Patent number: 9602569Abstract: Telecommunications equipment may require network connectivity. On newer systems, an additional local management interface is provided for proprietary maintenance functions, typically via a shell-based Command Line Interface. This is not available on remote sites with only TDM connections. The invention provides a method of communicating between a management console and remote access equipment via a class 4 telecommunications switch, which comprises establishing an IP connection, establishing a synchronous telecommunications transport connection between the class 5 switch and the remote access equipment, setting up a voice call between the management console and the remote access equipment, passing the voice call over the IP connection as a VOIP call, passing the voice call over the synchronous telecommunications transport connection as a PCM encoded call, and encapsulating an IP data stream in the VOIP and PCM encoded call to establish an end-to-end IP.Type: GrantFiled: February 14, 2013Date of Patent: March 21, 2017Assignee: Metaswitch Networks LimitedInventors: Craig Miller, John Batty, John Tucker, Mark Overton, Shriman Gurung, Doug Theobald, David Smith

Publication number: 20140226653Abstract: Existing telecommunications equipment may require network connectivity for data transfer but may have no external interfaces except for the TDM voice circuits to which they are connected. Thus on most newer systems, an additional local management interface is provided for proprietary maintenance functions. This is typically accessed via a shell-based Command Line Interface. This cannot be used on a remote site with only TDM connections.Type: ApplicationFiled: February 14, 2013Publication date: August 14, 2014Applicant: METASWITCH NETWORKS LIMITEDInventors: CRAIG MILLER, JOHN BATTY, JOHN TUCKER, MARK OVERTON, SHRIMAN GURUNG, DOUG THEOBALD, DAVID SMITH

Patent number: 8527468Abstract: Disclosed are embodiments of a system and method for establishing and managing document retention policy in a distributed computing environment. One embodiment comprises the steps of loading documents into a database as individual components or items; establishing a custodian for each document instance; categorizing its content into a plurality of categories; assigning retention periods to the content by category; and continuously monitoring retention policies according to the assigned retention periods. Any database capable of storing de-duplicated data can be adapted to implement embodiments of the invention. One embodiment utilizes codified algorithms to cross-match one or more retention policies with each document instance in the system based on the role of the custodian held at the time the instance was created and retained and/or the content or category of the content to which the document refers. If multiple policies apply, the retention period is set to the furthest in the future.Type: GrantFiled: February 8, 2006Date of Patent: September 3, 2013Assignee: Renew Data Corp.Inventors: Chris Crafford, Robert Gomes, Alan Royce Brooks, Jeffrey Mark Overton

Patent number: 5838838Abstract: In a preferred method for horizontal down-scaling of a pixel pattern, the down-scaling is performed on a byte-by-byte basis along each row of pixels. To avoid loss of information, if a pixel to be deleted is black and the black pixel has two original white immediate neighbors, the pixel to the right of the black pixel to be deleted is set to black. Each byte may be processed independently from the other bytes. In a preferred method for vertical down-scaling of a pixel pattern, a pixel row to be deleted, to achieve the desired down-scaling, is identified. To avoid loss of information, pixels in a byte of pixels in the row to be deleted are bit-wise logically OR'd with the corresponding pixels in the next row, and the OR'd values replace the pixels in that next row. Changing the pixel values during the horizontal or vertical down-scaling is only performed if it is determined that the byte is part of text and not part of a picture.Type: GrantFiled: July 19, 1996Date of Patent: November 17, 1998Assignee: Hewlett-Packard CompanyInventor: Mark A.

Patent number: 5801843Abstract: An improved method for providing a more faithful and pleasing rendition of a pixel pattern is described herein. This method first places the original pixel pattern in a bit mapped memory. A small portion of this bit mapped pattern, called an input tile, acts as an address for a look-up table containing a corrected pixel pattern portion (an output tile) corresponding to the target pixels to be corrected in the input tile. To derive the output tiles stored in the look-up table, a high resolution bit map is created from an input tile by scaling the input tile. A triangular portion of each convex corner in the high resolution bit map is chopped off, and a triangular portion of each concave corner in the high resolution bit map is filled in. The resulting pattern is then smoothed using a low pass filter. The size of these triangular portions and the extent of low pass filtering are determined using a function based on the vulnerability of a pixel to being eliminated during the above smoothing process.Type: GrantFiled: June 4, 1996Date of Patent: September 1, 1998Assignee: Hewlett-Packard CompanyInventor: Mark A.

Patent number: 5574832Abstract: Techniques are disclosed for depleting raster data to allow printing of the depleted raster data on a grid that corresponds to the resolution of the undepleted raster data with a printed dot size that is larger that would otherwise be utilized with the undepleted raster data and to achieve faster ink dry time. Also disclosed is a technique for up scaling raster data at a particular resolution (e.g., 300 dpi) to a higher resolution in such a manner that expanded data includes a greater number of dot producing pixels to compensate for a dot size that is larger than the dot size that is appropriate for the higher resolution, and does not require horizontal depletion for printing with such dot size. This allows raster data at a particular resolution to be combined with higher resolution rasterized vector data for printing in accordance with the enhanced mode of operation.Type: GrantFiled: April 30, 1993Date of Patent: November 12, 1996Assignee: Hewlett-Packard CorporationInventors: David C. Towery, Alan E. Cariffe, Janet E. Mebane, Anne P. Kadonaga, Iue-Shuenn Chen, Mark Overton
