  • Publication number: 20210092948
    Abstract: The present invention is based on the discovery of a stable water-in-oil-in-water double emulsion. The double emulsion composition disclosed may contain molecular complex of volatile compounds for example 1-methylcyclopropene (1-MCP). In addition, the double emulsion composition disclosed can provide prolong or controlled release of the volatile compounds.

  • Patent number: 10869473
    Abstract: Provided are systems and methods for solvent-free delivery of volatile compounds, where an energy source is used to release the volatile compounds. The systems and methods provided herein have at least one advantage of (1) no solvent (for example water) is required; (2) immediate release of volatile compounds (for example 1-MCP can be released from HAIP within milliseconds or seconds instead of minutes or hours of the existing method using water); and/or (3) instantly starting and stopping the delivery of the volatile compound.

  • Patent number: 10555278
    Abstract: The invention provides a method for allocating communication resources in a communication network that comprises a number of different devices and utilizes different technologies. Information is collected of the number of devices of the network. The collected information is transformed from their formats to a common format. The common format makes it possible to handle efficiently all information. Current resources of the communication network and current use of the resources are determined utilizing the collected information in the common format. Alternative ways to use the resources are investigated instead of the current use, and a suggestion(s) is made to use at least one alternative way in case it is more efficient than the current use.
