An interactive map web-based tool is provided which gives the user the ability to customize their use of a map. The present invention includes a customized overlay of point of interest information on an existing map. The information overlay includes icons, drop down lists, information panels, advertising content, pop-up windows and hypertext links which are associated with points of interest, where each point of interest is associated with a class. Drop down lists permit the user to display one or more points of interest by location or class. Visual cues, including color coding, icon shaping and text differentiation for different classes of points of interest allow a user of the map to quickly differentiate area resources. With such an arrangement a traveler can easily select for display only those particular resources that are of interest to the traveler and thereby create a local search experience focused on their specific travel needs.

An image based obstacle detection method. A camera mounted on a vehicle provides a set of image frames whilst the vehicle is in motion. The image frames define an image plane having a vertical aspect and a horizontal aspect. The relevancy of an object is determined by (i) selecting first and second feature points from the object that are spaced apart vertically in a first image frame; (ii) tracking the positions of the first and second feature points over at least a second image frame; and (iii) deciding the object to be relevant if the first and second feature points move dissimilar distances in physical space, within a tolerance, and deciding the object to be irrelevant otherwise. The motion of relevant objects is then estimated to determine if any relevant object is likely to become an obstacle to the vehicle.

A method for separating microorganisms, especially infectious agents, from a mixture by two dimensional centrifugation on the basis of sedimentation rate and isopycnic banding density, for sedimenting such microorganisms through zones of immobilized reagents to which they are resistant, for detecting banded particles by light scatter or fluorescence using nucleic acid specific dyes, and for recovering the banded particles in very small volumes for characterization by mass spectrometry of viral protein subunits and intact viral particles, and by fluorescence flow cytometric determination of both nucleic acid mass and the masses of fragments produced by restriction enzymes. The method is based on the discovery that individual microorganisms, such as bacterial and viral species, are each physically relatively homogeneous, and are distinguishable in their biophysical properties from other biological particles, and from non-biological particles found in nature. The method is useful for distinguishing infections, for identifying known microorganisms, and for discovering and characterizing new microorganisms. The method provides very rapid identification of microorganisms, and hence allows a rational choice of therapy for identified infectious agents. A particularly useful application is in clinical trials of new antibiotics and antivirals, where it is essential to identify at the outset individuals infected with the targeted infectious agent.
