摘要： A radar indicator comprising a source of radar image signals having a first (r,.theta.) format and a digital scan converter responsive to the radar image signals for converting the radar image signals from the first format to digital radar image signals having a second (X-Y) format. The digital scan converter includes an image memory for supplying the digital radar image signals having the second (X-Y) format. A source of external video image signals having the second format, including video synchronization signals is provided. A synchronization signal stripper and clock signal generator circuit is responsive to the video synchronization signals of the external video image signals for generating a clock signal synchronized with the synchronization signals of the external video image signals. The clock signal is applied to the image memory of the digital scan converter for causing controlled read-out of the digital radar image signals in a manner synchronized with the image signals of the source of external video image signal. Video processing circuitry responsive to the synchronized digital radar image signals develop a radar video signal from the synchronized radar image signals, and a video mixer circuit mixes in a controlled manner the external video image signal with the synchronized radar video signals. The mixed external video images with the radar video images are subsequently displayed.

摘要： A method of calibrating detectors in a detector ring of a PET scanner, each detector including a plurality of crystals, the PET scanner having a field of view, is disclosed. The method comprises collecting timing data indicative of coincidence events occurring between each pair of crystals within the field of view. The method further comprises determining a detector adjustment value for each detector, determining a crystal adjustment value for each crystal in each detector, and discretizing the crystal adjustment value for each crystal to produce a discretized crystal adjustment value for each crystal. Lastly, the method comprises calibrating each detector by applying the discretized crystal adjustment value for each crystal in each detector to the collected timing data indicative of coincidence events.

摘要： A PET scanner contains a positron emission event qualifier which prevents noise from being misinterpreted as such an event. A radiation detector signal indicates the intensity and duration of sensed gamma radiation. A comparator produces an intermediate signal when the radiation detector signal exceeds a predetermined threshold. A delay line delays the intermediate signal by an interval of time and blocks any pulses in the intermediate signal which are shorter than this interval. Typical noise in the intermediate signal is shorter in duration than this interval of time.

摘要： A clip is disclosed herein which is composed of a resilient material and comprises a body having the following elements as in a relaxed state: opposing first and second ends, of which the first end is open to define a first slot, and the second end is closed; a first aperture adjacent to and communicating with the first slot, the first slot having a width less than the diameter of the first aperture; a second aperture adjacent to the second end; and a second slot extending between and communicating with the first and second apertures, the second slot having a width less than the respective diameters of the first and second apertures. The body of the clip is capable of deformation to temporarily increase the widths of the first and second slots for (i) receiving a pair of elongated member portions (i.e. electric cord portions) in respective first and second apertures, and for (ii) removing the clip from such elongated member portions.

摘要： Sequences of items may be maintained using ordered locks. These items may correspond to anything, but using ordered locks to maintain sequences of packets, especially for maintaining requisite packet orderings when distributing packets to be processed to different packet processing engines, may be particularly useful. For example, in response to a particular packet processing engine completing processing of a particular packet, a gather instruction is attached to the particular identifier of a particular ordered lock associated with the particular packet. If no longer needed for further processing, the packet processing engine is immediately released to be able to process another packet or perform another function. The gather instruction is typically performed in response to the particular ordered lock being acquired by the particular identifier, with the gather instruction causing the processed particular packet to be sent.

摘要： An x-ray alignment and measurement process including an x-ray source and a detection array. The detection array allows for the taking of images having a precisely known pixel size and location. Disposed between the x-ray source and the detection array is an object having a known size or position. The object is then imaged and the location and size of the object on the image can be determined and compared to the actual size or location. The calculation is performed on the multiple pixels in the image to mathematically determine the remaining unknown object location or size. For alignment purposes, any error in the location or size of the object can thus be corrected.

摘要： The present invention provides a network multithreaded processor, such as a network processor, including a thread interleaver that implements fine-grained thread decisions to avoid underutilization of instruction execution resources in spite of large communication latencies. In an upper pipeline, an instruction unit determines an-instruction fetch sequence responsive to an instruction queue depth on a per thread basis. In a lower pipeline, a thread interleaver determines a thread interleave sequence responsive to thread conditions including thread latency conditions. The thread interleaver selects threads using a two-level round robin arbitration. Thread latency signals are active responsive to thread latencies such as thread stalls, cache misses, and interlocks. During the subsequent one or more clock cycles, the thread is ineligible for arbitration. In one embodiment, other thread conditions affect selection decisions such as local priority, global stalls, and late stalls.
摘要翻译：本发明提供了一种诸如网络处理器的网络多线程处理器，其包括线程交织器，其执行细粒度线程决定以避免指令执行资源的不充分利用，尽管具有大的通信延迟。在上部流水线中，指令单元响应于每个线程上的指令队列深度来确定指令获取序列。在较低流水线中，线程交织器响应于包括线程等待时间条件的线程状况来确定线程交织序列。线程交织器使用两级循环仲裁来选择线程。线程延迟信号响应于线程延迟（如线程停止，高速缓存未命中和互锁）而有效。在随后的一个或多个时钟周期中，线程不符合仲裁规则。在一个实施例中，其他线程条件影响选择决策，例如本地优先级，全局档位和延迟档。
