Patent number: 10416107Abstract: Systems and methods can be used for correcting for the presence of voids in a fluid when measuring the conductivity thereof. The conductivity of a fluid can be measured using a conductivity sensor. Capacitance electrodes can be used to measure the capacitance of the fluid. The measured capacitance affected by the fluid can be used in combination with the measured conductivity to determine a corrected conductivity value that compensates for possible voids in the fluid. Other parameters, such as the makeup or temperature of the fluid can be used in determining the corrected conductivity measurement. Some such systems include an annular housing and can be inserted or integrated into fluid flow systems so that fluid to be analyzed flows through an aperture defined by the annular housing.Type: GrantFiled: August 19, 2016Date of Patent: September 17, 2019Assignee: Ecolab USA Inc.Inventors: Martin Ray Godfrey, Eugene Tokhtuev, Joseph Erickson

Patent number: 9002523Abstract: An HVAC controller that monitors the performance of an HVAC system during its operating by comparing a monitored parameter value (e.g. delta T) to a pre-determined limit stored in the HVAC controller memory in order to determine if a performance limit has been violated. In some cases, the HVAC controller may display on a display of the HVAC controller a user alert for at least some of the detected violations. In some instances, the HVAC controller may display or otherwise provide a user alert only after a pre-determined number of performance violations are detected by the HVAC controller. Alternatively, or in addition, the HVAC controller may accept one or more conditions that indicate when a user alert for a detected violation is not to be displayed on the display of the HVAC controller.Type: GrantFiled: December 14, 2011Date of Patent: April 7, 2015Assignee: Honeywell International Inc.Inventors: Peter Joseph Erickson, Cary Leen, Stan Zywicki, Eric Barton, David Schultz, Mohammad Aljabari

Patent number: 8538586Abstract: The present disclosure provides a method for operating a utility-powered HVAC system for conditioning inside air of a building. In an illustrative but non-limiting example, a nominal schedule is maintained by a local HVAC controller, where the nominal schedule has a number of days and one or more time periods for each of at least some of the days. The nominal schedule also has at least one setpoint associated with each of the time periods. The local HVAC controller is configured to accept manual input from a user via a user interface. The manual input may include accepting entry of a utility pricing schedule that corresponds to scheduled price changes of a utility. The utility pricing schedule may include at least one enhanced pricing time period. Entry of at least one utility price level setpoint may also be accepted to correspond to each of the enhanced pricing time periods.Type: GrantFiled: January 22, 2010Date of Patent: September 17, 2013Assignee: Honeywell International Inc.Inventors: John Amundson, Jeffrey Boll, Peter Joseph Erickson, Michael Lunacek, Patrick C.

Patent number: 8076155Abstract: A use composition monitor determines the concentration of peracid and/or peroxide in a use composition using a kinetic assay procedure. A sample mixture containing a sample of the use composition, a diluent and at least one reagent is prepared and analyzed using, for example, an optical detector. Response data obtained by the detector is indicative of the optical absorbance of the sample mixture as a function of time. A processor analyzes the response data to determine a corresponding best fit linear relationship. Depending upon an expected concentration range, the initial absorbance and/or the slope of the best fit equation are used to calculate the concentrations of the peracid and peroxide in the use composition.Type: GrantFiled: February 12, 2009Date of Patent: December 13, 2011Assignee: Ecolab USA Inc.Inventors: Eugene Tokhtuev, Christopher Owen, Paul R.

Patent number: 7924424Abstract: 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 and detectors detect transmitted light at a plurality of wavelengths. The output of each detector and combinations of outputs of multiple detectors are associated with at least one out-of-product threshold. In addition, a color ratio is established. A controller compares the detector outputs and combination outputs with the associated out-of-product threshold(s). If any of the thresholds are satisfied, the controller compares the color ratio with an associated out-of-product threshold to verify an out-of-product event has occurred and reduce errors due to batch-to-batch variation of the product. The sensor is able to determine presence or absence of a variety of products having different color, transparency or turbidity.Type: GrantFiled: April 23, 2009Date of Patent: April 12, 2011Assignee: Ecolab USA Inc.Inventors: Joseph Erickson, Eugene Tokhtuev, Christopher Owen

Publication number: 20080030712Abstract: 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: ApplicationFiled: May 31, 2007Publication date: February 7, 2008Applicant: Ecolab Inc.Inventors: Eugene Tokhtuev, Christopher Owen, Viktor Slobodyan, Anatoly Skirda, Paul Schilling, Anna Pilipchenko, Paul Kraus, Katherine Sanville, Joseph Erickson

Publication number: 20050175024Abstract: A retry algorithm determines the maximum number of transmissions and retransmissions that may be attempted for the frame in the head of a transmit queue or transmit buffer that needs to be transmitted across a communications link. The algorithm attempts to achieve a constant delay for each packet in frame by taking into account the number of frames residing in the transmit queue, the number of transmit opportunities elapsed between the arrivals of two successive frames in the transmit queue s, as well as the buffering capabilities of both the transmitting and receiving sides. The transmission and retransmission control technique provides for a way of managing the TX and RX buffers with a size that is suitable for the application being used and the underlying transport network. The number of retries is adapted to incoming and outgoing data rate changes in order to provide a fixed delay wireless link transport and maximize effective channel utilization.Type: ApplicationFiled: July 14, 2004Publication date: August 11, 2005Applicant: Texas Instruments IncorporatedInventors: Jin-Meng Ho, Joseph Erickson, Horng-Ming Tai
