In an approach, a processor identifies that a vehicle has been exposed to a first user, the first user associated with an infectious disease. A processor monitors, via a wireless ad hoc network, presence of a mobile device at a location of the vehicle. A processor identifies the presence of the mobile device at the location of the vehicle. A processor sends a notification to the mobile device, the notification specifying that the vehicle has been exposed to the infectious disease.

A real-time application-based cellular system with real-time GPS positioning to notify civilian drivers of the proximity of emergency services vehicles in sufficient time to allow appropriate response. Civilian users receive alerts and information on their personal computing devices, including, but not limited to, tablets and smart phones. No addition or special hardware is required. Only drivers in a moving vehicle with a certain proximity are directly and selectively notified. The system also is able to send other additional customized warning signals to citizens in threatening situations in a non-vehicular context.

A robot system includes a track that extends along an axis between a first location and a second location. The track includes a pair of rails and a power transmitter and a radiating cable each extending along the track. A carriage is configured to convey a robot arm along the track. The carriage includes a plurality of wheels configured to roll along the pair of rails, a motor configured to drive at least one of the wheels along one of the rails, a power collector configured to translate along the power transmitter while maintaining contact with the power transmitter so as to conduct electrical power from the power transmitter to the motor, and a transceiver configured to receive and send electronic information from and to the radiating cable.

Techniques for establishing communication channels between user devices experiencing network connectivity issues and remote communication systems are described herein. The techniques include the use of a secondary device to act as a proxy, or a “middle man,” to facilitate the communications with the user device. A user device may detect lack of network connectivity, and begin broadcasting advertisement messages that indicate the lack of connectivity. A secondary device may detect the advertisement message, and send a discovery message to a connectivity system indicating that it detected the advertisement message. The connectivity system can provide this information to a remote communication system, and the remote communication system can establish a connection with the secondary device and instruct the secondary device to establish a connection with the user device. The remote communication system then has a communication channel with the user device, using the secondary device, to troubleshoot the user device.

A computer-implemented method for establishing and controlling a mobile perimeter and for determining a geographic location of an RF emitting source at or within the mobile perimeter includes receiving from RF sensors in a network, processed RF emissions from the source collected at RF sensors. The RF emissions follow a wireless protocol and include frames encoding RF emitting source identification information. The method further includes extracting RF emitting source identification information from the frames, processing the source identification information to identify the RF emitting source, and classifying the RF emitting source by one or more of UAS type, UAS capabilities, and UAS model. The method also includes receiving from the RF sensors, a geographic location of each RF sensor and a time of arrival (TOA) of the RF emissions at the RF sensor; and executing a multilateration process to estimate a geographic location of the RF emitting source.

In some examples, a method of vector-raster data fusion includes receiving vector data for a geographical location, and statistically analyzing the vector data to obtain vector statistics. In some examples the method further includes rasterizing the vector statistics, and storing at least one of the vector data and the rasterized vector statistics together in a key-value store together with previously stored raster data for the geographical location. In some examples, the vector data further includes metadata, and the method further includes storing the metadata in at least one of the key-value store or a separate vector database.
