Title: Herman P Briar: Innovator in Speech Analysis and Rocket Propellant Measurement
Introduction
Herman P Briar is a notable inventor based in Rancho Cordova, CA (US). He holds a total of 3 patents that showcase his contributions to the fields of speech analysis and telemetry for rocket engines. His innovative work has had a significant impact on technology and engineering.
Latest Patents
One of Briar's latest patents is a method and apparatus for speech analysis. This invention performs speech analysis by synchronizing with the initiation of glottal pulses produced during the voicing of phonemes. The analysis is conducted entirely within a pitch period, focusing on the three most dominant formant frequencies involved in the enunciation of voiced phonemes. The peaks in the transform represent formant frequencies, and three peaks are selected to identify the frequencies with the greatest amplitudes. The invention also includes a unique set of phoneme identifications derived from various factors, enabling advanced phoneme encoding and speech reproduction.
Another significant patent is the in-situ measurement apparatus. This telemetry apparatus is designed for measuring dynamic moduli, which is a key design parameter of the propellant mass in solid fuel rocket engines. This invention is crucial for enhancing the performance and safety of rocket propulsion systems.
