A mobile network device creates and continuously modifies an anonymous user profile from collected network data and subsequently shares the profile with content providers. The mobile network device includes multiple collector devices that monitor data from routers on the mobile data network for application-level activity and a corresponding IP address or mobile phone number. The collectors then analyze the content involved with the activity and correlate it to an IP-address-phone-number pair to create a user profile. Each collector then modifies the user profile with the user's location information at the time the activity was requested. Each collector subsequently transforms the user profile into an anonymous user profile vector and shares it with the profile manager. By repeating this process over time, the collectors create and modify an anonymous user profile vector that can be shared with content providers for targeted advertising.

Increased utilization of solar power is highly desirable as solar power is a readily available renewable resource with power potential far exceeding total global needs; and as solar power does not contribute to pollutants associated with fossil fuel power, such as unburned hydrocarbons, NOx and carbon dioxide. The present invention provides low-cost inflatable heliostatic solar power collectors, which can be stand-alone units suitable for flexible utilization in small, medium, or utility scale applications. The inflatable heliostatic power collectors use a reflective surface or membrane “sandwiched” between two inflated chambers, and attached solar power receivers which may be of photovoltaic and / or solar thermal types. Modest concentration ratios enable benefits in both reduced cost and increased conversion efficiency, relative to simple prior-art flat plate solar collectors.
