Assuming e(*) is white Gaussian distributed noise,

this is an excellent application for Kalman filtering

SafetySet™

Use of Boolean algebra along with the Kalman filter to solve the linear quadratic Gaussian control problem in a dynamic recursive predictable model

Real-Time Location Features• Searches:

– Location-Floor, Zone, Property (cleared)– Assets by Owner, Type, Mfg, Model– People by Name, Dept, Type (visitor)– Tag by ID, Motion State, Panic, Battery

• Main Viewer Supports:– Zoom in and out, pan, area– Displays search results– Tracking Mode to follow Tag

• Reporting:– Searches done each day– Searches by Asset Type, People, Tags– Area most frequently searched
