A new Fault Detection and Exclusion (FDE) approach for tightly integrated GPS/inertial sensors that combines a normalized solution separation for fault detection and a residual monitoring scheme for fault exclusion is described. The computation of the detection threshold, the horizontal protection level and the horizontal uncertainty level are also presented. This new FDE algorithm is designed to enable the tightly integrated GPS/inertial sensor to be used as a primary means of navigation sensor for civil aviation.

A computer system having a fault-tolerance framework in an extendable computer architecture. The computer system is formed of clusters of nodes where each node includes computer hardware and operating system software for executing jobs that implement the services provided by the computer system. Jobs are distributed across the nodes under control of a hierarchical resource management unit. The resource management unit includes hierarchical monitors that monitor and control the allocation of resources. In the resource management unit, a first monitor, at a first level, monitors and allocates elements below the first level. A second monitor, at a second level, monitors and allocates elements at the first level. The framework is extendable from the hierarchy of the first and second levels to higher levels where monitors at higher levels each monitor lower level elements in a hierarchical tree. If a failure occurs down the hierarchy, a higher level monitor restarts an element at a lower level. If a failure occurs up the hierarchy, a lower level monitor restarts an element at a higher level. Each of the monitors includes termination code that causes an element to terminate if duplicate elements have been restarted for the same job. The termination code in one embodiment includes suicide code whereby an element will self-destruct when the element detects that it is an unnecessary duplicate element.

A distributed, digital, network-based, streaming video solution allows users to view live streaming digital video from multiple video sources in multiple operating rooms at any location connected to a network. One or more video sources in an operating room are connected to a streaming video encoder capable of converting the video to a network packet stream. Once the digital video stream is available on the network, it may be accessed and routed through the use of a streaming video control server. The streaming video control server is responsible for user authentication and authorization and web page access for remote viewing and video source selection by users. The control server also provides audit logging services, operating room selection and overall system resource allocation. The video control server also provides a network-based remote control interface, which enables other systems to communicate on the streaming video network, and allows for remote control of visualization from an integrated operating room control system, and provides the ability for one operating room to look into other operating rooms.

The invention is intended for sizing separation of difficult-to-screen powder materials and slurries. A sieve assembly includes a rigid frame, attached inside the separator housing, and upper and bottom sieves, stretched on the frame. The interface apparatuses are connected to the upper sieve, while actuator means—to the bottom sieve. The forced frequency of the vibrator is close to one of the natural frequencies of the bottom sieve. When the vibrator is operated, the actuator means interact with interface apparatuses, thus generating repeated collisions therebetween and mechanical impulses, which provide multifrequency excitation of the interface apparatuses and upper sieve. This ensures continuous self-cleaning of the upper sieve, intense loosening of the material bed and disintegration of the particle agglomerates. Separation capacity and products' quality substantially rises. In other embodiments presented sieve assembly includes buffer elements and inertial apparatuses, connected to the upper sieve.
