    Abstract: A load balancing system is described herein that proactively balances client requests among multiple destination servers using information about anticipated loads or events on each destination server to inform the load balancing decision. The system detects one or more upcoming events that will affect the performance and/or capacity for handling requests of a destination server. Upon detecting the event, the system informs the load balancer to drain connections around the time of the event. Next, the event occurs on the destination server, and the system detects when the event is complete. In response, the system informs the load balancer to restore connections to the destination server. In this way, the system is able to redirect clients to other available destination servers before the tasks occur. Thus, the load balancing system provides more efficient routing of client requests and improves responsiveness.

    Abstract: An intelligent caching system is described herein that intelligently consolidates the name-value pairs in content requests containing query strings so that only substantially non-redundant responses are cached, thereby saving cache proxy resources. The intelligent caching system determines which name-value pairs in the query string can affect the redundancy of the content response and which name-value pairs can be ignored. The intelligent caching system organically builds the list of relevant name-value pairs by relying on a custom response header or other indication from the content server. Thus, the intelligent caching system results in fewer requests to the content server as well as fewer objects in the cache.

    Abstract: A caching system segments content into multiple, individually cacheable chunks cached by a cache server that caches partial content and serves byte range requests with low latency and fewer duplicate requests to an origin server. The system receives a request from a client for a byte range of a content resource. The system determines the chunks overlapped by the specified byte range and sends a byte range request to the origin server for the overlapped chunks not already stored in a cache. The system stores the bytes of received responses as chunks in the cache and responds to the received request using the chunks stored in the cache. The system serves subsequent requests that overlap with previously requested ranges of bytes from the already retrieved chunks in the cache and makes requests to the origin server only for those chunks that a client has not previously requested.

    Abstract: A magnetic repulsion-actuated magnetic bearing is constructed to include a stator, two magnetic repulsion modules mounted inside the stator, a rotor having two annular permanent magnets at the ends corresponding to the two magnetic repulsion modules. A magnetic force of repulsion is produced between equiangularly spaced permanent magnets of the magnetic repulsion modules and the annular permanent magnets of the rotor to keep the rotor radially in position automatically upon power failure. A controller is electrically connected to windings of the magnetic repulsion modules for controlling the current of the windings to change the intensity of magnetic force so as to further control the radial magnetic force of repulsion of the magnetic repulsion actuators, keeping the radial bearing stiffness during rotation of the rotor.
