First Claim
Patent Images
1. A method for monitoring a machine, the method comprising:
- providing an electrical signal for transmission to and into a component of the machine;
monitoring the electrical signal in the component;
comparing at least one characteristic associated with the monitored electrical signal to at least one associated expected value; and
detecting, based at least in part on the comparison, a rub condition or a potential rub condition for the component of the machine.

Abstract
Systems, methods and apparatus for monitoring rub detection in a machine are provided. An alternating current voltage signal may be transmitted or communicated to at least one component of the machine. The transmitted signal may be monitored in the at least one component and at least one characteristic associated with the monitored signal may be compared to an expected value for the at least one characteristic. Based at least in part on the comparison, a rub condition or potential rub condition may be identified between the at least one component and another component of the machine.

17. A method for monitoring a machine, the method comprising:
-
transmitting an alternating current voltage signal to and into at least one component of the machine; monitoring the signal in the at least one component to determine an impedance associated with the signal; and comparing the determined impedance to an expected value for the impedance; and
identifying, based at least in part on the comparison, a rub condition between the at least one component and another component of the machine. - View Dependent Claims (18, 19, 20)
