Abstract: A method of retrofitting a gas turbine wherein the gas turbine comprises a stator and a rotor. The rotor is coaxially aligned with the stator and spaced apart from the stator so as to define a gap therebetween. The method of retrofitting comprises fixedly securing a sealing member to the stator. The sealing member is configured to restrict a flow of a fluid medium in a fluid path across the gap and generate a pressure drop generally transverse to the gap during operation of the gas turbine.

Abstract: A remotely located ultrasound beamformer is serviced from a central service facility via a network in a manner that compensates for defective beamformer channels in an ultrasound imaging system at the remote location. The central service facility produces beamformer control software (i.e., beamforming parameters) that is optimized for the existing functional channels. The optimized beamformer control software is generated based on diagnostic feedback received from the remotely located system via the network, and is downloaded to the remote system via the same network.
