In some embodiments, a hash of at least a portion of each computing module's memory data may also be performed.

The problem that a battery will have reduced function (both in ability to deliver energy and in ability to receive energy for storage) as a function of low temperature is addressed by cycling current out of the battery and into a capacitor, and from the capacitor back into the battery, all at sub-hertz frequencies. This warms the battery due to its own internal resistance, thereby warming the battery. The warmth is delivered exactly where it is needed. The currents can be smaller at first (when the battery's current-delivery abilities are limited due to cold) and can be larger as the battery warms up, until the battery is warm enough to deliver most of its capability. Such cycling of current can provide warming that is useful in cold terrestrial environments or in space.
In an energy storage system that includes a battery and an ultracapacitor, the state of charge (SOC) of the capacitor is the subject of a dynamic set-point. This dynamic set-point control is a function of the load regime to which the storage system is exposed, for example a hybrid automobile or electric automobile. The control may be based in part upon real-time fast Fourier transform analysis of load current, permitting real-time adjustment of control coefficients. In this way, it is possible to minimize the occurrence of the capacitor being fully charged at a time when it would be desired to be able to absorb high current, for example from regenerative braking. Likewise it is possible to minimize the occurrence of the capacitor being nearly discharged at a time when it would be desirable to have boost power available. A result is that even a relatively small ultracapacitor (having perhaps one two- hundredth the energy storage capacity of the battery) can permit greatly reducing waste heat dissipated in the battery, and can reduce otherwise unnecessary cycling of current into and out of the battery. This can extend battery life and battery performance.

An ultracapacitor design (300) minimizes the internal pressure of the cell package (320) by using gas getters (350, 352), either alone or in combination with a resealable vent (308) in the package. Reducing pressure extends the life of the ultracapacitor (300). The primary gas types generated within a particular ultracapacitor are measured under multiple possible application conditions. Such conditions may include variables of temperature, application voltage, electrolyte type, length of use, and cycles of use. The primary gas components may be determined and suitable gas getters (350, 352) for different conditions may be formulated. The gas getters (350, 352) may be packed within the ultracapacitor packages (302), formulated as part of a negative electrode, doped into the negative current collector, or layered with the negative current collector.

A transparent vacuum formed vessel 1 is filled with a liquid 3 at room temperature that will become a solid at freezing temperature and a low density float material 4. After freezing, the vessel is turned upside down so that upon thawing, the vivid colored float will move to the top of the vessel showing a thaw. The devise can be reused.
The same concept can be used as a cooking aid by using a transparent sealed tubular 1 assembly inserted in the food with a solid cylinder 3 that will melt at some critical temperature allowing the low density float to rise to the top of the indicator visibly protruding from the food. More than one meltable cylinder, 3 & 8 and float, 4 & 5 may be used as a warning and ready indicator.
Combinations of solid dense particulates and low density materials may also be used for color changing indicators. A permanent magnet attached to a float can be used to trigger an audible alarm, which can be incorporated in various cooking utensils to show cooking temperatures and times.
