Abstract: Methods, apparatus, systems and articles of manufacture are disclosed for power selection. An example method includes, when a first limit switch detects that a first device is in a first position, powering a second device based on a first output of the first limit switch, when a second limit switch detects that the first device is in a second position, powering the second device based on a second output of the second limit switch, and performing the diagnostic task based on at least one of the first output or the second output.

Abstract: A method of controlling a valve can include monitoring electrical power supplied to the valve and/or monitoring pneumatic pressure supplied to the valve. Upon failure of the electrical power and/or pneumatic pressure, the operative position of the valve can be held in its last position and/or moved to a fail-safe position. Whether the valve position is held, or moved to a fail-safe position, can be independent of, or dependent upon, the position of the valve and/or an error in position of the valve.

Abstract: Systems and methods for identifying similar three-dimensional (3D) representations of an object. The method includes receiving at an interface a target 3D model and at least one candidate 3D model, executing at least one feature identification procedure to identify a feature of the target 3D model, generating a target feature tensor based on the identified feature of the target 3D model, and executing the at least one feature identification procedure on the candidate 3D model. The method further includes generating a candidate feature tensor based on the identified feature of the candidate 3D model, executing at least one comparison function to compare the target feature tensor and the candidate feature tensor, generating a feature comparison tensor based on the execution of the at least one comparison function, and identifying a degree of similarity between target 3D model and the candidate 3D model based on the feature comparison tensor.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed for power selection, including evaluating a first power source to determine if the first power source is available, evaluating a second power source to determine if the second power source is available, upon determining that a power source of the first and second power sources is available, selecting the power source, providing power from the selected power source to a sensor, and performing the diagnostic task based on an input from the sensor.

Abstract: Methods and systems obtain manufacturer data from a device being evaluated. The manufacturer data includes a system description, a system object identification, and a device-type description. The system description includes a serial number having a format. The system object identification includes a standards manufacturer field established by a standards organization. The methods/systems evaluate the standards manufacturer field to identify the manufacturer, and rank multiple system object identifications based on the quantity of data within each system object identification. Additionally, the methods/systems match the format of the serial number to known manufacturer serial number formats. The foregoing allows the methods/systems to determine the original equipment manufacturer (OEM) of the evaluated device based on the manufacturer appearing in the data string, the rank for each system object identification, and the manufacturer appearing in the serial number format match.
