  • Maximizing power production at low sunlight by solar power mini-inverters
    Patent number: 9331489
    Abstract: A method and apparatus is disclosed for maximizing power production for solar power systems when there is low sunlight during sunrise, sunset, clouding, partial shading, and other low irradiance conditions. A multiple-channel solar power Mini-Inverter can work in the low power mode when there is low sunlight, take power from one solar panel to supply DC power to its internal electronic circuits, and also invert the DC power from the remaining connected solar panels to single-phase or three-phase AC power feeding to the electrical grid or powering AC loads. This invention can significantly reduce the required startup and shutdown irradiance and DC power for the solar power inverter, avoid undesirable shutdowns due to partial shading, and allow the inverter to run in power generation mode for a few more hours each day.

  • Smart and scalable lunar power inverters
    Patent number: 9172270
    Abstract: A method and apparatus is disclosed for solar power generation when irradiance is low and unstable due to sunrise, sunset, clouding, partial shading, warped solar module surfaces, moving solar modules, and other low or varying irradiance conditions. A multi-channel solar power inverter connected to multiple solar modules can work in a “Lunar Power Mode”, inverting DC power induced from the sky, street lights, or surrounding environment to AC power by using a unique rotating power pulling technology. This allows the inverter to dynamically adapt to irradiance variations and generate AC power under complex irradiance conditions. A UPS (uninterruptible power supply) works with a DC power supply to provide DC power to the internal electronic circuits of the inverter allowing it to run in normal power, low power, or lunar power modes.

  • Digital microfluidic platform for actuating and heating individual liquid droplets
    Patent number: 8980075
    Abstract: A digital microfluidic platform utilizes dual active matrix circuitry to actuate and heat liquid droplets on a biochip. Liquid droplets are introduced into a droplet handling area of the biochip where they can be actuated by electrodes residing in pixels of an actuating active matrix array according to the electrowetting on dielectric phenomenon and heated by heating elements residing in pixels of a heating active matrix array. Pixels of the actuating active matrix array and the heating active matrix array are independently addressable such that droplets in the droplet handling area can be selectively heated and actuated according to their location. The actuating active matrix array and heating active matrix array can be formed on the same or different substrates with the droplet handling area disposed above or between the substrates.
