  • Organic light emitting devices
    Patent number: 9871219
    Abstract: The present invention provides an emissive region in organic light emitting devices having a combined emission from at least two emissive materials, a fluorescent blue emissive material and a phosphorescent emissive material.

  • COST CONTROL OF WASTEWATER TREATMENT BASED ON REGULATORY PERIOD
    Publication number: 20170313606
    Abstract: Techniques for controlled aeration (140) of wastewater (190) include determining a first aeration intensity for a first aeration interval and a different second aeration intensity for a second aeration interval (225) based on a current energy price (215), a predicted energy price (221), and a regulatory surveillance period (201) during which a regulated critical parameter is monitored for regulatory compliance. Wastewater is aerated at the first aeration intensity for the first aeration interval; and at the second aeration intensity for the second aeration interval. The first aeration interval is short compared to the regulatory surveillance period, the second aeration interval is short compared to the regulatory surveillance period and does not overlap the first aeration interval, and the first aeration intensity is less than the second aeration intensity.
