Patent number: 11373511Abstract: A system and method for processing alarms includes receiving alarm data from a third-party data source, the alarm data having visual data, an area of interest, and a sought target. The system processes the visual data to detect an object in the area of interest, and then classifies the object either in conformance with the sought target or in nonconformance with the sought target. The system issues a positive alarm when the object is in conformance with the sought target, and issuing issues a false alarm when the object is in nonconformance with the sought target. Feedback is received from the third-party data source regarding an accuracy of the respective positive alarm and the false alarm.Type: GrantFiled: September 14, 2021Date of Patent: June 28, 2022Assignee: PureTech Systems Inc.Inventors: Larry J. Bowe, Jr., Monroe M. Thomas, Marvin Wade Barnes, Andrew Giles Tillman, Brant Buchika

Patent number: 11288517Abstract: A system and method detects falling incidents on structures such as cruise vessels, oil rigs, overpasses, and buildings, and also detects overboarding movements onto structures such as cargo ships. The system includes at least two opposed imaging devices which record video streams of a detection cuboid within an overlapping region of view volumes for the imaging devices. The imaging devices monitor objects that pass through the cuboid. Identified objects within the video streams are paired, their conformance is determined, and real-world information such as size, trajectory, and location is determined.Type: GrantFiled: September 1, 2021Date of Patent: March 29, 2022Assignee: PureTech Systems Inc.Inventors: Brant Buchika, Marvin Wade Barnes, Fereydoun Maali

Patent number: 10922552Abstract: A system and method for detecting a man overboard incident on structures such as cruise vessels and oil rigs. The system includes at least two opposed imaging devices which record video streams of a detection cuboid within an overlapping region of view volumes for the imaging devices. The imaging devices are located at the lowest deck of the structure and monitor a fall that passes through the cuboid. Identified objects within the video streams are paired, their conformance is determined, and real world information such as size, trajectory, and location is determined.Type: GrantFiled: February 10, 2017Date of Patent: February 16, 2021Assignee: PureTech Systems, Inc.Inventors: Fereydoun Maali, Marvin Wade Barnes

Patent number: 8929603Abstract: An autonomous lock-on target tracking system and method with geospatial-aware PTZ cameras includes a camera imaging a terrain space. The camera acquires images, and first and second images are aligned. A frame-differencing operation produces a resultant image including blobs corresponding to elements in the terrain space. One of the blobs is classified as an object and tracked as a target. The target is tracked by determining the distance between a centroid of the target and a center of a field of view of the camera, and instructing the camera to move through the distance. The distance is continually updated as the camera and the target move.Type: GrantFiled: March 17, 2014Date of Patent: January 6, 2015Assignee: PureTech Systems, Inc.Inventors: Fereydoun Maali, Dilip Swaminathan, Marvin Wade Barnes

Patent number: 8599261Abstract: Method and apparatus for counting vehicles at entrances, exits and transition zones of multi-story carparks, including particularly where the ceiling heights can be just marginally higher than the tallest expected vehicle, with a view to determine the carpark occupancy at different carpark levels by counting passing vehicles using a vision-based car counting system without relying on viewing test patterns or employing a blocking beam scheme and yet tolerating vehicles transgressing partially or fully into the wrong lane of a two-lane two-way road while ignoring vehicles moving opposite to the expected direction. Without imposing additional constraints to ambient carpark illumination, the methodology copes with highly specular vehicle surfaces, ignores non-vehicular objects and detects moving cast shadow or highlight, and adapts to daily and seasonal scene changes, and yet estimates vehicle speed.Type: GrantFiled: November 20, 2012Date of Patent: December 3, 2013Assignee: PureTech Systems, Inc.Inventor: Fereydoun Maali

Patent number: 8564643Abstract: A method for constructing a georeferencing-enabled camera model and its deployment in georeferencing targets located in video sequences due to a single video camera. A video surveillance camera is modeled by a collection of rays converging at a virtual camera point and the retina resolution cell coordinates associated with those rays wherein the ray equations are first established, in the course of a calibration process, for a given camera view, with the aid of other views of the same video surveillance camera, as necessary, and using such a model for mapping image coordinates to terrain coordinates and vice versa in the intended view or its adaptation for use in other views of the same video surveillance camera.Type: GrantFiled: July 26, 2012Date of Patent: October 22, 2013Assignee: Puretech Systems Inc.Inventors: Fereydoun Maali, Monroe M. Thomas

Patent number: 5087420Abstract: An improved infectious waste treatment system wherein infectious waste is fragmented and converted to a liquid or liquid/sludge form and then is chemically disinfected in a precisely controlled and timed batch process. The disinfection process takes place in an airtight sealed container to insure against release of pathogenic agents into the atmosphere. The process produces a non-toxic and non-infectious liquid or liquid/sludge waste residue which can be safely released into a sanitary sewer, landfilled or otherwise environmentally disposed.Type: GrantFiled: October 14, 1988Date of Patent: February 11, 1992Assignee: Puretech Systems, Inc.Inventor: Edward E.
