Patent attributes
Certain embodiments of the invention may be found in an ultra low power dosimeter assembly. The ultra low power dosimeter assembly may include a low power voltage source and a table circuit. The table circuit may be adapted to convert an input voltage to a second voltage level. The second voltage level may correspond to noise dose. The ultra low power dosimeter assembly may also include a switch adapted to trigger a control circuit. The control circuit may provide progressive attenuation of an output signal as the second voltage level increases. In certain embodiments, the control circuit may also be adapted to send one or more warning signals to a user of the ultra low power dosimeter. The one or more warning signals may be sent when the control circuit determines the second voltage level has reached one or more pre-determined threshold voltage levels.
