When a remote server transmits encoded video frames to the client, the client decodes those video frames and applies the summed motion vectors to the decoded frames to estimate motion in those frames. In certain embodiments, the systems and methods generate motion vectors at a server based on predetermined criteria and transmit the generated motion vectors and one or more invalidators to a client, which caches those motion vectors and invalidators. The server instructs the client to receive input from a user, and use that input to match to cached motion vectors or invalidators. Based on that comparison, the client then applies the matched motion vectors or invalidators to effect motion compensation in a graphic interface. In other embodiments, the systems and methods cache repetitive motion vectors at a server, which transmits a previously generated motion vector library to a client. The client stores the motion vector library, and monitors for user input data. The server instructs the client to calculate a motion estimate from the input data and instructs the client to update the stored motion vector library based on the input data, so that the client applies the stored motion vector library to initiate motion in a graphic interface prior to receiving actual motion vector data from the server. In this manner, latency in video data streams is reduced. |

System and method for throttling service requests having non-uniform workloads
A system that provides services to clients may receive and service requests, various ones of which may require different amounts of work. The system may determine whether it is operating in an overloaded or underloaded state based on a current work throughput rate, a target work throughput rate, a maximum request rate, or an actual request rate, and may dynamically adjust the maximum request rate in response. For example, if the maximum request rate is being exceeded, the maximum request rate may be raised or lowered, dependent on the current work throughput rate. If the target or committed work throughput rate is being exceeded, but the maximum request rate is not being exceeded, a lower maximum request rate may be proposed. Adjustments to the maximum request rate may be made using multiple incremental adjustments. Service request tokens may be added to a leaky token bucket at the maximum request rate. |

Laser apparatus and method of processing thin films
A method of fiber laser processing of thin film deposited on a substrate includes providing a laser beam from at least one fiber laser which is guided through a beam-shaping unit onto the thin film. The beam-shaping optics is configured to shape the laser beam into a line beam which irradiates a first irradiated thin film area Ab on a surface of the thin film, with the irradiated thin film area Ab being a fraction of the thin film area Af. By continuously displacing the beam shaping optics and the film relative to one another in a first direction at a distance dy between sequential irradiations, a sequence of uniform irradiated thin film areas Ab are formed on the film surface defining thus a first elongated column. Thereafter the beam shaped optics and film are displaced relative to one another at a distance dx in a second direction transverse to the first direction with the distance dx being smaller than a length of the irradiated film area Ab. With the steps performed to form respective columns, the elongated columns overlap one another covering the desired thin film area Af. The dx and dy distances are so selected that that each location of the film area Af is exposed to the shaped laser beam during a cumulative predetermined duration. |
