  • Publication number: 20240176960
    Abstract: Techniques for transcribing and/or summarizing multimedia collaboration sessions are discussed herein. For example, users can communicate within a teleconferencing meeting associated with a channel. In some examples, a first machine learning model may be configured to receive audio-visual data and user interaction data (e.g., selected emojis, detected gestures, messages or text input by a user, a thread of messages, etc.) and output a teleconferencing meeting summary. In some examples, the teleconferencing meeting summary can include one or more highlights, action items, and/or artificial intelligence (AI) notes generated using a machine learning model(s).

  • Patent number: 8776928
    Abstract: The present invention affords a regenerative electric drive refrigerated unit for a conveyance vessel, thereby providing temperature cooling in a compartment of the conveyance vessel. An electricity generator powers a compressor unit in the refrigeration unit. The electricity generator is powered by a drive mechanism obtaining its energy from the motion of the conveyance vessel such that when the invention is employed, a diesel engine that normally powers the compressor unit in the refrigeration unit is disabled and stops running, thereby saving energy and reducing air pollution otherwise generated by the burning of fossil fuels when the diesel engine is running.

  • Patent number: 5250226
    Abstract: Conductive polymer compositions which exhibit PTC behavior comprising a first polymeric component which may be crystalline, a second component, and a particulate conductive filler. The second component may comprise either a polymer which exhibits side chain crystallization or a crystalline material which has a sharp melting point and has poor physical properties at room temperature and/or exhibits no melt strength at elevated temperatures. The compositions are particularly useful in electrical devices which exhibit "square" resistance vs. temperature characteristics.

  • Patent number: 5057345
    Abstract: A polymer blend comprises (A) a fluorinated ethylene-propylene copolymer and (B) a fluoroelastomer. The fluoroelastomer comprises a block copolymer comprising at least one elastomeric segment comprising tetrafluoroethylene, vinylidene fluoride, and hexafluropropylene repeat units in a mole ratio 45-90:5-50:0-35 and at least one nonelastomeric segment comprising tetrafluoroethylene and ethylene repeat units. The weight per cent of copolymer (A) relative to the combined weights of copolymer (A) and fluroelastomer (B) is between about 70% and about 97% or between about 3% and about 30%.
