    摘要: Methods and systems for updating the adaptive filter of an echo canceller. A method of updating the adaptive filter of an echo canceller in which an estimated echo is resolved from a received signal and then subtracted from an incoming echo-contaminated signal so as to produce a filtered output signal, includes: obtaining a corrected impulse response of an echo reconstruction filter (ERF); calculating specified decision measures usable to decide whether to prospectively apply the corrected ERF impulse response or a current ERF impulse response; determining whether application of the corrected ERF impulse response would result in improved echo cancellation; and updating the ERF to apply the corrected impulse response, when it is determined that the updating would result in a lower residual echo.

    摘要: The invention concerns a process and an apparatus for measuring the anisotropy value of form changes in normal direction in sheet metals (the r-value). In course of a standard tensile test, the longitudinal change of dimension of the test piece is measured. When a preselected value of change of dimension in longitudinal direction which is characteristic of the material of the test piece, is reacted during the measuring process, the appertaining change of dimension in lateral direction is measured. Thereafter, an r-value is selected from the r-values corresponding to different changes in dimension in lateral direction at a preselected longitudinal change of dimension, which is closest to the one measured at the change of direction in lateral direction. The apparatus comprises comparator and switching units which are connected to signal transmitters converting changes of dimension in longitudinal direction into electric signals. The comparator and switching units compare the electric input signals with reference signals. After the preselected change of dimension in longitudinal direction is reached in the course of the measuring process, these units send an interlocking signal to a further switching and decoding unit. This further switching unit is connected to a comparator unit which compares the electric signals corresponding to changes of dimension in lateral direction with the reference signals.

    摘要: The apparatus of the invention comprises means for examining the human eye for the onset of glaucoma. The eye undergoing examination forms one plate of a virtual capacitor the other plate of which is formed by a gas nozzle. The body of the person undergoing examination and the gas nozzle are connected to the input of a signal converter the output of which is sampled at a predetermined instant by a sampling and sample-holding means. A gas jet from the nozzle is directed at the eye and a sample made of the output of the signal converter. An indicator connected to the sampling and sample-holding means provides a measurement of the deformation at the surface of the eye caused by the dynamic pressure of the gas jet. Sampling may be carried out at moments determined by the systolic rhythm of the person being examined. Preferably samples are taken at the systolic and diastolic moments thereof, the samples being compared to give an indication of the dynamic performance of the eye.
