Publication number: 20200004983Abstract: Techniques disclosed herein encrypt sensitive data being transmitted from one endpoint to another endpoint through intermediary cloud(s) so that the sensitive data is not visible to the intermediary cloud(s). Double data encryption, utilizing public and private key pairs generated at the endpoints, is used to anonymize the sensitive data, while other data transmitted along with the sensitive data remains unencrypted so that intermediary cloud(s) can process the unencrypted data. In a particular embodiment, one of the endpoints is an application running in a first cloud, the other endpoint is a web browser executing a web application, and the intermediary cloud(s) are additional cloud(s) with applications running therein that provide services to the first cloud or coordinate with the application running in the first cloud to provide a service.Type: ApplicationFiled: June 29, 2018Publication date: January 2, 2020Inventors: Wei CHEN, Hongqiang CHEN, Jun SUN

Patent number: 10232473Abstract: A system and method for performing laser induced breakdown spectroscopy during laser ablation of a coating, such as a TBC coating, deposited on a surface of a component, particularly to enable obtained spectrometry signals of the ablated coating to be used to monitor and control the laser ablation removal process in real-time. The system includes a laser energy source and a scan head interconnected with the laser energy source to receive a laser beam therefrom and then direct the laser beam onto the surface of the coated component. Collection optics collect radiation emitted from a laser-induced plasma generated by the laser beam at the surface of the coated component. The system is further equipped to spectrally analyze the radiation and generate a feedback signal for control and optimization of one or more operational parameters of the laser energy source in real-time.Type: GrantFiled: February 26, 2016Date of Patent: March 19, 2019Assignee: General Electric CompanyInventors: Ying Zhou, Hongqiang Chen, Matthew Vaughan Schulmerich, Jason Christopher Gritti
