A system for deploying applications over a distributed network to web-enabled devices uses a server, with stored text files containing application logic, and an application assembler. The application assembler downloads and installs on each web-enabled device. Then, the application assembler downloads one or more text files from the server, retrieves program logic from each of the downloaded text files, and assembles the retrieved program logic into a functioning application. In some instances, a plugin that is downloaded and installed on each web-enabled device is activated by web pages on the server to launch the application assembler.

A method and system are configured for synchronous broadcast communications by applying signature keys using hashing functions. Each subsequent transmission in a sequence includes a signature key that can be verified by hashing to a preceding signature key from a previous portion of the sequence. The first transmission in the sequence is signed using a signature key that is known by the client device, typically verified using some other mechanism such as asymmetric key signatures. Each client device can utilize an internal counter for the current time or the block number in the transmission sequence to maintain synchronized transmissions in the even that a particular portion of the sequence is missed, and to validate signature keys. Since the signature keys can be validated when they are received but not predicted before they are received, the transmission is difficult to attack while synchronization is maintained.

A computer system for the indexing of data in which a heuristic determination function is applied to predict an efficient index updating approach. The system is able to update an index relating to a first data set by incrementally updating the index or by a rebuild of the index at the completion of the addition of a second set of data to the first set of data. The system applies a heuristic determination function to the characteristics of the first set of data, its index, and the second set of data, to predict whether an incremental update or a rebuild update of the index will result in a more efficient rebuild of the data. The system applies this approach to a restore and rollforward recovery or a data load operation to improve the efficiency of these operations.

Every printing system has characteristic defects which detract from high quality printing. Xerographic printing systems show defects such as banding, mottled colors in large fill areas, trail-edge deletion and starvation where toner concentrations drop at certain color edges, misregistration, and so on. Ink jet printing systems can show ink bleeding, streaking in the direction of head movement, and so on. One approach to reducing printer defects is to refine the electro-mechanics for more precise printing. Another approach which works for predictable defects is to modify the digital data being sent to the printer to pre-compensate for the defect. The prior art does this to a limited extent for individual object types (strokes, fills, images, text, etc.) and for misregistered color edges (trapping). This invention extends the range of edge-related defects that can be both predicted and pre-compensated for. An embodiment of the invention is described which pre-compensates for defects such as trail-edge deletion, starvation, misregistration, halo, etc. by identifying runs of color which meet the criteria likely to cause the effect and applying a function f(edge-distance, object-type) to such runs to modify them appropriately. Both the prediction criteria and the functions applied are anamorphic (the scan direction and process direction are treated differently) and object-optimized (object attributes are taken into account). Further, both prediction criteria and applied correction functions allow user-settable input.
