Abstract: Systems and methods provide for capturing and presenting content creation tools of an application used in a video. Application data from the application for the duration of the video is received. The application data includes data identifiers and time markers corresponding to user interaction with an application in a video. The application data is processed to detect tool identifiers identifying tools used in the video based on the data identifiers. For each a tool identifier, a tool label and a corresponding time in the timeline is determined. A tool record storing the tool labels and the corresponding times in association with the video is generated. When a viewer requests to watch the video, the tool record is presented to the viewer in conjunction with the video.

Abstract: A low-frequency band suppression enhanced anti-reversal power system stabilizer is presented by the invention. Currently the widely used PSS2B power system stabilizer needs lead elements above Order 2 to meet the phase compensation requirement of DC blocking signal of active power, thus quickly increasing high-frequency band gain, restricting allowable total setting gain of PSS, limiting low-band gain and reducing low-frequency band suppression ability of power system stabilizer. The invention will add generator speed signal ? (which is treated by DC blocking element and corrected by parallel proportional differential PD) and active power signal Pe (which is treated by DC blocking element and gained by gain factor Ks3) to get equivalent synthetic mechanical power of power system stabilizer.
