摘要： A surveillance security system is used for selectively storing motion image data of an object to be detected. The surveillance security system includes an image-capturing device for capturing images from an object; a memory module for storing the image data; and a controller for controlling a storage process of the memory module. The controller includes a sampling module for taking a plurality of image frames from the image data; and a control-signal generating module for receiving the image frames and generating a write enable signal by comparing the image frames, wherein the write enable signal is used for controlling the storage process of the memory module. A surveillance security method for selectively storing motion image data of an object is also disclosed.

摘要： An electrical receptacle to prevent injuries deduced by misoperation is provided in the present invention. The electrical receptacle includes a power socket, a direct current (DC) power supply, a detecting switch, a controller, and a relay form a circuit loop for detecting whether a power plug is inserted into the power socket. The detecting switch is placed under the power socket without any electrical connection with the power socket. A live wire is connected to the power socket via a switch of the relay and a neutral wire is connected to the power socket directly. The switch of the relay closes on condition of the relay is electrified by the DC power supply.

摘要： A scanning circuit includes n input ports K1˜Kn arranged in n rows L1˜Ln; and m−2 output ports W2˜(m−1) arranged in m columns P1˜Pm. The n rows and the m columns define a switch matrix including n*m switches. Ends of the switches in the same row are connected to one of the n input ports K1˜Kn, respectively. The ends of the switches in the column P1 are connected to ground. The ends of the switches in the same column of the columns P2˜P(m−1) are connected to a power supply VCC via resistors R2˜R(m−1) and the m−2 output ports W2˜W(m−1), respectively. The ends of the switches in the columns Pm are connected to ground via a resistor Rs and the power supply VCC via the resistors R2˜R(m−1) and diodes D2˜D(m−1), respectively.
