Patent DE-2920041-A1 (DE)
Inventor: KUHN MICHAEL DIPL ING DR
IPC: G06V30/194
Filed: 1979-05-18
Abstract: The characteristic values are obtained from the signal to be verified, e.g. in the case of a voice signal the total energy in the individual frequency spectrum ranges, and these characteristic values are quantified. The frequency with which the individual partial ranges of the quantified characteristic values occur is found during a sampling phase, and these frequencies are stored. In the test phase, the signal is analyzed in the same way and the stored frequencies of the partial ranges into which the characteristic values of the signal to be verified have fallen are multiplied and compared with a threshold. In an arrangement for implementing the method, there is a characteristic store with a store address for a multi-digit binary number for each partial range of each characteristic. This store is addressed by a counter, the positions of which are allocated to the individual characteristics or spectrum ranges of the voice signal, and by the numbers of the partial ranges of the characteristics found during the analysis into which the characteristic values of the signal to be analyzed have fallen. In the sampling phase the content of each addressed store address is raised by 1 and in the test phase the frequencies obtained in the store addresses addressed are multiplied together. When a voice signal is processed for verification of the speaker, with the stepwise formation of the long-term spectrum, the intermediate values are compared with a range limit of a partial range read out from a range limit store and increased by 1 on exceeding a number allocated to this characteristic in an intermediate store. In this manner, it is possible at the end of the voice signal, immediately and without any further processing steps to obtain the quantified characteristics in the form of the numbers of the partial ranges which can then be used to increase the frequencies in the characteristic store. A summation over all spectrum values is made to standardize the incoming voice signals. Subsequently, to all spectrum values is added a given fraction of their value, performed in the simplest manner by position shifting, until the sum of all spectrum values exceeds a predetermined constant. Thus the determination of the quantified characteristics or the partial range sums is immediately effective. The multiplication of the frequencies may be replaced by the addition of the logarithmic frequencies.

The diode prevents inversion. The auxiliary transistor is off in normal operation.
Patent DE-2941138-A1 (DE)
Inventor: JAUNIN JEAN-PIERRE
IPC: G04F10/00
Filed: 1979-10-10
Abstract: A timepiece having chronograph features has an electronic digital display capable of displaying six digits. In the chronograph operating mode these are normally minutes, seconds and hundredths of seconds. Should the instrument run for more than one hour prior to a stop or split operation, then during such operation a detector and a timer will cause hours alone to be displayed alternating with the remaining information (minutes, seconds, hundredths of seconds). Thus a six digit display may be employed for eight digit information.

Title: Correction system for vehicle magnetic compass - obtains correction function for each indicated bearing by fourier analysis of error curve
Inventor: ROGGE JOACHIM DR ING
IPC: G01C17/38
Filed: 1979-11-16
Abstract: The system has the vehicle arranged in different directions in a region which is free from parasitic magnetic fields and for each direction a comparison is made between the actual bearing and the indicated bearing, to obtain correction values. The vehicle is driven slowly around a circular path and the indicated bearings provided at given spacings around this path are stored until more than a complete circle has been travelled. The arc length (i.B) to each individual measuring point for which a measured value (alpha i) is stored is obtained using a geometric formula to obtain the error points. The curve through the error points is subjected to Fourier analysis to give a compensation function which gives the correction value for compensation of each indicated bearing angle.

Patent DE-3006025-A1 (DE)
Title: Hydropneumatic intensifier for filter press - with float for feed pump control and compressed air admission
Inventor: BIHR OTTO
IPC: B01D25/30
Filed: 1980-02-18
Abstract: A hydropneumatic intensifier to load a filter press with a suspension for a separation of solids and water is equipped with a float. When this makes a contact at the highest level of the suspension, the compressed air is admitted to the intensifier and the feed pump is cut off. Another contact at the lowest level cuts the feed pump in again. A pump supplies the suspension from the basin to the filter press via an intensifier. A float interrupts a contact at the highest level and cuts out the pump and applies high-pressure air to the space above the suspension. When the lowest level is reached, the contact is made and the pump is switched ON. Admission of compressed air to the nozzles by opening Valve can speed up the filling and drying operation. This eliminates the trouble caused by high-pressure diaphragm or screw pumps and speeds up the filtration cycle.

Title: Piezoelectric oscillation quartz crystal plate - has specified width to length relation for increased attenuation of secondary waves
Inventor: BRIESE WOLFGANG ING GRAD
IPC: H03H9/02
Filed: 1980-06-14
Abstract: The piezoelectric oscillation crystal is a rod-shaped quartz crystal plate of DT-section. In order to attain the optimum secondary wave attenuation, its width-to-length relation is chosen in the range of 0.25 to 0.35, pref. 0.3. In this range the deep secondary resonance has a relatively great frequency spacing from the main wave. The higher frequency secondary resonances are strongly inter-coupled, thus being of high ohmic nature. In this manner they do not form interferences even if the oscillator is used in filters. The frequency dependence on temp. corresponds to a parabola. In this manner the attenuation of the secondary waves, partic. in filter applications is considerably increased.
