A method for managing single function devices among communication devices broadcasting messages to gateways connected to a gateway manager, a single function device being only able to broadcast a message including a command. The method comprises: the gateways receiving messages sent from communication devices, each message containing an identifier of communication device, the gateways determining quality metrics for each received message, the quality metrics pertaining to the radio link between the gateway and the communication device, the gateways storing, for each received message, a property vector comprising the identifier of the communication device and the quality metrics, the gateway manager collecting the property vectors from all the gateways, the gateway manager identifying a single function device by detecting a property vector comprising an identifier of communication device that is included in a list of single function devices, the gateway manager determining a location of the identified single function device based on the quality metrics of the detected property vector, the gateway manager coupling the identified single function device with a feedback device, based on the determined location of the single function device and on a location of the feedback device, and the gateway manager sending an order to the coupled feedback device to perform a feedback signal.

A control device that communicates with a first communication device and a second communication device, the control device comprising: a determination section configured to determine a position of a terminal on a basis of a first ranging result obtained from a radio wave communicated between the first communication device and the terminal and a second ranging result obtained from a radio wave communicated between the second communication device and the terminal, wherein the first communication device is disposed at a first position where it is difficult to directly receive the radio wave between a first area and a second area that are separated by a first member including material through which it is difficult for the radio wave to penetrate, and the second communication device is disposed at a second position where it is difficult to directly receive the radio wave between the first area and the second area.

A method of passive asset tracking using observations of Wi-Fi access points includes associating unique identifying information of a Wi-Fi access point with a moveable asset in an asset tracking database, where the Wi-Fi access point is disposed on, attached to, or integrated, receiving observation data from a Wi-Fi AP Database including the unique identifying information of the Wi-Fi access point and location information of the Wi-Fi access point, determining a location of the moveable asset based, at least in part, on the observation data of the Wi-Fi access point, and storing the location of the moveable asset in the asset tracking database. There is no communication between the asset tracking database and one or more wireless devices that report an encounter with the Wi-Fi access point, comprising observation data, to the Wi-Fi AP Database.

Apparatus and methods of artificial intelligent based provision of digital content where and when the digital content is needed based upon where a user is located and a purpose for accessing the content as well as credentials of a user seeking to access the digital content. Persistent digital content is linked to location coordinates. More specifically, the present invention links a physical onsite location with digital content to enable a user interface with augmented reality that combines aspects of the physical area with location specific digital content. In addition, access to digital content may be limited to users in defined access areas.

Methods, apparatuses, systems, and non-transitory computer-readable medium are disclosed relating to abnormal transmission identification. One method comprises, at a receiving device, receiving a V2X message from a transmitting device. The method further comprises determining a signal propagation context for the receiving device and obtaining an RSSI value and a distance value for the V2X message. The method further comprises generating an adjusted RSSI value based on (1) the RSSI value and (2) the signal propagation context for the receiving device. The method further comprises obtaining a predetermined RSSI-to-distance relationship model and comparing an adjusted RSSI-to-distance data pair, comprising the adjusted RSSI value and the distance value, to the predetermined RSSI-to-distance relationship model. The method further comprises, in response to determining that the adjusted RSSI-to-distance data pair fails a criterion for conforming to the predetermined RSSI-to-distance relationship model, identifying the V2X message as an abnormal transmission.

The arrangements of the present disclosure are directed to systems, methods, and non-transitory computer-readable media for generating a first map, determining that a distance between the first location and the second location is within a first predetermined range, determining that the first asset is located on or adjacent to the second asset in response to determining that the distance between the first location and the second location is within the first predetermined range, in response to determining from a records database that the first asset is assigned to be moved by the second asset and that the first asset is located on or adjacent to the second asset, verifying that the first asset is being moved by the second asset, and updating a second map and a third map based on the first map, the second map being a Simultaneous Localization and Mapping (SLAM) map, and the third map being a Computer-Aided Design (CAD) drawing.

A tracking system can provide configuration instructions to an electronic device based on user presence. The tracking system can determine a user’s location relative to a geographic boundary surrounding a geographic area associated with the user. Depending on the user’s location, the tracking system may send instructions to configure an electronic device to send a notification or change the operating mode of the electronic device in response to the user’s presence. The electronic device may be a scanning device that is configured to have a higher or lower scanning frequency, depending on the presence or absence of the user relative to the scanning device.

Aspects concern a system and method for determining a state of an electronic device comprising a processor arranged in wireless signal communication with the electronic device to obtain a first wireless signal associated with the electronic device, convert the first wireless signal to a first signal measurement, and compare the first signal measurement with a first threshold; wherein if the first signal measurement is less than the first threshold, the processor is operable to obtain a plurality of successive wireless signals associated with the first wireless signal and corresponding signal measurements over a predetermined period to determine a gradient measure, and if the gradient measure is negative over the predetermined period, the processor determines that the electronic device is in a first state.

An example system includes a first beacon configured to communicate a first wireless signal. A first hub is in communication with the first beacon. The first hub is configured to detect a first signal strength of the first wireless signal. The example system further includes a second hub in communication with the first beacon. The second hub is configured to detect a second signal strength of the first wireless signal. The example system further includes a computing system in communication with the first hub and the second hub. The computing system includes a noise filter and a beacon assignor. The noise filter includes a quadratic estimator configured to output a first estimated distance between the first beacon and the first hub, output a second estimated distance between the first beacon and the second hub, and disregard a third estimated distance between the first beacon and the first hub if the third estimated distance is derived from a ghost signal. The beacon assignor is configured to assign the first beacon to the first hub if the first estimated distance is less than the second estimated distance.
