Publication number: 20090232473Abstract: An apparatus and method is presented for receiving and displaying user messages associated with multimedia content. Specifically, the present invention is directed to controlling the operation of a television recording/playback system to permit a user to input a message, associate that message with a selected television program, and display the associated message when the selected television program is accessed by another user (see FIG. 1). The apparatus of the present invention is directed to a system for managing multimedia content including devices for storing television programs and associating with those programs user-generated messages for display to other system users. In this way, the present invention provides content management tools that promote sharing by all users, ease the process of establishing a consensus for managing limited resources, and encourage monitoring by the administrator.Type: ApplicationFiled: June 12, 2006Publication date: September 17, 2009Applicant: THOMSON LICENSINGInventors: Scott Allan Kendall, Gavin Lee Johnston

Patent number: 7444657Abstract: A television signal receiver having an emergency alert function provides a masked list of emergency events during a user setup process for the emergency alert function which makes the setup process easier for users, and also ensures that the emergency alert function will be activated when certain important emergency events occur. According to an exemplary embodiment, the television signal receiver includes a memory operative to store data associated with the emergency alert function. A processor is operative to receive an input representing a geographical area and to enable generation of a masked list of emergency events responsive to the input using the data in the memory. The masked list of emergency events represents a subset of all emergency events associated with the emergency alert function.Type: GrantFiled: June 26, 2003Date of Patent: October 28, 2008Assignee: Thomson LicensingInventors: Scott Allan Kendall, Gavin Lee Johnston, John D Merrell

Publication number: 20080122988Abstract: An apparatus (20) such as a television signal receiver provides an emergency alert function that avoids interrupting a user's program viewing and/or listening activities when the emergency alert function is activated, but still allows the user to be informed regarding emergency events. According to an exemplary embodiment, the apparatus (20) includes a first tuner (22a) operative to tune a first channel including an emergency alert signal. A second tuner (22b) is operative to tune a second channel including at least one of audio and video content. A third tuner (22c) is operative to tune a third channel including at least one of audio and video content responsive to the emergency alert signal.Type: ApplicationFiled: December 13, 2005Publication date: May 29, 2008Inventor: Gavin Lee Johnston

Publication number: 20070091648Abstract: A mechanism for reducing common-mode current in a system including a first subsystem and an isolated subsystem. The isolated subsystem may receive the common-mode current from the first subsystem via an isolation mechanism. The isolation mechanism (e.g., a transformer) may isolate the isolated subsystem from the first subsystem by blocking DC signals. The first subsystem may include a pulse generation unit and compensation circuitry. The pulse generation unit may provide a first pulse and a second pulse to the compensation circuitry. The phase and duty cycle of the pulses may be varied based on measured characteristics of the isolation mechanism. The compensation circuitry may generate a cancellation signal based on the first and second pulses. Furthermore, the compensation circuitry may provide the cancellation signal to a ground plane of the isolated subsystem to reduce the common-mode current received at the isolation subsystem.Type: ApplicationFiled: October 21, 2005Publication date: April 26, 2007Inventor: Lee Johnston

Patent number: 7100886Abstract: Apparatus and methods are disclosed for making masonry blocks with one or more surfaces having a roughened texture resembling that of a split block or natural stone. In one embodiment, a mold comprises a plurality of walls defining at least one mold cavity adapted to receive block-forming material. The mold defines an opening through which a formed, uncured block may be removed from the mold. At least one wall of the mold has a plurality of projections extending into the mold cavity so as to contact an adjacent surface of the uncured block in the mold cavity. The projections are positioned such that when the uncured block is removed from the mold, the projections texture the adjacent surface of the uncured block.Type: GrantFiled: March 4, 2002Date of Patent: September 5, 2006Assignee: Westblock Systems, Inc.Inventors: James Hammer, Llewellyn Lee Johnston
