摘要： A system for applying radiation therapy includes a radiation source for emitting a radiation beam and includes redundant treatment field-defining arrays for shaping the radiation beam. The radiation beam is initially shaped by a multileaf collimator having a side-by-side arrangement of leaf pairs. The leaves are individually manipulable to define apertures between the leaves of a pair. Thus, the contour of an irregular treatment field can be precisely defined. The second field-defining array includes field-defining members that are individually connected to corresponding leaves of the multileaf collimator. Preferably, the connections are mechanical linkages and there is a one-to-one correspondence of the field-defining members and the leaves. Adjustment of a leaf simultaneously adjusts a position of a corresponding field-defining member. Also in the preferred embodiment, the second array is contained within a conically shaped housing that provides beam guidance. As a result of the shape of the housing and the redundant arrays, healthy tissue is shielded during irradiation of a patient.

摘要： A turbine shroud segment includes a substrate and a coating layer having varying thickness. Various construction details are developed that provide minimal spalling of the coating layer during use of the shroud segment. In a particular embodiment, a shroud segment includes a coating layer that tapers towards the edges. The thickness tapers to a minimum thickness along the leading and trailing edges. Within the blade passing region of the shroud segment, the coating layer tapers towards the lateral edges to a thickness determined by the minimum thickness required for abrasive contact between the shroud segment and rotor blades. In another particular embodiment, the varying thickness of the coating layer is produced by forming the substrate with a concave surface, applying the coating, and subsequently machining back the coating layer to the desired dimensions.

摘要： A large diameter rotary drum has an open top and a floor in which are mounted a plurality of freely rotating sprockets having sharpened teeth. Wood wastes, large blocks, trimmings from shake mill operations, broken shakes and the like are deposited into the drum and are carried over the sprockets. The rolling action of the teeth on the wastes grinds the wastes to much smaller pieces which fall through openings around the sprockets and are carried away by a conveyor.

摘要： The invention provides a method and system for rapid access to one or more M-tries for responding to header information. The M-tries are stored in a plurality of memory banks, which are accessed in parallel to provide relatively greater access throughput. Parts of the M-tries that are (or are expected to be) frequently referenced are stored in multiple banks of the memory, to provide concurrent simultaneous access for those parts of the M-tries for parallel lookup of multiple routes. Regions of the multiple banks of the memory can be dynamically reallocated to provide improved access through-put to those multiple banks. The invention can be applied to routing decisions in response to destination addresses, to combinations of destination and source addresses (either for unicast or multicast routing), to access control decisions, to quality of service decisions, to accounting, and to other administrative processing in response to header information.

摘要： A system and a method are provided for intensity modulated radiation treatment. A field on a patient (544) for irradiation is first defined. A beam of radiation (530) is then provided. This beam (530) passing through an opening defined by a beam-shielding device (540, 542). In the preferred embodiment, the beam shielding device is a single jaw (540) and a single collimator section (542). Single jaw (540) and single collimator section (542) are moved in one direction at different velocities to vary the opening for radiation beam (530). Single jaw (540) and single collimator section (542) move without rotation to provide intensity modulated radiation treatment

摘要： A bus protocol technique removes the transaction used for posting indications of events to the host processor from the bus. The invention takes advantage of the fact that addresses typically on a high speed bus contain fewer bits than the entire bus width. Particularly, for a 32 bit bus, the 32 bit address space is not always necessary. The remaining bits on the bus are used for an encoded event tag. A bus transaction involves a first bus transfer which provides an address for writing or reading data, along with the event tag. The event tag is detected and decoded by the destination, and the event is posted to the processor which monitors and responds to events, in a manner which is synchronous with completion of the transaction. Thus, after the transaction on the bus, the message subject of the transaction is waiting in the memory, and notification of the event has occurred automatically and synchronously with completion of the transfer.
摘要翻译：总线协议技术从总线中去除用于向主机处理器发布事件的事件的事务。本发明利用了这样的事实，即通常在高速总线上的地址比整个总线宽度包含更少的位。特别地，对于32位总线，32位地址空间并不总是必需的。总线上的其余位用于编码事件标签。总线事务涉及第一个总线传输，其提供写入或读取数据的地址以及事件标签。由目的地检测和解码事件标签，并且以与事务完成同步的方式将事件发布到监视和响应事件的处理器。因此，在总线上的交易之后，事务的消息主体正在等待在存储器中，并且事件的通知已经自动并且与传送完成同步地发生。

摘要： A method of establishing coincidence between a field size of a light field used in a setup mode of a radiation system and a field size of a radiation field used in an operation mode of the system includes providing automatic adjustment of field-defining structure to compensate for differences in optical properties of the light and the radiation. A light beam passing through the field-defining structure typically exhibits greater scattering than an X-ray beam passing through the structure. For each of a number of different settings of the field-defining structure, the difference between the field sizes of the light and the radiation are determined and recorded. Then, for a particular desired field size, the field-defining structure can be automatically adjusted to provide compensation. In the preferred embodiment, the field-defining structure includes jaws of a collimator of a radiation system and the determination of field size differences of the light and the radiation occurs for each of various energy level settings of the radiation system.

摘要： A tooth for use in a comminuter roll comprises a roll of spring steel having a first end formed into a point or other abrading shape. The tooth is compressed upon insertion into a mounting hole in the roll and the inherent spring of the steel tends to force the tooth back to its original size, thereby creating forces on the interior of the mounting hole to form an interference fit that holds the tooth in place in the mounting hole. In a preferred embodiment, the tooth is formed of a roll of spring steel having a G-shaped cross section. This shape provides an opening through the length of the tooth and also leaves a solid piece in the center of the tooth to aid in tooth removal. A rod can be slipped through the lengthwise opening of the first tooth so that its end abuts the solid center portion of the second tooth that is colinearly mounted in the other end of the hole that the first tooth is mounted in. Tapping the rod will force the second tooth out of its hole without disturbing the first tooth. The steel piece can be cut either before or after rolling to form suitable abrading ends on the teeth and a back end of the tooth can be chamfered to make the tooth easier to insert in the hole of the roll.
摘要翻译：用于粉碎辊的牙齿包括一卷弹簧钢，其具有形成点或其它研磨形状的第一端。当插入到辊中的安装孔中时，齿被压缩，并且钢的固有弹簧倾向于迫使齿回到其原始尺寸，从而在安装孔的内部产生力以形成过盈配合，以保持齿就位于安装孔中。在优选实施例中，齿由具有G形横截面的弹簧钢卷形成。这种形状提供了穿过牙齿长度的开口，并且还在牙齿的中心留下了一块固体件，以帮助牙齿去除。杆可以穿过第一齿的纵向开口滑动，使得其端部邻接于与第一齿安装在孔的另一端中共线安装的第二齿的实心中心部分。敲击杆将迫使第二个牙齿从其孔中脱出而不会打扰第一颗牙齿。钢片可以在轧制之前或之后切割，以在齿上形成合适的研磨端，并且齿的后端可以倒角以使得齿更容易插入辊的孔中。

摘要： The present invention provides a mechanism whereby caching operations, such as prefetch and copyback operations, can be initiated by an external direct memory access (DMA) controller. This allows the DMA controller to govern the inclusion as well as exclusion of data from a processor cache in such as way as to avoid unnecessary cache faults, and to thereby improve system performance. Thus, the present invention effectively provides a synchronization mechanism between an external DMA controller and a processor cache.
摘要翻译：本发明提供了一种机制，其可以由外部直接存储器访问（DMA）控制器启动诸如预取和复制操作之类的高速缓存操作。这允许DMA控制器以诸如避免不必要的高速缓存故障的方式来管理来自处理器高速缓存的包含以及排除数据，从而提高系统性能。因此，本发明有效地提供了外部DMA控制器和处理器高速缓存之间的同步机制。
