A multi-carrier information transceiver that exhibits robustness against radio frequency interference signals present in the communications channel. The detection of additional values and the calculation of the location parameter and dispersion parameter from the existing and additional values is carried out until the dispersion parameter reaches a threshold value, and then, the location parameter corresponding to the dispersion parameter is used as the characteristic for the correction of the reading of the Coriolis mass flowmeter. , an ophthalmic photochromic article, such as a lens, in which the article includes a polymeric substrate, such as a thermoset or thermoplastic substrate, a photochromic polymeric coating appended to at least one surface of the substrate, the photochromic polymeric coating containing a photochromic amount of at least one organic photochromic material, e. The verify circuit stores a target threshold voltage that is compared to the read threshold voltage to generate an inhibit signal when the target and read threshold voltages are substantially equal. Sensor data can be received from the phase front sensor and can be processed by the phase front controller.
