Title: System and method for processing periodic signal or cyclostationary signal
Inventor: HILTON HOWARD
IPC: G06F19/00
Filed: 2005-04-06
Abstract: <P>PROBLEM TO BE SOLVED: To precisely analyze a periodic signal or cyclostationary signal.  <P>SOLUTION: In one representative embodiment, multiple ensembles of samples of a periodic or cylcostationary signal are processed in a time aligned manner. The sampling rate of the processing system is adjusted so that an integer number of sampling intervals equals the period of the signal. A cyclic counter 103 is programmed to reset according to the integer number. During operation, the cyclic counter is incremented when each sample is received. Continuous operation of the cyclic counter with the capturing of samples enables precise time alignment between ensembles of samples. Specifically, the beginning of a discrete ensemble is identified by a reset of the cyclic counter. Because each ensemble is time aligned, further processing (e.g., coherent averaging) may occur without post-processing to time-shift each sample to achieve the time alignment.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

IPC: G02B6/38
Filed: 2005-04-07
Abstract: <P>PROBLEM TO BE SOLVED: To properly and quickly determine the quality of a front end face of an inclined spherically polished ferrule with respect to spherical eccentricity.  <P>SOLUTION: The ferrule 420 held in an optical connector plug is held in such a state that the central axis W is inclined by an inclined polishing reference angle θ<SB>0</SB>with respect to the optical axis Z to measure the front end face 422. Measurement values ε<SB>1</SB>, d<SB>1</SB>for the angular displacement ε and the distance d and the radius of curvature R of the front end face 422 are acquired. On the basis of the acquired result and the correspondence relationship between the angular displacement ε and the distance d, a reference distance d<SB>0</SB>when the angular displacement ε is zero is acquired, and the expected value of the distance d when the angle is displaced to a permissible boundary value ε<SB>m</SB>is acquired. The acquired expected value determines the quality of the ferrule 420 with respect to the spherical eccentricity on the basis of whether or not the amount of spherical eccentricity is equal to or below the permissible threshold.  <P>COPYRIGHT: (C)2007,JPO&INPIT
