Abstract: A system configured to reduce false positives when performing human presence detection is provided. In addition to calculating a Human Detection (HD) confidence score during human presence detection, the system may use human keypoint detection (HKD) techniques to calculate a true positive (TP) confidence score and detect false positives based on a combination of the two confidence scores. For example, the device system may generate keypoint data, which indicates a location and maximum confidence value for individual keypoints associated with a human body. The system may input the keypoint data to a model configured to generate the TP confidence score, such as a logistic regression model that is configured to receive numerical values as inputs (e.g., HD confidence score and 17 keypoint confidence values) and generate the TP confidence score. The system then detects false positives using the TP confidence score and may remove corresponding bounding boxes.

Abstract: A display device is provided. The display device includes a circuit board, a reflective housing, a plurality of light emitting diode units, and a diffusion film The reflective housing is disposed on the circuit board and has a plurality of recesses. The light emitting diode units are disposed in the recesses and are electrically connected to the circuit board. The diffusion film is disposed on the reflective housing and covers the recesses. The diffusion film includes a plurality of ink spots that are spaced apart from each other, and the ink spots correspond in position to the recesses.

Abstract: An autonomous mobile device (AMD) or other device may perform various tasks during operation. The AMD includes a camera to acquire an image. Some tasks, such as presenting information on a display screen or a video call, may involve the AMD determining whether a user is engaged with the AMD. The AMD may move a component, such as the camera or the display screen, to provide a best experience for an engaged user. Images from the camera are processed to determine attributes of the user, such as yaw of the face of the user, pitch of the face of the user, distance from the camera, and so forth. Based on the values of these attributes, a user engagement score is determined. The score may be used to select a particular user from many users in the image, or to otherwise facilitate operation of the AMD.

Abstract: A plurality of instances of image data can be analyzed, and favored aspects of each instance identified and utilized in generating an enhanced output image. For example, a plurality of instances of image data can be analyzed to identify metric values associated with each pixel location, such as contrast, saturation, and exposedness. A weight map corresponding to each metric is generated for each instance of image data, each weight map indicating a value for the metric at each pixel location of the instance of image data. The weight maps associated with each instance of image data are merged, and a Gaussian pyramid of the merged weight map for each instance of image data is determined along with a Laplacian pyramid for each instance of image data. The Gaussian pyramids and Laplacian pyramids are merged into a Laplacian pyramid, which is then collapsed to form an enhanced output image.

Abstract: The present invention relates to a method for treating immune disorders and a method for lowering the levels of T-cell activation and proliferation in a human comprising administering CD30 or a biologically functional equivalent thereof to a human afflicted with immune disorders. The present invention also relates to a pharmaceutical composition for treating immune disorders in a human comprising a therapeutically effective amount of CD30 or a biologically functional equivalent thereof, and a pharmaceutically acceptable carrier, excipient or diluent.
