Abstract: A network node preprocesses Closed User Group (CUG) member rules and network configuration information available to the node during a configuration phase of the network preceding an operational phase in which calls are placed among the users. The preprocessing stores the information about the CUG membership of network users into a preprocessed CUG information table directly associated with user addresses. CUG membership of some attached users is ambiguous at configuration time if there exists a CUG member rule that is more specific than a prefix configured on the node with which the addresses of such users begin. For such users, CUG membership is determined at call time. The node determines at configuration time whether the CUG membership information concerning users whose addresses begin with each prefix configured on the node is ambiguous, and for those prefixes for which user CUG membership is ambiguous an associated indicator is set.

Abstract: A method and apparatus is disclosed for allocating bandwidth within a network switch having a plurality of input ports coupled to a plurality of output ports through a switch fabric to assure that a minimum bandwidth is allocated for predetermined scheduling lists. A switch allocation table is provided for each of a plurality of input ports. Each switch allocation table is organized as a circular table which is sequentially indexed via an associated index counter. Respective entries in the switch allocation table comprise scheduling list numbers which serve to identify cells requiring switch bandwidth. The respective index counters are synchronized such that all switch allocation tables have a corresponding entry selected. The amount of bandwidth and delay through the network switch is controlled for each of the scheduling lists based upon the number and spacing of entries in the respective switch allocation table.

Abstract: An apparatus and a method are disclosed for arbitrating between streams of ATM cells, or sources for a connection, on multiple input port processors vying for an opportunity to be transmitted as a fixed bandwidth, or allocated, connection on a single output port through a network switch. The network switch maintains a plurality of input port processors, at least one output port, and input and output buffers associated with the respective input and output ports. Streams of ATM cells enter the network switch as sources for a connection through the multiple input port processors and are buffered in the input buffers. The ATM cells are then routed from the input buffers to an output buffer in the output port. The network switch also provides a multipoint topology controller (MTC) and a bandwidth arbiter (BA) for performing the arbitration.

Abstract: A motor controller controls a motor's rotational speed using sensed back electromagnetic force (back EMF) of the motor. The sensed back EMF is presumed to contain an error component caused by series resistance in the motor coil. A velocity sense signal is continually generated representing the sum of the measured back EMF and an error-cancelling quantity equal to the current in the coil scaled according to a gain-control signal stored in the controller. During the first part of a calibration operation, the coil current is set to zero until a time T.sub.1 at which the coil current is substantially zero and the motor velocity is substantially constant. The value of the velocity sense signal is stored at the time T.sub.1, this value representing the zero-current back EMF of the coil.

Abstract: A fiber preform is made solely from a deformable base fiber structure that s initially in the form of a plane plate constituted by superposed two-dimensional fiber plies bonded together by needling. Cuts and/or splits are formed in the base fiber structure, and the preform is made from the cut and/or split base fiber structure by making use of its ability to be deformed. The structural part is obtained by densifying the preform using a material that constitutes a composite material matrix. It is possible to use a single fiber structure plate which is deformed with the help of splits or cuts so as to obtain the desired preform and in which continuity of the base fiber structure is preserved, or else a plurality of base fiber structure plates can be used which are assembled together by mutual interfitting via the splits or cuts, by deforming at least one of the plates.

Abstract: A class of murine monoclonal antibodies that is capable of stimulating megakaryocytopoiesis in vitro has been raised against human megakaryocytic cells. The monoclonal antibody BAH-1 specifically recognizes and demonstrates agonist activity against the c-Mpl receptor on the megakaryocytic cell surface. In therapeutic applications, the BAH-1 and M4 monoclonal antibodies identified to date and similar antibodies (or active portions and chimeric combinations thereof) can stimulate proliferation of primary bone marrow megakaryocytes. Thus, the antibodies of the invention can be used to prepare a composition for treating, e.g., thrombocytopenia. A typical composition comprises a therapeutically effective amount of the BAH-1 monoclonal antibody in association with a pharmaceutically acceptable carrier vehicle.

Abstract: A method and cache management for a bridge or bridge/router providing high-speed, flexible address cache management. The unit maintains a network address cache and an age table, searches the cache for layer 2 and layer 3 addresses from received frame headers, and returns address search results. The unit includes an interface permitting processor manipulation of the cache and age table, and supports a 4-way set associative cache to store the network addresses. A plurality of functions implemented in hardware enables software manipulation of the associated cache. Four cache operating modes are selectable. The unit can identify and select destination ports within a Load Balanced Port Group for frame forwarding. The unit utilizes Virtual LAN identification in conjunction with a MAC address for lookup in the cache. A cyclic redundancy code for each address to be looked up in the cache is used as an index into the cache. If a cache thrash rate exceeds a predetermined threshold, CRC table values can be rewritten.

Abstract: A system is disclosed for eliminating cell loss through the use of flow control of both allocated and dynamic bandwidth. When output buffers in the switch become filled to a predetermined threshold level a feedback message is provided to input buffers to prevent transmission of cells from the input buffers to the output buffers. In order to provide connection and traffic type isolation the buffers are grouped into queues and flow control may be implemented on a per queue basis. The feedback message is a digital signal including an ACCEPT/REJECT message and a NO-OP/XOFF message. An XOFF message can be received while transmitting via allocated bandwidth or dynamic bandwidth. In particular, an XOFF (allocated) message may be received with regard to allocated bandwidth and an XOFF (dynamic) message may be received with regard to dynamic bandwidth. When ACCEPT is received by the requesting input queue the cell is transferred to the output queue.

Abstract: Logic circuits are employed in a telecommunications bridge/router device to examine a received frame to determine which VLAN, if any, the frame is associated with. The protocol type, receive port identification, and receive VLAN tag are employed to determine the transmit port identification and transmit VLAN tag. A predefined table indicates which ports within the bridge/router are associated with the VLAN. The frame is excluded from transmission through the ports that are not associated with members of the respective the VLAN.

Abstract: An apparatus for detecting the presence of a wafer cassette, or pod, resting on an arrangement of pins allows cassette detection without interfering with insertion of a robotic paddle arm beneath the cassette to remove it for transport. A cassette resides on an arrangement of beveled pins which mate with corresponding receptacles on the underside. Pins supporting the cassette have a spring biased, hollow outer cylinder coaxially mounted around a center post. A cassette placed on the pins displaces the outer cylinder downward a sufficient distance to trigger a sensor. Upon removal of the cassette, the outer cylinder is displaced upwards, resetting the sensor.
