1. A floor monitoring tile comprising:
- a contact layer having an upper surface and a lower surface, the lower surface having a plurality of conductive contacts;
a sensor layer having a plurality of first conductors and a plurality of second conductors, each first conductor having a plurality of first contact points and each second conductor having a plurality of second contact points, for each contact a respective first contact point of said first plurality of contact points and a respective second contact point of said second plurality of contact points forming a set being aligned with the contact;
wherein for each contact, when no force is applied to the contact, the respective first contact point and the respective second contact point remain electrically isolated and when force is applied to the contact, the respective first contact point and the respective second contact point electrically connect through the contact.

Abstract
The invention discloses a system including floor tiles for monitoring the movements of individuals across a floor surface. The system is comprised of a plurality of floor tiles electrically and mechanically interconnected. The floor tiles are monitored to determine where, when and how weight is applied to the floor tiles. The system may also comprise an identification system comprising individual transmitters and a receiver. The receiver is tied into the tile monitoring system to allow the identification of an individual on the floor surface.

14. A system for monitoring the movements of at least one individual across a floor surface comprising:
-
a plurality of floor tiles;
the floor tiles each having an upper surface, a contact layer, a sensor layer and a detector;
the contact layer having a plurality of conductive contacts; and
the sensor layer comprising a plurality of pairs of contact points which are electrically connected by the conductive contacts of the contact layer when force is applied normal to the contact points;
wherein the detector calculates an area of the floor tile over which the force is applied as a function of time. - View Dependent Claims (15, 16, 17, 18, 19, 20)
