Patent number: 9336585Abstract: A tester and a method that evaluate the condition of a bundle of plurality of tubes are disclosed. Embodiments of the tester obtains an image of a tube-sheet of the bundle; obtaining one or more parameters related to the tube-sheet image. Next one or more feature-detecting methods can be implemented on the tube-sheet image to define tube endings on a grid of the tube-sheet. Further, optimization methods can be implemented on the results and a map with the result can be presented to a user of the tester. Feedback from the user can be utilized to improve the map of the tube sheet.Type: GrantFiled: December 21, 2011Date of Patent: May 10, 2016Assignee: ACOUSTICEYE LTDInventor: Silviu Zilberman

Patent number: 9335299Abstract: Exemplary embodiments of method and system for guiding a tester of a bundle of similar objects are disclosed. The disclosed embodiments may obtain a picture of the bundle of the similar objects. The image may be processed in order to identify the bundle of similar objects to be tested. Then, the system may determine which object of the similar objects to measure and accordingly it may instruct a tester to associate an object-measuring device with the determined object to be measured. Upon receiving a trigger signal issued by the tester, information is collected regarding the test results of the measured object and information on the location of the measured object. Then the process can proceed for additional objects in the bundle.Type: GrantFiled: June 16, 2011Date of Patent: May 10, 2016Assignee: ACOUSTICEYE LTDInventors: Noam Amir, Tal Pechter, Oded Barzelay

Patent number: 9134277Abstract: The internal state of a tube system is detected and monitored by coupling multiple inspection modules to the tube system. Each inspection module injects a signal into the tube system and detects reflections of the signals. The distance between the module and the fault causing a reflection is determined by analyzing the timing between the transmitted signal and detected reflection, along with a known propagation speed of the signals. The location of faults is determined by comparing the distance calculations from two or more inspection modules. Monitoring can be performed over time to identify the development or changes of faults. Monitoring can be done while tube system is active without disrupting the flow of material through the active tube system.Type: GrantFiled: November 17, 2010Date of Patent: September 15, 2015Assignee: ACOUSTICEYE LTDInventors: Noam Amir, Tal Pechter

Publication number: 20150253238Abstract: A tube inspection system that includes a guided-wave-transducer mechanism (GWTM) that is associated with a tube that is being inspected. The GWTM can have one ring with ‘N’ guided-wave transducers (GWTs) distributed thereon, and another ring with ‘M’ guided-wave transducers (GWTs) distributed thereon. A controller excites mechanical waves by the GWTs of the first ring that propagate in the wall of the tube being inspected and along its axis. The ‘M’ GWTs of the second ring obtain received mechanical waves and convert them to electronic signals. The ‘M’ electronic signals are processed to provide a measured signal in which a wanted mode is enhanced.Type: ApplicationFiled: March 8, 2015Publication date: September 10, 2015Applicant: ACOUSTICEYE LTDInventor: Dov Furman

Publication number: 20150211917Abstract: A measurement systems that reduces spurious artifacts in reflected signals by generating and employing an improved maximum length sequence. Accurate acoustic measurements with both high SNR and low spurious artifacts are made possible by generating Wide MLS (WMLS) which modifies a base MLS by replacing each value with a sequence that includes the value and one or more additional values, where typically the replaced values have opposing polarities and, the additional signals have intermediate values. An exemplary intermediate values can be approximately zero value.Type: ApplicationFiled: March 9, 2015Publication date: July 30, 2015Applicant: AcousticEye LtdInventor: Harel Primack

Publication number: 20150122030Abstract: Tube inspections are performed by combining the use of APR technology with GW technology. The reflections measured by both technologies are compared to each other and used to more specifically identify the type and location of a flaw or anomaly that appears in the interior of the tube. Further, embodiments of novel probes to be used in GW technique for inspecting tubes with mechanical waves having bandwidth that is equal to 150 KHz or more are disclosed.Type: ApplicationFiled: June 10, 2013Publication date: May 7, 2015Applicant: ACOUSTICEYE LTDInventors: Noam Amir, Dov Furman, Harel Primack, Silviu Zilberman

Publication number: 20130332091Abstract: A system to measure the internal state of a bundle of tubes by injecting a signal into each tube of the bundle, receiving reflections from the tube due to anomalies within the tube, then analyzing the reflections to determine the type or characteristics about the anomalies. The analyzed information is stored in database to be used for statistical processing. Further, the device can be used in the performance of a cleaning process by conducting an initial assessment of the tubes in a bundle of tubes, comparing the stored data and estimating the number of cleaning cycles that will be required, and re-conducting the evaluation of the state of the tubes after every cleaning cycle or after every few cleaning cycles.Type: ApplicationFiled: August 16, 2013Publication date: December 12, 2013Applicant: ACOUSTICEYE LTDInventors: Noam Amir, Tal Pechter
