    摘要: A position detection system is provided in which it is possible to inhibit deterioration in accuracy of detecting a position of a terminal after communication environment is changed even in a case where the communication environment is changed in the position detection system. In the position detection system, a first terminal measures radio wave intensity of radio waves from a plurality of wireless connection devices in the first terminal, and transmits a measurement result to a position detection server through each of the wireless connection devices. A second terminal is disposed in a prescribed position, measures the radio wave intensity of the radio waves from the plurality of wireless connection devices in the prescribed position, generates first reference data including information of the measured radio wave intensity, and transmits the first reference data to the position detection server through the wireless connection devices. The position detection server receives the measurement result and the first reference data, updates the first reference data, which is maintained in a memory in advance, with the received first reference data, and estimates a position of the first terminal based on the measurement result, the updated first reference data, and positional information of the second terminal.

    摘要: A virtual barrier system for determining a position of a mobile device relative to a virtual barrier comprises: a plurality of transmitters configured to broadcast a unique identifier; a management platform for storing positional data for each transmitter; a mobile application for installation on a mobile device. The management platform is configured to communicate with the mobile application. The plurality of transmitters are arranged in pairs, one of each corresponding with a first or second zone. The pairs are positioned to define the virtual barrier between said first and second zones. The management platform is configured to: (a) map the barrier; (b) receive transmitted data from the mobile application when the mobile application detects the unique identifier, and (c) send an alert to the mobile application for display. The first zone and second zone comprise different statuses, and the status of the second zone is dependent upon a specific user.

    摘要: A position detection system is provided which is capable of inhibiting an increase in system costs and improving accuracy of detecting a position of a terminal. In the position detection system, a first terminal measures radio waves from a wireless connection device or a second terminal, and transmits a measurement result to a position detection server through the wireless connection device. The position detection server estimates that the first terminal is located in a position of the second terminal which has transmitted the radio waves in a case where the measurement result includes information of the radio waves from the second terminal, and estimates the position of the first terminal based on information of radio wave intensity of the radio waves from the wireless connection device, which is included in the measurement result, reference data, and positional information of the second terminal in a case where the measurement result does not include the information of the radio waves from the second terminal.

    摘要: Methods for emergency visualization are disclosed. The methods include a computer-implemented method for interactive emergency visualization that includes receiving a notification concerning an incident associated with a multi-floor structure, requesting location information from a user device geographically associated with the multi-floor structure, and receiving, in response to the request, a beacon identifier from the user device, the beacon identifier being associated with a beacon disposed within the multi-floor structure. The method also includes determining on which floor of the multi-floor structure the user device is located based on the beacon identifier and stored information indicating the location of the beacon and displaying a graphical map of the multi-floor structure and information indicating the specific floor on which the user device is located.
