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, anddetermining whether a value of the energy impulse information exceeds an energy impulse threshold value, anddetermine 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.

Abstract
A signature analysis system can include a mobile signature analysis unit and a home unit. The mobile signature analysis unit can include a sensor module to monitor and capture an entity'"'"'s activity information and a processing unit to analyze the activity information to detect a signature and determine an event corresponding to the signature. If the mobile signature analysis unit determines that a user has experienced a fall, for example, a notification can be sent to the user'"'"'s caregiver by one or both of the mobile signature analysis unit and the home unit.

10. A machine-controlled method comprising:
-
a mobile signature analysis unit monitoring activity information corresponding to an entity, the activity information comprising acceleration information and energy impulse information; a sensor module of the mobile signature analysis unit capturing the activity information and sending the activity information to a processing unit of the mobile signature analysis unit; the processing unit of the mobile signature analysis unit detecting a signature from the activity information by identifying within the acceleration information a plurality of direction changes in each of at least two spatial directions and further by determining whether a value of the energy impulse information exceeds an energy impulse threshold; the processing unit of the mobile signature analysis unit determining an activity event corresponding to the detected signature by comparing the detected signature to at least one signature template; and responsive to determining the activity event corresponding to the detected signature, the mobile signature analysis unit establishing communication with at least one caregiver and issuing a notification to the at least one caregiver, the notification reporting the determined activity. - View Dependent Claims (11, 12, 13, 14)
