Latest Patents

One of Su's latest patents is focused on "False positive suppression using keypoints." This system is designed to reduce false positives during human presence detection by calculating a Human Detection (HD) confidence score alongside a true positive (TP) confidence score. The system utilizes human keypoint detection (HKD) techniques to identify and eliminate false positives based on a combination of these scores. The device generates keypoint data that indicates the location and maximum confidence value for individual keypoints associated with a human body. This data is then input into a model, such as a logistic regression model, to generate the TP confidence score, which is crucial for detecting and removing false positives.

Another significant patent is for a "System to determine user engagement with autonomous mobile device." This technology allows an autonomous mobile device (AMD) to assess user engagement by analyzing images captured by its camera. The AMD can determine various attributes of the user, such as the yaw and pitch of their face and their distance from the camera. Based on these attributes, a user engagement score is calculated, which can be used to enhance the interaction experience by selecting the most engaged user or optimizing the device's operation.
