  • Patent number: 11968268
    Abstract: An audio session management method may involve: determining, by an audio session manager, one or more first media engine capabilities of a first media engine of a first smart audio device, the first media engine being configured for managing one or more audio media streams received by the first smart audio device and for performing first smart audio device signal processing for the one or more audio media streams according to a first media engine sample clock; receiving, by the audio session manager and via a first application communication link, first application control signals from the first application; and controlling the first smart audio device according to the first media engine capabilities, by the audio session manager, via first audio session management control signals transmitted to the first smart audio device via a first smart audio device communication link and without reference to the first media engine sample clock.

  • Patent number: 10902419
    Abstract: Systems and methods for a blockchain-based system for efficient storage and retrieval of disparate supply-side transaction information. An example embodiment includes features to receive a transaction from a provider system; aggregate the received transaction with a plurality of other transactions, wherein each transaction is encrypted; generate one or more hashes associated with the aggregated transactions, and broadcast the generated hashes onto a blockchain of a blockchain network; store the encrypted transactions and generated hashes, wherein the computer system is configured to respond to a search request received from a user, and wherein the computer system is further configured to validate stored transactions which are responsive to the search request via comparison to the generated hashes on the blockchain.

  • Patent number: 9957444
    Abstract: An apparatus for pyrolyzing a carbonaceous material and producing char and volatiles includes a vessel having an inlet for the carbonaceous material, an outlet for the char and the volatiles, and a first pathway therebetween. The vessel has wall portions with interior surfaces that define the first pathway. Further, the vessel has a heat exchange medium inlet, outlet and a second pathway therebetween. The first and second pathways are in heat exchange proximity to each other and the second pathway is defined by interior surfaces of the, or other, wall interior portions of the vessel. At least some of the interior wall portions of the vessel project into an interior space of the vessel such that at least one of the first and second pathways is non-linear.

  • Patent number: 9828247
    Abstract: The present disclosure provides a process for cleaning raw product gas. The process includes contacting the raw product gas with a flow of catalyst to reform organic contaminants and inorganic contaminants in the raw product gas and to remove particulates. Further, the process includes cooling the resulting product gas via heat exchange with a heat exchange medium in the presence of char or a solid adsorbent medium to condense remaining organic contaminants and inorganic contaminants on the char or solid adsorbent medium and to filter out fine particulates.

  • Publication number: 20150232764
    Abstract: A method of hydrotreatment is provided. The method includes providing a material that is suitable for undergoing hydrotreatment; mixing the material with a hydrogenation agent to form a feed stream; and heating the feed stream to break chemical bonds of the material in the presence of a catalyst. The feed stream is heated to at least a temperature at which the catalyst can provide activated hydrogen to react with the broken bonds within the material so as to minimize coke formed from the material. A system for conducting the method is also provided.
