Latest Patents

One of David Sheby's latest patents is titled "Method and apparatus for heavy-tailed waveform generation used for communication disruption." This invention addresses the challenge of countering improvised explosive devices (IEDs) that are triggered remotely through radio frequency signals. The technology exploits the characteristics of commercial cell phones and remote control devices, optimizing the matched filter for Gaussian noise by introducing specific non-Gaussian noise. This innovation leads to a family of jamming waveforms that are more effective against various digital and analog communication systems.

Another significant patent is "Process and apparatus for improved interference suppression in echo-location and imaging systems." This invention focuses on shaping transmitted signal waveforms to achieve better interference suppression. By doing so, it allows for more accurate range estimates and image formation. The shaping of the transmitted signal can be accomplished through two methods: convolving an elemental waveform with a multi-level pseudorandom sequence or transforming the amplitude of the elemental waveform nonlinearly. These specially shaped waveforms can also enhance message transmission accuracy in communication systems.
