A communication system providing telephony communication across combined circuit switched and packet switched networks, such as a telephone network and the Internet, which are connectable to terminals, such as telephones and computers, for selective communication therebetween. The communication system includes an authorization and account control object in the packet switched network, multiple gateways between the circuit switched and packet switched networks providing controlled connectivity between those networks, and an information retrieval object in the packet switched network, wherein the authorization and account control object maintains a substantially real time record of user accounts and usage, and the information and retrieval object provides substantially real time retrieval of selected information from the authorization and account control object. The retrieval object provides on demand to terminals which provide authentication for access to an identified account information regarding that account. The information regarding the account is substantially real time information including information with respect to communications in progress which are chargeable to the account which has been authenticated. The authorization and account control object is preferably a unitary logical object having distributed instances thereof handling multitudinous accounts of widely separated terminals.

The system described herein facilitates the control, by spoken input, of multiple user application programs running under an operating system providing multi-tasking capability. A speech recognition program runs as one of the multi-tasked programs. The recognition program is operative to provide translation, either text or program commands, of spoken words in accordance with a translation table. Each of the other user application programs which is to be controlled is provided with a respective translation table section. In accordance with the invention, the recognition program includes means for creating a database for each of the other user application programs which is run and stores, in the respective database, a record reflecting each translation which is sent to a running one of the other application programs. These records identify the speech event which was translated and also identifies alternate possible translations of the speech event. Using the databases, the user can undo the effect of a previously sent translation, select an alternate translation and perform other editing tasks.

This invention also relates to construction of object-oriented, parallel computer languages, script and visual, together with compiler construction and method to write programs to be executed in fully parallel (or multi-processor) architectures, virtually parallel, and single-processor multitasking computer systems.

The present invention relates to a system that facilitates multi-tasking in a computing environment. A focus area component defines a focus area within a display space—the focus area occupying a subset area of the display space area. A scaling component scales display objects as a function of proximity to the focus area, and a behavior modification component modifies respective behavior of the display objects as a function their location of the display space. Thus, and more particularly the subject invention provides for interaction technique(s) and user interface(s) in connection with managing display objects on a display surface. One aspect of the invention defines a central focus area where the display objects are displayed and behave as usual, and a periphery outside the focus area where the display objects are reduced in size based on their location, getting smaller as they near an edge of the display surface so that many more objects can remain visible. In addition or alternatively, the objects can fade as they move toward an edge, fading increasing as a function of distance from the focus area and / or use of the object and / or priority of the object. Objects in the periphery can also be modified to have different interaction behavior (e.g., lower refresh rate, fading, reconfigured to display sub-objects based on relevance and / or visibility, static, etc.) as they may be too small for standard rendering. The methods can provide a flexible, scalable surface when coupled with automated policies for moving objects into the periphery, in response to the introduction of new objects or the resizing of pre-existing objects by a user or autonomous process.

Using marks of known dimensions and size, and spacing, a zoom lens may be calibrated in either or both the X and Y spatial directions. A system comprising an image capture device, positioning means, position encoder means, operator interface, and processing unit permits this method to be advantageously applied to a wide variety of web inspection / control functions, including but not limited to initial web registration, multiple color ink registration, lateral web positioning, repeat length calculations, image capture synchronization, thermal / mechanical differential compensation, and accurate registration of objects within an image to other objects within an image or to a mechanical reference on a machine. Since the Zoom Calibration method permits a system to be constructed with both wide / variable field of view and accurate distance measurement positioning and calibration, all of the web inspection / control functions traditionally used in the web printing industry may be implemented with a single inspection / control system using a multitasking approach with the same inspection / control hardware. This permits rapid implementation of old and new web inspection / control functions at a greatly reduced cost as compared to traditional fixed lens systems, as well as permitting a degree of automation, remote access, diagnostic control, quality assurance, and product quality control heretofore not possible with conventional web inspection / control systems.
