Patent number: 11922303Abstract: Embodiments described herein provides a training mechanism that transfers the knowledge from a trained BERT model into a much smaller model to approximate the behavior of BERT. Specifically, the BERT model may be treated as a teacher model, and a much smaller student model may be trained using the same inputs to the teacher model and the output from the teacher model. In this way, the student model can be trained within a much shorter time than the BERT teacher model, but with comparable performance with BERT.Type: GrantFiled: May 18, 2020Date of Patent: March 5, 2024Assignee: Salesforce, Inc.Inventors: Wenhao Liu, Ka Chun Au, Shashank Harinath, Bryan McCann, Govardana Sachithanandam Ramachandran, Alexis Roos, Caiming Xiong

Patent number: 10879966Abstract: A multiple-input and multiple-output (MIMO) bolt-on device for a single-input and single-output (SISO) radio, a MIMO channel emulator for testing the MIMO bolt-on device, and a MIMO channel emulation method are provided. The MIMO bolt-on device includes: a plurality of antennas, a multi-channel receiver, a plurality of couplers, a micro-controller, and a switch device. The multi-channel receiver includes a plurality of channels for signal transmission. Each coupler is configured to couple the multi-channel receiver with one of the plurality of antennas. The micro-controller is coupled to the multi-channel receiver to compare signals from the plurality of channels, thereby identifying a channel with a highest signal-to-noise (SNR) among the plurality of channels. The switch device is coupled to the micro-controller and configured to select an antenna corresponding to the channel with the highest SNR among the plurality of antennas for a connection between a selected antenna and the SISO radio.Type: GrantFiled: August 12, 2020Date of Patent: December 29, 2020Assignee: INTELLIGENT FUSION TECHNOLOGY, INC.Inventors: Zhonghai Wang, Lun Li, Jingyang Lu, Genshe Chen, Weifeng Su, Xingping Lin, Xingyu Xiang, Wenhao Xiong

Patent number: 10798651Abstract: A three-layer protocol stack in a wireless communication device and a wireless communication network are provided. The three-layer protocol stack includes a physical layer; a medium access control (MAC) layer; and a network layer. The physical layer includes one or more circuits to conduct a power consumption minimization and a waveform selection. The MAC layer is configured to perform a medium access control and a resource block reconfiguration. The network layer is configured to perform an energy efficient routing and connection maintenance. The physical layer, the MAC layer and the network layer cooperate with each other to at least reduce an energy consumption of the wireless communication device.Type: GrantFiled: August 17, 2018Date of Patent: October 6, 2020Assignee: INTELLIGENT FUSION TECHNOLOGY, INC.Inventors: Wenhao Xiong, Yi Li, Xin Tian, Dan Shen, Nichole Sullivan, Biao Chen, Genshe Chen

Patent number: 10291347Abstract: A systematic interferences mitigation design for protected satellite communications (SATCOM) is provided. An advanced channel coding is designed to provide coding gain for SATCOM even in the presence of synchronization errors because of unintentional and intentional radio frequency interferences (RFIs). A unified SATCOM system spectrum efficiency and energy efficiency performance model is developed with a unified interference model for SATCOM dynamic resource allocation (DRA). The SATCOM system DRA is designed with a game theoretic engine and link optimizations providing traffic control, power control, frequency hopping pattern selection, beamforming codebook selection, and modulation with coding agile waveform adaptations. The interferences mitigation design is implemented with software defined radio USRP and GNU-radio to maintain communication link quality of services (QoS).Type: GrantFiled: January 3, 2017Date of Patent: May 14, 2019Assignee: INTELLIGENT FUSION TECHNOLOGY, INC.Inventors: Gang Wang, Xin Tian, Zhihui Shu, Wenhao Xiong, Tien M.
