Title: Laser diffraction and scattering-type particle-size- distribution measuring apparatus
Inventor: SHIMAOKA HARUO
IPC: G01N21/05
Filed: 2000-08-04
Abstract: PROBLEM TO BE SOLVED: To provide a laser diffraction and scattering-type particle-size-distribution measuring apparatus wherein the space intensity distribution of diffracted and scattered light obtained when a group of particles to be measured is irradiated with a parallel laser beam can be measured continuously and with high resolution in an angle range wider than that in conventional cases and a particle size distribution in a submicron region can be measured with high resolution. SOLUTION: The diffracted and scattered light obtained when the group of particles to be measured is condensed by a condenser lens 3 over 40 deg. or more from a part near 0 deg.. Its intensity distribution is measured spatially and continuously by a photosensor array 4 which is situated in its focal position. Before the particle size distribution is calculated on the basis of the measured light intensity distribution, an aberration by the condenser lens 3 which is stored by finding the measured result of the light intensity distribution in advance by tracking a beam of light and an error due to attenuation on an optical path are corrected and computed, Thereby, the light intensity distribution of high resolution obtained by spatially and continuously measuring the diffracted and scattered light in the angle range wider than that in the conventional cases is obtained.  The particle size distribution in the submicron region can be measured with high resolution.

Title: Echo canceling system and method for selectively canceling echo in communication channel
Inventor: PEN TSUAN
IPC: H04B3/23
Filed: 2000-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a system that automatically reassigns an echo canceler to another facility in the case that it is decided that a facility to which the echo canceler has been assigned does not generate vast profit from echo cancelation. SOLUTION: The echo canceling system provided with self-deactivation processing of this invention includes an echo canceler and an echo detector employing an adaptive filter. The adaptive filter decodes an estimate value of an echo signal in existence in an unprocessed signal received from a near-end of a communication channel. The echo detector compares the energy of the unprocessed received signal with the energy of the received signal whose echo is canceled. When the difference is high, the echo canceler is left as active. The difference, that is, the estimated echo energy is small, the echo canceler is deactivated and the echo detector selects the unprocessed received signal as its output. In the case that a plurality of channels for echo cancelation is to be served, the deactivated echo canceler is reassigned to serve for another communication channel.
