Classification: CPC G | IPC G

Claim 22:
23. A system for measuring a radiant exposure of electromagnetic radiation, comprising:
an accumulation detection module (ADM) comprising a detector and configured to continuously monitor an electromagnetic radiation received by the detector; and
an adaptive circuit configured to periodically interrogate the ADM; adjust a frequency of interrogation of the ADM based on an intensity of the electromagnetic radiation received by the detector; and autonomously transmit information related to an amount of the electromagnetic radiation received by the detector to a remote device,
wherein the adaptive circuit is configured to increase the frequency of interrogation based on an increase in the intensity of the electromagnetic radiation, or decrease the frequency of interrogation based on a decrease in the intensity of the electromagnetic radiation; and
wherein the adaptive circuit is configured to switch the system between:
a sleep mode, wherein when the system is in the sleep mode, the system operates at a first average current consumption; and
a wake mode, wherein when the system is in the wake mode, the system operates at a second average current consumption, wherein the second average current consumption is greater than the first average current consumption.
