Abstract
Apparatuses, methods, apparatuses and systems for tracking motion are disclosed. One method includes identifying a group of sensors that includes a plurality of neighboring sensors sensing motion greater than a threshold during a time interval, and tracking motion, comprising linking the group to at least one past group of at least one past time interval.
Claims16
A method of tracking motion, comprising:
- sensing, by a plurality of sensors of a plurality of fixtures, motion;
- identifying, by a controller that receives the sense information from the plurality of sensors, a group of sensors that includes a plurality of neighboring sensors sensing motion greater than a motion threshold during a time interval;
- tracking motion, by the controller, comprising:
- linking the group to at least one past group of at least one past time interval, wherein the at least one past group includes a group of sensors that sensed motion during the at least one past time interval;
- confirming, by the controller, that the group originated from the at least one past group of the at least one past time interval, comprising confirming that the group is located within a common area as the at least one past group, and confirming that the group includes at least one neighboring sensors of the at least one past group;
- and
- tracking motion through a structure based on the linking of the group to the at least one past group;
- and
- refining, by the controller, the group of sensors, comprising:
- checking locations of each of the plurality of sensors of the group;
- comparing the locations with locations of known obstructions;
- and
- eliminating at least one sensor of the group that cannot be included within the group due to the location of the obstruction.

- and
- evaluating, by the controller, all child groups of a prior group to determine which of the child groups provides a most likely trail of the prior group.
