Abstract: Articles are magnetically tagged by a spatial distribution of passive magnetic elements. Each such magnetic element comprises a layer of soft magnetic material characterised by high permeability, low coercivity and a non-linear B-H characteristic, and formed as a discrete region of such material. Each such magnetic element also has at least one second layer of magnetic material capable of being permanently magnetised at least in a region adjacent the first layer to provide a magnetic bias for the magnetic element. The bias of individual such magnetic elements in the spatial distribution and the particular spatial nature of the distribution enables the article to be magnetically encoded.

Abstract: A method, apparatus, system, and signal-bearing medium that in an embodiment detect an event that will cause idle cycles in the processor and issue diagnostic instructions to the processor during the cycles that would be idle. In another embodiment, the processor is periodically interrupted and diagnostic instructions are issued to the processor, where the diagnostic instructions are selected based on a history of activity at the processor and a log of previous errors at the processor. In this way, errors may be detected at the processor without undue cost and impact on performance.

Abstract: A drive assembly for a combine head includes a hub and a bearing received over a portion of the hub. The bearing defines a rotational axis of the hub. A plane passes radially through the bearing relative to the axis. A sprocket is coupled to the hub and is coaxial with the bearing. The sprocket has a plurality of teeth located around a perimeter of the sprocket, the plurality of teeth being located so that the plane passes radially through the plurality of teeth.

Abstract: Methods and apparatus implementing and using techniques for scaling a character having stems. A character including stems and having an associated output resolution and an associated bit depth can be received. The counters defined by the stems can be grouped into one or more chains of counters. The stems of the character can be aligned based on a stem alignment policy while the chains of counters are balanced based on the output resolution. A pixel map can be created at the output resolution and the output bit depth based on the aligned stems.

Abstract: A more efficient method of handling instructions in a computer processor, by associating resource fields with respective program instructions wherein the resource fields indicate which of the processor hardware resources are required to carry out the program instructions, calculating resource requirements for merging two or more program instructions based on their resource fields, and determining resource availability for simultaneously executing the merged program instructions based on the calculated resource requirements. Resource vectors indicative of the required resource may be encoded into the resource fields, and the resource fields decoded at a later stage to derive the resource vectors. The resource fields can be stored in the instruction cache associated with the respective program instructions. The processor may operate in a simultaneous multithreading mode with different program instructions being part of different hardware threads.

Abstract: Techniques are described for eliminating the potential continuity errors in fluid connection devices, such as tubes, which can arise in complex systems where many tubes are used. The techniques are based upon the use of ultrasound, light or pressure waves being transmitted along the connecting device using a transmitter and a receiver at either end. Methods are described to cover the external coupling of the transmitter and/or the receiver into the tubing thereby eliminating the need to compromise the connection. The described apparatus can be external to the system or integrated within it. The potential to carry information along the connection device is also disclosed.

Abstract: A processor having the capability to dispatch multiple parallel operations, including multiple load operations, accesses a cache which is divided into banks. Each bank supports a limited number of simultaneous read and write access operations. A bank prediction field is associated with each memory access operation. Memory access operations are selected for dispatch so that they are predicted to be non-conflicting. Preferably, the processor automatically maintains a bank predict value based on previous bank accesses, and a confirmation value indicating a degree of confidence in the bank prediction. The confirmation value is preferably an up-or-down counter which is incremented with each correct prediction and decremented with each incorrect prediction.

Abstract: The present invention extends to configuring detection zones in a traffic monitoring system and to association of detection zones with corresponding traffic signal phases. One or more sensors detect targets within a roadway intersection. The sensors integrate acquired sensor data for the targets into track files. The track files are subsequently used to identify common target paths. A histogram is used to identify common target positions for stationary targets. From the common target positions and the common target paths detection zones are configured. Detection zones are associated with traffic signal phases so that specific detections can be created. Lane boundaries within the roadway intersection are inferred from the common target paths. Permanent stationary target locations are identified from the common target positions.

Abstract: A method, apparatus, system, and signal-bearing medium that in an embodiment detect an error, disable selected functions of a computer system via inhibit switches in response to the error, issue a set of diagnostic instructions to a processor, and incrementally enable the selected functions until the error is reproduced. In this way, the source of the error may be determined.

Abstract: A high-frequency compound instruction mechanism and method allows performing a common compare immediate function before an add function has completed, thereby reducing the number of cycles to perform the add-compare function. By increasing the speed of performing the add-compare function, a branch mispredict signal may be provided to an instruction pipeline before data registers are affected by the pipelined instructions. The compound instruction mechanism of the preferred embodiments may be implemented within space that is primarily unused within arithmetic logic units, resulting in an implementation that only marginally increases space requirements on an integrated circuit.

Abstract: A closed system, spikeless, positive-flow valve device includes a body defining an internal cavity. At the proximal end of the body is an opening which is preferably sufficiently large to receive an ANSI standard tip of a medical implement. The valve includes a plastic, resilient silicon seal which fills the upper cavity and opening with an oval seal cap having a slit. The opening presses the oval seal cap to keep the slit closed in the decompressed state. The slit opens as the nose of the medical implement compresses the seal into the cavity and the seal cap is free from the opening. The housing also includes a fluid space which facilitates fluid flow between the medical implement and a catheter tip.

Abstract: A multiple parallel pipeline digital processing apparatus has the capability to substitute a second pipeline for a first in the event that a failure is detected in the first pipeline. Preferably, a redundant pipeline is shared by multiple primary pipelines. Preferably, the pipelines are located physically adjacent one another in an array. A pipeline failure causes data to be shifted one position within the array of pipelines, to by-pass the failing pipeline, so that each pipeline has only two sources of data, a primary and an alternate. Preferably, selection logic controlling the selection between a primary and alternate source of pipeline data is integrated with other pipeline operand selection logic.

A failure of a shareable unit in one processor causes that processor to share the corresponding unit in another processor on the same chip. Preferably, a functional unit is shared on a cycle interleaved basis.
