Publication number: 20220316933Abstract: The present disclosure relates to wastewater management that provides method and system for monitoring sewer manhole from a remote location. Sewer monitoring system configured in a sewer manhole receives measured values from level sensor and determines accuracy error in the measured values for different conditions. Thereafter, sewer monitoring system resolves the accuracy error in the measured values to obtain accurate measured values by either measuring level of wastewater in the sewer manhole by setting first range limit for the measured values dynamically based on actual depth of sewer manhole, or iteratively measuring level of wastewater in the sewer manhole by setting unique second range limit for the measured values dynamically. Finally, a risk associated with the sewer manhole based on the accurate measured values of the level sensor is determined, for monitoring the sewer manhole from a remote location.Type: ApplicationFiled: November 4, 2021Publication date: October 6, 2022Inventors: Arindam ROY, Vanganuri HARISH KUMAR RAMA SAGAR

Patent number: 10749737Abstract: Disclosed is an interoperability gateway system that provides backup connection between a dispatch center and a Land Mobile Radio (LMR) system in the event the dispatch center is disconnected from the LMR system. In general, this may be accomplished by providing an RF link between the disconnected site and the interoperability gateway via a controller, or interoperability site network interface (ISNI), that is activated when the dispatch center is disconnected from the LMR system. The interoperability gateway provides the backup connection by allocating a control station for each channel available at the disconnected LMR system. When compared to conventional dispatch console backup schemes, the disclosed interoperability gateway system greatly reduces the equipment needed to provide dispatch console backup, thereby decreasing equipment and operation costs, and simplifying operation by providing a solution that is virtually transparent to the dispatcher.Type: GrantFiled: January 30, 2019Date of Patent: August 18, 2020Assignee: E.F.
