    Abstract: Inspecting a retaining ring of a dynamoelectric machine includes placing an optical device in a stationary component of the dynamoelectric machine and directing the optical device toward a radial view of the retaining ring. An image is obtained and transmitted of a circumferential portion of the retaining ring, using the optical device during rotation of the rotor. Identification is made of a location of one or more stress cracks forming and visible at the circumferential portion of the annular edge. Further, a structural condition is determined for at least one location on the retaining ring using a metric to identify a value of the metric exceeding a predetermined acceptable value of the metric.

    Abstract: A compact, portable, clinical instrument dedicated to hemoglobin determination employs an L.E.D. light source with a peak output wavelength of about 553 nanometers and a yellow-blocking filter with a long wavelength cut-off not longer than about 565 nanometers. Thus, the relative amount of energy incident upon the blood sample in the 540 nm. hemoglobin absorption band is maximized. In addition to the L.E.D., the photodetector and the amplifying, inverting, log conversion, digital conversion, display and power supply regulation circuits are also exclusively solid-state. The display is of the reflective or liquid crystal type, and the power supply regulator is a sophisticated integrated circuit containing the equivalent of many discrete components. As a result, current consumption is minimized, and battery life and instrument accuracy are maximized. As an alternative illumination source, an infra-red L.E.D. can be employed, and the instrument is then capable of blood turbidity measurement. In either case, the L.E.D. illumination source is powered by a constant-current regulator, which minimizes errors due to fluctuations in illumination intensity.
