Black box with volatile memory caching

A method comprising, by a computing device:

• receiving an indication from a collision-detector module that a collision event of a vehicle has occurred;
• initiating a transfer of energy stored in an energy-storage module to the refrigeration module in response to receiving the indication from the collision-detector module that the collision event has occurred;
• and
• transmitting a signal to the refrigeration module initiating lowering a temperature of a volatile memory module in response to receiving the indication from the collision-detector module that the collision event has occurred, wherein the refrigeration module is configured to lower the temperature of the volatile memory module in response to receiving energy from the energy-storage module.

One or more computer-readable non-transitory storage media embodying software that is operable when executed to cause one or more processors to perform operations comprising:

• receive an indication from a collision-detector module that a collision event of a vehicle has occurred;
• initiate a transfer of energy stored in an energy-storage module to the refrigeration module in response to receiving the indication from the collision-detector module that the collision event has occurred;
• and
• transmit a signal to the refrigeration module initiating lowering a temperature of a volatile memory module in response to receiving the indication from the collision-detector module that the collision event has occurred, wherein the refrigeration module is configured to lower the temperature of the volatile memory module in response to receiving energy from the energy-storage module.
