Large area position/proximity correction device with alarms using (D)GPS technology

A movable boundary detection system comprising:

• a receiver configured to determine a position of the device;
• a memory module configured to store:
• coordinates that define a plurality of different zones;
• and
• a definition in association with each zone for an action to be implemented when the position of the device is one of near or within the zone;
• a processor module configured to:
• determine whether the position is one of near, approaching, and within one of the zones;
• and
• implement the action associated with a zone in response to determining that the position is one of near, approaching, or within the zone.

A movable point detection device comprising:

• a receiver configured to determine a position of the movable point detection device and to determine a position of a movable electronic device;
• and
• a processor module configured to:
• determine that the position of the movable point detection device is a predetermined distance from the position of the movable electronic device;
• and
• implement an action in response to determining that the position of the movable point detection device is the predetermined distance from the position of the movable electronic device.

A boundary detection system comprising:

• (a) a boundary detection device comprising:
• (i) a positioning signal receiver operable to receive at least one signal indicating position coordinates of a moveable device;
• and
• (ii) a transmitter configured to communicate the position coordinates of the moveable device;
• and
• (b) at least one of a base station and a mobile device comprising:
• (i) a receiver configured to receive the position coordinates of the moveable device communicated from the boundary detection device;
• (ii) a memory module operable to store position coordinates for defining a boundary;
• and
• (iii) a processor module configured to compare the indicated position coordinates of the moveable device to the position coordinates, configured to determine event triggering based on the comparison of the indicated position coordinates to the position coordinates, and configured to communicate information indicating the event triggering via a communications system based on the event triggering determination.

A boundary detection system comprising:

• (a) a boundary detection device comprising:
• (i) a positioning signal receiver operable to receive at least one signal indicating first position coordinates of a moveable device;
• and
• (ii) a transmitter configured to communicate the first position coordinates of the moveable device;
• and
• (c) one of at least one base station and a mobile device comprising:
• (i) a receiver configured to receive the first position coordinates of the moveable device communicated from the boundary detection device and to receive second position coordinates of the moveable device communicated from at least one cellular base station;
• and
• (ii) a processor module configured to determine a position of the moveable device based on the first position coordinates and the second position coordinates.

A boundary detection system comprising:

• (a) a first moveable device comprising:
• (i) a positioning signal receiver operable to receive at least one signal indicating first position coordinates of the first moveable device;
• and
• (ii) a transmitter configured to communicate the first position coordinates;
• and
• (b) a second moveable device comprising:
• (i) a receiver configured to receive the first position coordinates of the first moveable device and to receive second position coordinates of the first moveable device communicated from a wireless communications system;
• and
• (ii) a processor module configured to determine a position of the first moveable device based on the first position coordinates and the second position coordinates.
