Patent number: 8395515Abstract: A system and associated processes monitor hand hygiene compliance. The system includes hand hygiene product dispensers positioned within areas of concern (AOC) in a facility in which hand hygiene events are to be monitored. The dispensers detect dispense events initiated at the dispenser and transmit a dispense event signal indicative that a dispense event occurred along with dispenser identification information. The system also includes a plurality of compliance badges, each worn by a different person in the facility. Each compliance badge receives dispense event signals corresponding dispenser identification information associated with dispense events initiated by the wearer of the compliance badge. The badges store dispense event records associated with each dispense event initiated by the wearer and thus keep track of all dispense events initiated by the wearer of the compliance badge.Type: GrantFiled: May 25, 2010Date of Patent: March 12, 2013Assignee: Ecolab USA Inc.Inventors: Eugene Tokhtuev, Christopher J. Owen, Paul S. Schilling, Anatoly Skirda, Viktor Slobodyan, Joseph P. Erickson, Cheryl A. Littau

Patent number: 8373140Abstract: Embodiments provide an optical sensor head and method of making an optical sensor head. In some cases the sensor head can be used as a fluorometric sensor to measure concentrations of substances within a liquid sample of interest. The sensor head includes a light source window and a detector window that transmit light between the sensor head and an analytical area. In some cases the windows include a ball lens positioned within a channel such that the ball lens and the channel create a seal between the interior and exterior of the sensor head.Type: GrantFiled: March 31, 2010Date of Patent: February 12, 2013Assignee: Ecolab USA Inc.Inventors: Eugene Tokhtuev, William M.

Patent number: 8166828Abstract: Fluid flow meters and methods for measuring different aspects of fluid flow with a non-contact sensor are provided. In some cases a fluid flow gear meter is provided with a fluid chamber that is sealed with a cover portion carrying the non-contact sensor. An optional separation member may be located between the cover portion and the chamber to seal the chamber. In some cases the cover portion and/or separation member are configured to transmit visible light to allow viewing of the fluid chamber, through material selection and/or the presence of viewing cavities within the material. The flow meter is optionally configured to prevent or reduce the transmission of ambient environmental radiation into the flow meter to lessen the likelihood that it may adversely affect an optical non-contact sensor used to detect movement of gears within the chamber.Type: GrantFiled: August 6, 2010Date of Patent: May 1, 2012Assignee: Ecolab USA, Inc.Inventors: Anatoly Skirda, Richard Mehus, William M.

Patent number: 8120500Abstract: An acoustic sensor detects presence and/or absence of fluid in a fluid delivery medium. The acoustic sensor detects fluid absence based on the difference of the speed of sound between air and a fluid. For example, the acoustic sensor may detect fluid absence based on a phase shift between acoustic signals transmitted through the fluid delivery medium when fluid is present as compared to acoustic signals transmitted through the fluid delivery medium when fluid is absent, e.g., when air or bubbles are present in the fluid delivery medium.Type: GrantFiled: December 8, 2008Date of Patent: February 21, 2012Assignee: Ecolab Inc.Inventors: Eugene Tokhtuev, Christopher J.

Patent number: 8084756Abstract: An ultraviolet (UV) fluorometric sensor measures a chemical concentration in a sample based on the measured fluorescence of the sample. The sensor includes a controller, at least one UV light source, and at least one UV detector. The sensor emits UV light in a wavelength range of 245-265 nm from the light source through the sample in an analytical area. The UV detector measures the fluorescence emission from the sample. The controller transforms output signals from the UV detector into fluorescence values or optical densities for one or more wavelengths in the wavelength range of 265-340 nm. The controller calculates the chemical concentration of the chemical in the sample based on the measured fluorescence emissions.Type: GrantFiled: July 1, 2011Date of Patent: December 27, 2011Assignee: Ecolab Inc.Inventors: Eugene Tokhtuev, Christopher J.

Patent number: 8069719Abstract: Embodiments of the invention provide devices and methods for measuring fluid volume. Devices according to some embodiments include a chamber, having a pair of gears rotatably mounted therewithin. Fluid flow through the chamber causes rotation of the gears, such that each rotation and/or partial rotation results in a known volume of the fluid passing through the chamber. An optical sensor positioned outside of the chamber, can view the rotating gears through a substantially transparent chamber wall. The optical sensor can view an optical characteristic of one or both of the gears, and based upon this data, fluid volume, flow rate, and/or flow direction can be determined. Devices and methods disclosed herein can provide for improved precision in fluid flow meter measurement. In addition, the devices and methods used herein can be more durable and easier to fabricate than previously known positive displacement flow meters.Type: GrantFiled: February 11, 2009Date of Patent: December 6, 2011Assignee: Ecolab USA Inc.Inventors: Eugene Tokhtuev, Christopher Owen, Anatoly Skirda, Viktor Slobodyan, Richard Mehus

Patent number: 8004683Abstract: An optical detection sensor detects presence or absence of a product within a fluid delivery medium. An emitter directs radiation into the fluid delivery medium. Each of a plurality of detectors detects light within an associated one of a plurality of wavelength ranges transmitted through the fluid delivery medium. The output of each detector is further associated with at least one out-of-product threshold. A controller may further combine detector outputs, such as by multiplication, summation, or other mathematical operation, to produce additional measures of product presence or absence. Each combination output is also associated with at least one out-of-product threshold. The controller compares the output of each detector with the associated out-of-product threshold(s) and compares each combination output with the associated out-of-product threshold(s) to determine presence or absence of product within the fluid delivery medium.Type: GrantFiled: October 8, 2008Date of Patent: August 23, 2011Assignee: Ecolab USA Inc.Inventors: Eugene Tokhtuev, Christopher J.
