Abstract:
1. A system for electronically recording data about an energy producing event, comprising an event sensing and recording node, wherein said event sensing and recording node includes an energy converting device, a first electronic memory device, and a reading circuit, wherein said energy converting device provides a first voltage, wherein said first voltage varies over a continuous range of values, wherein said energy converting device is connected to record a second voltage in said first electronic memory device when an energy producing event occurs, wherein all energy for recording said second voltage is derived from energy provided by said energy converting device, wherein said reading circuit is connected to said first electronic memory device, wherein said reading circuit is powered from a source of energy other than said energy converting device, wherein when said reading circuit is powered, data having discrete voltage values is provided in said reading circuit determined by said recorded second voltage in said first electronic memory device.
