Title: Contaminant identification and concentration determination by monitoring the temporal characteristics of an intracavity laser
Inventor: ATKINSON GEORGE H
IPC: G01N21/39
Filed: 1999-11-23
Granted: 2002-05-21
Abstract: A method and apparatus (10) for detecting the presence of a specific concentration of gaseous species within a calibrated range in a gas sample are disclosed. The ILS gas detection system (10) of the present invention simply comprises an ILS laser (12) and an optical detector (16). However, the spectral bandwidth of the ILS laser (12) is preferably entirely included within one of the absorption bands or regions assigned to the intracavity gaseous species being monitored. Thus, within the calibrated range, the presence of the gaseous species changes the temporal characteristics of the ILS laser (12). Consequently, only a temporal characteristic of the output of the ILS laser (12) need be monitored in order to quantitatively determine the concentration of the absorbing gaseous species when using the ILS method of the present invention.

Title: Method and device for estimating input power in a cable modem network
Inventor: LYNAUGH KEVIN
IPC: H04L25/00
Filed: 2000-11-24
Granted: 2002-11-21
Abstract: A method for estimating the input power to a cable modem includes generating a look-up table containing AGC integrator accumulator values corresponding to selected frequencies and amplitudes. The look-up table is generated by first constructing a calibration matrix by inputting a plurality of calibration signals having known input frequencies and known input power levels into the cable modem's receiver, and recording AGC integrator accumulator values corresponding to several frequencies and power levels over a selected operating range as calibration points. Next, an interpolation and extrapolation process generates the look-up values corresponding to the frequencies and amplitudes in between the calibration points. During modem operation, the modem estimates the input power by checking the AGC integrator accumulator value corresponding to the input frequency and amplitude. Because the look-up table values are based on the cable modem's actual operating characteristics, the estimated input power will reflect any variations or irregularities in the modem's operation, such as gain non-linearities, frequency ripple, or temperature effects.
