Publication number: 20230391571Abstract: A machine direction (MD) position profile measurement of a moving sheet records the MD position of each of the cross direction (CD) measurements. A sheet monitoring system includes means for measuring the MD speed of the sheet of material; means for associating measured MD speed with time to generate time-associated MD speeds; means for recording the time-associated MD speeds; a first scanning sensor for measuring a first characteristic of the sheet material wherein the first scanning sensor is located at a first position along the MD and the first scanner sensor traverses back and forth along a CD; and means for associating first characteristic measurements with time to generate time-associated first characteristic measurements. Single and multiple scanning sensors can be employed. For multiple scanner systems where the scanners are synchronized, the technique enables recreation of the real zig-zag measurement path and same spot measurements.Type: ApplicationFiled: April 4, 2023Publication date: December 7, 2023Inventors: Sudhir Thalore, Gertjan Hofman, Ian Baron, Michael Hughes

Patent number: 11740356Abstract: A dual-optical displacement sensor system includes a scanner including a first and second scanner head including optical displacement sensors providing a first and second beam having a first optical axis (OA) and a second OA. A computing device or programmed circuit is coupled to receive time versus position data from measurements involving alignment target(s) including at least one knife edge pair including a first and second knife edge oriented in a first plane of the alignment target that is essentially perpendicular to the OAs positioned between the scanner heads for interacting with the beams, and implement at least one equation to analyze the data for determining a degree of alignment of the first and second OA. Using the degree of alignment, an algorithm is for automatic alignment of the OAs or assist instructions for a user alignment of the OAs that provides guiding steps for the user for the alignment.Type: GrantFiled: April 13, 2021Date of Patent: August 29, 2023Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Michael Kon Yew Hughes, Sudhir Thalore, Ian Charles Baron, Mayank Kalra, Tal Katz

Publication number: 20230253542Abstract: Fiducial markers (reference marks and associated tracing codes) are applied to sheet materials such as electrodes, paper, plastics, and fabrics and serve as reference points along the machine direction. As the sheet advances, tracing codes are recorded to create a database of tracing codes and as a physical property of the sheet of material is measured a measurement profile is recorded wherein measurements of the physical property are synchronized with the tracing codes from the database so that different portions of the measurement profile are associated with one or more accompanying tracing codes. Customers can match measurements made during production to finished products such as electrochemical batteries so that defects found at a later stage of production can be traced to the source measurements to achieved improved quality assurance. The reference marks facilitate alignment among measurements made by different scanners especially on discontinuous batch processes that require resetting and rethreading.Type: ApplicationFiled: February 7, 2022Publication date: August 10, 2023Inventors: Michael Hughes, Sudhir Thalore

Patent number: 10634542Abstract: A method includes generating first and second timing signals for a level sensor, where the timing signals have a timing difference. The method also includes determining whether the level sensor is able to generate the timing signals so that the timing difference obtains a target value while a control value in a control loop of the level sensor is within defined margins. The method further includes, in response to determining that the level sensor is not able to generate the timing signals so that the timing difference obtains the target value while the control value is within the defined margins, modifying the target value. In addition, the method includes determining whether the level sensor is able to generate the timing signals so that the timing difference obtains the modified target value while the control value is within the defined margins.Type: GrantFiled: May 11, 2017Date of Patent: April 28, 2020Assignee: Honeywell International Inc.Inventors: Masood Karimian-Sichany, Cristian Andronic, Sudhir Thalore, Michael Conroy

Patent number: 10088305Abstract: A scanning measurement system includes independently driven, self-aligning, dual-sided heads. The system is configured to perform a method that includes receiving information associated with a discrepancy in a desired cross direction alignment of a first sensor head and a second sensor head that are disposed on opposite sides of a web of material and that are configured to move in a cross direction relative to the web. The method also includes adjusting a velocity of at least one of the sensor heads based on the received information to improve the cross direction alignment of the first sensor head and the second sensor head.Type: GrantFiled: August 27, 2014Date of Patent: October 2, 2018Assignee: Honeywell LimitedInventors: Ronald E.

Patent number: 9264162Abstract: A method includes wirelessly transmitting one or more messages to a sensor assembly in order to synchronize a clock of the sensor assembly. The method also includes wirelessly receiving multiple sensor measurements of a characteristic of a web of material from the sensor assembly. The method further includes receiving timestamps and position data associated with the sensor measurements. In addition, the method includes correlating the sensor measurements, timestamps, and position data. The sensor measurements from the sensor assembly could be timestamped, and the position data could include timestamped position data. The timestamped position data could be received from a source other than the sensor assembly. The method can further include generating a cross direction profile of the web of material using the sensor measurements, timestamps, and positions.Type: GrantFiled: May 23, 2013Date of Patent: February 16, 2016Assignee: Honeywell LimitedInventors: Gertjan Hofman, Sudhir Thalore

Patent number: 7683796Abstract: An open-wire detection system and method includes a current transmitter that can be connected to one or more wires, wherein the current transmitter provides a minimum current and/or a current that is greater than the minimum current. An anti-aliasing filter is connected to an analog-to-digital converter, such that the anti-aliasing filter receives the minimum current provided by the current transmitter and provides an output signal to the analog-to-digital converter. A noise filter is generally connected to an open-wire threshold detector, wherein the noise filter and the open-wire threshold detector permit detection of input levels below the minimum current provided by the current transmitter. An output from the open-wire threshold detector can be sampled multiple times at intervals that correlate with a frequency of a plurality of digital signals to produce sampled data, such that if the sampled data is below the minimum current, one or more of the wires (e.g.Type: GrantFiled: October 4, 2006Date of Patent: March 23, 2010Assignee: Honeywell International Inc.Inventors: Benjamin J.
