Latest Patents

One of Raymond Liou's latest patents is titled "Integrated LIDAR Illumination Power Control." This patent describes methods and systems for performing three-dimensional LIDAR measurements using an integrated LIDAR measurement device. In this innovation, a Gallium Nitride (GaN) based illumination driver integrated circuit (IC), an illumination source, and a return signal receiver IC are mounted on a common substrate. The illumination driver IC provides a pulse of electrical power to the illumination source in response to a pulse trigger signal received from the return signal receiver IC. Additionally, the GaN based illumination driver IC controls the amplitude, ramp rate, and duration of the pulse of electrical power based on command signals communicated from the return signal receiver IC. Furthermore, this innovation reduces the amount of electrical power consumed by the illumination driver IC during periods when it is not providing electrical power to the illumination source.

Another notable patent is the "Multi-Channel LIDAR Illumination Driver." This patent details LIDAR measurement systems that utilize a multiple channel, GaN based illumination driver IC. In this system, the multiple channel IC selectively couples each illumination source associated with each measurement channel to a source of electrical power to generate a measurement pulse of illumination light. Each pulse trigger signal associated with each measurement channel is received on a separate node of the IC, and additional control signals are communicated to all measurement channels. The multiple channel IC also includes a power regulation module that supplies regulated voltage to various elements of each measurement channel only when any pulse trigger signal is in a state that triggers the firing of an illumination pulse.
