Patent ID: 8277734

Claim:
A system comprising: an ultraviolet radiation source configured to generate ultraviolet radiation shone within an area; an ultraviolet radiation detector configured to sense ultraviolet radiation within the area; and a computer system including at least one computing device, wherein the computer system is configured to: monitor the ultraviolet radiation sensed by the ultraviolet radiation detector over a period of time; determine a set of biological activity dynamics for the area based on the sensed ultraviolet radiation and the period of time, wherein the set of biological activity dynamics includes: a current growth phase of an organism within the area and an estimated amount of time the organism has been in the growth phase; and control the ultraviolet radiation generated by the ultraviolet radiation source by adjusting at least one of: a direction, an intensity, a pattern, or a spectral power of the ultraviolet radiation in response to the set of biological activity dynamics.
