Patent number: 10750132Abstract: An automated security surveillance system determines a location of a possible disturbance and adjusts its cameras to record video footage of the disturbance. In one embodiment, a disturbance can be determined by recording audio of the nearby area. A system, coupled to a camera, may include an arrangement of four audio sensors recording audio of the nearby area to produce independent outputs. The system further may include a processing module configured to determine an angle and distance of an audio source relative to a location of the arrangement of the four audio sensors. The system can then adjust the camera by rotation along an azimuth or elevation angle and adjusting the zoom level to record video of the audio source. Through use of the system, a surveillance system can present an image of a source of possible disturbance to an operator more rapidly and precisely than through manual techniques.Type: GrantFiled: March 14, 2013Date of Patent: August 18, 2020Assignee: PELCO, INC.Inventors: Chien-Min Huang, Wei Su, Farzin Aghdasi, James G.

Patent number: 10138987Abstract: A speed reducer used in a server is disclosed to include a first planetary gear set, a planet gear carrier, an internal gear surrounding the first planetary gear set, and an output gear. The first planet gear includes a first sun gear mounted on the motor output shaft, at least one first planet gear pivotally coupled at the first planet gear carrier and meshed with the first sun gear and the internal gear for driving the first planet gear carrier and the output gear to rotate. Thus, the first planetary gear set reduces the revolving speed of the rotary driving force outputted by the motor output shaft, and effectively transfer the rotary driving force to the output gear, achieving the advantages of low backlash and long service life, reducing power transfer loss, increasing server output torque, and providing high speed ratio, high design flexibility and high assembly yields.Type: GrantFiled: April 26, 2016Date of Patent: November 27, 2018Assignee: TRICORE CORPORATIONInventors: Yen-Fu Chen, Chien-Min Huang, Chun-Han Chen

Patent number: 9560323Abstract: An embodiment of the present invention includes a master camera that may record master metadata regarding an object of interest and communicate the master metadata to a slave camera. The slave camera may zoom, pan, or tilt to isolate and record more detailed image data regarding the object of interest based on the master metadata. In addition, the slave camera may record slave metadata regarding the object of interest. The master and slave metadata may be stored associated with the recorded image data enabling a later search for the object of interest to be expedited. The recorded image data including the object of interest may be identified with greater ease as it may be guided by the master or slave metadata, or a combination thereof. According to embodiments presented herein, processing time for searching and identifying an object of interest may be reduced by enabling a search on the metadata associated with image data, rather than by searching the image data itself.Type: GrantFiled: November 12, 2015Date of Patent: January 31, 2017Assignee: Pelco, Inc.Inventors: Chien-Min Huang, Farzin Aghdasi, Hongwei Zhu, Lei Wang, Zhan Jiang Ma

Patent number: 9497388Abstract: Systems, methods, and devices are disclosed for determining a zooming factor for a camera in a pan, tilt, and zoom (PTZ) camera tracking system to enable a camera to keep an object at a constant size within the camera's viewing area, despite changes in the object's distance from the camera. This provides a complement to a camera's pan and tilt tracking of the moving object. For example, a PTZ camera tracking system that determines an object to track, utilizes information regarding images of the object of interest are used to determine a zooming factor (or other zooming value) for a camera in the PTZ camera tracking system. This information includes variables such as tilt angles of one or more cameras and a reference zooming factor.Type: GrantFiled: December 17, 2010Date of Patent: November 15, 2016Assignee: PELCO, INC.Inventor: Chien-Min Huang

Patent number: 9319635Abstract: Network cameras employing advanced video analytics are increasingly being used in both public and private settings. Unlike fixed surveillance cameras, pan/tilt/zoom cameras provide a dynamic field-of-view. Some regions within a given field-of-view can be designated as private and may not be recorded. A window-blanking feature, according to an embodiment of the invention, enables an ability to block out defined portions of the video where a privacy zone may otherwise appear. Through use of the embodiment, consistent privacy is provided during dynamic surveillance to ensure compliance with privacy regulations or contractual arrangements relating to use of a surveillance camera having a privacy zone within the given field-of-view.Type: GrantFiled: November 30, 2012Date of Patent: April 19, 2016Assignee: Pelco, Inc.Inventors: Chien-Min Huang, Farzin Aghdasi, Zhan Jiang Ma

Patent number: 9049447Abstract: Techniques are discussed for providing mechanisms for coding and transmitting high definition video, e.g., over low bandwidth connections. In particular, foreground-objects are identified as distinct from the background of a scene represented in a plurality of video frames received from a video source, such as a camera. In identifying foreground-objects, semantically significant and semantically insignificant movement (e.g., repetitive versus non-repetitive movement) is differentiated. Processing of the foreground-objects and background proceed at different update rates or frequencies.Type: GrantFiled: December 30, 2010Date of Patent: June 2, 2015Assignee: Pelco, Inc.Inventors: Greg Millar, Farzin Aghdasi, Lei Wang, Chien-Min Huang
