摘要： A device for displaying the value of a quantity represented by input data comprises a mobile indicator member (24) driven by a stepping motor (20), a control circuit (18) for this motor for delivering drive pulses to the motor in response to the input data to move the indicator member to a position corresponding to the value of the quantity, and a dial (26) for showing an indexing system, for example a scale, which cooperates with the indicator member to indicate the value at least approximately. The dial comprises a liquid crystal, electrochromic or electroluminescent electrooptical display device (26) which displays the indexing system in response to signals from another control circuit (28) when the latter receives an activation signal. The device enables values of a single quantity situated in different ranges or values of distinct quantities to be indicated, by making the cell selectively display corresponding indexing systems. A specific application of the device is for automobile dashboards.

摘要： The device comprises a piezoelectric transducer, a primary battery, and a circuit which applies a control voltage to the transducer or which short-circuits the latter depending on the state of a control signal. The control voltage is produced by a voltage increasing circuit comprising a coil, a diode and a capacitor constituted by the transducer, that are connected in series, in that order, across the terminals of the primary battery, and an oscillator responsive to the control signal to control a transistor in such a manner that it either alternately produces and cancels a short circuit across the terminals of the circuit formed by the diode and the transducer or is permanently blocked. A second transistor is also responsive to the control signal to short-circuit the transducer when the first transistor is blocked. The device is simpler, cheaper and consumes less electrical power than known devices.

摘要： The present invention comprises measuring, upon application of a drive pulse to the actuating coil 5 of the stepping motor, the variation in the magnetic induction flux in the stator of the motor, and interrupting the drive pulse when the variation in flux reaches a predetermined value. Measurement of the variation in flux may be effected, for example, by detecting the current in the actuating coil and integrating the difference between the supply voltage of the actuating coil and the product of the current by the d.c. resistance of the coil, or by providing an auxiliary detection coil 71 and integrating the voltage induced therein in an integrator 73, 74. When the integrator outputs exceeds the magnitude of either a positive or negative reference voltage, a comparator circuit 78, 79, 81 provides the signal to a circuit 13 to terminate the drive pulse.The foregoing abstract is not to be taken as limiting the invention described herein, and in order to understand the full nature and extent of the technical disclosure herein, reference should be made to the accompanying drawings and detailed description.

摘要： A detection device has a transducer (10) for emitting and receiving series of ultrasonic pulses. An integrator (23) integrates echo signals resulting from ultrasonic pulses within a time window so as to produce an integral value. A time-delay circuit (28) is used to control the instant of opening T1 of a time window and a control circuit (25) determines an average value of a number of n integral values and for loading the values of the opening a instant T1 into the time-delay circuit (28) so as to maintain the average value at a steady value. The control circuit (25) determines the average value by loading a first value of T1 in the time-delay circuit before the integration of the first x echo signal and a second value of T1 in the time-delay circuit before the integration of the second n-x echo signals.

摘要： The hands of the timepiece are connected to a barrel spring which also drives the rotor of a generator at a speed greater than a desired speed Vc. The electric energy supplied by the generator energizes a slaving circuit that includes a transistor which short-circuits the coil of the generator and thus brakes the rotor down to a speed less than the desired speed Vc when a comparator indicates that this rotor is ahead with respect to its theoretical angular position. A limiting circuit limits the duration of the braking action of the rotor to a fraction of the period of the a.c. voltage supplied by the generator. This arrangement ensures that the slaving circuit is adequately energized even if the rotor is substantially ahead.
