Patent number: 11980792Abstract: Systems, computer-implemented methods, and computer program products that can facilitate calibrating a user activity model of a user device nodes are described. According to an embodiment, a method for calibrating a user activity model used by a mobile device can comprise receiving sensor data from a sensor of the mobile device. Further, applying a first weight to a first a first likelihood of a first occurrence of a first activity, wherein the first likelihood is determined by a first estimator of the user activity model by applying preconfigured criteria to the sensor data. The method can further comprise performing an action based on a determination of the first occurrence of the first activity, the determination being based on the first weight and the first likelihood of the first occurrence of the first activity.Type: GrantFiled: September 25, 2019Date of Patent: May 14, 2024Assignee: QEEXO, CO.Inventors: Karanpreet Singh, Rajen Bhatt

Publication number: 20240137466Abstract: A videoconference system acquires images during a videoconference. A still image may be analyzed to identify persons participating in the videoconference. A first frame is generated for each person and represents a subsection of an image that focuses on the face of that person. These first frames may include unpleasant components. Background segmentation is performed on each first frame to remove or diminish such unpleasant components. For example, a second frame for a person may be generated by identifying the background segments in the first frame and blurring or replacing such background segments with a virtual background. When the second frames are put together, the differences in the first frames are obscured making it more pleasing to view. A composite stream of the second frames is generated, per layout rules, and sent to the far side for improved viewing of the participants at the far side.Type: ApplicationFiled: October 19, 2022Publication date: April 25, 2024Inventors: RAJEN BHATT, KUI ZHANG

Patent number: 11847775Abstract: Provided are various mechanisms and processes for automatic computer vision-based defect detection using a neural network. A system is configured for receiving historical datasets that include training images corresponding to one or more known defects. Each training image is converted into a corresponding matrix representation for training the neural network to adjust weighted parameters based on the known defects. Once sufficiently trained, a test image of an object that is not part of the historical dataset is obtained. Portions of the test image are extracted as input patches for input into the neural network as respective matrix representations. A probability score indicating the likelihood that the input patch includes a defect is automatically generated for each input patch using the weighted parameters. An overall defect score for the test image is then generated based on the probability scores to indicate the condition of the object.Type: GrantFiled: December 9, 2022Date of Patent: December 19, 2023Assignee: QEEXO, CO.Inventors: Rajen Bhatt, Shitong Mao, Raviprakash Kandury, Michelle Tai, Geoffrey Newman

Publication number: 20230351727Abstract: A method including detecting, in a digital image, a set of sub-images matching a selected object type. The method also includes generating a first confidence score that a first sub-image in set of sub-images matches a selected object type. The method also includes generating a second confidence score that a second sub-image in set of sub-images matches the selected object type. The method also includes generating a similarity measure by comparing the first sub-image to the second sub-image. The method also includes removing, responsive to the similarity measure exceeding a similarity threshold value and the first confidence score exceeding the second confidence score, the second sub-image from the set of sub-images. The method also includes processing, after removing, the digital image using the set of sub-images.Type: ApplicationFiled: May 2, 2022Publication date: November 2, 2023Applicant: Plantronics Inc.Inventors: Raghavendra Balavalikar Krishnamurthy, Rajen Bhatt, David Bryan, Yong Yan

Publication number: 20230342433Abstract: Disclosed are apparatus and methods for automatically training a sensor node to detect anomalies in an environment. An indication is sent to the sensor node to initiate training by the sensor node to detect anomalies in object(s) in the environment based on sensor data generated by a sensor operable to detect signals from the one or more objects in the environment. After training is initiated, the sensor node automatically trains a model in communication with the sensor to detect anomalies in the one or more objects in the environment, wherein such training is based on the sensor data. After the model is trained, the model to detect anomalies in the object(s) in the environment is executed by the sensor node.Type: ApplicationFiled: June 26, 2023Publication date: October 26, 2023Applicant: QEEXO, CO.Inventors: Karanpreet Singh, Rajen Bhatt

Patent number: 11777754Abstract: The number of persons in a still image acquired during a videoconference may change over time due to movement or persons entering or exiting a conference room. Minimizing the number of person identifiers that are tracked is beneficial for framing purposes. Typically, a stream of frames is sent to a far side, such as another endpoint device, for viewing. If the number of persons identified keeps changing, the composition of the stream of frames will be constantly changing as well. By using person identification and the use of timers, movement by the same person or a temporary change in a number or set of persons may be detected without making changes to the number of identifiers and persons being framed. It is only when a change has persisted past a period of time that changes are made to the frames, thereby improving the overall viewing experience.Type: GrantFiled: October 24, 2022Date of Patent: October 3, 2023Assignee: Plantronics, Inc.Inventors: Kui Zhang, Raghavendra Balavalikar Krishnamurthy, Rajen Bhatt

Publication number: 20230245077Abstract: Providing a facilities supervisor notice after a conference room or other common area has been used and is in a messy condition. An image of the conference room obtained after use is evaluated to determine if the conference room is neat. A neatness score is obtained for the conference room. If the score indicates a neatness value above a settable level, the conference room is considered clean and ready for use. If the neatness score indicates a neatness value less than the settable level, the conference room is not ready for use, and a notice is provided to the facilities supervisor to allow a cleaning person to be dispatched. The need to perform the cleanliness or neatness review is triggered by referencing scheduled meetings in a calendaring system, by monitoring the conference room for the presence of individuals having an unscheduled meeting and periodically or randomly.Type: ApplicationFiled: January 31, 2022Publication date: August 3, 2023Inventors: Rajen BHATT, Donald L.

Publication number: 20230060798Abstract: The attention level of participants is measured and then the resulting value is provided on a display of the participants. The participants are presented in a gallery view layout. The frame of each participant is colored to indicate the attention level. The entire window is tinted in colors representing the attention level. The blurriness of the participant indicates attention level. The saturation the participant indicates attention level. The window sizes vary based on attention level. Color bars are added to provide indications of percentages of attention level over differing time periods. Neural networks are used to find the faces of the participants and then develop facial keypoint values which are used to determine gaze direction, which in turn is used to develop an attention score. The attention score is then used to determine the settings of the layout.Type: ApplicationFiled: July 22, 2022Publication date: March 2, 2023Inventors: Jian David Wang, Rajen Bhatt, Kui Zhang, Thomas Joseph Puorro, David A.
