Patent ID: 7566484

Claim:
An article of manufacture for heat absorption, comprising: (a) a flight data recorder that includes electronics that are sensitive to heat; (b) hydroxide having a formula of M x (OH) y , wherein “M” is selected from the group consisting of lithium, sodium, potassium, magnesium, calcium, beryllium, aluminum and ammonium, and wherein “x” and “y” are integers, said hydroxide being provided in an amount sufficient to effect a level of heat absorption so as to protect the electronics within the flight data recorder from damage based upon exposure to a predetermined level of heat exposure; (c) support means for supporting said hydroxide, said hydroxide being supportable in relation to the flight data recorder by said support means; wherein said hydroxide effects said level of heat absorption at least in part based on an irreversible decomposition of said hydroxide; and wherein irreversible decomposition of the hydroxide forms a thermal insulation oxide layer around the flight data recorder.
