  • Patent number: 10604466
    Abstract: The present invention provides a method for preparing a resveratrol compound, and belongs to the technical field of organic synthesis. In the present invention, first alkoxy-substituted benzyl halide, alkoxy-substituted benzaldehyde and a metal catalyst are subjected to oxidative addition and reduction elimination reactions to obtain alkoxy-substituted diphenylethanone; and then the alkoxy-substituted diphenylethanone and a metal catalyst are subjected to reduction, trans elimination and selective debenzylation reactions under a hydrogen atmosphere to obtain the resveratrol compound. In the preparation method of the present invention, the hydrogenation reduction, trans elimination and selective debenzylation reactions can be achieved just by a one-pot process, where the reaction directly obtains a trans olefin, thereby avoiding the formation of a isomer; and also the reaction selectively catalyzes debenzylation to eliminate Lewis acids from the source, and has the advantage of a high yield.

  • Patent number: 10578341
    Abstract: A dual-cavity method and device for collecting and storing solar energy with metal oxide particles. Solar radiation irradiates into a light receiving cavity of a dual-cavity, heat-collecting reactor to heat a separating plate and preheat metal oxide particles. The preheated metal oxide particles then enter a reacting cavity. As temperature increases, the metal oxide particles reduce to release oxygen, which discharges through a gas outlet. Reduced metal oxide particles discharge through a particle outlet into a particle storage tank, and then into an oxidation heat exchanger to react with the discharged oxygen discharged to release and transfer stored chemical energy to a medium to be heated. The oxidized metal oxide particles are conveyed into a storage tank, and again enter into a particle inlet of the light receiving cavity. Ambient air controls the gas flow rate in the reactor and the reacting rate in exchanger.

  • Patent number: 10542211
    Abstract: A method is used to evaluate a camera-related subsystem in a digital network, e.g., aboard a vehicle or fleet, by receiving, via a camera diagnostic module (CDM), sensor reports from the subsystem and possibly from a door sensor, rain/weather sensor, or other sensor. The CDM includes data tables corresponding to subsystem-specific fault modes. The method includes evaluating performance of the camera-related subsystem by comparing potential fault indicators in the received sensor reports to one of the data tables, and determining a pattern of fault indicators in the reports. The pattern is indicative of a health characteristic of the camera-related subsystem. A control action is executed with respect to the digital network in response to the health characteristic, including recording a diagnostic or prognostic code indicative of the health characteristic.
