International Classification:

G06F 13/00

US Classification:

711159, 711154, 711166

Abstract:

The present invention is directed to a system and method for the secure and correct deletion of data files from a data storage that bypasses the file system of an operating system. A secure erase service receives a secure erase request from a system interceptor component, which has intercepted a system call from an application. The system call interceptor component communicates with the secure erase service via an interprocess communication module. The secure erase service receives the secure erase request from the interprocess communication module and communicates the secure erase request to a secure erase library. Using the file information contained in the secure erase request, the secure erase library queries the file system of the data storage device to determine the location of data blocks containing the to be deleted data. Once, the location of the data blocks has been determined, the secure erase library then instructs the device driver, via a virtual file system, to overwrite the data blocks storing the electronic file a predetermined number of times.

Abstract:

The present invention enables users to interface with a wide range of computing and telecommunication devices seamlessly without a cable connecting the devices. As such, the present invention allows for the replacement of the many proprietary cables that connect one device to another with one universal short-range radio link. The typical BLUETOOTH system consist of four basic components: a radio (RF section) that receives and transmits data and voice; a baseband or link control unit that processes the transmitted or received data; link management software that manages the transmission; and supporting application software. Electronic devices incorporating BLUETOOTH technology will replace RS-232, parallel, Universal Serial Bus (USB), and other types of cables with a single, standard wireless connection. BLUETOOTH radio technology will also provide a universal bridge to existing data networks, a peripheral interface, and a mechanism to form small private ad hoc groupings of connected devices away from fixed network infrastructures.

International Classification:

G06F 21/00
H04L 29/06

US Classification:

726 4, 726 21, 713185

Abstract:

A system and method for the selective sharing of an electronic document. The method enables a user to share access to an electronic document stored on a repository on a document management system. A user, via a document processing services network, generates a password and token corresponding to the document to be shared. The token provides information regarding the electronic document to be shared and the way the shared document will be made available to other users. The user then gives the token along with the password to the other users desiring to have access to the shared document. The other users are then able to retrieve the electronic document via email, viewing on a web browser, or printing at a multifunction peripheral device.

US Classification:

358 115, 709201

Abstract:

A system and method for selective rerouting of document processing jobs is provided. A printer driver first converts electronic document data is into a device compatible format and assigned a unique document ID. The printer driver then determines a set of network devices, such as document processing devices, that are participating in the performance of received document processing jobs. The converted document data is then divided into portions and one or more portions are then sent to each of the participating network devices. One of the devices is then selected as the output device, whereupon the output device broadcasts/multicasts a request for processed data portions from each of the other network devices. The received portions are then recombined, and released for further processing in accordance with the received document processing job.

US Classification:

600 37

Abstract:

A gastrointestinal implant system includes an adjustable restriction device having a contact surface configured for at least partially engaging a surface of a gastrointestinal tract of a mammal. The implant system further includes an implantable interface including a first driving element, the first driving element being moveable and operatively coupled to the adjustable restriction device by an actuator configured to change the dimension or configuration of the contact surface in response to movement of the first driving element. The system also includes an external adjustment device having a second driving element configured to non-invasively engage the first driving element of the implantable interface from a location external to the mammal. In the system, actuation of the second driving element of the external adjustment device produces movement in the first driving element of the implantable interface and results in a change in the dimension or configuration of the contact surface.

US Classification:

358 115, 358 114

Abstract:

A system and method for controlled monitoring of pending document processing operations is provided. Each document processing request received by a document processing device is assigned a job name, which is then encrypted using a random static encryption key, resulting in a job identification. A user then logs onto the document processing device to view pending jobs, which are displayed to the user by only job identification. Those jobs with which the user is associated are then decrypted by the document processing device, allowing the user to view job information including status and file name. The user is thereby also able to modify or delete those pending jobs with which the user is associated. Once the job queue is empty, the random static encryption key is deleted and a new key is generated when a document processing request is received into the empty queue.

International Classification:

US Classification:

358 115

Abstract:

The subject application is directed to a mobile document processing system and method. A request for a transient address corresponding to mobile document processing operations is first received from an associated user. Upon receipt of the request, a transient address is generated corresponding to the associated user. Transient address data is then generated for routing electronic documents in accordance with a received document processing request. A document processing request is then received corresponding to a request for the performance of processing of at least one electronic document. The at least one electronic document is then routed to an associated document processing device, data storage device, or facsimile device corresponding to the transient address. The associated document processing device, data storage device, or facsimile device then commences a document processing operation according to the received document processing request. Upon the occurrence of a selected event, the transient address is deleted.
