20080260350 | Audio Video Synchronization Stimulus and Measurement - The present invention uses artificially generated unobtrusive audio and video synchronization events, which are essentially undetectable by normal human viewers, to send audio and video synchronization information by encoding audio and video events in normal program audio and video datastreams. By proper generation of unobtrusive audio and video synchronization events, and by proper use of modern electronics and software to automatically extract such unobtrusive synchronization events from audio and video signals, audio and video synchronization can be nearly continually provided, despite many rapid shifts in cameras and audio sources, without generating obtrusive events that distract the viewer or detract from the actual program material. At the same time, because such unobtrusive synchronization signals can be carried by standard (preexisting) audio and video transmission equipment, the improved unobtrusive synchronization technology of the present invention can be easily and inexpensively implemented because it is backward compatible with the large base of existing equipment. | 10-23-2008 |

20090208127 | SPATIAL SCAN REPLICATION CIRCUIT - In an image replication circuit, the improvement of replicating a given element at a certain location with the most similar of surrounding sets of image elements. | 08-20-2009 |
20090251600 | AV Timing Measurement for MPEG Type Television - An invention for measuring, maintaining and correcting synchronization between signals which suffer varying relative delays during transmission and/or storage is shown. The preferred embodiment of the invention finds particular use in measuring the relative delay between multiple audio signals and an associated video signal of a television type program which is compressed via MPEG or other compression for a transmission and/or storage system. The invention marks the video signal at a time when a particular event in the associated audio occurs. The mark is carried with the video throughout the video processing. After processing the same event in the audio is again identified, the mark in the video identified, the two being compared to determine the timing difference therebetween. | 10-08-2009 |
20100247065 | PROGRAM VIEWING APPARATUS AND METHOD - Improvements in program viewing apparatus and methods, some of which are now commonly referred to as personal video recorder (PVR) and program guide features in television sets, set top boxes and other video devices. The invention provides for a user display such as a flat panel program display device, a user remote for the user to control operations and features, program data storage for storing programs and related information, removable data storage for storing programs and related information on removable storage media. Also included is a data manager which functions include response to the user's desires via the user remote to control receiving and storing programs and select received or stored programs to be displayed on the user display device. The data manager may also be responsive to receive, store and display other services such as programming guide services to provide enhanced program viewing and storage management as directed by the user. | 09-30-2010 |
20110028184 | Universal Credit Card Apparatus and Method - The apparatus and method described herein provides for creating multiple spatial patterns, such as magnetic patterns on credit cards. The invention includes storage of information from which patterns may be created, a pattern creation device for creating the spatial patterns, and control whereby the information which is stored is selectively utilized to cause the pattern creation. This allows multiple desired patterns to be simulated, allowing convenient replacement of a number of separate pattern carrying devices. | 02-03-2011 |
20120041762 | Dialogue Detector and Correction - An apparatus and method for tracking dialogue and other sound signals in film, television or other systems with multiple channel sound is described. One or more audio channels which is expected to carry the speech of persons appearing in the program or other particular types of sounds is inspected to determine if that channel's audio includes particular sounds such as MUEVs, including phonemes corresponding to human speech patterns. If an improper number of particular sounds such as phonemes are found in the channel(s) an action such as a report, an alarm, a correction, or other action is taken. The inspection of the audio channel(s) may be made in conjunction with the appearance of corresponding images associated with the sound, such as visemes in the video signal, to improve the determination of types of sounds such as phonemes. | 02-16-2012 |
20120127365 | Delay and Lip Sync Tracker - A delay tracker utilizes a special code on the tracked signal in order to recognize such signal and ascertain any delays associated therewith. | 05-24-2012 |
20140146230 | AV Timing Measurement and Correction for Digital Television - An invention for measuring, maintaining and correcting synchronization between signals which suffer varying relative delays during transmission and/or storage is shown. The present invention teaches measuring the relative delay between a plurality of signals which have suffered differing delays due to transmission, storage or other processing. The preferred embodiment of the invention includes the use of a marker which is generated in response to a second signal and combined with a first signal in a manner which ensures that the marker will not be lost in the expected processing of the first signal. Subsequently a first delayed marker is generated in response to the marker associated with or recovered from the first signal, and a second delayed marker is generated from the second signal. The first delayed marker and second delayed marker are compared to determine a measure of the relative timing or delay between said first signal and said second signal at said subsequent time. | 05-29-2014 |
20140166323 | Kickback Reduction for Power Tools and Machines - An apparatus and methods are described for protecting an operator from sudden, unexpected or dangerous movement of powered hand held tools and the like. A set of parameters for safe operation of the tool are provided, which parameters may be adjusted or selected based on the manner in which the tool is being operated. The power tool is fitted with sensors including an accelerometer, operating to sense acceleration of the tool in a plurality of axes during operation. The output of the accelerometer is coupled to a computing circuit which determines if the acceleration of the tool is within the safe operation parameters. When acceleration of the tool exceeds one or more of the safe operating parameters, power to the tool motor is limited or otherwise adjusted in order to prevent or reduce the movement of the tool thereby protecting the operator. | 06-19-2014 |
