Abstract: The present invention disclosed a method for operating a software radio receiver. Said method comprises receiving a radio signal, determining a signal quality of said radio signal, selecting a suitable algorithm for a function in the receiver in accordance with said determined signal quality and applying said selected algorithm to the radio signal.

Abstract: A fluid control valve 1 comprising a valve body 2 having a central bore 4 provided with a plurality of radial apertures defining inlet and outlet ports 5,6,7, and a spool slidably mounted within the central bore for axial movement therein to provide selective fluid communication between selected pairs or groups of the inlet and outlet ports, wherein at least one annular groove 14a,14b,14c is formed in an outer periphery of the valve body in the region of one of said radial apertures, a filter 12 being provided in said at least one annular groove, the filter comprising a perforated plate or membrane formed into a cylindrical shape and located in the annular bore, the perforated plate being held in place in the groove by retaining means 16, wherein the retaining means 16 comprises an elongate resilient member located around the outer periphery of the perforated plate and adapted to apply a compressive biasing force against the plate, free ends of the elongate resilient member extending substantially tangential

Abstract: A method and system for combining short range communication and long range communication for traffic related applications is presented. In one example, a central server is equipped and configured to receive information via long range communication from one or more individual traffic objects, analyze the received information to determine the short range communication needs, if any, between an identified subset of traffic objects and then initiate short range communication between the traffic objects in the identified subset of traffic objects.

Abstract: The invention relates to a processing of a data word in a plurality of processing cycles. In order to improve the efficiency of the processing, the data word is divided for each cycle into a plurality of successive data blocks. The blocks are shifted by one block from one cycle to the next. In each of the cycles, each of the successive blocks is processed in sequence. In the first cycle, the processing results for successive blocks are moreover stored in a memory at memory addresses which change uniformly from one processing result to the next. In each subsequent processing cycle, the processing results for the successive blocks of the subsequent cycle are combined with processing results stored in the memory during a preceding cycle at memory addresses which change uniformly from one processing result in the subsequent cycle to the next.
