Abstract: A device, method, and non-transitory computer readable medium that determine a reliability level for a communication network. A packet delivery ratio (PDR) is determined for a round period of the communication network operating at an adaptive reliability level based on a packet serial number (PSN). The communication network is controlled in a best effort mode, a reliable mode, or a switching mode based on the PDR.

Abstract: Smart elevator systems and methods for controlling an elevator system use sensors that transmit data to a processor in a network system for use in operating an elevator system. The elevator system can include a system connected to a LAN, WAN, intranet, interne, etc. and is capable of exchanging data with and retrieving data therefrom. In the smart elevator systems, there are a number of wireless sensors that detect and transmit information on a number of people requesting elevator transport. The smart elevator system uses that information to select or determine one or more transport paths for one or more elevators to follow and, therefore, can be beneficial in enhancing efficient use of one or more elevators in an elevator system to service persons awaiting elevator service.

Abstract: The ionic liquid for desulfurization of light fuels is 1-methyl-3-pentyl 1H-imidazolium periodate, having the structural formula: The compound is prepared by mixing 1-methyl-3-pentyl 1H-imidazolium tetrafluoroborate with sodium periodate in dichloromethane and water, stirring the mixture for 24 hours, and extracting the compound from the product with dichloromethane. The ionic liquid may be used for the desulfurization of light fuels by bringing the ionic liquid into contact with the crude light petroleum oil at a temperature of about 50° C. with stirring for a period of time sufficient to oxidize the sulfur containing impurities to water soluble sulfones, washing the mixture with water to remove the ionic liquids and water soluble sulfones, and drying the desulfurized light fuel product.
