  2. Geofence - Wikipedia

    en.wikipedia.org/wiki/Geofence

    The use of a geofence is called geofencing, and one example of use involves a location-aware device of a location-based service (LBS) user entering or exiting a geofence. Geofencing approach is based on the observation that users move from one place to another and then stay at that place for a while.

  3. Geopositioning - Wikipedia

    en.wikipedia.org/wiki/Geopositioning

    Geofencing involves creating a virtual geographic boundary (a geofence), enabling software to trigger a response when a device enters or leaves a particular area. [3] Geopositioning is a pre-requisite for geofencing.

  4. Location-based firearm - Wikipedia

    en.wikipedia.org/wiki/Location-based_firearm

    A location-based firearm is a gun that uses electronic technologies such as geofencing to restrict its firing to authorized locations, thereby allowing its use for protecting life and property in those locations while preventing its use in other locations for crimes such as robberies, drive-by shootings, assassinations, and massacres.

    The Earth-centered, Earth-fixed coordinate system (acronym ECEF), also known as the geocentric coordinate system, is a cartesian spatial reference system that represents locations in the vicinity of the Earth (including its surface, interior, atmosphere, and surrounding outer space) as X, Y, and Z measurements from its center of mass.

  6. Geotagging - Wikipedia

    en.wikipedia.org/wiki/Geotagging

    Real-time geotagging relays automatically geotagged media such as photos or video to be published and shared immediately. For better integration and readability of geotags into blog texts, the meetag syntax has been proposed, which transforms any word, sentence, or precise geolocalization coordinates prefixed with an underscore into a 'meetag'.

  7. Geo-blocking - Wikipedia

    en.wikipedia.org/wiki/Geo-blocking

    Geo-blocking can be circumvented.When IP address-based geo-blocking is employed, virtual private network (VPN) and anonymizer services can be used to evade geo-blocks. A user can, for example, access a website using a U.S. IP address in order to access content or services that are not available from outside the country.

  9. Wire obstacle - Wikipedia

    en.wikipedia.org/wiki/Wire_obstacle

    The effectiveness of any wire obstacle is greatly increased by planting anti-tank and blast antipersonnel mines in and around it. Additionally, connecting bounding anti-personnel mines (e.g. the PROM-1) to the obstacle with tripwires has the effect of booby-trapping the obstacle itself, hindering attempts to clear it.
