The Surface Proximity Module is mounted on a vehicle or piece of machinery and is connected to a central control unit. The Surface Proximity Module interfaces to a central control unit, other modules (dual) or as a stand alone (single) unit which interfaces directly to a vehicle or piece of machinery. 1.1 Theory of Operation The functions of the Surface Proximity Module are:  To transmit a 73kHz field around a vehicle or piece of machinery to act as a protection zone for collision avoidance and for proximity detection for the protection of individuals.  To receive a 916.48MHz RF signal from other vehicles or Personal Alarm Devices (PAD).  To receive a 73 kHz field that might be transmitted by other vehicles.  To generate a 916.48MHz RF signal to alert other vehicles or machinery that a collision possibility exists. The Surface Proximity Module has an internal 73 kHz generator and wire wrapped ferrite radiator that create a field which creates a protection zone around the vehicle or machine. When certain other devices, either vehicle mounted or worn by individuals, are brought too close to the Surface Proximity Module they will detect this 73 kHz field and will analyze its field strength. If the 73 kHz field strength received by the other devices is above a certain threshold, indicating that the distance between the Surface Proximity Module and the device is close enough to indicate a Warning or Danger condition, then they will reply to the Surface Proximity Module with a 916.48MHz transmission. The Surface Proximity Module has its 916.48MHz receiver on when it is transmitting the 73 kHz field and is “listening” to receive any 916.48MHz transmissions from another vehicle, machine or individual equipped with the HazardAvert system that would indicate the individual or other piece of machinery is too close and warrants a warning or danger condition. During the time that the Surface Proximity Module’s 73 kHz generator is not transmitting, the Surface Proximity Module’s 73 kHz receiver is on. This 73 kHz receiver is attempting to detect the field that may be emitted by another vehicle or piece of machinery in close proximity. If during this time the Surface Proximity Module receives a 73 kHz transmission, who’s field strength is above a level determined to represent a possible collision or individual in too close of proximity, the Surface Proximity Module will turn off its 916.48MHz receiver and will transmit its own 916.48MHz signal to alert other vehicles or machinery of its close proximity to them. If the Surface Proximity Module receives indication that a Warning or Danger condition exists, it will turn on that appropriate LED indicators and will communicate this information to the central controller or other modules (duals) and singles.
