Abstract: The invention discloses a continuous polyester fiber textile cloth that can be torn into pieces, processing equipment and a processing method. By ultrasonic hot-melting technology, the polyester fiber textile cloth is subjected to the high temperature generated by the high frequency generated by the action of a metal knife mold and an ultrasonic welding head, so that the thread of the loop layers and the base layer are melted in a line to form a thin line melting body that can be torn apart. The knife mold and the ultrasonic welding head are close to each other and resonate to generate heat. When they leave each other, the resonance disappears and the heat decreases, so as to realize the formation and temperature control of a linear high temperature zone.

Abstract: An electronic device may have a cover layer and an antenna. A dielectric adapter may have a first surface coupled to the antenna and a second surface pressed against the cover layer. The cover layer may have a three-dimensional curvature. The second surface may have a curvature that matches the curvature of the cover layer. Biasing structures may exert a biasing force that presses the antenna against the dielectric adapter and that presses the dielectric adapter against the cover layer. The biasing force may be oriented in a direction normal to the cover layer at each point across dielectric adapter. This may serve to ensure that a uniform and reliable impedance transition is provided between the antenna and free space through the cover layer over time, thereby maximizing the efficiency of the antenna.

Abstract: A method for routing data traffic in a communication network includes decoding, by a source node, an Internet protocol (IP) data packet to determine a destination node. A routing table for the destination node is retrieved. The routing table identifies a plurality of next-hop nodes associated with a corresponding plurality of routing paths to the destination node. A plurality of saturation metrics corresponding to the plurality of routing paths are determined using the routing table. Each of the plurality of saturation metrics is indicative of data traffic saturation along a corresponding one of the plurality of routing paths. A routing path is selected from the plurality of routing paths based on the plurality of saturation metrics. The IP data packet is forwarded to a next-hop node in the selected routing path.
