His innovative approach has led to the creation of a unique patent that addresses the challenges of microphone array configurations in shared spaces.

Latest Patents

Holmgren holds a patent for a "System for dynamically determining the location of and calibration of spatially placed transducers for the purpose of forming a single physical microphone array." This audio conference system is designed to automatically form a combined physical microphone array aperture across various microphone elements in a shared three-dimensional space. The system includes multiple microphone/speaker units, each equipped with at least one microphone and/or speaker, along with a system processor that communicates with these units. The processor instructs the units to transmit unique calibration signals and calculates the time difference of arrival (TDOA) between them. This innovative approach allows for the creation of a physical array structure based on TDOA, ultimately generating a consolidated target coverage zone common to all microphone/speaker units.
