Abstract: Tone-detection method for a call-progress process which detects at least one tone in a multifrequency dual-tone signal in a telecommunication apparatus having digital signal processing resources. The method involves the step of:
     computing (201) the value of the energy of the signal,   processing (201) said received signal to determine the existence of one or two tones in said signal,   applying a second-order or fourth-order autoregressive process in response to said determination and performing (203, 208) a first estimation of the autoregressive parameters of said received signal,   performing a digital band-pass filtering operation (205,210) adjusted to the result of the estimation of said autoregressive parameters to provide a partial elimination of the noise existing on said received signal,   reapplying (205, 210) a second-order or fourth-order autoregressive process in response to said determination and performing a final estimation of the autoregressive parameters of said received signal,   computing (206, 211) the values of the frequencies each tone from the value of said estimated parameters.   
     The determination of the number of tones existing in the signal is achieved by the computation of the ratio:       
 which is theorically equal to 2 in the case of a unique tone, and conversely should be 4 in that of a dual tone. The first and final second-order autoregressive process are based on the predicting function having the z-transfer function:       
 and which is associated with a Least Mean Square algorithm continuously adapting the parameters of the predictor in a sense allowing the minimizing of an error signal. On the other hand, the first and final fourth-order autoregressive process are based on the predicting function having the z-transfer function:       
 To increase the accuracy of the tone-detection mechanism, the second-order autoregressive function is performed with the value of a2 parameter being constantly fixed to -1. Similarly, the fourth-order autoregressive process is performed with the values of a3 and a4 being respectively equal to a1 and - 1. The digital filter which provides the suppression of most of the noise existing in the signal having an unique tone is based on the z-transfer function:       
 In the case of a dual-tone, the filtering is based on the function:

Title: Process and device for producing thin sections by means of a microtome.
Inventor: IZVOZTCHIKOV ILIA BORISOVITCH
IPC: G01N1/06
Filed: 1993-07-05
Abstract: The description relates to a process and device (10) for producing thin sections (98) cut from a thin-section sample (16) by the cutting blade (20) of a microtome (12), in which the thin sections (98) are transferred to a liquid bath (40). To prevent the undesired compression of the thin sections (98) during the cutting process and also to ensure that they extend properly, the thin sections (98) are transferred from the cutting blade (20) to the liquid bath (40) by a liquid flowing from the blade (20) to the bath (40) at some distance from it. It is thus advantageously possible to divert the flowing liquid as desired by means of a deflecting device (56) to said liquid bath (40) or to a waste container (52) so as to separate 'good' thin sections (98) from first cuts, coarse sections or other unsatisfactory thin sections (98) in a simple manner.

Abstract: An automatic offset control circuit comprises a differential output preamplifier (102) having an offset adjustment function, further comprising an average detector (106), a peak detector (107), and a differential input amplifier (108). The average detector (106) generates a reference voltage representing an average value of a positive output (V+) and a negative output (V-) of the preamplifier (102). The peak detector (107) outputs a peak voltage representing a peak of the negative output (V-) of the preamplifier (102). The differential input amplifier (108) compares the peak voltage with the reference voltage to output an offset adjustment signal to the preamplifier (102). The offset adjustment signal is obtained based on a difference between the reference voltage and the peak voltage. A bottom detector (109) may be used instead of the peak detector (107), provided a bottom value is detected using the positive output of the preamplifier.
