The gateway comprises a processor, a network interface, a housing configured to be removably secured onto the NDT/NDI instrument, an interconnect configured to be communicatively coupled with and to carry data to or from the NDT/NDI instrument, and memory storing computer readable code which, when executed on the processor, causes the processor to communicate data with an external network over the network interface. The data includes inspection data which can be any one of the following: ultrasonic scans of A, B, C or S, eddy current strip charts.

Converting a sound to a sound signature and then interpreting the signature based on a machine learning analytical approach. Generally, “interpreting” means quantifying and classifying. A system for identifying statuses of one or more target objects may comprise a device for observing sounds comprising a sound detector, a housing affixing the sound detector on, or in the vicinity of a target object, a processor, a power supply, and a device interface. The system may further comprise a data transmitter, a remote server for receiving data from one or more devices for observing sound of a target object and/or the surrounding environment, a plurality of server-side applications applying analytical operations to the data, and a plurality of end-user devices for accessing the data through a plurality of user interfaces. The status identification system can be used to detect statuses and events of target objects.

A method for automatic diagnosis of a mechanical system of a group of mechanical systems sharing mechanical characteristics includes obtaining data relating to a vibration. The vibration-related data is acquired by a portable communications device configured to communicate with a remote processor. The processor automatically diagnoses the mechanical system by applying a relationship to the obtained vibration-related data. The relationship is based on sets of vibration-related data previously obtained from the mechanical systems. Each set of vibration-related data relates to vibrations of a mechanical system. The relationship is further based on sets of operation data previously obtained for mechanical systems of the group. Each set of operation data indicates a previous state of operation of a mechanical system. Each of the previous states of operation is associated with at least one of the previously obtained sets of vibration-related data.

Disclosed are an online monitoring system for a crack on a hoist spindle and an operation method thereof. The system comprises: a rope power part, a crack detection part, a wireless transmission part, and a computer. The rope power part comprises two traction ropes, two guide wheels, two stepper motors, and two stepper motor drivers. The crack detection part comprises a spiral tube guide rail, a sliding body, and an ultrasonic generator. The wireless transmission part comprises three zigbee wireless sensing modules. The zigbee wireless sensing modules receive instructions from the computer and transmit the instructions to the stepper motor drivers to control the motors to rotate. The stepper motors drive the guide wheels to rotate to realize the winding of the ropes, so as to pull the sliding body to slide on the spiral tube guide rail. The ultrasonic generator clamped on the sliding body monitors the rotating spindle along the spiral tube guide rail. The zigbee wireless sensing modules transmit the detected data to the computer in real time. The present invention can effectively monitor a hoist spindle in time before a failure occurs, thereby avoiding safety accidents.

Systems and methods are presented for a swallowable pH sensor made entirely of edible and digestible materials. A substrate is provided and an electrical circuit pattern is printed on a top surface of the substrate. The electrical circuit pattern includes a plurality of interdigitated electrodes and an antenna portion. The substrate is rolled into a cylindrical form such that the interdigitated electrodes are positioned on an outermost layer of the rolled substrate. The rolling of the substrate also causes the antenna portion of the electrical circuit pattern to form into a coil shape.

Non-limiting examples of the present disclosure describe a non-destructive evaluation (NDE) application/service that is configured for NDE of a wooden specimen. The NDE application/service provides a user-friendly graphical user interface that enables inspectors to manage each phase of NDE of a wooden specimen through one or more computing devices. An exemplary NDE application/service is configured to analyze captured acoustic signal data (e.g., ultrasonic signal data) and transform that captured signal data into feature information that is used to more accurately assess the structural integrity of a wooden specimen. For instance, execution of a programmed NDE application/service employs a trained artificial intelligence (AI) classifier that evaluates waveform propagation (e.g., TOF and energy attenuation) through a wooden specimen to classify a condition and a quality the wooden specimen. An NDE report may be generated that provides an inspector with an assessment of the wooden specimen and/or a network of wooden specimen.

An assembly and method for detecting cross bores and the location of underground pipe system assets includes an acoustic generator placed within an interior of the sewer system and an acoustic receiver placed within proximity of the lateral(s) of the pipe system. The acoustic generator generates an acoustic signal to transmit through the interior of a sewer pipe of the sewer system. A controller detects, in response to the acoustic receiver hearing the acoustic signal, a location of the underground pipe.
