A television receiver including a teletext decoder for receiving and displaying teletext pages for signalling that a requested teletext has been changed or not changed with respect to the previous consultation of the relevant page. To this end the receiver forms a checkword upon reception of a teletext page, which checkword is representative of the contents of the page, and compares this with the checkword stored upon previous display of the page.

A web page can be updated by communicating modification instructions to the web page from a server, through a proxy frame of the web page, such that the modification instructions affect less than the entire web page. This method avoids having to reload the content frame every time a change to content is required thus eliminating screen flash within the browser which generally accompanies navigating between similar pages from the same web site. A source frame can be used to store methods having i...

A method for managing requests for deferred updates to shared data elements while minimizing grace period detection overhead associated with determining whether pre-existing references to the data elements have been removed. Plural update requests that are eligible for grace period detection are buffered without performing grace period detection processing. One or more conditions that could warrant commencement of grace period detection processing are monitored while the update requests are buff...

A method for automatically updating a speed calling data base in a telecommunications network entails tagging an outgoing speed call with a speed calling tag, identifying the telephone number of a speed call as being non-working, retrieving the updated telephone number, and replacing the non-working number in the speed calling data base with the updated number based on update options selected by the calling party. All occurrences of the non-working number could be replaced depending upon options...

A data modem is provided with a boot ROM having a set of instructions for a programmable processor to perform its basic functions within the modem. Enhancements and firmware updates are downloaded over a telephone line through the modem's inherent communications abilities and stored in a battery backed RAM. This permits firmware updates and enhancements to be implemented remotely without need for replacement of ROM or opening of the modem housing.

A continuous weight-update device for a synaptic element including at least one MOS transistor comprises a floating node having a capacitance associated therewith, the floating gate comprising at least a part of the floating node, first and second input lines, first and second error lines, an electron tunneling structure coupled to the floating node for tunneling electrons from the floating node, and an electron injecting structure coupled to the floating node for injecting electrons onto the fl...

A method and apparatus for sample accurate parameter update management in digital audio recording/playback wherein a digital signal processor, memory, recording controller, and appropriate interfacing facilitate storage and retrieval of digital audio data samples continuously to achieve substantially seamless flow and sample accurate audio state updated at precisely designated times, all as required in such critical synchronizing applications as film dubbing.

The present invention provides a new, high-performance system and method for updating databases or other data compilations with changes entered in a source database or data compilation. Updates are preprocessed to reduce system update demands while increasing update flexibility for remote processing sites. Data update records are captured or collected and extracted into one or more channel or other criterion-specific batches. Transaction boundaries within a batch are collapsed, and the records c...

A system and method for dynamically updating software on one or more installation media for installation on at least one destination machine. The invention obtains update content from one or more update media and merges the update content with the software on the installation media prior to installing the software on the destination machine. The software to be installed includes application programs and operating system software.

The present invention provides for a configuration tool that during configuration of a message server assists a user in registering, transferring, maintaining a domain name and/or automatically configuring a message system in accordance therewith. The configuration tool guides the user through a series of inquiries, and based on the user input utilizes a list of registrars for registering a new domain name, configuring the system in accordance with an existing domain name, or transferring an exi...
