Publication number: 20120170803Abstract: Embodiments of the disclosure provide for systems and methods for creating metadata associated with a video data. The metadata can include data about objects viewed within a video scene and/or events that occur within the video scene. Some embodiments allow users to search for specific objects and/or events by searching the recorded metadata. In some embodiments, metadata is created by receiving a video frame and developing a background model for the video frame. Foreground object(s) can then be identified in the video frame using the background model. Once these objects are identified they can be classified and/or an event associated with the foreground object may be detected. The event and the classification of the foreground object can then be recorded as metadata.Type: ApplicationFiled: December 30, 2010Publication date: July 5, 2012Applicant: Pelco Inc.Inventors: Greg Millar, Farzin Aghdasi, Lei Wang

Publication number: 20120170802Abstract: Trajectory information of objects appearing in a scene can be used to cluster trajectories into groups of trajectories according to each trajectory's relative distance between each other for scene activity analysis. By doing so, a database of trajectory data can be maintained that includes the trajectories to be clustered into trajectory groups. This database can be used to train a clustering system, and with extracted statistical features of resultant trajectory groups a new trajectory can be analyzed to determine whether the new trajectory is normal or abnormal. Embodiments described herein, can be used to determine whether a video scene is normal or abnormal. In the event that the new trajectory is identified as normal the new trajectory can be annotated with the extracted semantic data. In the event that the new trajectory is determined to be abnormal a user can be notified that an abnormal behavior has occurred.Type: ApplicationFiled: December 30, 2010Publication date: July 5, 2012Applicant: Pelco Inc.

Patent number: 8173904Abstract: An adapter for use between a two-hole blade end fitting of a line post insulator arm and a Y-clevis bolt eliminates the need to replace the entire insulator arm when the end fitting fails or becomes distorted due to wear of the Y-clevis bolt. The adapter includes a body with a two-hole insulator end that connects to the end fitting and a single or double eye conductor end that supports the Y-clevis bolt. The conductor end is configured to align the load axis of the insulator arm with the Y-clevis bolt to transfer the tension load effectively through the adapter. Annular shoulders surround the two holes in the adapter back and the insulator end of the body. The shoulders extend into the bolt holes in the end fitting to center the bolts and form a clamp on the blade end to prevent further damage to the end fitting.Type: GrantFiled: April 17, 2010Date of Patent: May 8, 2012Assignee: Pelco Products, Inc.Inventors: A.
