Multiple hazard field marker and components therefor
First Claim
1. A plurality of field markers for a field marking system, said field markers deployed individually from an airborne deployment vehicle upon a deployment surface, each said field marker comprising a lower portion, an upper portion and a central portion, said lower portion having means to remain erect when deployed associated therewith, said upper portion having means to mark a position on a field where deployed associated therewith, said central portion having means to expand and means to signal associated therewith, a means to activate associated with said means to signal and a means to transmit associated with said means to activate wherein said means to activate activates multiple sensors contained in at least one housing in at least one of said portions upon receiving a command from a remote transceiver.

Abstract
A multiple hazard marker system consists of at least one multiple hazard marker, a deployment vehicle, a deployment surface and a deployment device for deploying the multiple hazard marker. The multiple hazard marker comprises a ground engaging portion, an upper portion and a central portion. The multiple hazard marker will remain erect when deployed and includes a visible marker for marking a position upon a field where deployed. The multiple hazard marker further has collapsible elements that expand upon deployment, a signaling device, a receiver for activating the signaling device and transmitter associated with the signaling device.
