A method and system which allows a remote monitoring and diagnostic computer or system to communicate using different communication protocols which are stored within a data base. After a communication is received, it is analyzed to determine if there is a protocol identifier. If the protocol identifier exists, a data base is searched to determine the format of the header of the communication. Once the format of the header is determined, the header of the received communication is read to determi...

A method, and apparatus in an ISDN system form a setup message at a source ISDN terminal where the setup message includes a resource coordination message containing the communication attributes of the source terminal. The ISDN source terminal sends the setup message to an ISDN switch, where the ISDN switch implements a central resource coordination mechanism that extracts the source terminal attribute information. The ISDN switch sends an inquiry message over a D channel to a destination termina...

A multi-function machine for combining and routing image data is disclosed. The multi-function machine includes a number of functional units, for instance, a digital copier which produces scanned image data, a printer which prints image data from a computer, and a facsimile device which receives and sends facsimile image data. Image data from one or a number of sources may be combined to form merged image data, corresponding to a merger of the individual images. The merged image data may then be...

A method and system for forming a digital facsimile message that includes a subaddress. A source terminal forms a digital facsimile message by using information input by a user in response to prompting inquiries generated by the source terminal. In response to a prompt, a user enters whether the user will enter a subaddress to route the message to a destination terminal. If an affirmative response is received, the source terminal prompts the user to input the subaddress and later to input a tele...

A compression and decompression system in which a reversible wavelet filter are used to generates coefficients from input data, such as image data. The reversible wavelet filter is an efficient transform implemented with integer arithmetic that has exact reconstruction. The present invention uses the reversible wavelet filter in a lossless system (or lossy system) in which an embedded codestream is generated from the coefficients produced by the filter. An entropy coder performs entropy coding o...

A system and method for performing scanning operations using a scanner connected to a server computer and transmitting acquired images from the scanner server to a client computer. A scan-to-application process is utilized which allows control of the scanner or other image acquiring device which is connected to a scanner server using a virtual TWAIN driver which interfaces to an application program running in the client computer. Image files are also transmitted to a local file storage device of...

In an electrophotographic copying apparatus, the document stack to be fed is curved when it rests on a fixed curved stack-holding tray. The document stack is lifted by a pair of lifting blades having the curvature of the stack which move horizontally relative to the ends of the stack to move in and out beneath the sides of the stack, and thereafter move vertically to lift the entire stack out of the path of the returning copy. A vacuum belt arrangement is provided for moving successive documents...

An apparatus for communicating with a plurality of remote machines, of a plurality of machine types includes a computer system including a processor and memory a data communication means, coupled to the computer system and to the plurality of remote machines, for communicating with each of the plurality of remote machines, a first plurality of software objects within the memory for describing services for the plurality of remote machines, and a plurality of operations within the memory associate...

A reversible Discrete Cosine Transform (DCT) is described. The reversible DCT may be part of a compressor in a system. The system may include a decompressor with a reversible inverse DCT for lossless decompression or a legacy decompressor with an inverse DCT for lossy decompression.

A method and apparatus that provides any type of data information in a facsimile message is configured to accept data information at a source terminal from an external device and send the data information to one or more destination terminals via a facsimile message. In particular, a processor formats the data information in the form of one or more non-standard frames that are conventionally used only to support point to point polling operations for two facsimile devices. The data information is ...
