Abstract: In part, the disclosure relates to computer-based methods, and systems suitable for evaluating a subject to determine the appropriate diagnostic tools for assessing coronary arteries. This can include assessing various blood pressure values during a resting state (without inducing hyperemia). These systems and methods can assess a patient and identify coronary dominance on per patient basis. In turn, this assessment can be used to recommend whether a resting index is appropriate or if another index such as FFR or others such be obtained diagnostic metric such as a pressure value-based ratio.

Abstract: A self-contained welding power supply capable of, upon termination of welding operation, automatically setting a control signal for auxiliary power is provided. The power supply comprises an engine, a generator driven by the engine, and an excitation system that controls power output of the generator. The excitation system includes an output controller and a DC controller. The output controller includes circuitry that generates a field voltage control signal to be sent to the DC controller to regulate DC power going to field windings of the generator. Upon termination of the welding operation, the field voltage control signal is automatically set to a value appropriate for the auxiliary system operation.

Abstract: The invention described herein generally pertains to a system and method related to an engine-driven welding device that generate a welding voltage and an auxiliary voltage using a rotor/stator assembly at various frequency settings or revolutions per minute while maintaining outputs for the welding voltage and the auxiliary voltage. A welding device can include a field controller component and/or a controller that is configured to detect a change in a frequency setting or an engine speed. In response to such detection, the field controller component can be configured to adjust an excitation voltage in order to maintain a voltage output used for a welding voltage or an auxiliary power voltage power.

Abstract: The invention described herein generally pertains to a system and method for including a port component to an engine driven welding device. An engine driven welding device includes a motor that is a power source for a welding operation, wherein a first circuit converts a voltage from the power source to a second voltage. A port component utilizes the second voltage as a power source for an external device. Additionally or alternatively, the port component utilizes the second voltage to power a data transfer between the external device and the engine driven welding device.

Abstract: A portable welding cell unit includes a frame structure in which first and second welding stations are disposed. A robot arm is also provided within the frame. The robot arm can pivot between the first and second welding stations such that a work piece can be welded in the first welding station while a work piece is being loaded into or unloaded from the second welding station.
