Inventor: KAMMERER BERHARD DIPL ING

Granted: 1989-02-23
Abstract: 1. Method for determining the boundaries of signals mixed with background noise, particularly of signal boundaries for speech processing of words spoken against a background noise, the criterion used for distinguishing between a signal of interest and the background signal or background noise being their amplitude characteristics, characterized in that - in a first step, a signal or noise recorded and subsequently preprocessed, namely an input variable (E), is observed with respect to its mean amplitude (A) and its first transmission frequency (N), referred to a reference variable (R), and its range of fluctuation (dN) within a predetermined time interval, the transmission frequency (N) being averaged from individual transmission frequencies and the range of fluctuation being determined by the maximum deviation of the individual transmission frequencies, - auxiliary variables (S1, S2, N2) are derived from the relevant variables obtained, which auxiliary variables are defined as follows : S1 = a*A+c S2 = b*A+c N2 = N/d, the variables a, b, c, d being constants which are determined by empirical values or by the type of the signal of interest, - in a second step, the current transmission frequency (N1), referred to a reference variable (R), is determined within a time pattern needed for adequate resolution, - one of the previously derived auxiliary variables (S1 or S2) is allocated to a weighting variable (S) in dependence on the observed derived transmission frequency (N2) with its range of fluctuation (dN) and the current transmission frequency (N1), - the current input variable (E) is measured by means of this weighting variable (S), - an operating (O1) dependent on the position of the input variable (E) relative to the weighting variable (S) is performed, - two boundary values (UG, OG1) are determined on the basis of the type of the signal of interest, - the result of the operation (O1) is limited towards the bottom by the first limit value (UG), - the existence of a signal of interest is detected when the second upper limit value (OG1) is reached, - the precise beginning of the signal (SB) is in front of the relevant detection time (ZE1) by a defined time interval, - in a third step, the position of the input variable (E) relative to the weighting variable (S) is evaluated by a further operation (O2) in such a manner that the non-existence of the signal of interest detected in the second step is established using a second limid value (OG2) which has been previously determined on the basis of the type of the signal of interest, the further operation being defined as follows : O2 = 02+1 for ¦E¦ < S O2 = O in all other cases or OG2 in all other cases or O2 - 1 for ¦E¦ < S, - and the precise signal end (SE) is in front of the relevant detection time (ZE2) by a defined time interval.

Abstract: This invention relates to an electrically switchable fiber optic directional coupler. Two oppositely oriented blocks of an interaction material are placed adjacent the fibers in an evanescent field coupler. Application of an electromagnetic field to the interaction material increases the refractive index of one fiber and decreases the refractive index of the other. The change in refractive indices of the blocks of the interaction material increases the propagation constant of one fiber and decreases that of the other fiber. The coupling of optical signals between the fibers may be varied between zero and 100% by controlling the aplied field to change the propagation constants between values that provide complete cross coupling of light from one fiber into the other and straight through propagation provides an electrically controllable switching action.

Abstract: A stabilised mount [e.g. for an antenna (13)] has two gyroscopic rotors (23, 24) mounted in such a way that they can pivot about orthogonal axes (26, 27). Rewinding of the antenna (13) (to avoid undue twisting of the electrical cables) is liable to cause a violent destabilisation of the mount because of the gyroscopic action of the rotors (23, 24). To prevent this destabilisation the rotors (23, 24) are locked against the aforementioned pivotting action during the rewinding procedure.

Abstract: During the transmission of speech the relevant sound levels are registered.  The peak level threshold is set which is then slowly reduced until a new peak exceeds the threshold.  The threshold is then rest to the new peak value, and the procedure repeated.  The minimum value is treated similarly, but the set minimum threshold is slowly raised until a lower value again resets the threshold. Maximum and minimum thresholds (SW1,SW2) are operated upon to form a difference threshold value (SW3).  When the difference is large the threshold (SW3).  When the difference is large the threshold (SW3) tends to the peak value (SW1), when low to the minimum value (SW2).  The peak value decay time constant is in the range 3-5 seconds, the minimum value rises with a time constant between 6 and 12 times that of the decay.  The choice of times ensures that short pauses between words and sentences have no significant influence on the measurements.

Preferably, a positive stop arrangement to maintain an adjusted position is provided; or the adjusted position may be infinitely variable, for example by clamping the spring element in position by means of an eccentric.

Abstract: According to the invention a flat lid for lead-acid accumulators is manufactured with elastic seats for the connection of the poles. Around each opening (4; 31) for the passage of the poles (5; 23) of an accumulator there is an elastic diaphragm (6; 27) the longitudinal profile of which is suited to make it elastically deformable in its axial direction. A pole (5; 23) of the accumulator is connected with the diaphragm by means of the ring-shaped seat (8; 20) being present on the end opposed to the area (19; 30) for the connection with the lid (1; 40).   If a lengthening of the pole (5; 23) of the accumulator eventually occurs during its life-span, it will be absorbed by the deformation of the diaphragm (6; 27) so that the lid (1; 40) will not be subjected to stresses which might damage or disconnect it with serious consequences for the accumulator.
