Abstract: The wrapped rim provides an “S” shaped rim with simple configuration. It is easy to use in storage appliance. The cross section of the wrapped rim is “S” shaped; the upper and lower openings of the “S” shaped rim are used as the first and second inserting slots. The product provides wrap edges of two cross sections simultaneously through altering the shapes of wrapped rim. It is simple to process, easy to operate, and can eliminate the gap between the wrapped rim and product edge effectively through changing the shapes of wrapped rim. The part of wrapped rim to be touched frequently is arc shaped, that can avoid injury. The wrapped rim can not only serve as product protection and decoration, but also enhance the product strength.

Abstract: Slidable storage container assembly is constructed through the main component of storage container and locating connection of the sliding trail. This assembly can reduce the maintenance costs and increase efficiency. The assembly is particularly applicable to mesh storage container. Moreover, the slidable storage container assembly and sliding trail has simple configuration, easy to mount and dismount. The storage container assembly includes the storage container and sliding device with fastening connection and locating connection. The assembly can be easily dismounted when the storage container and sliding device is malfunction or needs to be replaced. The procedures of position adjustment and dismounting of the main component can be avoided, that conveniently speeds up the installation and dismounting, therefore it is beneficial to the office and other uses.

Abstract: A method and a device for processing contact information group are proposed. The method includes: entering a contact interface according to a first operation command from an user; displaying a contact in a contact list corresponding to a focus group as picked according to a second operation command from the user; and identifying a targeted group of the contact and moving the contact to the targeted group according to a third operation command from the user. By using the present invention, the user can rapidly groups all the contacts through a single operation interface.

Abstract: The invention relates to an under shelf mounted drawer and the mounting method. The drawer is assembled by an independently mesh container and a mounting unit which is installed on a shelf. The drawer is made of two meshes which are bended and welded together. It is wrapped by C rim on top edge, a pair of lugs welded on opposite top side of the drawer and a plastic part on it for better slide and stop. The mounting unit is attached to a shelf and has a pair of spaced apart drawer supports that support the drawer under a shelf When the drawer is mounted under the shelf, each lug on the drawer is hanged by the mounting unit which supports the drawer under the shelf. It is slidable between a closed position and an open position relative to the mounting unit.

Abstract: A receiving circuit, a transmitting circuit, a micro-controller, and a method for power line carrier communication. The receiving circuit includes: an analog amplifier, a receiving filter, an analog-to-digital converter, a digital mixer, a digital filter, and a digital demodulator connected successively. The transmitting circuit includes: a digital modulator, a gain controller, a digital-to-analog converter, a transmitting filter, and a transmitting amplifier connected successively. The micro-controller includes a central processor and the receiving circuit or the transmitting circuit. The method for power line carrier communication can be implemented based on the receiving circuit or the micro-controller.

Abstract: The present invention provides a micro-controller, a processing method and device for power line carrier signal reception, where the method includes: an analog mixer mixes received power line carrier signals, an analog filter filters the mixed power line carrier signals, an analog-to-digital converter converts the filtered signals, a digital mixer mixes converted signals, a digital filter filters the mixed signals and a digital demodulator demodulates the filtered signals to obtain base band data. The present invention also provides a corresponding device and a micro-controller including the device. The technical solution of the present invention can modulate the carrier signals of any frequency to a fixed frequency through two-stage frequency mixing, so that demodulation of power line carrier signals with any frequency is possible.
