the MX3 Proximity Detection system, It satisfy the market needs of mine have to meet the MSHA proximity detection role. The intent of IntelliZon Proximity is to provide a practical, mine-duty system that will automatically warn personnel when they are entering a potentially hazardous area around a machine. The system must be able disable some or all machine functions if a particular zone is breached. A proximity detection system detects when a person enters a dangerous area around a given machine and changes machine operation accordingly. The machine can be configured to stop or slow all or some operations. The MX3 Matrix Proximity Detection System will be a packaged product that will vastly improve our current proximity detection system by enabling it to function at greater distances, function on any piece of mobile equipment, as well as decrease response time and increase accuracy.

The CAN Bus interface of the proximity detection system must conform to ISO 11898 at the Physical Layer, utilizing a full CAN implementation of the CAN 2.0B protocol, transmitting at 125 k baud, using 11 bit identifiers. Cabling of the CAN Bus between the Proximity Detection System and FaceBoss will be Belden 3072F cable (Joy P/N 100172283), or equivalent. There will be no provision internal to the Proximity Detection system for the addition of the 120 ohm terminating resistor required for CAN communications. This resistor will be added external to the system. The proximity detection system must be capable of providing a wireless access point. This access point may utilize an external antenna connection The proximity detection system must be capable of providing a 10/100BaseTX Ethernet connection (4-wire Ethernet) via a secondary interface connection. The connection speed setting must be software configurable between 10Mbps and 100Mbps. Environmental Requirement Operating Temperature Range: -10oC to +55oC Power Supply Power Supply Input Voltage: 72V and 24V Preliminary 11 Note: If Power source uses AC line power: A line power filter is required to use for AC line emission noise suppressions. USB Wireless Wired 3299 Tower Drive Newburgh, IN 47630 812.490.1525 www.MatrixTeam.com System Operation System The drivers emit a magnetic field around the machine they are mounted on. The locators respond to this magnetic field and communicate via radio frequency with the controller. The controller performs an algorithm to determine where, in relation to the machine, the locators are. When a locator breaches one of the configurable zones created around the machine, the proper configurable action is performed. Zoning Fully configurable zones based on inputs from Machine (e.g. High, Medium, Low, Cutter On, Forward, Reverse) and outputs for the Proximity Detection System. Multiple zones can be active simultaneously. Each zone can have multiple personnel types applied to it. Zone Red Zone Minimum Zone Requirements Continuous Miner Operator zone (applies only to the PWD associated as this machines operator; Only apply cutter zone to operator-associated PWD) Non-operator zone (encompassing all PWDs that are not associated to this specific CM as an operator) Shuttle Car Forward Zone Reverse Zone Yellow Zone Non type-specific zone (this warning zone by default will apply to all PWDs, both operator and non-operator) Forward Zone Reverse Zone Green Zone Operator zone (this operator zone allows the associated PWD to operate the machine not shutdown the machine) Operator zone (this operator zone allows the associated PWD to operate the machine not shutdown the machine) Personal Association Preliminary 12 3299 Tower Drive Newburgh, IN 47630 812.490.1525 www.MatrixTeam.com The controller will be able to distinguish between a machine operator and all other personnel. Multi-Machine Operation Shuttle car has to have the ability to approach the Miner without shutting either machine down while maintaining safe distances for personnel. A button press by the operator will start the process of modifying or reducing the zones. Port Test: There shall be a port test on the machine. The boot sequence on the controller should run the port test automatically for a configurable number of seconds. GUI communication will be provided in the form of a laptop operating on Linux or Windows. There will be wired and wireless communications available on the controller. PWDs will have the ability to be updated over the air. Logging will be provided in the system in the binary and text forms. The CAN bus is used to communicate with the equipment the system is installed on. The CAN bus supports multiple CAN protocols as needed for the installation.

1. This device may not cause harmful interference, and 2. This device must accept any interference received, including interference that may cause undesired operation. Warning: Changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:

* Reorient or relocate the receiving antenna.

* Increase the separation between the equipment and receiver.

* Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

* Consult the dealer or an experienced radio/TV technician for help. Canadian Compliance Statements This Device complies with Industry Canada License-exempt RSS standard(s). Operation is subject to the following two conditions: 1. This device may not cause harmful interference, and 2. This device must accept any interference, including interference that may cause undesired operation of the device. Note: Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Ce dispositif est conforme aux normes CNR exemptes de licence d'Industrie Canada. Le fonctionnement de ce dispositif est autoris sous rserve des deux conditions suivantes: 1. Ce dispositif ne doit pas produire de brouillage et 2. L'utilisateur du dispositif doit tre prt accepter tout brouillage radiolectrique reu mme si ce brouillage est susceptible de compromettre le fonctionnement du dispositif. Remarque: Conformment la rglementation d'Industrie Canada, le prsent metteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou infrieur) approuv pour l'metteur par Industrie Canada. Dans le but de rduire les risques de brouillage radiolectrique l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonne quivalente (p.i.r.e.) ne dpasse pas l'intensit ncessaire l'tablissement d'une communication satisfaisante.
