    • The present invention provides an "alert" interface for a component which can be safely "hot-plugged/unplugged" to an "alert" interconnect of an electrically powered system. The alert interface has a mating edge which includes daughter precharge/ground connectors, a daughter (engage) waning connector, a number of daughter signal connectors and a daughter engage connector. The alert interconnect includes corresponding mother connectors. The respective connectors of the interconnect and the interface are arranged so that they mate in the following exemplary order when the interface is hot-plugged/unplugged to the interconnect: precharge/ground connectors, warning connectors, signal connectors and finally engage connectors. When the daughter (engage) warning connector mates with the mother warning connector, the component sends an "engage warning" signal to the powered system. Eventully, all the signal connectors mate followed by the engage connectors, enabling the component to send an "engaged" signal to the system indicating that all the signal connectors have completely mated. In accordance with another aspect of the invention, the component can also be safely "hot-unplugged" by first, substantially increasing the degree of recess of the daughter engage connector relative to the daughter signal connectors along the mating edge, and second, doubling the daughter engage connector to function as a daughter disengage warning connector.
    • 本发明提供了一种用于组件的“警报”界面,该组件可以安全地“热插拔”到电力系统的“警报”互连。 警报界面具有配合边缘,其包括女儿预充电/接地连接器,女儿(接合)连接器,多个子信号连接器和女儿接合连接器。 警报互连包括相应的母连接器。 互连和接口的相应连接器被布置成当接口被热插拔插入到互连:预充电/接地连接器,警告连接器,信号连接器并且最终接合连接器时,它们以下列示例顺序配合。 当女儿(接合)警告连接器与母体警告连接器配合时,组件向动力系统发送“接合警告”信号。 Eventully,所有的信号连接器都配合接合连接器,使组件能够向系统发送一个“已接合”信号,表明所有的信号连接器已完全配合。 根据本发明的另一方面,该部件还可以首先安全地“热插拔”,从而基本上增加了女孩接合连接器相对于沿着配合边缘的子信号连接器的凹陷度,其次,将 女儿接合连接器作为女儿脱开警告连接器。

    • Snooping is implemented on a split transaction snooping bus for a computer system having one or many such buses. Circuit boards including CPU or other devices and/or distributed memory, data input/output buffers, queues including request tag queues, coherent input queues ("CIQ"), and address controller implementing address bus arbitration plug-into one or more split transaction snooping bus systems. All devices snoop on the address bus to learn whether an identified line is owned or shared, and an appropriate owned/shared signal is issued. Receipt of an ignore signal blocks CIQ loading of a transaction until the transaction is reloaded and ignore is deasserted. Ownership of a requested memory line transfers immediately at time of request. Asserted requests are queued such that state transactions on the address bus occur atomically logically without dependence upon the request. Subsequent requests for the same data are tagged to become the responsibility of the owner-requestor. A subsequent requestor's activities are not halted awaiting grant and completion of an earlier request transaction. Processor-level cache changes state upon receipt of transaction data. A single multiplexed arbitration bus carries address bus and data bus request transactions, which transactions are each two-cycles in length.

    • In the magnetic optical system of a transmission electron microscope (TEM), the increased strength of a second objective lens is used to increase the longitudinal energy dispersion by forming an image at a magnified second back-focal plane. The electric current distribution of other lenses in the microscope is reconfigured to compensate for any offsets introduced by the modified second objective lens. A plurality of deflectors are installed which enable the manipulation of the electron beam electronically between the specimen and the second back-focal plane. The magnified second back-focal plane is projected onto the selected-area aperture, allowing the use of the existing selected-area aperture as an objective aperture to achieve an energy filtering effect which improves the image contrast and resolution.
