Patent number: 9773173Abstract: A method and apparatus for screening luggage are provided. X-ray images derived by scanning the luggage with X-rays are received and processed with an automated threat detection (ATD) engine. A determination is then made whether to subject respective ones of the X-ray images to further visual inspection by a human operator at least in part based on results obtained by the ATD engine. In certain cases, visual inspection by a human operator is by-passed and the ATD results are relied upon in order to mark luggage for further inspection or to mark luggage as clear. In another aspect, X-ray images derived by scanning the luggage using two or more X-ray scanning devices are pooled at a centralized location. ATD operations are applied to the X-ray images, which are then provided “on-demand” to a human operator for visual inspection. Results of the visual inspection are entered by the human operator and then conveyed to on-site screening technicians associated with respective X-ray scanning devices.Type: GrantFiled: March 4, 2015Date of Patent: September 26, 2017Assignee: Optosecurity Inc.Inventor: Luc Perron

Patent number: 9194975Abstract: A method, an apparatus and a system are provided for determining if a piece of luggage contains a liquid product comprised of a container holding a body of liquid. The piece of luggage is scanned with an X-ray scanner to generate X-ray image data conveying an image of the piece of luggage and contents thereof. The X-ray image data is processed with a computer to detect a liquid product signature in the X-ray image data and determine if a liquid product is present in the piece of luggage. A detection signal is released at an output of the computer conveying whether a liquid product was identified in the piece of luggage. The detection signal may, for example, be used in rendering a visual representation of the piece of luggage on a display device to convey information to an operator as to the presence of a liquid product in the piece of luggage.Type: GrantFiled: September 25, 2014Date of Patent: November 24, 2015Assignee: OPTOSECURITY INC.Inventors: Stephane Drouin, Regis Poulin, Luc Perron, Dan Gudmundson

Patent number: 9170212Abstract: A method, an apparatus and a system are provided for assessing at a security checkpoint the threat status of a liquid product comprised of a bottle at least partially filled with liquid. Generally, an X-ray image of the liquid product is obtained and processed to derive a level of fill of the bottle and the threat status of the liquid product is determined at least in part based on the level of fill of the bottle. In some examples presented, an X-ray image of the liquid product is processed to derive location information associated with a meniscus formed by the liquid in the bottle and an estimated length of a path followed by X-rays through the liquid held in the bottle is used to determine the threat status of the liquid product, the length of the path being derived in part based on the location information.Type: GrantFiled: April 3, 2014Date of Patent: October 27, 2015Assignee: OPTOSECURITY INC.Inventors: Michel Bouchard, Dan Gudmundson, Eric Bourbeau

Patent number: 8867816Abstract: A method, an apparatus and a system are provided for assessing at a security checkpoint the threat status of a liquid product, where the liquid product is comprised of a bottle at least partially filled with liquid. In accordance with a broad aspect, the level of fill is used as a factor in the determination of the threat status of the liquid product. In accordance with another broad aspect, an X-ray image of the liquid product is obtained and processed to derive a level of fill of the bottle and the threat status of the liquid product is determined at least in part based on the level of fill of the bottle. In accordance with yet another broad aspect, an X-ray image of the liquid product is processed to derive location information associated with a meniscus formed by the liquid in the bottle. An estimated length of a path followed by X-rays through the liquid held in the bottle is derived in part based on the location information and is used to determine the threat status of the liquid product.Type: GrantFiled: March 27, 2009Date of Patent: October 21, 2014Assignee: Optosecurity Inc.Inventors: Michel Bouchard, Dan Gudmundson, Eric Bourbeau

Patent number: 8831331Abstract: A method, an apparatus and a system are provided for deriving a characteristic of a product using X-rays. X-ray image data associated with the product is received, the X-ray image data being derived by performing an X-ray scan of the product using an X-ray imaging apparatus and conveying attenuation information resulting from interaction of X-rays with the product. A response of a reference product to X-rays is then simulated to generate simulated X-ray image data. The simulated X-ray image data and the received X-ray image data are then processed to derive one or more characteristics of the product. Information conveying the derived characteristic of the product is then released. In a specific implementation, the product is a liquid product comprised of a bottle at least partially filled with liquid and the derived characteristic of the liquid product is a threat status assessment associated with the liquid in the bottle.Type: GrantFiled: June 9, 2009Date of Patent: September 9, 2014Assignee: Optosecurity Inc.Inventors: Dan Gudmundson, Eric Bourbeau, Luc Perron

Patent number: 8494210Abstract: An apparatus, method and system for facilitating visual identification of a prohibited object in an image during security screening are provided. Data derived from an apparatus that scans the receptacle with penetrating radiation conveying an image of the contents of a receptacle is received. Information from an automated threat detection processor is also received and indicates an area of interest in the image potentially containing a prohibited object. The image is then processed to generate an enhanced image. In a first example, portions of the enhanced image outside the area of interest are visually de-emphasized. In a second example, features appearing inside the area of interest are visually emphasized. The enhanced image is then displayed on a display device. Optionally, thumbnail images associated with previously screened receptacles are displayed and a user is enabled to select one or more thumbnail images. An enhanced image corresponding to the selected thumbnail image is then displayed.Type: GrantFiled: March 30, 2007Date of Patent: July 23, 2013Assignee: Optosecurity Inc.Inventors: Dan Gudmundson, Luc Perron
