A memory device that includes an input interface that receives instructions and input data on a first plurality of serial links. The memory device includes a memory block having a plurality of banks, wherein each of the banks has a plurality of memory cells, and wherein the memory block has multiple ports. An output interface provides data on a second plurality of serial links. A cache coupled to the IO interface and to the plurality of banks, stores write data designated for a given memory cell location when the given memory cell location is currently being accessed, thereby avoiding a collision. Memory device includes one or more memory access controllers (MACs) coupled to the memory block and one or more arithmetic logic units (ALUs) coupled to the MACs. The ALUs perform one or more operations on data prior to the data being transmitted out of the IC via the IO, such as read/modify/write or statistics or traffic management functions, thereby reducing congestion on the serial links and offloading appropriate operations from the host to the memory device.

A session transfer module of a session server provides the capability to a user to direct a transfer of an on-going session from one device to another device while maintaining the session. The session transfer module is invoked by a user in a way consistent with the user interface of the client application, including by a graphical user command, a command line prompt, or a voice command. The client provides a selection of possible devices that may receive the redirected session. The session transfer module receives the selected device with the session redirect command over a communication network. The communication network may be wired (e.g., public switched telephone network (“PSTN”), Internet, etc.,) a wireless network (e.g., digital telephone network, pager network, etc.,) or a combination of the wired and wireless networks. The session transfer module may be configured to discontinue the session with the current device and to block any subsequent messages of the transferring session from reaching the device. The session transfer module may be further configured to access a device profile from a device profile database to convert the blocked messages into a format compatible to the format and/or modality of the redirected device. The session transfer module may be further configured to push the session to the redirected device in response to an activation (e.g., log-on) of the redirected device by the user. Alternatively, the session transfer module may be further configured to push the session back to the device in response to a time-out in the activation of the redirected device.

A method (10) for injecting ammonia (NH3) into exhaust gas upstream of a catalyst of an aftertreatment system includes the steps of determining whether a regeneration event is imminent (14) on the basis of predetermined parameters, and determining whether dosing parameters are met (22). The method (10) further includes the steps of calculating an amount of NH3 to fill the catalyst (18) and adjusting a quantity of NH3 dosed (22) before the regeneration event occurs.

A mixing device and method for a diesel exhaust system is disclosed having a chamber, a mixer within the chamber, and an injection tube supported on the mixer within the chamber. The mixer is positioned within the chamber adjacent an inlet and includes a plurality of angled blades to effect turbulent flow in a diesel exhaust stream entering the chamber through the inlet. The injection tube includes a plurality of injection points (e.g., openings) for discharging a reagent, such as gaseous ammonia (NH3), into the exhaust stream. The injection tube is curved, and more specifically it is coiled with the injection points spread along the length of the tube in order to deliver reagent across a section of the chamber perpendicular to the exhaust stream flow.

The present invention extends to methods, systems, and computer program products for monitoring signalized traffic flow. A processor in a sensor system or traffic controller interface estimates the time-of-arrival and other traffic flow estimates of one or more vehicles to an intersection stop bar, while the vehicles are within a continuous range of one or more transducers view of the sensor system. A level of efficiency and safety within the signalized traffic flow is estimated by the sensor system based upon one or more of the estimated time-of-arrival and other flow variables estimates and then communicated to the control unit of the traffic signal system. Other flow estimates for each vehicle include but are not limited to: position relative to the stop bar, lane position, velocity, acceleration, time headway and classification.

Disclosed is an interface between a drug delivery cassette and a medical effector system. The cassette may be mounted to the medical effector system in such a way that a fluid tube located on the cassette is positioned adjacent to a pump located on the medical effector system. The medical effector system may purge the fluid line of air by activating the pump and forcing fluid through the fluid line until a sensor positioned to monitor the fluid line indicates that fluid and not air is present in the tube. To prevent air purging of the fluid tube when connected to the patient, the medical effector system prohibits air purging unless the drug delivery end portion of the fluid tube is in a designated storage site located on the cassette. This is accomplished with a position sensor at the storage site that monitors the position of the fluid tube.
摘要:
An engine system for a combustion engine that has an intake manifold and an exhaust manifold has a turbine having a turbine inlet for receiving exhaust gas and a turbine outlet for discharging exhaust gas, and a diesel particulate filter (DPF) having a DPF inlet in flow-communication with the exhaust manifold and a DPF outlet in flow-communication with the turbine inlet. The exhaust at the exhaust manifold has a sufficiently high temperature to maintain passive regeneration of the DPF during normal operating conditions. If the engine system includes an exhaust gas recirculation (EGR) system, the EGR inlet is in flow-communication with the DPF outlet, and an EGR outlet is in flow-communication with the intake manifold. High pressure, high temperature, filtered EGR gas is available for EGR recirculation.

摘要:
A content matching engine (CME) uses a content addressable memory (CAM) array that stores a plurality of strings in separate entries. The strings define one or more rules to be matched. The strings of each rule are linked, thereby providing a required order. The strings of each rule can be linked by per-entry counters associated with each string, or by a state machine. The strings in the CAM array are compared with a packet, which is shifted one symbol at a time (because the strings can start on any boundary). When the CAM detects a match, the CAM skips over the string that resulted in the match, thereby preventing erroneous matches. The CAM allows parallel matching to be performed for multiple rules. If the contents of a packet match all of the strings of a rule, in order, then the CME asserts a match/index signal that identifies the matched rule.
