Abstract: A system for controlling an electromagnetic clutch for a motorvehicle during a transient state of driving conditions of the motor vehicle. An actual engagement rate signal is obtained in dependence on the speeds of the drive member and driven member of the clutch. A desired engagement rate of the clutch is obtained in accordance with the speeds of the drive member and driven member. The clutch current is controlled so as to converge the actual engagement rate and the desired engagement rate, thereby slipping the clutch in dependence on the transient state.

Abstract: A dial tone detector of improved performance is provided by precise definition of a passband. In one example, virtually infinite roll off is achieved in less than 5 hertz. An incoming analog signal (23a) of at least a predetermined amplitude is limited to produce square wave pulses (23b) which are counted in a first counter (24) over a period of time determined by a periodic RESET signal. A READ signal occuring just before the RESET signal causes either a valid count state or an invalid count state to be stored depending upon the value of the count in the first counter. When a valid count state is in storage, a second counter (30) counts timing pulses while the valid count state persists, whereby in the second counter a count of greater than a predetermined number indicates the presence of dial tone.

Abstract: A picture-taking system (SPI) furnishes a file of images recorded in a memory (3). A segmenting and framing module (M1) isolates, in individual matrices, each of the characters contained by the image file. A module (M2) determines therein primitive shapes by prior determination of the features, and subtraction of the features of the nature of the character. A module (M3) then carries out a description with primitive shapes, through at least one partially ordered list of primitive shapes, which a module (M4) compares with standard descriptions expressed in the same way in a data base (M5). Recognition of the characters proper is performed by determining distances between the description encountered and the standard descriptions.

Abstract: 1. Circuit arrangement for the analog/digital conversion of signals of varying level. 2.1 In such a circuit, it is already known to apply the signals to the analog/digital converter via a dynamic compressor and to control the level in such a manner that the dynamic range of the analog/digital converter is utilised at approximately all levels. 2.2 At the beginning of an adaptation process, the occurrences when the dynamic range is exceeded are counted and controllable current sources are driven via a digital/analog converter which extend the step size of the quantisation steps of the flash converter. This is done until a stead-state condition is reached. A flash converter is preferably used as analog/digital converter. 2.3 The measure can be applied in digitised video devices which are intended to process signals from different signal sources and thus of different input level.

Abstract: A method of controlling speed reduction ratio for a continuously variable speed transmission comprises a running mode control method which is carried out when an accelerator opening is opened, an engine brake mode control method which is carried out when said accelerator opening is substantially closed and a transient control method which is carried out over a predetermined period of time (TEB) when the control is shifted from a state under the engine brake mode control to a state under the running mode control. The transient control method comprises the steps of obtaining a corrected R-REF engine speed immediately after the shift to the running mode control (S4,S6), by adding a difference (OFFSET) between the actual engine speed and the R-REF engine speed to the R-REF engine speed set corresponding to the current accelerator opening, obtaining a further corrected R-REF engine speed during a predetermined period of time (TEB) following the shift (S11,S6), by adding a correction which is obtained by gradually decreasing the speed difference with time (S9,S10,S11) to the R-REF engine speed, and controlling the speed reduction ratio (57) so that the actual engine speed coincides with the corrected R-REF engine speed over the predetermined period of time.

Abstract: In a chain of fully differential amplifiers, comprising at least two cascaded amplifiers, the stabilization of the output common mode voltage of an amplifier is implemented by sensing the value of such a voltage by means of a dedi­cated terminal connected to a circuit node corresponding to the sources connected in common of the input differen­tial pair of transistors of an amplifier which follows in the chain of cascaded amplifiers. Such a voltage is compa­red with a reference voltage to which, by means of a le­vel shifting circuit, a voltage equivalent to the thre­shold voltage of the said transistors forming said input pair is subtracted thus obtaining an error signal of the out­put common voltage of said amplifier to be stabilized which may be applied to a dedicated control terminal thereof. The system of the invention provides for the sensing of the output common mode voltage without loading the ouputs of the amplifier to be stabilized and it is more easily implemen­ted than known systems.
