Personnel identification devices

摘要

An identification device comprising an IR LED contained within a housing which is adapted to be carried externally by a person or object who or which is to be identifiable in dark conditions. In cases where the device is to be used as a personnel identification beacon (PIB) the housing can carry means to enable it to have a "stick-on" capability whereby the housing can be easily attached or detached to/from the external clothing of a wearer. The IR LED can be adapted to flash and this can be in a coded sequence to enable the particular wearer to be identified.
