  • Publication number: 20180000345
    Abstract: A patient monitoring system includes at least two wireless sensing devices, each configured to measure a different physiological parameter from a patient and wirelessly transmit a parameter dataset. The system further includes a receiver that receives each parameter dataset, a processor, and a monitoring regulation module executable on the processor to assign one of the at least two wireless sensing devices as a dominant wireless sensing device and at least one of the remaining wireless sensing devices as a subordinate wireless sensing device. The physiological parameter measured by the dominant wireless sensing device is a key parameter and the parameter dataset transmitted by the dominant wireless sensing device is a key parameter dataset. The key parameter dataset from the dominant wireless sensing device is processed to determine a stability indicator. The subordinate wireless sensing device is then operated based on the stability indicator for the key parameter.

  • Publication number: 20170370839
    Abstract: A component treatment processes and treated gas turbine components are disclosed. The gas turbine treatment process includes laser-removing coating from a substrate of a turbine component to form laser-induced plasma, spectroscopically analyzing the laser-induced plasma, and discontinuing the laser-removing in response to the spectroscopic analyzing. The treated gas turbine component includes a laser-affected surface, the laser-affected surface having one or both of modified dimensions and modified microstructure due to being exposed to the laser-removing of the coating. The laser-affected surface has a depth corresponding to the laser-removing being discontinued based upon the spectroscopic analyzing of the laser-induced plasma formed from the laser-removing.
