Abstract
A method of tracking a human or animal is disclosed. A mobile unit is carried by the human or animal, the mobile unit including at least one inertial sensor and a radio transmitter for transmitting data from the mobile unit to a base station. The output data of the inertial sensor is used to count the number of steps taken by the human or animal, and the position of the human or animal is predicted based on the number of steps taken and step length data for the human or animal.
Claims21
A method of tracking a human or animal comprising:
- providing a mobile unit to be carried by the human or animal, the mobile unit including at least one inertial sensor generating inertial data and a radio transmitter for transmitting the inertial data from the mobile unit to a base station;
- using the inertial data at the base station to count the number of steps taken by the human or animal;
- and
- predicting the position of the human or animal based on the number of steps taken and step length data for the human or animal.
A system for tracking a human or animal comprising:
- a mobile unit to be carried by the human or animal, the mobile unit including at least one inertial sensor generating inertial data and a radio transmitter for transmitting the inertial data from the mobile unit;
- and
- a base station for receiving data from the mobile unit, the base station comprising:
- means for counting, from the inertial data, the number of steps taken by the human or animal;
- and
- means for predicting the position of the human or animal based on the number of steps taken and step length data for the human or animal.
A mobile unit to be carried by a human or animal for tracking the human or animal comprising:
- at least one inertial sensor and a transmitter for transmitting data from the mobile unit to a base station.
A base station for tracking a human or animal comprising:
- a receiver for receiving output data of an inertial sensor from a mobile unit carried by the human or animal;
- means for counting, from the inertial data, the number of steps taken by the human or animal;
- and
- means for predicting the position of the human or animal based on the number of steps taken and step length data for the human or animal.
