Patent number: 9854148Abstract: In a system for detecting location of an object inside of a building, an image capture device of a mobile electronic device captures an image of a boundary of a room in which the portable electronic device is positioned. The system extracts features of a boundary (ceiling, wall or floor) in the image to determine whether the mobile device is in a known location. When the system identifies a known location, it will take an action that provides the portable electronic device with additional functionality at the identified known location. Such functionality may include connecting to a wireless network or communicating with a stationary device at the known location.Type: GrantFiled: August 4, 2015Date of Patent: December 26, 2017Assignee: Xerox CorporationInventors: Gavan Leonard Tredoux, Premkumar Rajendran, Peter J.

Patent number: 9454715Abstract: Methods and systems for transparently extending a multi-function device onto a mobile communications device. The mobile communications device and the multi-function device can be securely connected utilizing a random code displayed on a user interface of the MFD. An extensibility application associated with the MFD can be transparently combined with an execution environment of the mobile communications device to offer a number of services. A hardware and software resource of the MFD and the mobile communications device can be combined to perform composite operations involving data from both devices. The connection can expire after a period of inactivity and require physical proximity to be established to prevent unwanted access to the MFD. Such an approach establishes a shared extensibility framework for the multifunction device and the mobile communications device as a single execution environment.Type: GrantFiled: February 13, 2013Date of Patent: September 27, 2016Assignee: Xerox CorporationInventors: Gavan Tredoux, Phillip Emmett, Premkumar Rajendran, Peter Zehler

Publication number: 20160127585Abstract: A portable computing device is connected to another device that has an optical scanner and a facsimile modem. An application on the portable computing device causes the optical scanner to scan an item and causes the separate device to transmit the electronic image of the scanned item to the portable computing device. The application receives facsimile information into a graphic user interface of the portable computing device. Then, the application creates a facsimile file by combining the electronic image and the facsimile information. The facsimile file is transmitted to the separate device, and the application causes the separate device to send the converted electronic image as a facsimile using the facsimile information contained within the facsimile file. The portable computing device receives the result of the attempt to send the facsimile from the separate device, and this result is displayed on the graphic user interface of the portable computing device.Type: ApplicationFiled: October 30, 2014Publication date: May 5, 2016Inventors: MICHAEL H.
