Patent CA-2497693-C (CA)
Inventor: BUI QUY DUC
IPC: B05B1/30
Filed: 2003-09-15
Granted: 2011-11-01
Abstract: A flexible, self-adjusting flow nozzle is provided, optimally configured for agricultural uses. The nozzle flexes automatically in response to changes in fluid pressure, thereby maintaining an optimal droplet size and spray area for a variety of flow rates. The self-adjusting characteristic of the nozzle allows for the creation of a fully or semi-automatic spray system. The fully automatic system uses a GPS receiver to compare actual geographic data against a predetermined flow plan for automatically making adjustments to flow rate in order to accommodate both speed changes and varying crop needs. The semi-automatic system uses a manually controlled flow rate but utilizes the self-adjusting capabilities of the spray nozzle.

Granted: 2013-07-02
Abstract: A method and system are related to updating objects over limited bandwidth networks. Objects are updated between two or more computing devices using remote differential compression (RDC) techniques such that required data transfers are minimized. In one aspect, efficient large object transfers are achieved by recursively applying the RDC algorithm to its own metadata; a single or multiple recursion step(s) may be used in this case to reduce the amount of metadata sent over the network by the RDC algorithm. Objects and/or signature and chunk length lists can be chunked by locating boundaries at dynamically determined locations. A mathematical function evaluates hash values associated within a horizon window relative to potential chunk boundary. The described method and system is useful in a variety of networked applications, such as peer-to-peer replicators, email clients and servers, client-side caching systems, general-purpose copy utilities, database replicators, portals, software update services, file/data synchronization, and others.
