Abstract: Systems and methods of using secondary measurements to make a system-based determination are provided. Some methods can include a transceiver device receiving a first signal from at least one system-based device, the transceiver device receiving a second signal from at least one non-system device, and control circuits coupled to the transceiver device making a system-based determination responsive to both the first signal and the second signal.

Abstract: A regional monitoring system in communication with a plurality of locally displaced detectors can implement a fusion of inputs from a variety of additional non-system devices. The monitoring system includes a wireless receiver or transceiver enabling the system to detect local traffic from the non-system devices, such as sensors. Information received from such non-system devices can be combined with information from system detectors to initiate activity on other networks, to energize actuators, or to activate system detectors that normally reside in a low energy inactive state.

The monitoring system includes a wireless receiver, or transceiver, enabling it to detect local traffic from the non-system devices, such as sensors. Information received from such non-system devices can be combined with information from system detectors to initiate activity on other networks, to energize actuators, or to activate system detectors that normally reside in a low energy, inactive, state.

Abstract: A steam turbine rotor includes a plurality of turbine wheels secured to a shaft by an interference shrink fit between each wheel and a corresponding step surface on the shaft. The step surfaces have decreasing radii over a portion of the axial length of the shaft. Each wheel incudes a hub section proximate the shaft and each hub section has a shoulder portion of greater radial dimension than the radially innermost surface of the hub section. A member or finger protrudes from one shoulder and mates with a longitudinal slot on one of the step surfaces of the shaft. Relief grooves are also provided for on the shaft and hub section.
