Patent number: 11903027Abstract: The present disclosure relates to several techniques for reducing the occurrence of data collisions, which can occur when multiple devices simultaneously transmit data in the same (frequency) channel. For example, a turnaround time in which a device switches from a receive mode of operation to a transmit mode of operation may be reduced based on the device and another device indicating that they are capable of operating with a reduced turnaround. As another example, devices may use learning-based turnaround estimation to determine a turnaround time supported by other devices and utilize the determined turnaround time, for instance, instead of a longer turnaround time. As yet another example, multiple clear channel assessments may be performed before transmitting data. For instance, a first clear channel assessment may be performed during a backoff period, and a second clear channel assessment may be performed afterwards before data is transmitted.Type: GrantFiled: March 17, 2022Date of Patent: February 13, 2024Assignee: Apple Inc.Inventors: Sarvesh Kumar Varatharajan, Arun Vijayakumari Mahasenan, Venkateswara Rao Manepalli, Won Soo Kim, Yaranama Venkata Ramana Dass, Giri Prassad Deivasigamani, Anil G Naik, Piyush Kumar Upadhyay

Publication number: 20230262574Abstract: Embodiments disclosed herein relate to enabling direct wireless device-to-device communication between sleepy end devices (SEDs) of a mesh (e.g., Thread®) network. A router may forward packets between end devices of the mesh network. However, if the router is not available, SEDs may not be able to communicate with each other using a mesh protocol. Embodiments presented herein enable end devices of the mesh network to communicate directly, without a router. Some embodiments are directed to changing a role of an end device to temporarily act as a router for a particular target end device. The role change may be based on a trigger event and may be temporary until a target action is performed by the target end device. In some embodiments, the end devices continue to operate as SEDs and use coordinated sampled listening techniques to communicate via the mesh protocol.Type: ApplicationFiled: February 11, 2022Publication date: August 17, 2023Inventors: Arun Vijayakumari Mahasenan, Sarvesh Kumar Varatharajan, Venkateswara Rao Manepalli, Yaranama Venkata Ramana Dass

Publication number: 20230105762Abstract: An approach is described for a wireless device comprising a transceiver and a processor communicatively coupled to the transceiver. In a thread-based device, a thread radio coexists with a primary radio, such as a Bluetooth or WiFi radio. Because both radio share a common frequency band, the thread radio requests grants from the primary radio for transmission and reception. So as to avoid bogging down the primary radio, the thread radio throttles its requests. Specifically, the thread radio tracks certain variables indicative of the number of requests that have been made within a time window and the types of requests that have been made to the primary radio. By limiting the number of total requests and the number of requests of each type within the time window, the thread radio avoids overburdening the primary radio.Type: ApplicationFiled: August 16, 2022Publication date: April 6, 2023Applicant: Apple Inc.Inventors: Venkateswara Rao MANEPALLI, Yaranama Venkata Ramana DASS, Sarvesh Kumar VARATHARAJAN

Publication number: 20230094988Abstract: An approach is described for a wireless device comprising a transceiver and a processor communicatively coupled to the transceiver. In a thread-based mesh network, a transmitting device occasionally transmits various multicast messages to the network for the purpose of maintaining the network. Of these messages, the mesh link establishment (MLE) advertisement message is particularly important as it notifies neighbor routers as to the presence and function of the transmitting device. Therefore, the transmitting device of the present disclosure transmits its MLE advertisement message to the network multiple times within a given time window. Additionally, the message is transmitted each time with a same identifier. A recipient device stores the identifier of each most recent MLE advertisement message. The identifier of each subsequently received MLE advertisement is compared to the stored identifier. This allows the recipient device to determine whether the message has been previously received.Type: ApplicationFiled: August 16, 2022Publication date: March 30, 2023Applicant: Apple Inc.Inventors: Venkateswara Rao MANEPALLI, Manuel Roman CUESTA, Yaranama Venkata Ramana DASS, Sarvesh Kumar VARATHARAJAN

Patent number: 11498038Abstract: The invention relates to Quench box assembly comprising quench pipe and quench box, to mix quench gas and vapor-liquid effluent from previous catalyst bed to achieve equilibrium temperature before entering the next bed. The quench pipe is in the form of ring having aperture while quench box consists of swirling section and a mixing chamber. The swirling section consists of inclined baffles to provide swirling action to incoming stream and the turbulence created by the swirling action increases the heat transfer rate thus requiring the smaller reactor volume to attain equilibrium temperature. The perforated plate being open from all the sides allowing the liquid to flow uniformly from all directions thus providing uniform distribution on the distributor tray. Hence, eliminates the requirement of rough liquid distributor before the distribution tray.Type: GrantFiled: June 30, 2021Date of Patent: November 15, 2022Assignee: Indian Oil Corporation LimitedInventors: Pravesh Kumar, Ramesh Karumanchi, Sarvesh Kumar, Madhusudhan Sau, Gurpreet Singh Kapur, Sankara Sri Venkata Ramakumar
