Patent number: 11923092Abstract: 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.Type: GrantFiled: November 23, 2021Date of Patent: March 5, 2024Assignee: Altum View Systems Inc.Inventors: Andrew Tsun-Hong Au, Dong Zhang, Chi Chung Chan, Jiannan Zheng

Patent number: 11163875Abstract: The present disclosure relates to using correlations between support interaction data and telemetry data to discover emerging incidents for remediation. One example method generally includes receiving a corpus of support interaction data and a corpus of telemetry data. Topics indicative of underlying problems experienced by users of an application are extracted from the corpus of support interaction data. A topic having a rate of appearance in the support interaction data above a threshold value is identified. A set of telemetry data relevant to the topic is extracted from the corpus of telemetry data, and a subset of the relevant set of telemetry data having a frequency in the relevant set of telemetry data above a second threshold value is identified. The topic and the subset of telemetry data are correlated to an incident to be remediated, and one or more actions are taken to remedy the incident.Type: GrantFiled: March 22, 2019Date of Patent: November 2, 2021Assignee: CA, INC.Inventors: Kevin A.

Patent number: 10689426Abstract: Disclosed is a polypeptide containing an extracellular domain of a synaptogenic protein, and a method for manufacturing a nerve cell, a complex containing a biotin tagged at the C-terminus of the polypeptide, an artificial synapse inducer for coupling the composite to a streptavidin (SAV)-coated substrate and a nerve cell. The complex tagged with a biotin at the C-terminus of the polypeptide containing the extracellular domain of the synaptogenic protein, such as neuroligin-1, can display activity by being attached to the SAV-coated substrate to adjust the orientation thereof without help of a supported lipid bilayer. The complex containing an additional RFP between the extracellular domain and the biotin of the synaptogenic protein not only facilitates easier mass-production, quantification, and tracking, but also displays activity of a normal synaptogenic protein, thereby inducing excitatory or inhibitory synaptic differentiation by being fixed to the substrate and added to the nerve cell culture.Type: GrantFiled: October 9, 2018Date of Patent: June 23, 2020Assignee: Seoul National University R&DB FoundationInventors: Taek Dong Chung, In Seong Hwang, Eun Joong Kim, Chang Su Jeon
