Latest Patents

One of his latest patents is for a digital pulse width modulation power supply with pico second resolution. This innovative laser system includes a laser generation element and a pulse width modulated (PWM) signal generator. The PWM signal generator uses a clock to generate a control signal with a specific period based on the clock frequency. It also features a switch mode power supply that provides power to the laser generation element based on the control signal. Additionally, the system includes a signal modification circuit that selectively delays the rising edge of each control signal period, effectively reducing the pulse width by a quantity smaller than the minimum increment amount based on the clock frequency.

Another significant patent addresses circuit limiting cascade failure of a series of laser diodes. This laser diode control system is designed to prevent cascade failure within a series of laser diodes coupled to an output filter of a switch-mode power supply. The system includes a protection circuit with a post regulator circuit and an inductor, which work together to regulate voltage and prevent current spikes in the event of a failure within the laser diode series.
