Abstract: An electrical connection assembly includes two electrical connectors and a bridge connector. Each of the two electrical connectors includes plural terminals and an insulation housing that accommodates the terminals. The bridge connector is located between the two electrical connectors. The bridge connector includes an insulation body, a conductive plastic, plural signal terminals, and plural ground terminals. The conductive plastic is covered by the insulation body. The ground terminals and the signal terminals of the bridge connector are arranged at intervals. The ground terminals of the bridge connector are in electrical contact with the conductive plastic. When two opposite sides of the insulation body are respectively coupled to the two electrical connectors so as to be surrounded by the two electrical connectors, the ground terminals of the bridge connector are respectively in electrical contact with the ground terminals of the two electrical connectors.

When the tongue portion of the insulation body is coupled to the butt plug so as to be surrounded by the butt plug, plural ground terminals of the butt plug are in electrical contact with the conductive plastic.

Abstract: An electrical connector is configured to couple to a butt plug. The electrical connector includes an insulation body, plural signal terminals, plural ground terminals, and at least one conductive plastic. The insulation body has an accommodating recess. The signal terminals are located in the accommodating recess. The ground terminals are located in the accommodating recess, and the ground terminals and the signal terminals are arranged at intervals. The conductive plastic is located on a top surface of the insulation body facing the butt plug. When the butt plug is inserted into the accommodating recess of the insulation body, plural ground terminals of the butt plug are in electrical contact with the conductive plastic.

Abstract: A Totem Pole PFC circuit includes at least one fast-switching leg, a slow-switching leg, and a control unit. Each fast-switching leg includes a fast-switching upper switch and a fast-switching lower switch. The slow-switching leg is coupled in parallel to the at least one fast-switching leg, and the slow-switching leg includes a slow-switching upper switch and a slow-switching lower switch. The control unit receives an AC voltage with a phase angle, and the control unit includes a current detection loop, a voltage detection loop, and a control loop. The control loop generates a second control signal assembly to respectively control the slow-switching upper switch and the slow-switching lower switch. The control loop controls the second control signal assembly to follow the phase angle, and dynamically adjusts a duty cycle of the second control signal assembly to turn on or turn off the slow-switching upper switch and the slow-switching lower switch.

Abstract: A webpage data extraction device and a webpage data extraction method thereof are provided. The webpage data extraction device operates to: group the webpage data into URL groups according to URL relation of the webpage data; select a first webpage data and a second webpage data from each URL group; analyze the first webpage data and the second webpage data to derive a webpage node data set; group webpage node data of the webpage node data set into webpage node data groups according to XPath relation and text content relation of webpage node data of the webpage node data set; calculate respective text content sum for each webpage node data group; determine main webpage node data groups from the webpage node data groups according to the text content sums; decide main content extraction information based on XPath of the webpage node data included in the main webpage node data groups.

Abstract: A method of analyzing power usage and an electronic apparatus are provided. The method includes the following steps. Power usage data from power usage recording devices within a time interval are collected, wherein each of the power usage data includes a plurality of data points. A dissimilarity between every two of the collected power usage data is calculated. The collected power usage data are classified according to the dissimilarities into a plurality of classifications. The power usage data are displayed, wherein the power usage data belonging to different classifications are shown by different colors.

Abstract: A method and a power-saving control device for controlling operations of a plurality of computing units are provided. The method includes pre-estimating network service demands for the computing units within a next period. The method further includes: before the next period, calculating a first number and a second number of the computing units which are expected to be respectively in a busy state and a standby state within the next period according to the pre-estimated network service demands. The method further includes controlling the computing units such that the numbers of the computing units which are in the busy state and the standby state within the next period are respectively equal to the first number and the second number.

Abstract: A method for managing Internet protocol (IP) addresses in a network is provided. IP addresses are assigned to a plurality of virtual machines of servers in the network according to media access control (MAC) addresses of the virtual machines, and IP addresses are assigned to the servers according to MAC addresses of the servers. An active server and the virtual machines thereof respectively record the assigned IP addresses thereof in a recording unit. Then, the assigned IP addresses recorded by the recording unit are transmitted to a storage module in the network. Accordingly, the IP addresses assigned to the servers and the virtual machines could be handled properly in the network, and the servers and the virtual machines could be remotely controlled according to the IP addresses recorded in the storage module.
