Patent number: 10362215Abstract: The present invention discloses a microscopic three-dimensional measurement system and method based on a moving diaphragm. The present invention adds the diaphragm into the existing optical microscopic imaging system to limit light irradiation angle during imaging for reducing the diameter of blur circle, which extends the depth of field and the depth measurement range, so as to achieve the three-dimensional measurement of large-size objects to be measured. Through changing the position of the added diaphragm, two images with different light incident directions are obtained, which is similar to binocular stereo vision, and then the disparity map is used to predict the depth, so as to carry out the 3D scene reconstruction. Since the depth of field of the imaging system is enlarged and the imaging model has certain non-linear characteristics, the present invention uses quadratic function to express the non-linearity, which reduces the measurement error.Type: GrantFiled: February 12, 2018Date of Patent: July 23, 2019Assignee: Ningbo UniversityInventors: Gangyi Jiang, Mei Yu, Shengli Fan, Yigang Wang

Patent number: 10256628Abstract: A controller and method are usable to control the provision of electrical power from a local electrical network to a power grid. If it is determined that changes in the power grid voltage are correlated with the provision of power to the power grid, the power that is being provided to the power grid is manipulated so that the rate of change of the wattage that is provided to the power grid does not exceed a predetermined ramp rate. Such a manipulation is accomplished by adjusting an operational parameter of one or more electrical loads that are connected with the local electrical network.Type: GrantFiled: October 23, 2015Date of Patent: April 9, 2019Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Yigang Wang, Roger Wayne Rognli

Patent number: 10082814Abstract: A method of operating an electrical feeder permits the electrical feeder voltage to be maintained at the minimum voltage within a voltage range based upon dynamic grouping together of electrical generators on the electrical feeder with demand response loads on the electrical feeder. A method of assessing the proper operation of a voltage control device on the electrical feeder involves detecting a number of properties of the electrical power in the electrical feeder both prior to and subsequent to a change in an operational parameter of a voltage control device. An expected effect upon the electrical feeder of one or more distributed generators is filtered from this in order to determine a net effect of the voltage control device itself on the electrical feeder. Based upon the detected net effect and a predicted baseline effect for the voltage control device, it can be determined whether the voltage control device is functioning properly.Type: GrantFiled: March 3, 2016Date of Patent: September 25, 2018Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Dongbo Zhao, Yigang Wang, Chinmaya Baburao Patil
