Multi-function tracking device with robust asset tracking system
First Claim
1. A tracking system for tracking at least one mobile multi-function device in a defined area, comprising:
- at least one mobile multi-function device adapted to move in said defined area, said multi-function device including a transmitter/receiver and DRM device for determining the position of said multi-function device, said transmitter/receiver being adapted to transmit and receive a signal including data from said DRM device representative of said determined position;
a plurality of multi-function devices spaced in said defined area to present an array of multi-function devices, each of said multi-function devices having a transmitter/receiver and DRM device, said plurality of multi-function devices being adapted to independently determine both the current position of said device and the accuracy of its position and transmit said position and accuracy to other multi-function devices in the system using a mesh communication network in which all the devices may communicate; and
a signal processor positioned to receive transmitter signals from said transmitter/receiver and calculate the position of said mobile multi-function device.

Abstract
A tracking system for tracking at least one mobile multi-function device in a defined area, including at least one mobile multi-function device adapted to move in the defined area. The multi-function devices including a transmitter and a device for determining the position of the device to transmit a signal including the determined position. A plurality of other multi-function devices are placed in and around the defined area to present an array of devices adapted to independently determine both the current position of the device and the accuracy of the position and communicate that to the other devices in the system using a mesh communication network. A signal processor receives the signals from the transmitters and calculate the position of the mobile multi-function device.

11. A tracking system for tracking at least one mobile multi-function device in a defined area, comprising:
-
at least one mobile multi-function device adapted to move in said defined area, said multi-function device including a transmitter/receiver means for transmitting signals and DRM device means for determining the position of said multi-function device, said transmitter/receiver means being adapted to transmit a signal including data from said DRM device means representative of said determined position;
a plurality of multi-function device means for tracking said mobile multi-function device and having transmitter/receiver means for transmitting data and DRM means for determining the position of said multi-function device means and being spaced in said defined area to present an array of multi-function device means, each of said multi-function device means adapted to independently determine both the current position of said device and the accuracy of its position and transmit said position and accuracy to other multi-function device means in the system using a mesh communication network in which all the device means may communicate; and
signal processor means for receiving transmitter signals from said transmitter/receiver means and calculate the position of said mobile multi-function device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
