1. A mobile signature analysis unit comprising: a sensor module having at least one accelerometer and configured to monitor and capture activity information corresponding to an entity, the activity information including acceleration information and energy impulse information; a processing unit configured to: receive the activity information from the sensor module, detect a signature from the activity information by: identifying at least two directional changes in the acceleration information in each of at least two spatial directions, wherein each of the at least two directional changes are represented by a corresponding inflection point, determining whether a distance between the inflection points within each spatial direction exceeds a predetermined threshold value, and determining whether a value of the energy impulse information exceeds an energy impulse threshold value, and determine an activity type corresponding to the detected signature; a communication module configured to establish communication with a home unit, wherein the home unit is configured to issue a notification reporting the determined activity type corresponding to the detected signature; and an external communication module configured to establish communication with at least one mobile communication device using a corresponding one of a plurality of communication techniques, wherein the at least one mobile communication device is configured to issue the notification reporting the determined activity type corresponding to the detected signature.
