A mobile electronic device includes a wireless communications interface configured to receive, from a remote device, a sequence of remote device proximity indicators. The sequence of remote device proximity indicators indicate positions of the remote device. A mobile proximity detector of the mobile electronic device is configured to monitor a current position and a current velocity of the mobile electronic device; determine, from the sequence of remote device proximity indicators, a current remote device position and current remote device velocity; and determine, using at least the current remote device position and velocity, and the current position and the current velocity of the mobile electronic device, a likelihood of close contact between a user of the mobile electronic device and the remote device. A notification manager of the mobile electronic device is configured to notify the user of the likelihood of close contact.

The present inventive concept includes a duct system and method for using same to map and locate ducts. A preferred embodiment of the duct system includes a duct, a plurality of electronic information modules and an oversheath at least partially covering the plurality of information modules and fixing the information modules to the duct. The plurality of information modules are configured to emit a positional signal to enable location of the information modules and associated duct(s) and/or mapping of the duct system.

An apparatus includes a processor, a transceiver connected to the processor, an integrated circuit connected to the processor, a first proximity sensor configured to provide a first sensor input to the integrated circuit, and a second proximity sensor configured to provide a second sensor input to the integrated circuit. When the integrated circuit determines that the first sensor input represents a first detection event, the processor sets a timer and when the timer expires before the integrated circuit determines that the second sensor input represents a second detection event, the processor sends a message through the transceiver.

Deployable navigation beacons can be deployed from a vehicle, such as an unmanned aerial vehicle (UAV), in an event of a loss of position or orientation of the vehicle. After deployment of the navigation beacons, the vehicle may detect locations of the navigation beacon, which may define a surface that may include surface features. The vehicle may then perform control operations based on the resolved locations. For example, UAV may maneuver to land proximate to the navigation beacons after resolving locations of the navigation beacons as a continuous surface. The navigation beacons may output a visual signal (e.g., a light), a auditory signal (e.g., a sound), and/or a radio signal. In some embodiments, each navigation beacon may include a different or unique signal.

Disclosed is a radio-visual approach for device localization. In particular, a mobile device may receive, via radio signal(s) emitted by transmitter(s) in a vehicle that is substantially proximate to the mobile device, radio data that represents vehicle information associated with the vehicle, and may then determine or obtain a location of the vehicle in accordance with that vehicle information. Also, the mobile device may capture an image of the vehicle and may use that image as basis for determining a relative location indicating where the mobile device is located relative to the vehicle. Based on the location of the vehicle and on the relative location of the mobile device, the mobile device may then determine a location of the mobile device.
