Publication number: 20240004964Abstract: Many areas of investigation require searching through data that may be of interest. In a first method step, a digital content element is provided. The digital content element may have any suitable format or data structure of interest to a searching entity. The digital content element may be a particular data file that is of interest to a searching entity. In a second step, the digital content element is compared with a first set of data provided by a combination of a second set of data and a third set of data. The first set of data is a collection of known digital content elements that are of interest to a searching entity, for example contraband digital content elements or digital content elements owned by or represented by the searching entity. In a third method step, the digital content element is identified as known if the digital content element is detected within the first set of data.Type: ApplicationFiled: September 18, 2023Publication date: January 4, 2024Inventors: William Johnston Buchanan, Owen Chin Wai Lo, Philip Penrose, Richard Macfarlane, Ian Stevenson, Bruce Ramsay

Patent number: 11601403Abstract: A management request is received by a system for carrying out one or more data management operations (including, but not limited to, adding data, merging data or searching for data). The management request is received from a requesting entity. The system comprises a representation database, which comprises at least one secure element. The at least one secure element is a representation of at least one dataset containing confidential data elements stored in at least one database owned or operated by a third party entity. The management request is processed by performing at least one operation, for example by a processing component in the system, on the representation database. In a third step, a processing result is provided, which comprises any suitable information or data content. The processing result is dependent on the contents of the management request.Type: GrantFiled: March 12, 2018Date of Patent: March 7, 2023Assignee: CYACOMB LIMITEDInventors: William Johnston Buchanan, Owen Chin Wai Lo, Philip Penrose, Richard Macfarlane, Ian Stevenson, Bruce Ramsay

Publication number: 20150337643Abstract: A downhole logging tool and method of use for analysing portions of a seafloor borehole in seafloor drilling operations are provided. The downhole logging tool h an underwater chassis housing a power system and sensors including at least a conductivity sensor and a magnetic susceptibility sensor which, preferably, analyse the walls of the borehole. An automatically actuated switch, preferably actuated magnetically, provides power to the sensors from the power system when the downhole logging tool is not located in a designated portion of a seafloor drilling rig (e.g. when the tool is in use traversing a borehole) and removes power when the downhole logging tool is located in the designated portion of the seafloor drilling rig (e.g. when the downhole tool is not in use).Type: ApplicationFiled: June 12, 2013Publication date: November 26, 2015Applicant: NAUTILUS MINERALS PACIFIC PTY LTDInventors: Stuart Leach, Ian Stevenson, Sean Plunkett, Melanie Devaux, Peter Hampton, Eric Jackson

Patent number: 8967783Abstract: What is disclosed is a system and method for printing a cancellation mark on a ticket using inks having thermo-reactive properties. One embodiment of the present method for printing a cancellation mark onto a ticket involves the following. A ticket, which has a security mark printed thereon, is received into a slot of a housing of a device which contains therein an inkjet printhead. The received ticket portion comes into proximity with an inkjet printhead configured to print a cancellation mark on the ticket using the thermo-reactive ink. The cancellation mark is printed to at least partially overlap the security mark. In one embodiment, a user activates a switch which causes the inkjet printhead to print the cancellation mark on the ticket upon the ticket having been inserted into the slot. Various embodiments are disclosed.Type: GrantFiled: December 17, 2012Date of Patent: March 3, 2015Assignee: Xerox CorporationInventors: Michael John Wilsher, Christopher D.

Patent number: 8960843Abstract: What is disclosed is a multi-function inkjet print system which prints with inks having thermo-reactive properties and which can further process media printed with thermo-reactive inks such that the various properties of the inks can be activated. One embodiment of the present print device comprises at least one thermo-changing element which resides in proximity to a transport path along which the media travels. The thermo-changing element effectively changing a temperature T of the media to: T?TL or T?TH, as desired. In various embodiments, a sensor is used for sensing a temperature of the media. A temp-normalizing element is positioned along the transport path and downstream of the thermo-changing element for changing a temperature of the media such that the media's temperature T can be normalized back to a range of TL<<T<<TH prior to the media being deposited into an output tray. Various embodiments of a user interface are disclosed.Type: GrantFiled: December 17, 2012Date of Patent: February 24, 2015Assignee: Xerox CorporationInventors: Michael John Wilsher, Christopher D.

Patent number: 8864254Abstract: What is disclosed is a multi-function system which receives media printed with ink having thermo-reactive properties and which processes the received media such that the ink becomes visually transparent. One embodiment of the present system comprises an input tray for receiving printed media into a transport path along which the media travels. A heating element resides in proximity to that transport path for changing a temperature T of the media to T?TH. In various embodiments, a temp-normalizing element is positioned along the transport path downstream of the heating element for changing a temperature of the media such that the media's temperature T can be normalized back to a temperature range TL<<T<<TH prior to the media being deposited into an output tray such that the processed media is no longer hot to the touch. A user interface enables a user to perform various functions. Embodiments of a user interface are disclosed.Type: GrantFiled: December 17, 2012Date of Patent: October 21, 2014Assignee: Xerox CorporationInventors: Michael John Wilsher, Christopher D.
