  • Publication number: 20220079472
    Abstract: Various embodiments of a fall-detection system for detecting personal fall while preserving the privacy of a detected person are disclosed. This disclosed fall-detection system can begin by receiving a sequence of video images comprising a person being monitored. The disclosed fall-detection system then processes each video image in the sequence of video images by: detecting the person in the video image; and extracting a skeletal figure of the detected person by identifying a set of human keypoints from the detected person. Next, the disclosed fall-detection system processes the sequence of skeletal figures corresponding to the sequence of video images by labeling each skeletal figure in the sequence of skeletal figures with an action among a set of predetermined actions. The disclosed fall-detection system subsequently generates a fall/non-fall decision for the detected person based on the set of action labels corresponding to the sequence of video images.

  • Publication number: 20220076394
    Abstract: The present disclosure relates to systems and methods for image processing. The system may obtain low-frequency component of a first image. For each element of the first image, the system may adjust a luminance of the element in response to determining that the luminance of the element is less than a predetermined luminance threshold. The system may determine a first luminance weight map corresponding to the first image based on the adjusted luminance of each element of the first image. The system may obtain low-frequency component of a second image and determine a second luminance weight map corresponding to the second image based on a luminance of each element of the second image. The system may further determine a fused image based on the low-frequency component of the first image, the first luminance weight map, the low-frequency component of the second image, and the second luminance weight map.

  • Publication number: 20220076429
    Abstract: In various examples, optical flow estimate (OFE) quality is improved when employing a hint-based algorithm in multi-level hierarchical motion estimation by using different scan orders at different resolution levels. A scan of an image performed with a scan order may initially leverage OFEs from a previous scan of the image, where the previous scan was performed using a different scan order. The OFEs leveraged from the previous scan are more likely to be of high accuracy until sufficient spatial hints are available to the hint-based algorithm for the scan to reduce the impact of potentially lower quality OFEs resulting from the different scan order of the previous scan.

  • Publication number: 20220073616
    Abstract: The invention is based, in part, upon the discovery of a family of antibodies that specifically bind human T Cell Immunoglobulin and Mucin Domain-3 (TIM-3). More specifically, this invention relates to a method of treating cancer by administering an anti-TIM-3 antibody in combination with an anti-PD-L1/TGF? Trap fusion protein. When administered to a human cancer patient or an animal model, the antibodies inhibit or reduce tumor growth in the human patient or animal model.

  • Publication number: 20220070516
    Abstract: A video program playing device implements a video program shielding method. The video program shielding method includes receiving a video program signal and predetermined age information, and obtaining video program information from the video program signal; determining, according to the video program information, whether the video program signal matches the predetermined age information; determining whether at least one target meeting the predetermined age information is detected within a predetermined range of a video program playing device; and stopping outputting the video program signal when the video program signal fails to match the predetermined age information and the at least one target is detected.

  • Publication number: 20220027601
    Abstract: Methods and systems are described for maintaining hygienic conditions in automatic teller machines by detecting whether or not a user is not in compliance with a hygienic standard. If a user is not in compliance, then the automatic teller machine may execute a hygienic action to cleanse the automatic teller machine. For example, the hygienic action may comprise automatically cleansing the automatic teller machine, disabling the automatic teller machine from service, transmitting a sanitation service request to an automatic teller machine provide, and/or initiating an alternative control scheme (e.g., voice controls, gesture-based controls, etc.) for the automatic teller machine.

  • Patent number: 11179064
    Abstract: Various embodiments of a vision-based privacy-preserving embedded fall-detection system are disclosed. This embedded fall-detection system can include one or more cameras for capturing video images of one or more persons. Moreover, this embedded fall-detection system can include various fall-detection modules for processing the captured video images including: a pose-estimation module, an action-recognition module, and a fall-detection module, all of which can perform the intended fall-detection functionalities within the embedded system environment in real-time in order to detect falls of the one or more persons. When a fall is detected, instead of sending the original captured images, the embedded fall-detection system can transmit sanitized video images to the server, wherein each detected person is represented by a skeleton figure in place of the actual person images, thereby preserving the privacy of the detected person.

  • Patent number: 11177700
    Abstract: The disclosure involves wireless electric power sharing between vehicles. A first vehicle sends a charging request, wherein the first vehicle is at least partially powered by a first on-board rechargeable electricity storage. The first vehicle receives a response to the charging request from a second vehicle which is at least partially powered by a second on-board rechargeable electricity storage, and a communication channel is established between the first and second vehicles. The first on-board rechargeable electricity storage is charged using energy stored in the second on-board rechargeable electricity storage and wirelessly transferred from the second vehicle to the first vehicle. The charging is controlled with information exchanged between the first and second vehicles over the communication channel.
