1. An electronic circuit for monitoring radiation, said electronic circuit comprising:
- a radiation detector that detects an intensity of at least one type of radiation;
a radiation accumulator that receives and accumulates the detected intensity from said radiation detector;
a comparator that determines whether the accumulated intensity exceeds at least one threshold level; and
an output device that is configured for indicating whether the accumulated intensity exceeds the at least one threshold level.

Abstract
An electronic circuit having radiation monitoring capability is disclosed. Radiation, such as ultraviolet (UV) radiation, infrared (IR) radiation or light, can be measured by the electronic circuit. The measured radiation can then be used in providing radiation-related information to a user of the electronic circuit. In one implementation, the electronic circuit is provided within eyewear so that the user of the eyewear is able to easily monitor their exposure to radiation.

12. An electronic circuit for monitoring radiation, said electronic circuit comprises:
-
a radiation detector that detects an intensity of a type of radiation;
a radiation-to-frequency converter that receives the detected intensity and converts the detected intensity to a frequency signal, the frequency signal having a frequency that is dependent on the detected intensity;
an output manager operatively connected to said radiation-to-frequency converter, said output manager being configured to determine whether to output an output indication based on the frequency signal; and
an output device that is configured for outputting the output indication. - View Dependent Claims (13, 14, 15, 16)

17. An electronic circuit for monitoring radiation, said electronic circuit comprises:
-
a radiation detector that detects an intensity of a type of radiation;
a radiation-to-pulse-width converter that receives the detected intensity from said radiation detector and converts the detected intensity to a radiation signal, the radiation signal having a pulse-width that is dependent on the detected intensity;
an output manager operatively connected to said radiation-to-pulse-width converter, said output manager being configured to determine whether to output an output indication based on the pulse-width of the radiation signal; and
an output device that is configured for outputting the output indication. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
