Patent number: 11606760Abstract: A radio node may transmit a signal using a transmit power. Then, the radio node may adjust the transmit power within a range of values. The adjustment may include reducing the transmit power when a spatial received signal strength indication (RSSI) metric of the radio node is greater than a first threshold value and a coverage criterion is met. Note that the spatial RSSI metric of the radio node may correspond to a set of temporal RSSI metrics of the radio node received from neighboring radio nodes. Moreover, the coverage criterion may be that less than a portion of RSSI measurements of the radio node associated with electronic devices, which are communicatively attached with the radio node, is less than a second threshold value. Alternatively, the adjustment may include increasing the transmit power when the spatial RSSI metric is less than the first threshold value.Type: GrantFiled: March 12, 2021Date of Patent: March 14, 2023Assignee: ARRIS Enterprises LLCInventors: Utsaw Kumar, Shailender Potharaju, Paul Petrus

Patent number: 11604944Abstract: In various examples, systems and methods are disclosed that preserve rich spatial information from an input resolution of a machine learning model to regress on lines in an input image. The machine learning model may be trained to predict, in deployment, distances for each pixel of the input image at an input resolution to a line pixel determined to correspond to a line in the input image. The machine learning model may further be trained to predict angles and label classes of the line. An embedding algorithm may be used to train the machine learning model to predict clusters of line pixels that each correspond to a respective line in the input image. In deployment, the predictions of the machine learning model may be used as an aid for understanding the surrounding environment—e.g., for updating a world model—in a variety of autonomous machine applications.Type: GrantFiled: July 17, 2019Date of Patent: March 14, 2023Assignee: NVIDIA CorporationInventors: Minwoo Park, Xiaolin Lin, Hae-Jong Seo, David Nister, Neda Cvijetic

Patent number: 11595434Abstract: Disclosed herein are methods and systems that apply a multi-layer Hidden Markov Model (HMM) for intrusion detection. The methods and systems employ a dimension reduction technique to extract only important features from network packet data and apply a decomposition algorithm to lower levels of data to construct lower level HMMs (representing partial solutions), which lower level HMMs are then combined to form a final, global solution. The multi-layer approach can be expanded beyond the exemplary case of 2 layers in order to capture multi-phase attacks over longer spans of time. A pyramid of HMMs can resolve disparate digital events and signatures across protocols and platforms to actionable information where lower layers identify discrete events (such as network scan) and higher layers identify new states which are the result of multi-phase events of the lower layers.Type: GrantFiled: May 29, 2020Date of Patent: February 28, 2023Assignee: Morgan State UniversityInventors: Wondimu K.
