The invention provides a method comprising the steps of laminating a series of layers of film material and cutting perforations in the films of the laminate to provide a foraminous fabric. Further the method comprise seamed or unseamed industrial fabrics made according to the method.
Abstract:
Error bursts are detected and corrected in a communication system using shortened cyclic codes, such as shortened Fire codes. Data is loaded into a first error syndrome register and a second error syndrome register. The data in the registers may be evaluated to determine if the data bits contain a correctable error. Shortened zero bits are shifted into the second error syndrome register. A number of zero bits are shifted into the first error syndrome register to trap an error burst pattern in the data. A determination is made as to the number of zero bits shifted into the second error syndrome register to trap the location of the error burst in the data. Using the number of zero bits shifted into the second error syndrome register and the error burst pattern, the error in the data is located and corrected.
Abstract:
An array antenna is disclosed. In one embodiment, the array antenna facilitates transmission of data with amongst fixed radio units. The array antenna includes a number of antenna panels arranged in an hexagonal shape, one or more array control elements controlling the antenna panels, and one antenna routing element controlling the one or more array control elements.
Abstract:
A wireless network includes a plurality of base stations that provide a wireless communication capability for a plurality of mobile stations. Each base station includes a local clock unit with a clock divider that generates local clock signals from a master clock signal received from a master clock source. The base stations are partitioned into a plurality of clusters. A sync pulse is propagated to each base station of the wireless network in order to reset their respective clock dividers. resetting of the clock dividers provides synchronization of local clock signals among the base stations. The sync pulse is propagated to all bases stations within a first cluster wherein one of the base stations in the first cluster is also a member of a second cluster. The base station that is part of the first and second clusters then propagates the sync pulse to other base stations in the second cluster and so on until the sync pulse has been delivered to all base stations in the wireless network.
Abstract:
A method for handover execution in a wireless environment is provided that comprises communicating, by a mobile network, a handover command message to a physical layer of a mobile station to initiate a handover execution. The handover command message is received by the physical layer, which responds by tuning to a handed to frequency and by communicating physical layer bursts over the handed to frequency such that initial timing advance and power control setting characteristics are determined by the mobile network. The method also includes communicating a cease signal to stop communicating the bursts to the mobile station, which responds by ending the transmission of the bursts and by establishing a new communications link over the handed to frequency with the mobile network. The mobile station and mobile network may then couple to a voice or data path such that a wireless communication associated with the mobile station and the mobile network is facilitated.
Abstract:
A user is registered for an electronic peer-to-peer payment system by authenticating the user at an automated teller machine (ATM), receiving the user's mobile number and addressing a verification code to the user's mobile number, which the user must enter in order to be registered.
Abstract:
A user inputs a pattern consisting of a plurality of lines. The lines are classified by relative length, overall direction and degree of curvature. Where a line is started from a new position, the direction from the previous starting point is taken into account. The series of lines is then serialised into a key value, which may then be used to decrypt data stored on a device. This enables data to be securely stored since the key is supplied by the user at runtime and is not itself stored on the device.
Abstract:
A system for providing a fast access channel is disclosed. The system includes a transmitter configured to transmit a first long contention symbol and one or more subsequent long contention symbols. The first long contention symbol is followed by the subsequent long contention symbols. The system further includes a receiver configured to receive the first and subsequent long contention symbols and determine a contention code and a contention channel transmitted with the contention code based on the first and subsequent long contention symbols. Each of the first and subsequent long contention symbols includes a long cyclic prefix and a number of identical contention symbols.
Abstract:
A wireless networking system uses mobile and fixed transceivers to achieve a network with changing topology. A routing process includes quality-of-service considerations in the network to allow for features such as file or other data transfer, streaming audio and video, digital telephone communications, etc. The routing process adapts to transceiver units entering, leaving, or moving within, the network. Auxiliary networks such as the Internet, campus or corporate intranets, home networks, etc., can be accessed through the wireless network. Features, designs and user interfaces for the units are described. Security and access control of media content and other data is presented.
Abstract:
A method for determining direction of transmission using an antenna array having a number of panels is disclosed. Each panel is configured to receive signals. According to one aspect of the method, each of the panels is directed to receive signals from a transmitting node. For each panel, a first table having data representing received signal power difference between the panel and a first neighboring panel and a second table having data representing received signal power difference between the panel and a second neighboring panel are built. The panel with the maximum received power is identified. For the identified panel, a first gain table and a second gain table corresponding to its first and second neighboring panels are searched to identify a first transmission angle and a second transmission angle, if any. A transmission angle relative to the transmitting node is determined using the first and second transmission angles.
