Title: Francy L. Sinatra and a Binocular Near-Eye Display Invention.

Introduction

Francy L. Sinatra is an inventor based in Redmond, Washington, whose work includes technology for mixed-reality displays. She is associated with Microsoft Technology Licensing, LLC, and is credited with 1 patent.

Latest Patents

Sinatra is named on the patent “Binocular Near-Eye Display with Display Alignment Tracker.” The invention describes a mixed-reality, head-mounted display system that monitors virtual-image pixels in binocular waveguide displays. Its alignment tracker can provide adjustments to the display engine to help reduce binocular and color misalignment caused by thermal expansion, mechanical shock, or vibration.

The system uses surface-relief gratings on waveguide combiner plates. These gratings guide separate display colors, directing virtual-image light from a projector-based display engine while also supporting near-eye viewing and alignment tracking.

Career Highlights

The patent reflects work on improving the alignment and stability of visual content in head-mounted displays. By addressing potential shifts in displayed images during device use, the technology is designed to support a more consistent mixed-reality viewing experience.

Collaborations

Sinatra’s listed coworkers include Tapani Matias Alasaarela and Moran Chen. The patent is associated with Microsoft Technology Licensing, LLC.

Conclusion

Francy L. Sinatra’s patented display-alignment technology addresses practical challenges in binocular mixed-reality systems and contributes to more reliable near-eye display performance.
