  • Patent number: 11063555
    Abstract: The method of forecasting for solar-based power systems (10) recognizes that no single solar irradiance forecasting model provides the best forecasting prediction for every current weather trend at every time of the year. Instead, the method trains a classifier to select the best solar irradiance forecasting model for prevailing conditions through a machine learning approach. The resulting solar irradiance forecast predictions are then used to allocate the solar-based power systems (10) resources and modify demand when necessary in order to maintain a substantially constant voltage supply in the system (10).

  • Patent number: 10927214
    Abstract: The method of making a pyrrolo bisthiazole homopolymer starts with dissolving a dibrominated pyrrolo[3,2-d:4,5-d?]bisthiazole monomer having the formula: where R is an alkyl group, in anhydrous tetrahydrofuran (THF). Then, the solvated monomer is treated with 1 equivalent of a Turbo-Grignard reagent complex having the formula iPrMgCl.LiCl at 0° C. to form a reaction mixture. The reaction mixture is stirred for 1 hour at room temperature, and after stirring, the reaction mixture is refluxed for 24 hours. A conjugated homopolymer product having the formula: where n is the number of repeating units of pyrrolo[3,2-d:4,5-d?]bisthiazole, is recovered from the reaction mixture. The PBTz-based homopolymers showed broad absorption from 450 to 850 nm in thin film and excellent photochemical and thermal stability, making the polymers suitable for lightweight, low cost plastic electronic devices.

  • Patent number: 10724758
    Abstract: The heat index thermostat is an electronic, programmable thermostat having a microcontroller or microprocessor programmed to regulate the temperature of an enclosed space, such as a room or building. The thermostat has a user interface that permits the user to select a mode of operation and to enter a set temperature, and input terminals for receiving signals from relative humidity, indoor temperature, and other sensors. In a heat index mode of operation, the temperature is regulated by reference to a lookup table based on a heat index equation. The microcontroller uses the table inversely by using the set temperature as the heat index temperature, looking up the room temperature that would result in that heat index temperature given the measured relative humidity in the room. The thermostat then turns the cooling/heating unit on or off until the measured room temperature is equal to the temperature determined from the lookup table.

  • Publication number: 20200108351
    Abstract: The multi-layered membrane (100) for separating oil and water includes a porous top layer (110), a porous bottom layer (130), and a particulate middle layer (120) positioned between the top layer (110) and the bottom layer (130), the middle layer (120) being hydrophobic and adapted for adsorbing oil, such as trace amounts of oil, that may pass through the top layer (110). The top layer (110) and the bottom layer (130) are hydrophilic and oleophobic. While the membrane (100) does not require any external pressure other than the gravitational forces exerted on the oil/water mixture W to drive the filtration of the oil/water mixture W through the membrane (100), the filtration can be driven by a vacuum or other type of external pressure.

  • Publication number: 20200048783
    Abstract: The electrocatalyst for hydrogen evolution reaction includes nanosheets of molybdenum disulfide (MoS2) deposited on a carbon fiber substrate. The catalyst is formed in stepwise fashion by chemical vapor deposition of nanosheets of MoO3 onto the substrate, then reducing the MoO3 to nanosheets of MoO2 using sublimed sulfur, then by reaction of sulfur vapor with the MoO2 to form nanosheets of MoS2 on the carbon fiber substrate. The catalyst is multifaceted, having a large density of edges providing catalytically active sites for the hydrogen evolution reaction. The activity of the catalyst is enhanced by coating the catalyst with spherical fullerenes (nC60).
