Abstract: Geolocating one or more emitters includes obtaining a set of lines of bearing (LOBs) indicative of location(s) of emitter(s), determining intersections of LOBs of the set and generating clusters informed by those intersections, assigning the LOBs of the set to cluster(s) based on proximity, identifying a cluster having the greatest number of assigned LOBs from the set; determining an emitter location area based on a best point estimate for the cluster, and indicating a location of an emitter as the emitter location area. Additional emitters can be located by removing from the set of LOBs those LOBs assigned to the identified cluster, and repeating aforementioned aspects. Initially, the set of LOBs can be selected from a larger collection as a representative subset thereof.

Abstract: The present invention is directed toward a prefabricated shower curb system for easily providing a shower area with a water-retaining curb. The prefabricated shower curb system is formed mainly by a body that has a C-shape and includes a recess, and that is preferably manufactured from a rigid foam material such as expanded polystyrene. The body is mounted onto a wood, aluminum, or other support member arranged along a shower floor entrance area. The support member is secured to the shower walls or to an adjacent support member through brackets. A waterproof liner is used to cover and protect the support member. An adhesive material and the tapered interior design of the body recess allow the curb to be firmly secured in place on the supper member. The extraordinary strength, light-weight, low-cost, and easiness of size adjustment make the system novel in the industry.
