Title: Residual echo elimination with proportionate noise injection
Inventor: GENTER ROLAND
IPC: H04B3/23
Filed: 1991-07-30
Granted: 1995-04-11
Abstract: An echo canceller (20) with an adaptive convolution processor (50) for computing and subtracting an anticipated echo, in-cluding a nonlinear processor (82) which attenuates the error signal over a continuous range. A noise injection source (83) cou-pled to the send output variably injects an artificial noise signal in inverse proportion to error signal attenuation. The gradual ad-justment of error signal attenuation and maintenance of the output noise level at the average background noise level of the input, make operation of the echo canceller (20) unnoticeable to a far end listener.

Patent CA-2098934-C (CA)
Inventor: SOUDERS KEITH ALAN
IPC: H04B15/00
Filed: 1993-06-22
Granted: 1997-08-26
Abstract: The effect of non-linear distortion on a received signal point is reduced by the use of a circular limiter. In particular, the circular limiter computes the distance of the received signal point from the center of the signal point constellation. If this distance exceeds a desired limit, then both dimensions of the received signal point are reduced by the same factor to maintain the original phase. This reduction in the dimensions of the received signal point decreases the corresponding errorsignal that is calculated by a Viterbi decoder. As a result, this further reduces the value of the accumulated path metrics of the Viterbi decoder which results in animprovement in system performance. In addition, the circular limiter also realizes a slight improvement in system performance against additive white Gaussian noise. The value of the limiting distance can either be predefined, or determined adaptively to match channel conditions of the communications system.

Granted: 2001-01-30
Abstract: In the process, according to the invention, for the compensation of changes of the wavelength of the light source of a fibre-optic gyro having a closed reset control loop, use is made of the finding that the voltage range which is required for a phase shift of 2.pi. in a phase modulator (4) is dependent upon the light source wavelength. Since the voltage required for the 2.pi. phase shift is regulated, according to the invention the voltage value which is thus available can be utilized for the compensation of a change of the light source wavelength or of the scale factor. Moreover, in order to achieve a precise compensation it is necessary to take into consideration the temperature of the phase modulator (4).

Abstract: A vacuum head having a confinement zone with a portion of surfaces inside a water pool, under the vacuum head, for cleaning surfaces of the floor and adjacent sides, inside a water pool. A water outlet is mounted within the confinement zone, whereby the presence of water in the confinement zone generates a flow of water driven toward the water outlet. A plurality of water jets within the confinement zone impinge water upon the portion of surfaces, under the vacuum head, for the water from the water jets to hit the portion of sur-faces within the confinement zone, to remove dirt from said portion of surfaces, and said dirt together with said water to be substantially confined within the confinement zone, and be displaced along the flow of water driven toward the water outlet. A method for cleaning surfaces of the floor and adjacent sides comprises creating a negative pressure zone at least partially impermeable to the water inside a water pool to obtain a confinement zone having a flow of water driven toward said water outlet, and inside said negative pressure zone, impinging water upon surfaces for cleaning inside a water pool.
