Patent number: 11496419Abstract: Examples described herein relate to a reliable transport protocol for packet transmission using an Address Family of an eXpress Data Path (AF_XDP) queue framework, wherein the AF_XDP queue framework is to provide a queue for received packet receipt acknowledgements (ACKs). In some examples, an AF_XDP socket is to connect a service with a driver for the network device, one or more queues are associated with the AF_XDP socket, and at least one of the one or more queues comprises a waiting queue for received packet receipt ACKs. In some examples, at least one of the one or more queues is to identify one or more packets for which ACKs have been received. In some examples, the network device is to re-transmit a packet identified by a descriptor in the waiting queue based on non-receipt of an ACK associated with the packet from a receiver.Type: GrantFiled: April 23, 2021Date of Patent: November 8, 2022Assignee: Intel CorporationInventors: Shaopeng He, Cunming Liang, Jiang Yu, Ziye Yang, Ping Yu, Bo Cui, Jingjing Wu, Liang Ma, Hongjun Ni, Zhiguo Wen, Changpeng Liu, Anjali Singhai Jain, Daniel Daly, Yadong Li

Publication number: 20210232528Abstract: Examples described herein relate to an apparatus comprising: a descriptor format translator accessible to a driver. In some examples, the driver and descriptor format translator share access to transmit and receive descriptors. In some examples, based on a format of a descriptor associated with a device differing from a second format of descriptor associated with the driver, the descriptor format translator is to: perform a translation of the descriptor from the format to the second format and store the translated descriptor in the second format for access by the device. In some examples, the device is to access the translated descriptor; the device is to modify content of the translated descriptor to identify at least one work request; and the descriptor format translator is to translate the modified translated descriptor into the format and store the translated modified translated descriptor for access by the driver.Type: ApplicationFiled: March 22, 2021Publication date: July 29, 2021Inventors: Patrick G.

Patent number: 10378965Abstract: A system (100) for monitoring a temperature of an electrical conductor of an electrical cable and including a temperature sensor unit (100a) and a transceiver unit (100b). The temperature sensor unit (100a) is located inside the first (semi)conductive layer and includes a micro-controller (120), a temperature sensor (110), an energy harvest sub-unit (140) and a wireless transmitter layer (130). The temperature sensor (110) is adapted to detect a first signal (S1) representing temperature of the electrical conductor and to supply the first signal (S1) to the micro-controller (120). The transceiver unit (100b) is located outside the first (semi)conductive layer and includes an energy transmitter (160) and a wireless receiver (150). The energy harvest sub-unit (140) is adapted to harvest electromagnetic power from the energy transmitter (160) and to provide electrical power to the micro-controller (120).Type: GrantFiled: September 11, 2013Date of Patent: August 13, 2019Assignee: 3M Innovative Properties CompanyInventors: Zhiguo Wen, Zheng Huang, Sihua Yuan, Xuetao Yu, Ming Zhang

Patent number: 9885618Abstract: A system for monitoring temperature of an electrical conductor (31) enclosed in at least a (semi)conductive layer (13) comprising: a passive inductive unit (20), and a transceiver unit (40) and a control unit (50). The passive inductive unit (20) includes at least one temperature sensitive component and is configured to have a resonance frequency and/or Q value that vary with temperature of the electrical conductor (31). The transceiver unit (40) is configured to be electromagnetically coupled to the passive inductive unit (20) and to send out a signal representing the resonance frequency and/or Q value of the passive inductive unit (20). The transceiver unit (40) is further configured to communicate with the control unit (50) which ascertains the signal representing one or both of the resonance frequency and Q value, and which determines a value of the temperature of the electrical conductor (31) based on the ascertained signal representing one or both of the resonance frequency and Q value.Type: GrantFiled: May 3, 2013Date of Patent: February 6, 2018Assignee: 3M Innovative Properties CompanyInventors: Zhiguo Wen, Zheng Huang, Sihua Yuan, Justin M.
