    摘要: A system constructs an OSPF-compatible virtual model of a multi-hop, multi-access packet radio network that includes a plurality of routers (120) and which includes its own private, internal routing system (150), in order to facilitate the incorporation of that packet radio network into an overall OSPF routing environment. The system determines a network graph identifying actual connectivity among the plurality of routers (120). The system constructs a virtual model (300) of the, wherein connectivity of the virtual model may be different than the actual connectivity of the network graph. The system represents the multi-hop, multi-access radio network in the virtual model as a set of multi-access links (305, 310), point-to-point links, AS-external routes, and area summary routes. The system employs the virtual model for routing purposes and advertises the virtual model to other OSPF routers for the same purpose.

    摘要: A target test framework and method are provided which can enable scenario writer(s) to design and implement driver test(s) by providing a platform to build scenario-based automated tests for device(s) and device driver(s) by using a set of components designed for target testing. The framework enables scenario writer(s) to perform a set of actions across different types device(s). The framework further enables the testing of technology areas common to many targets (e.g., plug and play, power management, install/uninstall, security etc.). Additionally, the framework facilitates automatic identification and/or running of prewritten core functionality test that apply to a particular device. The framework further can allow runtime control of tests and the combining of framework components to form new device functionality tests and large scale scenarios.

    摘要: A device for measuring anode tube current or filament current in an X-ray tube, comprising a coil of wire wrapped around an insulating tube to generate a solenoidal magnetic field, one or more pieces of magnetic material and insulating material located within the tube (which magnetic elements may have their electrical potential stabilized by a resistive voltage divider), and a Hall Effect current sensor (HECS) located at the far end of the tube and insulated from the magnetic material. The output of the Hall Effects sensor is connected to an amplifier circuit, and a secondary coil of wire is used to capture the high frequency component of the magnetic signal. The secondary coil is connected to a current amplifier circuit which is followed by a high pass filter to only provide components above the cross over frequency of the hall sensor. The two signals are combined with an amplifier to provide a broad band signal that may be viewed by a current amplifier.

    摘要: A device access controller residing in a first computer system for transferring virtual inputs and outputs representing operations of the first system between the first system and a second system. The device access controller includes a video controller for performing video display operations, a video memory for storing video data representing operations of the first system, a network controller for transferring information between the first system and the second system, a controller processor, and a device access controller bus interconnecting the video controller, the network controller and the processor. A video interface is connected between the first system bus and the device access controller bus for receiving video information including video data and video write addresses from the first system bus and into the video memory and controller and the controller processor and network controller are responsive to the writing of video data into the video memory for reading the video information including the video data from the video memory and the video data write addresses from the video controller registers and transmitting the video information including the video data and the video data write addresses to the second system. The device access controller further includes a keyboard interface, a disk interface, and a serial interface operating in manners generally analogous to the video interface for corresponding communicating corresponding data between the first and second systems.
