Abstract: The subject matter of this specification can be embodied in, among other things, a fluid flow conditioning apparatus that includes a linear fluid conduit having a first tubular body defining a major axis and extending from a conduit inlet to a conduit outlet arranged opposite the conduit inlet, and configured with a predetermined flow geometry to define a linear fluid flow path along the major axis, a fluid inlet non-parallel to the linear fluid flow path, a first fluid flow conditioner configured to receive fluid flow, condition fluid flow, and redirect conditioned fluid flow along the linear fluid flow path along the major axis, a second fluid flow conditioner configured to receive fluid flow from the linear fluid flow path along the major axis, redirect fluid flow away from the linear fluid flow path, and condition fluid flow.

Abstract: The subject matter of this specification can be embodied in, among other things, a method for controlling a turbine engine that includes receiving a predetermined arming threshold signal, receiving a predetermined triggering threshold signal, receiving a periodic signal from a speed sensor, determining a frequency signal based on the periodic signal, the predetermined arming threshold signal, and the predetermined triggering threshold signal, determining a speed value based on the determined frequency signal, and controlling a speed of a turbine based on the determined speed value.

Abstract: The subject matter of this specification can be embodied in, among other things, an identification system includes a first component having a first resistor and a second resistor, a second component having a sensor configured to sense a voltage difference between a first bus and a second bus and a selector signal output port configured to provide a first selector signal and a second selector signal, and a third component having a switching network configured to electrically connect the second bus to the first bus across one or both of the first resistor and the second resistor in response to the first selector signal, and electrically connect the second bus to the first bus across a different one of the first resistor or the second resistor in response to the second selector signal.
