Patent CA-2207538-C (CA)

Abstract: A Virtual Path Group (VPG) technique that utilizes network elements (NEs), i.e.,nodes, that are visible to ATM specific defects, and allows for fast ATM virtualconnection/restoration with a minimum of processing.  This is realized by employing a Virtual Path Group transport architecture comprises at least one (1) working route, one (1) protection route, and VPG bridge and selector functions at each end of the routes. It is applicable to 1+1, mesh and ring protection switching and is extensible to any virtual connection segment or end-to-end network (cross-subnetwork) virtual connections, and extensible to 1:1 and M:N protection switching. Additionally, the protection switching arrangement of the invention includes an architecture for the Virtual Path Group (VPG) concept in which the associations among individual ATM virtual channels (VP/VCs) and VPGs are maintained entirely within the network element management function. This allows VPG support to be added to ATM systems and networks with minimum change from current ATM standards. In particular, no changes are required to the Virtual Path Identifier/Virtual Channel Identifier (VPI/VCI) addresses carried within each ATM cell across ATM interfaces. Further, defect type indication is realized via a new, for example a F4, segment level Operation and Maintenance (OAM) cell, to initiate the appropriate restoration action downstream. The technique differentiates between physical layer and ATM layer defects. An algorithm is employed in an embodiment of the invention todetermine appropriate VPG protection switch and signaling actions, driven by the F4 defect type OAM cells. Moreover, for interworking with physical layer protection (e.g. SONET Bi-Directional Line Switched Ring (BLSR)), a VPG protection holdoff function is employed at the VPG protection selector. A technical advantage of this protection switching invention is that it provides extremely fast protection switching of an extremely large number of ATM virtual connections.

Abstract: A gyricon or twisting-particle display based on nonspheroidal (e.g., substantially cylindrical) optically anisotropic particles disposed in a substrate. The particles can be bichromal cylinders, preferably aligned parallel to one another and packed close together in a monolayer. A rotatable disposition of each particle is achievable while the particle is thus disposed in the substrate; for example, the particles can already be rotatable in the substrate, or can be rendered rotatable in the substrate by a nondestructive operation performed on the-substrate. In particular, the substrate can be made up of an elastomer that is expanded by application of a fluid thereto so as to render the particles rotatable therein. A particle, when in its rotatable disposition, is not attached to the substrate. The close-packed monolayer configuration of particles provides excellent brightness characteristics and relative ease of manufacture as compared with certain other high-brightness gyricon displays. The substrate containing the cylinders can be fabricated with the swelled-elastomer techniques known from spherical-particle gyricon displays, with a simple agitation process step being used to align the cylinders within the sheeting material. Techniques for fabricating the cylinders are also disclosed.

Granted: 2004-09-14
Abstract: The invention concerns a mechanical loom comprising a weaving reed (8) and a weft thread guide device (32) which are interconnected so as to pivot between an insertion position and a stop position.     In order to insert the weft, there are provided a stationary weft-insertion device (14) with at least one blower nozzle (22) for inserting a weft thread (38) into the guide duct (36), as well as a thread clamp (16) and scissors (15). The thread clamp (16) is coupled with the weaving reed in order to clamp an inserted weft thread (38) and convey it synchronously with the guide duct (36) from the insertion position to the stop position. The scissors (15) are arranged downstream of the thread clamp (16) in the stop direction in order to cut off the weft thread immediately after it has been clamped. Since the insertion device is stationary and the thread clamp and scissors are operatively associated with the weaving reed, control of the loom is simplified such that up to sixteen different weft threads can be inserted.

Abstract: An apparatus for fabricating bichromal balls includes a means for fabricating droplets from electrically conductive hardenable liquids. The liquids have different colors. A forward end of the hardenable liquids becomes unstable and breaks up into the droplets. Each droplet includes hemispheres of different colors. An RF signal generator produces electrical pulses which increase the instability of the forward end of the hardenable liquids.      A capacitance in the conductive liquids causes current to flow from the signal generator to the hardenable liquids.      A diameter of the droplets is reduced to form substantially spherical balls. Each of the balls includes hemispheres of different colors. The bichromal balls are collected.

Title: Flow control of frame based data over a synchronous digital network
Inventor: SHIELDS JAMES
IPC: H04L12/413
Filed: 1999-09-02
Granted: 2005-08-16
Abstract: A transmission apparatus and a method for operating the apparatus comprises means for controlling flow of frame based data transmitted from a local frame based data channel interface over a synchronous digital network. The method of operation comprises the transmitter receiving frame based data at a first rate whereafter a buffer is configured to receive the frame based data. A data amount threshold level for the buffer is predetermined whereafter, with respect to the threshold level, an amount of transmitted frame based data that has been received is monitored. In response to monitoring the amount of data received, a signal, in the form of a pause frame, is generated wherein the signal is configurable to adapt the rate of transmission from the frame based data channel interface. Working in conjunction with the transmission means there is also provided a receiver for controlling flow of frame based data, received from a synchronous digital network, to a frame based data channel interface. The receiver is configured to receive the frame based data at a first rate whereafter a buffer is configured to receive the frame based data. Upon pre-determining a data amount threshold level for the buffer an amount of frame based data received is monitored with respect to the threshold level.  In response to monitoring the amount of data received, a signal is generated in the form of a pause frame, wherein the pause frame signal is configurable to adapt the first transmission rate of the frame based data over the synchronous digital network to a second rate. In this way, the rate of transmission from a local Ethernet switch may be controlled and the rate of receipt of Ethernet based frame data from a synchronous digital network may be controlled. In the latter case pause frames may be incorporated into one or more synchronous digital hierarchy virtual containers.
