532 results about "Spatial analysis" patented technology

Spatial analysis or spatial statistics includes any of the formal techniques which study entities using their topological, geometric, or geographic properties. Spatial analysis includes a variety of techniques, many still in their early development, using different analytic approaches and applied in fields as diverse as astronomy, with its studies of the placement of galaxies in the cosmos, to chip fabrication engineering, with its use of "place and route" algorithms to build complex wiring structures. In a more restricted sense, spatial analysis is the technique applied to structures at the human scale, most notably in the analysis of geographic data.

System and method of vehicle surveillance

The invention relates to a system and method of conducting surveillance of stolen vehicles. Stolen vehicle information is downloaded from a database to a central server. At the central server, vehicle information is parsed to the specific requirements. Each subscribing jurisdiction downloads its area-specific stolen vehicle database to a subscriber workstation, e.g., via the Internet or an intranet. Police cars have on-board mobile surveillance points having a camera and a processor. A copy of the area-specific stolen vehicle database is loaded into each car's processor. The mobile surveillance point reads license plates of vehicles in traffic, and the processor compares the license plates to stolen plate numbers stored in the database. The processor activates a signal to alert the officer. Stationary checkpoints located in the jurisdiction have a stationary surveillance point having a camera and a processor. The surveillance system stores images and creates a database of all vehicle plates in the area. The surveillance data is downloaded to the subscriber computer. The subscriber computer has a map database. A comparison algorithm identifies stolen vehicles in the area and their direction of travel, and displays the information on an area map. The analysis if performed with a spatial analysis algorithm along with temporal analysis using police officer's experience and knowledge of the area and vehicle types (make / model / value / etc) stolen. The police officer analyzes patterns of stolen vehicles and generates suggested new locations for checkpoints, narrowing in on a possible chop shop location.

An apparatus for determining a propagation velocity for a surface wave comprises a coherent light source (105) for generating at least a first and a second light spot on a surface (103). A camera (111) captures at least one out-of-focus image of at least a part of the surface (103) comprising the light spots. The out-of-focus image comprises light spot image objects for the light spots where the light spot image objects have speckle patterns. An analyzer (113) determines the propagation velocity in response to a time difference between speckle pattern changes in the two speckle patterns. The camera may specifically use a rolling shutter allowing the determination of the propagation velocity to be based on a spatial analysis of the speckle patterns. The approach may in particular allow an efficient remote measuring of pulse wave velocities e.g. in animal tissue and in particular, in human tissue.
