A method for heating an energy storage device having a core with an electrolyte, the method including: providing the energy storage device having inputs and characteristics of a capacitance across the electrolyte and the core and internal surface capacitance between the inputs which can store electric field energy between internal electrodes of the energy storage device that are coupled to the inputs; switching between a positive input voltage and a negative input voltage provided to one of the inputs at a frequency sufficient to effectively short the internal surface capacitance of the energy storage device to generate heat and raise a temperature of the electrolyte; and discontinuing the switching when the temperature of the electrolyte is above a predetermined temperature that is considered sufficient to increase a charging efficiency of the energy storage device.

Methods for heating and charging energy storage devices at very low temperatures

A piezoelectric generator for generating power upon an acceleration and upon a deceleration of a body. The piezoelectric generator including: first and second masses; first and second springs, the first spring being connected to the body at one end and to the first mass at an other end, the second spring being connected to the body at one end and to the second spring at an other end; and a piezoelectric material connected to the first and second masses such that the piezoelectric material generates power when the body is accelerated or decelerated.

Self-powered piezoelectric-based programmable electronic impulse switches

A device responsive to an acceleration pulse event, the device including: a piezoelectric device configured to generate a voltage over a duration responsive to one or more acceleration pulse events; an electrical storage device configured to receive a portion of the generated voltage to accumulate a charge; an energy dissipating device coupled to the electrical storage device and configured to dissipate the accumulated charge following the one or more acceleration pulse events and not to substantially dissipate the accumulated charge during the one or more acceleration pulse events; and a voltage limiting device coupled to the electrical storage device and configured to limit the portion of the generated voltage applied to the electrical storage device to a predetermined limit.
