A sensor node system for mapping hydraulic fractures may include a localization system that identifies location information of the sensor node device with respect to an area of interest in a rock formation. The location information may include various magnetization parameters indicative of various signal strengths surrounding the sensor node device. The sensor node device may include a transceiver that exchanges signals with a base station and at least one other sensor node device. The transceiver establishes a communication link between the base station and the sensor node device. The transceiver may monitor at least one other communication link between the at least one other sensor node device and the base station. The sensor node device may include a processor that identifies distance information based on the location information and a predetermined number of signals associated to the various signal strengths surrounding the sensor node device.

Aspects of the subject disclosure may include, for example, identifying a first position of a first user, identifying a first context associated with the first user, determining, based on the first position and the first context, at least a first action that is recommended to be taken, and providing at least one output that provides an indication of the at least a first action. Other embodiments are disclosed.

Systems and methods for determining precise pick-up locations for passengers who have requested autonomous vehicle rides. In particular, systems and methods are provided for using wireless signals to determine user location. In some examples, wireless ranging technology, such as Ultra Wide Band (UWB), is used to determine the user location. Wireless transceivers are used to determine a mobile device's range, and range information from multiple transceivers is used to determine the mobile's device's position. In some examples, triangulation is used to determine user location, such as triangulation between one or more wireless transceivers and the mobile device. In various examples, wireless transceivers are installed on autonomous vehicles, and in some examples, wireless transceivers are installed in various static locations (e.g., on buildings, lamp posts, or other structures.

Call spoofing can be mitigated by providing geolocation information to the called device. For example, when a call rings, a geolocator can be invoked and the incoming call display screen can show a carrier logo and/or a geolocator globe illustrating the location of the call originator. The geolocation session initiation protocol data can be confirmed by a network device and compared against carrier specific data of the calling device to authenticate voice calls for called devices. In one embodiment location data of the calling device can purposely be shared in order to facilitate the mitigation of call spoofing.

A safety system for localizing a person or object has a control and evaluation unit, at least one radio location system, and at least one spatially resolving sensor for the position determination of the person or object. The radio location system has arranged radio stations, wherein at least one radio transponder is arranged at the person or object. Position data and classification data of the person or object can be determined by means of the radio location system. The position data and the classification data can be transmitted from the radio station to the control and evaluation unit and position data and contour data of the person or object can be determined by means of the spatially resolving sensor. The control and evaluation unit is configured to compare the position data of the radio location system and the position data of the spatially resolving sensor.

In one example, a server obtains an indication that a first mobile device is in a predetermined proximity to a non-mobile device. In response, the server permits the first mobile device to pair with the non-mobile device. The server generates whitelisted information associated with the first mobile device by adding information associated with the first mobile device to a whitelist that controls mobile device pairing for the non-mobile device. The server also obtains an indication that a given mobile device has obtained one or more keep-alive messages from the non-mobile device. Based on the whitelisted information, the server determines whether to permit the given mobile device to pair or remain paired with the non-mobile device. In response to determining to permit the given mobile device to pair or remain paired with the non-mobile device, the server permits the given mobile device to pair or remain paired with the non-mobile device.

A matching and communication system has a first mobile device associated with a first user, and a second mobile device associated with a second user, an Internet connected server having a processor executing coded instructions, and coupled to a data repository, a first profile for the first user, comprising a photograph of the first user and a plurality of first hashtags in the first profile, the first profile stored in the data repository; and a second profile for the second user, comprising a photograph of the second user and a plurality of second hashtags in the second profile, the second profile stored in the data repository. The server determines that the devices are proximate a profile post is displayed for the second user in a display for the first user.

A social distancing system that addresses maintaining a minimum social distance of 6 ft during a pandemic by using social distancing devices that determine the distance between devices and generate alarms when the minimum social distance is violated.

An information processing system includes: an image display apparatus provided in a space and configured to display an image; a sensor apparatus carried by a user who is present in the space and configured to output a signal for detecting position information of the user in the space; and an information processing apparatus. The information processing apparatus includes circuitry configured to store a plurality of pieces of position information of a plurality of users including the user, who are in present in the space, in association with the plurality of users, the plurality of users being detected based on signals output from a plurality of sensor apparatuses including the sensor apparatus, and control environment effect production that supports communication between the plurality of users by the image displayed by the image display apparatus, based on each of the plurality of pieces of position information of the plurality of users.

A vehicle control apparatus includes a battery remaining-amount recognizing unit recognizing a remaining amount of a battery and a distance measurement control unit measuring a vehicle-terminal distance by switching, based on the remaining amount of the battery recognized by the battery remaining-amount recognizing unit, between a first distance measurement mode repeatedly measuring the vehicle-terminal distance by a distance measuring unit without depending on reception of measurement instruction information transmitted from a mobile terminal and a second distance measurement mode measuring the vehicle-terminal distance by the distance measuring unit in response to reception of the measurement instruction information transmitted from the mobile terminal when communication is established between the vehicle communication control unit and the mobile terminal.
