  • Patent number: 7843565
    Abstract: A frequency modulated spectroscopy system, including a photo-detector, a band-pass filter to filter the output of the photo-detector, and a rectifier to demodulate. The band-pass filter has a relatively high Q factor. With the high Q factor band-pass filter and rectifier, a reference sinusoid is not required for demodulation, resulting in phase-insensitive spectroscopy. Other embodiments are described and claimed.

  • Publication number: 20080134679
    Abstract: A solar powered turbine driven electric generator system. The system generates electrical power by collecting solar energy through the surfaces of an inflatable solar energy collector structure. The collected heat boils a working fluid contained inside the collector structure, generating pressurized vapor. The pressurized vapor drives a turbine/generator, generating electrical power. After the vapor crosses the turbine the excess heat in the vapor is radiated to space, condensing the vapor back to liquid, which is recycled to the collector structure. This form of power system can be scaled to higher levels of power generation in nearly a linear manner by increasing the surface area of the collectors, radiator area, and the capacity of the turbine and generator.
