I got this clue from AC 1686 on a previous page. Look at this photo of the hotel. Do you see "The Invisible Light Agency" in the center? Zoom in all the way in satellite view.

That led me to this page.

And that led to this... Daylight Solutions
"Nov 16, 2005 -
Daylight Solutions, a start-up company not even a year old, is addressing some of the most urgent and vexing problems of the 21st century ---- explosives hidden by terrorists and diseases ---- with beams of invisible light."

"The company is developing a portable sensor that uses an infrared laser to detect airborne molecules, including those from hidden explosives, dangerous gases and disease-causing microbes. The laser can be tuned while in use to quickly detect many different molecules at once, said Paul Larson, president and chief executive of the Poway-based company."

"The grant came from the San Diego-based Center for Commercialization of Advanced Technology, or CCAT San Diego. Formed in 1999, the agency is funded by the Department of Defense to encourage development of technologies that have both security and commercial applications. Its partners include San Diego State University, UC San Diego, the Space and Naval Warfare Systems Center (SpaWar) and Lockheed Martin Orincon Technologies Inc."
