Emergency workers and other personnel are often endangered by losing contact with other personnel, for example, firefighters working in hostile conditions. Methods and devices for improving the survivability and reducing the potential for injury or death of emergency personnel and others are provided. The methods and devices monitor the distance of members of a group to, among other things, minimize or prevent personnel from being separated from the group. Devices worn by members of a group monitor the distance between members by monitoring the characteristics of wireless communication, for example, signal strength, between members. If the distance between members exceeds or is less than a predetermined distance, an alarm is sounded to alert members to the potential for contact between members or loss of a member of the group. Though aspects of the invention may be used by emergency workers, such as firefighters and policemen, other aspects of the invention may be used to monitor objects or children, among others.

An improved thermal imaging camera system is adapted to be releasably mounted to a protective helmet typically worn by a firefighter or other emergency personnel at an incident site. The present system comprises a thermal imaging camera assembly having a single eyepiece display flexibly coupled thereto, a protective housing for the camera assembly and a specially adapted mounting bracket assembly for releasably stationing the camera assembly and its protective housing in a central position on the helmet. The camera assembly further includes and integrates a miniaturized infrared camera unit with associated battery power supply and control electronics for high resolution image production. The single eyepiece display is flexibly coupled to the camera assembly and its housing by means of an articulated arm that accommodates positioning of the display in front of either the left or right eye of the user-wearer with or without an air mask or other protective interface being worn over the face of the user-wearer. The mounting bracket assembly includes a T-shaped base bracket having a rectangular head adapted to be fixed in a level position on the front of the helmet and a C-shaped upper bracket attached to the bottom of the housing and formed to slidingly engage the head of the base bracket thereby holding the camera system in proper position on the helmet. Spring-loaded detents on opposite sides of the head of the base bracket serve to lock the bracket assembly together by engaging the sides of the upper bracket and further allow manual disengagement therefrom so that the camera system may be quickly removed from the helmet and rapidly deployed on another similarly equipped helmet.

From ancient history until now, man has constructed high-rise buildings of various kinds. They include monuments, castles, churches, office buildings, hotels, hospitals and residences. No matter how sophisticated construction techniques and technology have become, there is no system to transport people and equipment to or from selected locations between the ground level and roof of a high-rise; quickly, economically, consistently and safely outside the structure. Reed's High-Rise Emergency Rescue Egress System is such a system. This system solves the myriad problems which have existed for centuries relating to a need for external, vertical high-rise emergency evacuation and does so with substantial cost-efficiencies. Reed's High-Rise Emergency Rescue Egress System is comprised of varied electronic and mechanical components operating in unison. The three major pieces to the high-rise system are; a vehicle, a gondola and a roof-mount cantilever: The vehicle is a self-powered ground vehicle containing a gondola, stabilizing steel cables, drums, television screens, video cameras, communications, and remote control equipment. Once linked to a cantilever it provides power for lifting the gondola, equipment and personnel to monitor all activities below, beside or above the fire area. The self-powered cantilever is, remotely or manually, positioned on the roof of a high-rise building to a desired area of operation. The cantilever extends its connection arm over the edge of a high-rise building and lower cables to the ground rescue vehicle to make necessary connections with the gondola for traveling up and down the walls of a high-rise building. The cantilever roof-mount system is portable and contains steel cables, electric / hydraulic wenches, radio receivers, transmitters and video communication. The gondola, an enclosed cabin, is positioned on the rear, body portion, of the high-rise rescue vehicle. Once the gondola is linked to the vehicle and cantilever arm it becomes an exterior enclosed transporter in a matter of minutes. Reed's High-Rise Emergency Rescue Egress gondola will carry up to eight fully equipped firemen and can scale the wall of a burning building in minutes. The gondola carries firefighters and equipment below, beside or above the fire, while at the same time providing trapped building occupants a safe means of escape. A modified version of the gondola is used for high-rise building construction and maintenance.
