Abstract: A solar cell simulator that is cylindrically symmetrical to test photovoltaic devices that are flexible. A particular embodiment would be made from plexiglass or similar acrylic material. The present invention produces a spectrum that simulates the spectral distribution of solar light that we observe on the Earth's surface. The simulator would be comprised of a tubular pulsed light source, a pulsed power supply, a tubular light spectrum filter, an IV electrical measurement station, a cylinder-shaped module holder to place the flexible large-area module during the measurement. All cylinders share the same central axis. This maintains radial uniformity of all light intensity and can be used for electrical measurements (IV curves under illumination) of flexible large-area PV modules.

Abstract: The disclosure describes a high-temperature optical transducer capable of acquiring input variables for closed-loop control of combustion systems. The key components of the innovation are a high-temperature, embedded photodiode, the use of low-cost, integral absorption filters; and the use of an embedded high-temperature preamplifier circuit. These components are combined in an optical-to-electrical signal transducer deployed in the high-temperature combustion environment, thus avoiding the high costs of optical signal transmission. The optical signals to the transducer are employed to recognize events in real-time such as the ignition spark, the start of combustion, end of combustion, misfires, and knocking. The outputs from the transducer may be used in a statistical fashion to control engine roughness and cyclic stability. By resolving specific colors in the flame, the optical sensors may also be used to determine the temperature and the emission production in the combustion chamber.
