  • Patent number: 9578617
    Abstract: A system for measuring in an anonymous manner one or more spatial positions of one or more user devices within a region, wherein the system includes a wireless arrangement for receiving signals from the one or more user devices for determining the one or more spatial positions of the one or more user devices, wherein the wireless arrangement is operable to receive one or more user identification codes from the one or more user devices, wherein the one or more user identification codes include N bits; the system is operable to apply a mapping function to map the one or more user identification codes to form one or more corresponding secondary identification codes by decreasing an entropy of the one or more user identification codes by K bits; and the system is operable to modify the one or more corresponding secondary identification codes by increasing entropy of the one or more corresponding secondary identification codes by M bits.

  • Patent number: 9420430
    Abstract: A method and system for verifying an indoor position using Wireless Local Area Networks (WLAN), access points (AP), and Assisted Global Positioning System (A-GPS). The goal of this method is to determine if a user is in the place where he claims to be by using a mobile device. When a user wants his location to be verified he activates a scanning process on his mobile device that reads all the requested signals (WLAN, A-GPS). When the recording process is complete the information is sent to a server where it is processed and the user location is either confirmed to be true or false.

  • Patent number: 9167554
    Abstract: The present disclosure provides a method and system for tracking one or more portable communication devices in a radio communication network in a facility. The system comprises two or more sensors and a server. Each of the two or more sensors is configured to record a radio signal strength corresponding to each of one or more radio signal probes from each of the one or more portable communication devices, by utilizing a corresponding media access control address of each of the one or more portable communication devices. The server is configured to determine a location coordinate of each of the one or more portable communication devices using the recorded radio signal strengths and an adaptive supervised machine learning system. A learning cycle of the adaptive supervised machine learning system is configured to initiate when a variation in one or more technical attributes of the radio communication network in the facility is detected.

  • Patent number: 9063208
    Abstract: A method and a system for accurately positioning an electronic device located in an indoor area, generates a request signal for determining the indoor location of the device, and sends the signal to a server coupled to the device through a network. The request signal contains certain parameters pertaining thereto, including the signal strength, and the information of the cell towers through which the device sent the signal. The server uses the signal parameters to determine information pertaining to an approximate spatial position of the device, and sends and information to the device. Multiple positioning algorithms are embedded in the computing hardware of the device, and the device executes these algorithms to determine the exact indoor location thereof.
