20090141049 | DISPLAY APPARATUS FOR COMPENSATING OPTICAL PARAMETER USING FORWARD VOLTAGE OF LED AND METHOD THEREOF - A display apparatus for compensating an optical parameter, and a display method thereof are disclosed, the display apparatus including a display, an optical source unit, a voltage detection unit which measures the forward voltage of an optical source, and a control unit which controls driving of the optical source unit using a forward voltage of the at least one optical source. Accordingly, the variation of optical parameter is accurately compensated, and the cost for fabricating a temperature sensor and the time for measuring the temperature are reduced. | 06-04-2009 |
20090237327 | METHOD FOR GENERATING SIGNAL TO DISPLAY THREE-DIMENSIONAL (3D) IMAGE AND IMAGE DISPLAY APPARATUS USING THE SAME - A method for generating a signal to display a three-dimensional (3D) image, and an image display apparatus using the same are disclosed. The method includes receiving a first synchronization signal, generating a second synchronization signal, and generating an output signal. Therefore, a user may satisfactorily view a 3D image regardless of whether the synchronization signal received from a display device reports errors or whether there is an obstruction between the display device and shutter glasses. | 09-24-2009 |
20090256812 | DISPLAY APPARATUS AND CONTROL METHOD OF THE SAME - A display apparatus includes a display panel having a light emitting device, a sensor which senses an electric current flowing in the light emitting device, and a controller which determines that an external stimulus occurs to the display panel if a change of a sensed current exceeds a preset current change rate, and performs a predetermined operation on the basis of a determination result. | 10-15-2009 |
20140139653 | METHOD FOR GENERATING SIGNAL TO DISPLAY THREE-DIMENSIONAL(3D) IMAGE AND IMAGE DISPLAY APPARATUS USING THE SAME - A method for generating a signal to display a three-dimensional (3D) image, and an image display apparatus using the same are disclosed. The method includes receiving a first synchronization signal, generating a second synchronization signal, and generating an output signal. Therefore, a user may satisfactorily view a 3D image regardless of whether the synchronization signal received from a display device reports errors or whether there is an obstruction between the display device and shutter glasses. | 05-22-2014 |

20150180894 | DETECTING ANOMALOUS ACTIVITY FROM ACCOUNTS OF AN ONLINE SERVICE - Anomalous activity is detected using event information that is received from accounts from within an online service. Generally, anomalous activity is detected by comparing a baseline profile that includes past event information for accounts of the online service with a recent profile that includes recent event information for the accounts. Anomalous activity is detected when the recent profile shows that one or more events are occurring more frequently as compared to the occurrence of the event the associated baseline profile. The events that are recorded and used in the anomaly detection may include all or a portion of events that are monitored by the online service. One or more reports may also be automatically generated and provided to one or more users to show activity that may be considered anomalous activity. | 06-25-2015 |
20150227595 | END TO END VALIDATION OF DATA TRANSFORMATION ACCURACY - Data is validated as it travels through the different nodes of a data pipeline. Instead of having to wait to validate the data when the data reaches an end of the data pipeline, each node in the pipeline may validate the data. Different methods may be used to validate the data. For example, each node may determine metadata about the received data and/or the transformed data. This metadata may be used to determine if the node is receiving the same amount of data as it usually receives, whether the data is in a same format, and the like. A timing of the data through one or more of the nodes may also be used in determining when the data is valid. When a problem is detected at any of the nodes in the pipeline, a report may be sent to one or more users. | 08-13-2015 |

20100067741 | Real-time tracking of non-rigid objects in image sequences for which the background may be changing - A method and apparatus is disclosed for tracking an arbitrarily moving object in a sequence of images where the background may be changing. The tracking is based on visual features, such as color or texture, where regions of images (such as those which represent the object being tracked or the background) can be characterized by statistical distributions of feature values. The method improves on the prior art by incorporating a means whereby characterizations of the background can be rapidly re-learned for each successive image frame. This makes the method robust against the scene changes that occur when the image capturing device moves. It also provides robustness in difficult tracking situations, such as when the tracked object passes in front of backgrounds with which it shares similar colors or other features. Furthermore, a method is disclosed for automatically detecting and correcting certain kinds of errors which may occur when employing this or other tracking methods. | 03-18-2010 |
20110037311 | Polymorphic tracked behicle - A method and apparatus is disclosed, for construction and operation of an all terrain polymorphic tracked vehicle. The invention improves on the prior art by providing a mechanism whereby it is possible to vary the shapes of the tracks during operation of the vehicle. This capability facilitates negotiating obstacles and rough terrain, enables such vehicles to climb stairs or similar obstacles, and also enables self leveling of the vehicle on inclined terrain. | 02-17-2011 |
20120183383 | Mechanism and method of operation for polymorphic tracked vehicles such that the vehicle's weight can be spread between multiple supporting wheels - A method and apparatus is disclosed, for construction and operation of an all terrain polymorphic tracked vehicle. This invention extends and improves on the prior art disclosed in USPTO patent pending “A polymorphic tracked vehicle”, filed August 2009, USPTO application Ser. No. 12/540,391. The improvement concerns a mechanism and method of operation by which a track mechanism can be polymorphic, but can also distribute the weight of the vehicle over multiple supporting wheels. In contrast, in most configurations of the mechanism disclosed in application Ser. No. 12/540,391, the weight of the vehicle rests on just two wheels per track (i.e. on four wheels if the vehicles possesses a left track and a right track). | 07-19-2012 |
