Patent number: 12335909Abstract: Ranging operations may be performed between an initiator device and a responder device using data frames as opposed to fine timing measurement (FTM) frames or Null Data Packet (NDP) frames. An initiator device may request the responder device to perform a ranging operation. The responder device may transmit a data frame to the initiator device and may receive an acknowledgement (ACK) frame from the responder device. The responder device may transmit a second data frame to the initiator device that includes ranging measurement information for the previous message exchange, including a time of departure of the data frame and a time of arrival of the ACK frame. Because data frames are encrypted, the ranging measurement information is provided in a secure manner. Moreover, by including the ranging measurement information in data frames, throughput for the ranging procedure is improved.Type: GrantFiled: July 2, 2021Date of Patent: June 17, 2025Assignee: QUALCOMM IncorporatedInventors: Rishabh Raj, Ravindra Chauhan, Xiaoxin Zhang

Patent number: 12228632Abstract: Embodiments described herein address these and other issues by providing radio frequency (RF) sensing to determine the status of a driver or other occupant of the vehicle. RF sensing may be provided by existing radios of a vehicle, such a Wi-Fi transceiver, and may therefore provide RF sensing functionality to a vehicle with little added cost. RF sensing can be leveraged to implement safety features such as detecting an unattended child or pet in a vehicle, detecting driver alertness, and the like.Type: GrantFiled: September 21, 2021Date of Patent: February 18, 2025Assignee: QUALCOMM INCORPORATEDInventors: Xiaoxin Zhang, Parthiban Ellappan, Rishabh Raj

Publication number: 20240086232Abstract: A method for managing memory for applications in a computing system includes receiving a selection of a preferred application. During user-controlled operation over the application, the transitions of selected application between foreground and background are monitored. A retention of the application in memory is triggered upon a transition of the application to background during the user operation. Retention of the application includes compressing memory portions of the application. Accordingly, the application is retained within the memory based on said compressed memory portions. A requirement to restore the retained application is sensed based on either a user selection or an automatically generated prediction and the application is restored from the retained state back to the foreground.Type: ApplicationFiled: November 21, 2023Publication date: March 14, 2024Inventors: Ganji Manoj KUMAR, Jaitirth Anthony JACOB, Rishabh RAJ, Vaisakh Punnekkattu Chirayil SUDHEESH BABU, Renju Chirakarotu NAIR, Hakryoul KIM, Shweta RATANPURA, Tarun GOPALAKRISHNAN, Sriram SHASHANK, Raju Suresh DIXIT, Youngjoo JUNG

Publication number: 20230360370Abstract: This disclosure relates to improved systems, methods, and techniques for constructing and employing neural network architectures to solve computer vision and other problems. The neural network architectures can have two or three layers with all nodes in the first layer connected to all nodes in the second layer. The nodes in the second layer can be connected to each other. The weights or values of the various connections between these nodes in the first two layers can also be updated between the processing of inputs to the neural network architectures. These neural network architectures do not require extensive training and can learn continuously. Other embodiments are disclosed herein as well.Type: ApplicationFiled: June 28, 2023Publication date: November 9, 2023Inventors: Congrong Yu, Rishabh Raj

Patent number: 11769316Abstract: This disclosure relates to the use of “pseudo-images” to perform image recognition, e.g., to perform facial image recognition. In an embodiment, the pseudo-image is obtained by starting with a real world image and, after optional preprocessing, subjecting the image to a non-linear transformation that converts the image into a pseudo-image. While real world objects (or, more generally, real world patterns) may be perceivable in the starting image, they cannot be perceived in the pseudo-image. Image recognition takes place by comparing the pseudo-image with a library of known pseudo-images, i.e., image recognition takes place in pseudo-image space without a return to real world space. In this way, robust image recognition is achieved even for imperfect real world images, such as, real world images that have been degraded by noise, poor illumination, uneven lighting, and/or occlusion, e.g., the presence of glasses, scarves, or the like in the case of facial images.Type: GrantFiled: August 7, 2021Date of Patent: September 26, 2023Assignee: Stowers Institute for Medical ResearchInventors: Congrong (Ron) Yu, Rishabh Raj, Dar Wilbur Dahlen

Patent number: 11582511Abstract: Techniques are provided for performing radio frequency (RF) sensing to determine the viewing status of a television user. This can be used to determine user behavior during the playback of content (e.g., whether a user is watching the content), which can be used as a data point for determining the user's level of interest in the content. Using the status of the television user, embodiments can provide additional or alternative functionality, such as powering down and/or powering up the television. Furthermore, RF sensing may be performed by existing television hardware, such a Wi-Fi transceiver, and may therefore provide RF sensing functionality to a television with little or no added cost.Type: GrantFiled: March 15, 2021Date of Patent: February 14, 2023Assignee: QUALCOMM IncorporatedInventors: Xiaoxin Zhang, Rishabh Raj, Parthiban Ellappan
