A system for allowing a potential buyer of second-hand of a CE device to look up an identifier of the device in a revocation list, in order to determine if the CE device has been partially or full disabled as a result of revocation. In the various embodiments, the generator may include a chamber configured to endothermically decompose a material positioned within the chamber to generate hydrogen gas. The split-beam probe head receives the low-coherence light and splits the incoming low-coherence light into a primary beam and walk-off beam. The polymer binder may be absent or optional.
