Patent number: 8005267Abstract: An apparatus for the automatic inspection of a motor vehicle has an identification and psychological profiling zone, an automatic inspection zone and a manual inspection zone. A biometric and heart rate detection station and an attached console are located in zone one. Undercarriage scanning equipment and an explosives detection portal are located in zone two. The apparatus also has one or more fixed cameras, an alarm or other alerting mechanisms and a physical barrier. A vehicle detection mechanism detects the entry of a vehicle into zone two and captures an image of the vehicle number plate. When the captured biometric data and number plate data indicate that the driver is authorized to drive the particular vehicle into the secured zone, and if no abnormalities or foreign objects in the undercarriage image are detected, the driver is allowed to proceed.Type: GrantFiled: October 16, 2008Date of Patent: August 23, 2011Assignee: Stratech Systems LimitedInventor: Khien Meow David Chew

Patent number: 7889232Abstract: A surveillance system and method for vessels. The system comprises surveillance means for surveying a waterway; vessel detection means for determining the presence and location of a vessel in the waterway based on information from the surveillance means; camera means for capturing one or more images of the vessel; image processing means for processing the images captured by the camera means for deriving surveillance data; wherein the camera means captures the vessel images based on information from the vessel detection means, the surveillance data from the image processing means, or both. The images can be used to classify and identify the vessel by name and category, possibly also to compare the category with that previously registered for a vessel of this name. The vessel can be tracked, including by speed and direction until it leaves the surveyed waterway.Type: GrantFiled: June 22, 2005Date of Patent: February 15, 2011Assignee: Stratech Systems LimitedInventor: Khien Meow David Chew
