An indicative signal is generated at the interface when the measured resistance of the selected sensor is outside of a specification of the selected sensor.Type: GrantFiled: November 12, 2014Date of Patent: November 21, 2017Assignee: KIDDE TECHNOLOGIES, INC.Inventor: Robert J.

Patent number: 9823155Abstract: A test plug for insertion into and plugging of an open end of an elbow pipe is provided. The test plug includes a resilient sealing element and set of gripper segments carried on a shaft. The set of gripper segments are movable relative to the shaft between pipe-gripping and pipe-non-gripping positions such that, when the test plug is placed in sealing and gripping engagement relative to an inner diameter wall of an elbow pipe, the set of gripper segments are positioned in eccentric relation to at least one of the sealing element and the shaft.Type: GrantFiled: August 17, 2015Date of Patent: November 21, 2017Assignee: EST Group, Inc.Inventors: Ka'ren Sarkissian, Alex Kotlyar, Danko Kobziar

Patent number: 9823156Abstract: Water leaks in irrigation systems may be detected by analysis of water pump energy consumption data captured from a utility power meter. Unlike existing solutions that use water meters or acoustic sensors, embodiments of the present apparatus and methods described herein detect water leaks based upon the electrical load associated with the water pump(s) in irrigation lines. These methods have the advantage of not requiring any extra hardware at the site of the irrigation system.Type: GrantFiled: October 3, 2014Date of Patent: November 21, 2017Assignee: PowWow Energy, Inc.Inventors: Olivier Jerphagnon, Brad Gaiser

Patent number: 9823157Abstract: An apparatus for close visual inspection of subsea pipelines comprises a housing with a chamber that has an open side. The open side is adapted to be placed in sealing engagement against the pipeline. The chamber is flooded with clear water to improve the visual view. It is also described an apparatus for identification of a plume exiting from a leak The apparatus comprises a housing defining a chamber with a water permeable side that is adapted to face downward during use, and thereby being exposed to the exiting substance. A gas pressurizing device for creates a gas/water interface within the housing. An imaging device arranged above the water surface is adapted to image the water surface and detect id the water surface is being disturbed by the plume.Type: GrantFiled: September 23, 2013Date of Patent: November 21, 2017Assignee: Universitetet i StavangerInventors: Jasper Ahamefula Agbakwuru, Ove Tobias Gudmestad

Patent number: 9823158Abstract: A system for ultrasonic leak detection employs a number of ultrasonic signal generators, each of which include an ultrasonic transducer generating an ultrasonic signal and an audio transducer generating an audio signal in the frequency range of human hearing that is a replica of the ultrasonic waveform. The ultrasonic signal generators are activated and placed at selected locations within the enclosure to be tested. The operator can listen for the audio signal to verify operation and the output waveform type of the ultrasonic signal generators. A mobile ultrasonic leak detector can then be employed outside the enclosure to detect any leakage of the ultrasonic signal through the enclosure wall to identify any leak paths.Type: GrantFiled: January 5, 2015Date of Patent: November 21, 2017Assignee: Radiaulics, Inc.Inventors: Nikolaos I. Komninos, Arthur Ray Hughes
