Patent number: 9797651Abstract: A system for facilitating communication of information between an information source positioned inside a refrigerated environment and a position outside the refrigerated environment comprising a transmitter for transmitting a signal including the information, a planar antenna fixed to a gasket for resonating the transmitted signal, the gasket providing a seal between the refrigerated compartment and a door providing access to the refrigerated compartment, and a receiver for receiving the signal including the information. The information could include information concerning at least one container positioned in a refrigerated environment. The system may utilize a Wi-Fi device, a Bluetooth® device, RFID device, or other devices for transmitting the information.Type: GrantFiled: November 20, 2013Date of Patent: October 24, 2017Assignee: FLUID MANAGEMENT SYSTEMS, INC.Inventor: Somnath Mukherjee

Patent number: 8981793Abstract: An apparatus and method is described for measuring non-invasively level of contents inside an array of containers without setting up any electrodes or attaching sensors around the containers, or inserting of a probe inside. Electromagnetic waves are launched from the bottom of the containers using launchers embedded in a tray the containers rest on. These waves travel through the bulk of the contents inside the container using a mode of propagation similar to dielectric waveguides or optical fibers and set up standing waves due to reflection at the content-air interface. The level inside the container is a function of the complex reflection coefficient (magnitude and phase) at the launcher input and can be thus determined by measuring the complex reflection coefficient.Type: GrantFiled: April 11, 2011Date of Patent: March 17, 2015Assignee: Fluid Management Systems, IncInventor: Somnath Mukherjee

Patent number: 8062520Abstract: A system for pressurized liquid extraction of solid samples including quick-connect, threadless columns for holding the solid sample is disclosed. A pressurized liquid extraction (PLE) module continuously performs extraction on the solid sample to yield liquid sample. The quick-connect columns include a threadless, cylindrical tube and end cap assemblies, which are structured and arranged to provide a tight interference fit with the inner surface of the annulus of the column portion and with top and bottom cup rings.Type: GrantFiled: August 21, 2007Date of Patent: November 22, 2011Assignee: Fluid Management Systems, Inc.Inventor: Hamid Shirkhan

Patent number: 6783668Abstract: A system for pressurized liquid extraction and purification of solid samples includes a pressurized liquid extraction (PLE) module including a PLE cell, a heating element, a high-pressure source of an extraction solvent, a pressure regulator, and a cooling coil. The PLE module continuously performs high-pressure, high-temperature extraction on the solid sample to yield liquid sample. The liquid sample is concurrently provided to a purification module including one or more columns. The purification module yields a purified liquid sub-sample containing substantially all of a specific trace substance present in the solid sample. The sub-samples are transferred to a concentrator assembly through a collector inlet. The concentrated sub-sample can be used in subsequent analysis to determine the concentration of the trace substance in the original solid sample.Type: GrantFiled: October 9, 2003Date of Patent: August 31, 2004Assignee: Fluid Management Systems, Inc.Inventor: Hamid Shirkhan

Patent number: 6089538Abstract: A valve assembly has a unitary teflon valve housing with six peripheral facets. A recessed area on the surface of each facet forms a valve seat. Pairs of fluid channels formed in the housing each terminate at openings at a central, planar area of a corresponding valve seat. A pair of rigid tubes are disposed in the openings at each valve seat, each tube forming a fluid-tight seal with periphery of the corresponding opening. The tubes extend slightly beyond the surface of the housing by a predetermined clearance. A diaphragm made of a resilient material covers the valve seat. The periphery of the diaphragm is in fluid-tight sealing engagement with the periphery of the valve seat. A central portion of the diaphragm is coupled to a solenoid above the diaphragm. The solenoid moves the diaphragm central portion between a closed position toward the valve seat and an open position away from the valve seat.Type: GrantFiled: December 30, 1998Date of Patent: July 18, 2000Assignee: Fluid Management Systems, Inc.Inventor: Hamid Shirkhan
