    Abstract: A queuing mechanism is presented that allows port data and processor data to share the same crossbar data pathway without interference. An ingress memory subsystem is dividing into a plurality of virtual output queues according to the switch destination address of the data. Port data is assigned to the address of the physical destination port, while processor data is assigned to the address of one of the physical ports serviced by the processor. Different classes of service are maintained in the virtual output queues to distinguish between port data and processor data. This allows flow control to apply separately to these two classes of service, and also allows a traffic shaping algorithm to treat port data differently than processor data.

    Abstract: A routing module applies a plurality of routing rules simultaneously to determine routing for a Fibre Channel frame. Each rule independently determines whether the rule applies to the frame as well as a routing result for the frame. The routing result includes a port address, a zoning indicator, and a priority designation that can be used to route the frame over a virtual channel in an interswitch link. A selector chooses between the results returned by the rules. A component receives routing results specifying an ISL group and selects a physical ISL for the frame. An in-band priority determined by the content of the frame header can also be used in place of the priority designation in the routing result.

    Abstract: A method and apparatus for estimating the orbits of spacecraft or other objects relative to primary celestial bodies, given applicable measurements. The present invention uses the variation of parameters in universal variables for spacecraft trajectory propagation during operation of its optimal sequential orbit estimation. This method provides a universal capability for all three conics: elliptic, parabolic, and hyperbolic, forward-time and backward-time numerical integration for filtering and smoothing, respectively. A method for determining local and global estimates of atmospheric density is also provided. A method for realistic orbit simulation provides a means for validating an orbit estimate.

    Abstract: An interface that allows a surgeon to remotely control surgical devices and conditions of an operation room. The surgeon views a video image that is displayed by a monitor. The monitor may be coupled to a video device such as a laparoscopic camera that is attached to the end of an endoscope. Static graphic images and a dynamic graphic cursor are overlayed onto the video image. The graphic cursor has a pixel location on the monitor which corresponds to a spatial location of a pointer signal. The pointer signal is transmitted by a transmitter worn on the head of the surgeon. The pointer signal may be a laser which is directed to a screen that is located adjacent to a detection camera. The surgeon may move the graphic cursor relative to the video image by tilting his head and varying the spatial location of the pointer signal. The interface may have a controller which generates output signals in response to the movement of the pointer signal. The output signals may move a robotic arm which controls the position of the endoscope. The controller may also generate command signals when the graphic cursor is moved into a static graphic image. The command may vary a condition of the operating room such as the position of the operating table.
