Abstract
Official abstract text for this publication.
A turbo machine includes a speed probe that is configured to detect a speed of a rotating feature. Engine controls are used by a processor to control operation of the turbo machine. The processor communicates with the speed sensor and receives the speed signal to produce a command signal. A detection module is arranged in parallel with the processor and communicates with the speed probe to receive the speed signal. The detection module compares the speed signal with data to determine whether the speed signal is reliable. In one example, the detection module bypassed the processor and sends a corrective command directly to an engine control device in response to an unreliable speed signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A turbo machine comprising: a rotating feature; a speed probe configured to detect a speed of the rotating feature and produce a speed signal indicative of the speed; engine controls configured to control operation of the turbo machine, the engine controls including a device; a speed module in communication with the speed probe and configured to receive the speed signal and produce a transformed speed signal in response to the speed signal, wherein the…
