Patent number: 9146300Abstract: Systems, devices, features, and/or methods for determining a location of a mobile device are disclosed. A method may include (a) receiving, into a mobile device, a common RF signal on a common carrier frequency, wherein the common RF signal includes a respective RF signal output by each of three or more transmitters on a common time basis in a round-robin manner, and wherein each of the three or more transmitters is positioned at a known location, (b) capturing data representing the common RF signal, (c) based on the captured data, discriminating between each respective RF signal that forms the received common RF signal, (d) determining a relative phase shift of each respective RF signal, and (e) determining the location of the mobile device based on the determined relative phase shifts and the known locations of the three or more transmitters.Type: GrantFiled: September 14, 2012Date of Patent: September 29, 2015Assignee: HERE Global B.V.Inventor: Charles J.

Patent number: 8965403Abstract: One or more systems, devices, and/or methods for tracking a wireless device are disclosed. For example, a method includes receiving signal strength data for each of a plurality of access points. The signal strength data from the plurality of access points is compared to identify an anchor access point having a highest signal strength. Remaining signal strength data from the plurality of access points are compared to a threshold signal strength to identify at least one attractor access point. A memory is accessed for locations of the anchor access point and the at least one attractor access point. A pull point is calculated along a line from the anchor access point to the at least one attractor access point. A location of the wireless device is estimated as an average of the pull point and the location of the anchor access point.Type: GrantFiled: August 14, 2013Date of Patent: February 24, 2015Assignee: HERE Global B.V.Inventor: Charles J.

Patent number: 7136915Abstract: A communications system to post arbitrary information to any geographical region simply by outlining the region on a map in the system's user interface and attaching the information to the outlined region is provided. The outlined region can be of any size, e.g., a city block, a neighborhood, a county, and defines the information's “region of relevance”. Any user of the system can also browse and receive these geographically relevant postings simply by identifying a point or region of interest on one of the system's maps. Uses of the system range from personal communication of questions and announcements to a geographically identified group, to governmental and commercial news and announcements aimed at a particular population, to “virtual billboards” for advertising.Type: GrantFiled: December 26, 2001Date of Patent: November 14, 2006Inventor: Charles J Rieger, III

Patent number: 6654800Abstract: An HTTP server connected to the World Wide Web is described. The system allows a user to post arbitrary information to any geographical region simply by outlining the region on a map in the system's graphical user interface and attaching the information to the outlined region. Any user of the system can browse and receive these geographically relevant postings simply by identifying a point or region of interest on one of the system's maps. Users with registered accounts can elect to receive automatic email of postings that are relevant to one or more of their primary geographical coordinates. Mobile users can condition their cell phones or other communications devices to check into the system periodically to receive geographically relevant postings as they travel. The system can be used for communications with a geographically identified group, for governmental and commercial communications with a particular population, and for advertising, among other uses.Type: GrantFiled: March 14, 2000Date of Patent: November 25, 2003Inventor: Charles J.
