Abstract

A method and device has been developed to enable emergency responders to maintain and communicate their orientation relative to a fire building or other emergency incident area as they work in and around it. The device is a specialized compass enhancement providing a standalone unit that each responder can carry. The device has a multipart structure including: (1) an underlying base is a simple compass that the responder orients to north. (2) A bezel rotatable around the simple compass is preferably square in shape and represents the building or incident area and is labeled with NIMS standardized ABCD designations. (3) An optional rotatable pointer can be independently positioned to indicate a direction to be remembered such as the direction in which the responder entered the incident area. All of the parts can be synchronized among users at any time by radioing simple verbal descriptions of the rotational setting(s).

Claims

1. An emergency responder'"'"'s orientation device for use in an incident area that may be a building, the device comprising:

a north-pointing compass having a center axis and a scale labeled to identify amounts of rotation around the axis; and

a bezel, rotatable about the axis, and labeled to identify radially outward directions toward named portions of the incident area;

wherein

the bezel labels and the scale labels are arranged such that at least one of the bezel labels can be seen to align with a scale label.

2. The orientation device of claim 1 wherein:

the bezel is rectangular in shape to represent an incident area that has four sides, each side being one of the named portions of the incident area; and

at least one of the four bezel sides is labeled with a standardized incident area side name.

3. The orientation device of claim 2 wherein:

the bezel is square in shape; and

the standardized incident area side names are the letters A, B, C and D assigned to bezel sides in clockwise order from A to D, all according to standards of the National Incident Management System (NIMS) of the United States.

4. The orientation device of claim 1 further comprising:

a pointer that is independently rotatable around the axis to indicate a radial direction to be remembered.

5. The orientation device of claim 4 further comprising:

click-stop and/or frictional resistance to movement that is incorporated in the rotational connection of the pointer to the device.

6. The orientation device of claim 1 further comprising:

click-stop and/or frictional resistance to movement that is incorporated in the rotational connection of the bezel to the device.

7. The orientation device of claim 1 further comprising:

tactile elements on the bezel, positioned as tactile labels identifying radially outward directions.

8. The orientation device of claim 1 wherein:

the amount of rotation around the axis is angularly measured clockwise from a label for the northerly radial direction.

9. The orientation device of claim 8 wherein:

the scale has north, east, south, and west labels spaced 90 degrees apart in clockwise order as for compass directions.

10. The orientation device of claim 1 further comprising:

illumination of the compass north-pointing indicator and of the scale labels.

11. The orientation device of claim 10 further comprising:

a switch for turning on electrically operated illumination.

12. The orientation device of claim 10 wherein:

the illumination is provided by luminescent material.

13. The orientation device of claim 1 wherein:

a bezel label is shaped in the form of a radial pointer.

14. The orientation device of claim 1 wherein:

the compass has a body that extends radially outward from the center axis;

the bezel is rotationally mounted on the body, does not extend as far outward as the body, and reveals the north-pointing indicator of the compass;

the scale labels are on the body outside the radial extent of the bezel; and

a label for the northerly direction is positioned such that the north-pointing indicator can be seen to align with it when the body is turned to cause that alignment.

15. The orientation device of claim 1 further comprising:

a hanger ring or a strap with a clasp.

16. The orientation device of claim 1 wherein:

the device is affixed on, or built-in to, a tool or an item of clothing.

17. The orientation device of claim 16 wherein:

the tool is a battery powered lantern; and

the lantern battery is used to power illumination of the device.

18. A method of orientation using the device of claim 1, the method comprising the steps of:

a) setting the device by one of two methods, the first setting method being turning the device until the north-pointing indicator is aligned with a scale label for the northerly direction, then rotating the bezel until it is visually oriented such that the bezel labels point in the direction of named portions of the incident area; and

the second setting method being to receive setting instructions that comprise a bezel label and a scale label that are to be aligned, and then to rotate the bezel to carry out the setting instructions; and

b) orienting oneself relative to the incident area by turning the device which has been set in step (a) until the north-pointing indicator is aligned with a scale label for the northerly direction, then utilizing the bezel labels as radial pointers in the direction of correspondingly named portions of the incident area.
