Title: Innovations by Sunil K Gupta
Introduction
Sunil K Gupta is a notable inventor based in Edison, NJ (US). He holds a total of 9 patents that showcase his contributions to the fields of encryption technology and speech therapy. His innovative work has made significant impacts in both cryptography and e-commerce.
Latest Patents
One of Gupta's latest patents is titled "Bit based arithmetic coding using variable size key cipher." This invention involves an encryption device and method that implement a bit-based encryption scheme. The device includes a random number generator that receives a main key, determines a working key using at least one random number, and outputs this working key. It also features a model that generates frequency counts based on the main key, working key, and plain text to be encoded. The encoder outputs encoded text based on these inputs. This encryption method processes text based on a stream structure with an unlimited key length, making it adaptable to various environments.
Another significant patent is "Intonation transformation for speech therapy and the like." This invention modifies the intonation of speech through a combination of resampling and time-domain harmonic scaling. By increasing or decreasing the number of data points in a signal, the pitch of a speech signal can be adjusted. This technology can be implemented in automated speech-therapy tools, allowing users to improve their pronunciation by emphasizing the correct intonation of words or phrases.
