Abstract: An adapter including an accommodating element, a driving element having a driving unit, and multiple electrical connectors is provided. The accommodating element has a first space and multiple second spaces. The driving element is sleeved to the accommodating element along an actuating axis. The driving unit has a first electrical connecting portion. In a storage state, the driving unit is stored in the first space, and the electrical connectors are stored in the second space. In an operating state, the first electrical connecting portion of the driving unit is coupled to one of these electrical connecters. Then, the driving unit can enter the second space where the electrical connector stays originally, and at least part of the electrical connector is pushed out of the accommodating element. A using method of the adapter is provided.

Abstract: A power socket set including a first power socket and a second power socket is provided. The first power socket includes a first base, at least a first type of inserting port and a second type of inserting port. The first type of inserting port and the second type of inserting port are configured in the first base. The second type of inserting port is used to be inserted for a first type of plug or a second type of plug. The second power socket includes one of the first type of plug and the second type of plug for inserting into the second type of inserting port, at least a third type of inserting port and a second base. Wherein, the foregoing first type of plug or second type of plug is configured in the second base. The third type of inserting port is configured in the second base.

Abstract: An energy-saving central control system and energy-saving lighting devices comprised thereof is provided. The invention stores power produced from retail electricity during off-peak hours and electricity generated by renewable energy sources, and controls the electricity output by means of control equipments. The control equipment has an energy-saving central control system. The energy-saving central control system includes a control module, a management module, a cloud transmission module, and a warning module that are electrically connected to one another. Accordingly, when an electrical appliance is electrically connected to system, the electrical appliance can be turned on or off, and can be monitored for its condition of electricity consumption and usage condition.

Abstract: Broken links in a sensor network are avoided by representing the network as a DODAG. A rank associated with each node defines a position of each node relative to other nodes, and the rank is in a form of a proper fraction, and the rank of each node never increases to enable loop-free routing.

Abstract: The present invention discloses an object image detection method, which uses a coarse-to-fine strategy to detect objects. The method of the present invention comprises steps: acquiring an image and pre-processing the image to achieve dimensional reduction and information fusion; using a trained filter to screen features; and sequentially using a coarse-level MLP verifier and a fine-level MLP verifier to perform a neural network image detection to determine whether the features of the image match the features of the image of a target object. The present invention simultaneously uses three mainstream image detection methods, including the statistic method, neural network method and adaboost method, to perform image detection. Therefore, the present invention has the advantages of the rapidity of the adaboost method and the accuracy of the neural network method at the same time.

Abstract: An etching apparatus is described, including an etching chamber, a gas pipe, a gas distribution plate and a heater. The gas pipe is disposed above the etching chamber for delivering a gas to the exterior surface of the etching chamber. The gas distribution plate is disposed at the outlet of the gas pipe, including a plate body and an inner collar-shaped part thereon facing the outlet of the gas pipe. The inner collar-shaped part and the portion of the plate body around the inner collar-shaped part each has multiple through holes therein. The heater is disposed around the space between the gas pipe and the etching chamber for heating the gas flowing out of the gas distribution plate.
