A locating badge comprising a housing containing an opaque medium and an IR transmitting device. At least a portion of the housing is transparent to visible light and a portion to IR, and the housing preferably comprises two releasably mechanically engageable housing members. The opaque medium, viewable through the transparent portion of the housing, may be an elastomeric membrane, which also provides water resistance by sealing the seam between housing members. Additional functionality may be provided by inserting identification materials within the housing (also viewable through the transparent portion of the housing) or by providing an opening in the housing allowing access to a membrane button, wherein the elastomeric membrane functions as the cover for the button and as a sealing gasket around the opening in the housing. The badges described herein can easily be used in a color-coded system, by changing the opaque medium inside the badge. |
