one metal strip. The bent portions effectively reduce the space occupied by the antennas while the decoupling element provides isolation between the antennas.

Abstract: For efficient redundancy power supplying, a voltage drop device, a power selection device, a voltage detection device and a switch are provided in a power control circuit of a redundancy power supply system. The voltage drop device performs a voltage drop operation to convert a redundancy operating voltage into a standby voltage. The power selection device receives the main operating voltage and the standby voltage, and selectively outputting one of the main operating voltage and the standby voltage, which is of a higher level. The voltage detection device outputs a control signal according to a comparison result of the main operating voltage and a threshold. The switch is selectively conducted or interrupted according to the control signal. A voltage drop of power passing through the conducted switch is less than a voltage drop of power passing through the voltage drop device.
