Abstract: Concepts and technologies disclosed herein for routing information through a blocking splitter-combiner switching network. A control system can execute a control module and communicates with one or more satellites. The control module can generate and transmit control data for controlling traffic or other communication over a channelizer at a satellite. A satellite network operator can generate a cross-connection request that is processed by the satellite control at a ground control station or a processor on the satellite. The cross-connection requests a cross-connection for transmitting satellite user information within or across satellite beams. The control system can attempt to identify an output channel. If the output channel is found, the connection can be established. If the output channel is not found, the control system can execute various operations to partially or fully preempt other communications to accommodate a higher priority connection request.

Abstract: The system contains an RF demodulator. A packet aggregation switching device is in communication with the RF demodulator. At least one packet processing engine is in communication with the RF demodulator. The packet aggregation switching device controls communication between the RF demodulator and the packet processing engine. An RF modulator may also be in communication with the packet processing engine along an egress path. The packet aggregation switching device may output traffic into the egress path.

Abstract: A method and apparatus are provided for discarding a priority fair share of traffic of network connections. In one example, the method receives traffic of at least a particular network connection. A portion of a fixed buffer allocation space is filled with traffic of the particular network connection, wherein a buffer in the fixed buffer allocation space is associated with a fixed buffer allocation queue identification. A portion of a prioritized fair share buffer space is filled with traffic of the particular network connection, wherein a buffer in the prioritized fair share buffer space is associated with a priority fair share queue identification. A portion of the lowest priority traffic of the network connections is discarded.

Abstract: The present invention is a shared buffer architecture that dynamically allocates buffer size to each of multiple sources depending on buffer pool utilization, estimated per-connection offered load, and the total number of connection established within a given class of service. When the buffer pool is almost empty, each source is allocated a large buffer space, proportional to its estimated offered load. When the buffer pool is more full each source is allocated a reduced buffer space, while maintaining the proportional weighting relationship. The invention keeps track of the amount of input per source and dynamically allocates a proportionate amount of buffer space in the buffer memory for that source. The dynamic allocation is made as a function of the fullness of the memory allocation for all sources. Additionally, thresholds are modulated dynamically as the number of established connections within a given class modulates, providing a predictive aspect to the system, with respect to congestion control.

Abstract: A bi-modal network connection device provides a high level of adaptability to changing connection-level loading patterns without sacrificing speed and configurability. The device can function in both a static mode and a traffic-adaptive mode. Benefits include the ability to provide high buffer utilization and throughput in ATM networks which either have very dynamic connection-level statistics or have poorly understood traffic characterization, plus the ability to assure users of minimal latency delays if desired.

Abstract: A differential assembly including a rotatable casing, first and second axially moveable side gears disposed within the casing, at least one pinion gear disposed within the casing and intermeshed with the side gears, a cone clutch operatively coupled to the first side gear, the cone clutch being frictionally coupled to the casing in response to being exposed to a magnetic field, and a disc clutch having at least one clutch disc operatively coupled to the second side gear in response to axial movement of the second side gear.

Abstract: A dual rotor disc brake utilizing spot or segment type friction pads. The rotors and friction pads are axially movable for contact by adjacent ones thereof and major portions of the rotors rotate free of contact with the friction pads.

Abstract: A fluid motor moves a lever to turn a power screw mounted for rotation by a pair of axially spaced bushings. External threads on the power screw engage internal threads on an actuator and slide or translate the actuator and a piston in a brake-applying direction. A spring moves the piston in the opposite direction to a rest position. A cap fits over a medial flange of the power screw and has a spline connection with the actuator to prevent rotation of the actuator. Four bolts connect the fluid motor mounting bracket and the cap to a caliper which slides on parallel pins fixed to a torque plate secured to a vehicle axle.

Abstract: The invention relates to a friction pad for a disc brake and a disc brake assembly in which the friction pads are slidably supported by tabs extending radially outward of the friction pad backing plates on spaced, axially extending, radially converging edges of an aperture provided to the disc brake caliper. The friction pad includes an abutment surface adjacent each edge of the tab to locate the friction pad relative to an inner surface of the caliper.
