  • Patent number: 11386337
    Abstract: A method, system, and non-transitory compute readable medium for hidden evidence correlation and causation linking including a forecasting device configured to forecast hidden evidence found in relation to a user input in hidden cycle measurements into future forecasted cycle measurements, where the forecasted hidden cycles are transformed into an amplitude versus frequency histogram with each histogram being compared to each other histogram and determined if causation is a candidate, and if causation is a candidate, a probability density function is applied to produce a degree of causation of a causation link for the hidden evidence in relation to the user input.

  • Publication number: 20220171510
    Abstract: Described herein are techniques that may be used to automate testing of services on mobile devices using visual analysis. In some embodiments, a behavioral model or other machine learning model is trained using training data collected while testers use mobile devices to test the services. During execution of a testing routine on a mobile device, screenshots are obtained of a screen of the mobile device and provided to the machine learning model. The behavioral model or other machine learning model can use the provided screenshot to determine an action that simulates a user action (e.g., a user touch on the screen of the mobile device) at a location of an icon or other visual element associated with the testing routine. These steps are repeated until an end-state of the testing routine is detected.

  • Patent number: 11302271
    Abstract: A method for driving display panel and a driving device are disclosed. A transition period is inserted between displaying two neighboring frames, pixels in the nth row to the Nth row of the display panel are switched on simultaneously in the transition period, and a voltage with the highest grayscale is applied to the pixels which are switched on. This is equivalent to turning the grayscale of pixels in the nth row to the Nth row into the highest grayscale after displaying a frame and before displaying a next frame. This can improve the response time of pixels in the nth row to the Nth row during displaying the next frame, and thus can increase the display quality of the display panel.
