Brian C Donnelly

Title: Brian C Donnelly: Innovator in Imaging Systems and User Interfaces

Introduction

Brian C Donnelly is a notable inventor based in Sudbury, MA, with a focus on advancements in imaging systems and user interfaces. He holds three patents that showcase his innovative contributions to technology. His work primarily revolves around enhancing the functionality and user experience of devices through advanced imaging and audio processing techniques.

Latest Patents

One of Brian's latest patents is for a system that enables built-in calibration of time-of-flight depth imaging systems. This image processing system utilizes the placement of the imaging sensor and the light source for on-the-fly calibration. The calibration process is crucial as it affects the signal received by a pixel based on the distance to a selected object. For instance, obstructions can block the light emitter, and as these obstructions are positioned further away, the signal level increases due to the light rays bouncing off the obstruction and being received by the imaging sensor. The system includes a light source that emits light, an image sensor that collects incoming signals, and a processor that determines distance measurements and calibrates the system accordingly.

Another significant patent by Brian is related to multi-modal far field user interfaces and vision-assisted audio processing. Traditional far field devices typically rely solely on audio for user interaction. However, Brian's innovation introduces a vision-based modality that enhances the user interface, making it more intuitive. Users can interact with the device by simply looking at it, rather than repeatedly using a wakeword. Additionally, vision can assist in audio processing, improving the performance of the device by aiding in direction of arrival estimation.
