Abstract: A multi-transmitter telemetry system remotely controls and modifies the operating parameters associated with a plurality of addressable transmitter modules connected to collect data from a plurality of sensors. Control instructions remotely provided to each transmitter module include addressing data identifying the transmitter module to implement the control instructions. Although each transmitter module decodes the control instructions, only the addressed transmitter module implements the provided instructions. In this way, individual transmitters employed in a multi-transmitter telemetry system may be individually addressed and remotely controlled.

Abstract: A rotor assembly comprised of a multiplicity of blades mounted around the periphery of a disk has the blade tips ground to great diametrical precision when the assembly is rotated at a high speed in excess of 1000 rpm in a special grinding process. Individual blade lengths are dynamically measured while the assembly is being ground. These measurements are used to control the grinding process and to also permit accurate assessment of the quality of assemblies in general. A laser triangulation measurement system is used. It is capable of very fast reading of blade length since 3300 or more blades may pass by the measuring point each second.
