摘要:
A ultra high speed photonic Analog to Digital Converted (ADC) for sampling and quantizing an electrical voltage signal, internally enabled by photonics uses coherent optical detection architectures for photonic quantization. Coherent light is phase modulated by the test signal. Using an interferometer, or an array of interferometers the phase of modulated light is compared with a reference light. Flash ADC, successive approximation ADC and delta-sigma ADC configurations are presented.
摘要:
A small to medium size system for wing energy harvesting, storing and generating electricity is disclosed. The system uses a wind turbine situated on a mast to capture wind energy and hydraulic power transmission to transmit the energy to a compressor which compresses atmospheric air. Heat generated by the compressing of air is removed by heat exchanging with water and stored in hot water container. The cooled compressed air is stored in a compressed air tank. On demand, the compressed air is released and heated by the stored hot water, then used to power a generator using a pneumatic motor. Solar heater is used to further heat the water. Water and liquefied CO2 are removed from the compressed air. Hydrostatic, variable displacement power transmission system allows the wind turbine to rotate at speeds proportional to wind velocity and to capture the maximum possible energy from light and fast winds.
