Title: Brian Carey and His Patent for 3D Sensing Laser Drivers

Introduction

Brian Carey is an inventor based in Sunnyvale, California. His patent work includes an on-chip pulse-generation system designed for vertical-cavity surface-emitting laser (VCSEL) drivers used in 3D sensing.

Latest Patents

Carey is associated with 1 patent, titled “Layered Pulse Generation for Laser Driver Application in 3D Sensing.” The invention combines a low-speed pulse generator, a high-speed pulse generator, and a selector on the same chip as the VCSEL driver. Integrating these components can reduce system power consumption and complexity while supporting higher pulse-train frequencies than known systems.

The high-speed generator produces pulses with greater speed and resolution than the low-speed generator. It uses multiple phase-shifted clock outputs, synthesized into a single pulse waveform that can support a range of frequencies, duty cycles, and pulse counts.
