Abstract: A flexible paper straw includes a paper tube which is a spiral tube having a tube wall with at least two layers and formed by using glue and paper material while the paper material is paper sheet material having at least two layers of paper, a first layer of paper and a second layer of paper; and a compressed corrugated portion which is a circular tube having parallel ridges and grooves on longitudinal sections thereof, formed on the tube wall of a part of the paper tube with a certain length and able to be bent freely.

Abstract: A method for manufacturing flexible paper straws and flexible paper straws are revealed. The method includes the steps of preparing a paper tube which is a spiral tube by glue and paper, inserting a support shaft into the paper tube axially, placing the paper tube with the support shaft between a first roller and a second roller before curing of the glue while the first and second rollers are in parallel and having a plurality of circular grooves on a cylindrical surface thereof, rolling the paper tube by the first and second rollers to form a corrugated portion on a part of the paper tube, squeezing the corrugated portion to compress the corrugated portion for a period of time for curing the glue and holding shape of the corrugated portion, and removing the support shaft to get a flexible paper straw which is bendable at the corrugated portion.

Abstract: A gateway module, a communication method, and a computer program product thereof are provided. The gateway module is adapted for use in a network framework comprising a mobile station, a plurality of interworking units, a first wireless network, and a second wireless network. The mobile station is located within the signal coverage of the first wireless network and the second wireless network, and accepts network service provided by the first wireless network. The gateway module receives a handover request signal of the first wireless network, selects a handover interworking unit from the interworking units according to the handover request signal, and transmits the handover request signal to the second wireless network. Thereby, the mobile station can handover to the second wireless network to accept the network service provided by the second wireless network.
