Geofencing techniques

1. A controller, comprising:

logic, including hardware logic, configured to:

receive, in the controller, a geofencing definition and input from at least one location information device;

update a location of the controller using one or more location parameters from the at least one location information device and update frequency which is based on at least one of a velocity measure or a proximity to a specific point of interest;

generate notification signal when the location of the controller indicates that the controller has determined an alert condition; and

implement a context-based location updated routine, wherein the context-based location routine is to update the location of the controller using an update frequency which is to vary as a function of a level of a charge level of a battery which is capable of at least partially powering the contoller.

2. The controller of claim 1 , wherein the logic is further configured to combine location information from a plurality of location information devices.

3. The controller of claim 1 , wherein the context-based location routine is to update the location of the controller using an update frequency which is to vary as a function of the one or more location parameters.

11. A computer program product comprising logic instructions stored on a tangible computer readable medium which, when executed by a controller, configure the controller to:

receive, in the controller, a geofencing definition and input from at least one location information device;

update a location of the controller using one or more location parameters from the at least one location information device and update frequency which is based on at least one of a velocity measure or a proximity to a specific point of interest;

generate a notification signal when the location of the controller indicates that the controller has crossed a threshold; and

implement a context-based location update routing, wherein the context-based location routine is to update the location of the controller using an update frequency which is to vary as a function of a level of a charge level of a battery which is capable of at least partially powering the controller.
