摘要： The present invention provides a free space optical communication system that uses orthogonal modes of aberration in a laser beam as means for encoding the information. The system comprises a transmission station which transmits the user defined information in terms of the amplitudes of certain orthogonal aberration modes present in the transmitted beam. The beam then travels through free space before it reaches the receiving station. The receiving station comprises a high speed wavefront sensor of light beams. The wavefront sensor measures the amplitudes of various orthogonal aberration modes present in the incident beam at different instants of time. The amplitudes of the orthogonal modes at a certain regular time interval are then used to extract the user information.

摘要： Embodiments of the disclosure relate to a low drop diode equivalent circuit. Piezoelectric device based vibration energy harvesting requires a rectifier for conversion of input ac to usable dc form. Power loss due to diode drop in rectifier is a significant fraction of the already low levels of harvested power. The low-drop-diode equivalent can replace the rectifier diodes and minimise power loss. The diode equivalent mimics a diode using linear region operated MOSFET. The diode equivalent is powered directly from input signal and requires no additional power supply for its control. Power used by the control circuit is kept at a value which gives an overall output power improvement. The diode equivalent replaces the four diodes in a full wave bridge rectifier, which is the basic full-wave rectifier and is a part of the more advanced rectifiers like switch-only and bias-flip rectifiers.
摘要翻译：本公开的实施例涉及一种低压二极管等效电路。基于压电器件的振动能量采集需要一个整流器，用于将输入交流转换为可用的直流形式。整流二极管下降引起的功率损耗已经是已经很低的采集功率水平的很大一部分。低压二极管等效物可以替代整流二极管并最大限度地减少功率损耗。二极管等效模拟使用线性区域工作MOSFET的二极管。二极管等效电源直接由输入信号供电，不需要额外的电源供其控制。控制电路使用的功率保持在提供总输出功率的值。二极管等效替代了作为基波全波整流器的全波桥式整流器中的四个二极管，并且是更高级整流器的一部分，如开关式和偏置翻转式整流器。
