Patent number: 12368453Abstract: A multi-stage process for homomorphic end-to-end data compression and encryption is claimed. The first stage analyzes input data, applies transformations to increase compressibility and security, produces conditioned data and error streams, transforms data into a dyadic distribution, creates a transformation matrix, performs Huffman coding, and combines Huffman-encoded data with a secondary transformation stream. A second stage further processes the compressed and encrypted output, either repeating the first stage's steps or using an autoencoder for additional compression. The system supports multiple compression stages, each building on the previous one. Decompression reverses these stages while maintaining homomorphic encryption throughout. This approach enables secure data transmission, storage, and analysis in bandwidth-constrained environments, adapting to various data types and compression levels while preserving data quality and security.Type: GrantFiled: January 15, 2025Date of Patent: July 22, 2025Assignee: ATOMBEAM TECHNOLOGIES INC.Inventors: Joshua Cooper, Grant Fickes, Charles Yeomans, Brian Galvin

The first PPDU may be referred to as a PHY control PPDU and may include a physical layer control signaling field (CNT-SIG) that informs one or more stations (STAs) regarding a physical layer configuration they should use for the second PPDU. The PHY control PPDU may enable dynamic subchannel assignments for one or more identified STAs, legacy STAs, or sub-bandwidth operating devices. The techniques of this disclosure may enable sharing of a wide bandwidth wireless channel by different types of devices or different basic service sets (BSSs) assigned to different subchannels of the wireless channel.Type: GrantFiled: February 24, 2023Date of Patent: April 29, 2025Assignee: QUALCOMM IncorporatedInventors: Stephen Jay Shellhammer, Bin Tian

Patent number: 12278703Abstract: Systems and methods for data transmission protocols are disclosed. For example, a receiving device is selected to send retransmission requests when data packet loss occurs, and then a unicast transmission of data packets may be sent to that selected receiving device. Other receiving devices may be configured to receive the unicast transmission as sent to the selected receiving device and to process the transmission as a multicast transmission. Alternatively, a multicast transmission may be sent to all of the receiving devices, and the selected receiving device may be configured to process the multicast transmission as a unicast transmission for the purpose of sending retransmission requests indicating packet loss. Backup packets may be generated and sent to all of the receiving devices to improve content output quality.Type: GrantFiled: March 31, 2022Date of Patent: April 15, 2025Assignee: Amazon Technologies, Inc.Inventors: Michael Pogue, Juraj Svec, Shao-Cheng Wang
