    摘要: Systems, methods, and non-transitory computer readable media including instructions for a dual-channel fluid turbine controller. A dual-channel fluid turbine controller includes at least one processor configured to: receive, via an AC channel coupled to an AC output of a fluid turbine, first signals indicating fluctuations in power generated by the fluid turbine operating beneath a grid power supply threshold; access an MPPT protocol; determine a correspondence between the first signals and a portion of the MPPT protocol; apply the portion of the MPPT protocol to a generator of the fluid turbine to generate greater power than would be generated in an absence of the MPPT protocol, wherein the generated power is stored as energy in a capacitor associated with the generator; receive, via a DC channel, second signals indicating a level of energy stored in the capacitor; and use the second signals to determine when to release the stored energy.

    摘要: Systems, methods, and non-transitory computer readable media including instructions for synchronizing a plurality of geographically-associated fluid turbines. Synchronizing a plurality of geographically-associated fluid turbines includes receiving first signals indicative of a phase of a rotational cycle of first rotating blades of a first turbine configured to generate a downstream fluid flow; receiving second signals indicative of a phase of a rotational cycle of second rotating blades of a second turbine configured to receive at least a portion of the downstream fluid flow and generate a differential power output; determining from the first and second signals that greater aggregate power output is achievable through blade phase coordination; determining a phase correction between the first and second rotating blades based on the first and second signals to achieve the greater aggregate power output; calculating coordinating signals based on the phase correction; and outputting the coordinating signals to impose the phase correction.

    摘要: Systems, methods, and non-transitory computer readable media including instructions for coordinating MPPT operations for a cluster of geographically-associated fluid turbines are disclosed. Coordinating MPPT operations for a cluster of geographically-associated fluid turbines includes receiving data from the cluster of geographically-associated fluid turbines; determining changes to total power output of the cluster based on changes in loading states of individual fluid turbines in the cluster; selecting a combination of loading states for the individual fluid turbines in the cluster to coordinate total power output for the cluster; and transmitting the selected combination of loading states to at least some of the individual fluid turbines in the cluster in order to vary rotational speeds of the at least some of the individual fluid turbines in the cluster.

    摘要: A system and method are presented for monitoring user browsing information. Such information can include, but is not limited to, the web pages visited by users, search queries submitted by users, the manner in which users browse the Internet and search for content, as well as any demographic information and interests of the corresponding users. Once a particular type of user browsing information has reached a certain threshold of activity by users, the invention can be configured to detect activity that reaches the threshold and then can increase the monitoring of the information.

    摘要: Described above is a two-pass method of compressing a data input stream to create a compressed data output stream. The method includes a step of sequentially examining data elements and strings of data elements of the data input stream in a first compression pass using a sliding window compression scheme to find literal data elements and pairs of length and displacement values. The first compression pass includes: coding the literal data elements and the length values with a first minimum redundancy coding tree; coding the displacement values with a second minimum redundancy coding tree; and adding the coded literal data elements, length values, and displacement values to a single data buffer. The method also includes a second compression pass that is performed whenever the single data buffer reaches a predefined capacity.

    摘要: A method and system for maintaining a binary tree of pointers to a stream of data and for searching same. A novel binary tree is created by a search engine in which the nodes associated with strings in the data stream which are closer to the current data stream position are nearer the root of the tree than nodes associated with strings which are farther. As the current position in the stream is advanced, the search engine inserts a new node to the tree for that position as the root node. The tree is then restructured based on the relative value of the strings of each node while preserving the temporal order of the tree such that strings nearer the current position are associated with nodes which are closer to the root. The tree is ideal for searching data for LZ77-based data compression, since a single traversal of the tree returns the longest match length with the smallest offset.
