Abstract: A system and method for graphical representation of spatial data. A disclosed video display system is capable of presenting a layout of graphics objects as part of a displayed image. The system provides in the displayed image i) a first graphical representation in a first display area of a display and ii) a diagrammatic representation in a second display area. The diagrammatic representation features superimposed graphical elements that are dependent on the first graphical representation. The video display system can provide, for example, a pie chart as the first graphical representation and a map of a geographic area as the diagrammatic representation. The pie chart graphically represents, for example, a breakdown of members by organization, wherein each slice in the pie chart corresponds to a different organization. Superimposed on the map are elements of a bar chart, which is another example of a graphical representation.

Abstract: A system and method for ray launching in electromagnetic wave propagation modeling. A data-processing system receives a dataset that is representative of one or more structures within an environment, including a structure that is defined in the dataset as having at least a first surface. The data-processing system establishes a bounding box that is representative of the first surface and partitions at least a portion of the bounding box into a first set of tiles. The data-processing system then projects a first set of ray tubes from a predetermined point within the environment, to the tiles in the first set of tiles. Each ray tube in the first set of ray tubes is defined by a corresponding tile in the first set of tiles. The data-processing system evaluates the incidence of bounced ray tubes at a predetermined receive point within the environment and presents a propagation result that is based on the evaluated incidence.

A disclosed video display system is capable of providing, as part of a displayed image, i) a collection of data points in a first display area of a display and ii) a first graphical representation in a second display area, wherein the graphical elements in the first graphical representation are dependent on the collection of data points. The video display system can provide, for example, a scatter plot as the collection of data points and a pie chart as the first graphical representation, and can superimpose a selection window on the scatter plot, in order to enable a user to specify or select a subset of the data points. The pie chart graphically represents, for example, a breakdown of members by organization, wherein each slice in the pie chart corresponds to a different organization.

Abstract: A method using Infrared Imaging Polarimetry for detecting the presence of foreign fluids on water comprises estimating an expected polarization response for a foreign fluid desired to be detected. Oil from an oil spill is one such foreign fluid. An optimal position of a polarimeter to take images of the water's surface is determined from the expected polarization response. The polarimeter is positioned at the optimal position and records raw image data of the water's surface to obtain polarized images of the area. The polarized images are corrected, and IR and polarization data products are computed. The IR and polarization data products are converted to multi-dimensional data set to form multi-dimensional imagery. Contrast algorithms are applied to the multi-dimensional imagery to form enhanced contrast images, from which foreign fluids can be automatically detected.

Abstract: A disclosed location engine estimates a wireless terminal as being indoors or outdoors by utilizing information that includes metadata from previous packet-level transmissions involving both i) wireless terminals that are known to have been indoors and ii) wireless terminals that are known to have been outdoors, while the metadata was collected. Based on this metadata for previous transmissions, one or more classification features are computed. Then, for a wireless terminal that is to be classified during a communication transaction (e.g., voice, data, SMS, etc.) with respect to the terminal being either indoors or outdoors, features that are representative of that wireless terminal for the transmissions are evaluated against a characterization that is a composite of one or more previously-computed classification features. The features that are representative of the wireless terminal can be derived from the metadata associated with the wireless terminal during the transaction being analyzed.

Abstract: Data from a wireless network location system is used in conjunction with the known geographic location of a video surveillance area such that the system according to the present invention infers that a person who appears in an image in the video is the user of a mobile phone estimated to be at the person's location. When facial recognition is applied and the person's identity is thus recognized, an association is generated as between the identity according to the facial recognition and the identity of the co-located mobile phone. This association can be critical when there is no personal identification available for a mobile phone such as a pre-paid mobile.
