Patent number: 11701054Abstract: The present disclosure relates to systems and methods for characterizing a behavior change of a process. A behavior model that can include a set of behavior parameters can be generated based on behavior data characterizing a prior behavior change of a process. A stimulus parameter for a performance test can be determined based on the set of behavior parameters. An application of the performance test to the process can be controlled based on the stimulus parameter to provide a measure of behavior change of the process. Response data characterizing one or more responses associated with the process during the performance test can be received. The set of behavior parameters can be updated based on the response data to update the behavior model characterizing the behavior change of the process. In some examples, the behavior model can be evaluated to improve or affect a future behavior performance of the process.Type: GrantFiled: March 12, 2018Date of Patent: July 18, 2023Assignees: OHIO STATE INNOVATION FOUNDATION, ADAPTIVE SENSORY TECHNOLOGY, INC.Inventors: Zhong-Lin Lu, Yukai Zhao, Luis A.

Patent number: 9700201Abstract: Data is received characterizing a result of a first visual sensitivity test assessing capacity to detect spatial form across one or more different target sizes, and different contrasts. Using the received data, one or more first parameters defining a first estimated visual sensitivity for a first range of contrasts and a second range of spatial frequencies is determined. One or more second parameters defining a second estimated visual sensitivity for a third range of contrasts and a fourth range of spatial frequencies is determined using the one or more first parameters and a statistical inference by at least presenting a first visual stimulus, receiving a response, and determining a second visual stimulus based at least on the response and at least a rule. The one or more second parameters is provided. Related apparatus, systems, techniques and articles are also described.Type: GrantFiled: May 9, 2013Date of Patent: July 11, 2017Assignees: The Schepens Eye Research Institute, Inc., The Ohio State UniversityInventors: Peter Bex, Michael Dorr, Luis Lesmes, Zhong-Lin Lu
