An engine control apparatus is disclosed for determining crankshaft position and engine phase of an internal combustion engine (10) through monitoring intake air pressure fluctuations (120). The opening of the intake valve (44) is mechanically linked to the crankshaft position of an engine. When the intake valve (44) opens it creates air pressure fluctuations in the air induction system (14) of the engine (10). The control apparatus is configured to determine intake air pressure fluctuations indicative of an intake air event (100 to 110) and thus a particular crankshaft position, and their corresponding period of the engine cycle. The controller then uses this information to determine crankshaft speed and position for the purpose of fuel injection and ignition timing of the internal combustion engine. Engine phase is also determined on four-stroke engines. The engine may also include a crankshaft position sensor in combination with monitoring intake air pressure fluctuations to increase resolution in determination of crankshaft position.

An apparatus is described that facilitates network security and network traffic monitoring through processing of network traffic in accordance with provisioned rules and policies. The apparatus includes a set of microcode controlled state machines, each of which includes a computation kernel operating in accordance with microcode stored in a control store. A distribution circuit routes individual network traffic segments derived from input network traffic to the set of microcode controlled state machines, so that at least one of the microcode controlled state machines applies a rule encoded in the microcode to the individual network traffic segments to produce modification instructions. A circuit performs a modification of the input network traffic based on the modification instructions from the at least one microcode controlled state machine to produce output network traffic. Advantageously, the apparatus provides an architectural framework well suited to a low cost, high speed, robust implementation of flexible, advanced network security and monitoring features, traffic management, and integration of devices within a system.

An apparatus is described that performs prioritized matching through processing of network traffic in accordance with provisioned rules and policies. The apparatus includes a plurality of microcode controlled state machines, and a distribution circuit that routes input data to the plurality of microcode controlled state machines, such that the plurality of microcode controlled state machines apply rules to the input data to determine matches and produce priority indicators, wherein each match has an associated priority indicator. At least one of the matches is selected based on the priority indicators. Advantageously, the apparatus provides an architectural framework well suited to a low cost, high speed, robust implementation of flexible, advanced network security and monitoring features and network traffic analysis.

The present invention relates to a ground milling machine, particularly a road milling machine, comprising a machine frame supported by travelling devices, a drive engine and a milling device arranged in a milling drum box, the milling drum box comprising a stripping plate which is height-adjustable by means of at least a first and a second actuator. Further, the present invention relates to a method for adjusting a stripping plate of a milling drum box of a ground milling machine, particularly a road milling machine. For the purpose of a reliable adjustment of the stripping plate, the present invention proposes using a monitoring device for detecting the adjustment of a first actuator and a control device for controlling the adjustment of a second actuator depending on the adjustment of the first actuator.

The invention provides, in one aspect, a virtual processor that includes one or more virtual processing units. These virtual processing units execute on one or more processors, and each virtual processing unit executes one or more processes or threads (collectively, “threads”). While the threads may be constrained to executing throughout their respective lifetimes on the same virtual processing units, they need not be. An event delivery mechanism associates events with respective threads and notifies those threads when the events occur, regardless of which virtual processing unit and/or processor the threads happen to be executing on at the time. The invention provides, in other aspects, virtual and/or digital data processors with improved dataflow-based synchronization. A process or thread (collectively, again, “thread”) executing withing such processor can execute a memory instruction (e.g., and “Empty” or other memory-consumer instruction) that permits the thread to wait on the availability of data generated, e.g., by another thread and to transparently wake up when that other thread makes the data available (e.g, by execution of a “Fill” or other memory-producer instruction).

The invention provides a three-dimensional object fusion feature representation method based on multi-modal feature fusion. According to the method, the feature representation of a three-dimensional model in three modals is meticulously realized and reproduced, namely, multi-view feature representation, point cloud feature representation and grid feature representation of the three-dimensional model. Multi-modal three-dimensional data is processed, enhanced and fused, and fusion feature representation of a three-dimensional object is extracted on the basis. According to the invention, excellent multi-modal information fusion can be realized, and more robust three-dimensional model feature representation is realized to be used for other three-dimensional object tasks.

An anti-jamming system includes a tunable negative jamming signal feedback loop for feedback suppression of a received jamming signal. The system includes a zero IF phase locked loop (PLL) jamming signal receiver having a synchronous demodulator and a phase detector. A VCO is included in the PLL, as well as a phase detector and a loop filter. A replica jamming signal generator includes a tracking modulator with a baseband signal input coupled to an output of a synchronous demodulator in the receiver and a carrier input provided by the VCO. An output of the tracking modulator is negatively fed back to the input of the receiver to suppress the jamming signal in the received input.

A receiver configuration for a control unit in a vehicle having a voltage generator for generating a synchronization pulse, which includes a first voltage source, a current source and a current sink, the voltage generator generating the synchronization pulse within predefined specification limits having a predefined shape and a predefined time behavior, and the receiver configuration outputting the synchronization pulse for synchronizing a signal transmission via a databus to at least one sensor. A method is also provided for generating a synchronization pulse. The voltage generator generates the synchronization pulse via the current source and the current sink by charging and/or discharging a bus load essentially as a sinusoidal oscillation.
