  • Patent number: 11114862
    Abstract: In one embodiment, a solar cell installation includes several groups of solar cells. Each group of solar cells has a local power point optimizer configured to control power generation of the group. The local power point optimizer may be configured to determine an optimum operating condition for a corresponding group of solar cells. The local power point optimizer may adjust the operating condition of the group to the optimum operating condition by modulating a transistor, such as by pulse width modulation, to electrically connect and disconnect the group from the installation. The local power point optimizer may be used in conjunction with a global maximum power point tracking module.

  • Patent number: 8730479
    Abstract: System, including methods and apparatus, for light detection and signal processing for droplet-based assays. An exemplary system provides a method of detection for droplets. An examination region of a channel may be illuminated with first pulses of light interleaved with second pulses of light as droplets pass through the examination region, the first pulses being spectrally distinct from the second pulses. Data may be collected representing light detected during illumination of the examination region with the first pulses and the second pulses. Each droplet may be illuminated with a beam of light that is narrower than a diameter of the droplets.

  • Patent number: 8299416
    Abstract: The present invention provides a high-speed Quantum Efficiency (QE) measurement device that includes at least one device under test (DUT), at least one conditioned light source with a less than 50 nm bandwidth, where a portion of the conditioned light source is monitored. Delivery optics are provided to direct the conditioned light to the DUT, a controller drives the conditioned light source in a time dependent operation, and at least one reflectance measurement assembly receives a portion of the conditioned light reflected from the DUT. A time-resolved measurement device includes a current measurement device and/or a voltage measurement device disposed to resolve a current and/or voltage generated in the DUT by each conditioned light source, where a sufficiently programmed computer determines and outputs a QE value for each DUT according to an incident intensity of at least one wavelength of from the conditioned light source and the time-resolved measurement.

  • Patent number: 8160113
    Abstract: Output pulses from an optical system having a seed source and an optical amplifier coupled to the seed source may be controlled by controlling a power of a seed signal from the seed source. The seed signal may be varied between a minimum value and a maximum value in a way that the seed signal exhibits one or more pulse bursts. Each pulse burst may contain one or more pulses. During an inter-pulse period between successive pulses within a pulse burst or between successive pulse bursts, the power of the seed signal may be adjusted to an intermediate value that is greater than the minimum value and less than the maximum value. The intermediate value is chosen to control a gain in the optical amplifier such that a pulse or pulse burst that follows the period exhibits a desired behavior.

  • Patent number: 7887766
    Abstract: A well plate and its supporting devices provide capabilities found in larger fermenters, such as controlling the oxygen level, the pH level, and temperature of the contents of the well. The well plate includes a plurality of wells, each of which can be independently controlled. Apertures in the wells, for example, provide access for a gas supply and sensors within each well provide data relating to, e.g., oxygen and/or pH level in the well. A control system controls the gas supply for each well based on the information provided by the sensor within the well. Similarly, temperature control elements, such as a heater or cooler, is placed in thermal contact with the interior of the well, as is a temperature measurement element. A control system can independently control the temperature of the contents of the well based on information provided by the temperature measurement element for that well.
