Latest Patents

Among his latest inventions, two patents stand out:

1. **Priority-based Video Encoding and Transmission**: This innovation involves a video encoding system that decomposes pixel data into frequency bands before encoding. These frequency bands are organized into blocks, which are then encoded by a block-based encoder. The encoded blocks are sent to a wireless interface, where they are packetized for transmission. Notably, this invention allows for the categorization of encoded frequency bands into multiple priority levels, adding tags with metadata to each block to indicate the frequency band represented, its priority, and timing information. This enables the wireless interface to prioritize packet transmission based on these criteria.

2. **Ranging Using Beamforming Antenna Weight Vectors and Secure Ranging Packet with Phase Tracking**: This patent focuses on secure time-of-flight measurements for wireless communication. It includes secure ranging packets that use zero-padded random sequence waveforms, effective even at higher frequency bands like 60 GHz, in non-line-of-sight scenarios. The invention offers a flexible protocol for negotiating security and operational parameters. Key features include phase tracking to mitigate phase noise at higher frequencies and consistency checks for random sequences used in secure ranging.
