  • Patent number: 5168506
    Abstract: In radio operation in tactical use, an increased jamming resistance with respect to intentional jamming is required. For protection against intentional jamming, frequency hopping techniques have proven very advantageous in which the signals are transmitted in the form of successive error-protected signal blocks where each signal block is transmitted on a different radio carrier frequency which changes in a pseudo-random manner. With this technique, phase shifts can occur which are greater than half a bit and therefore make analysis of the signal blocks difficult or impossible. It is proposed herein that each received signal block be checked after regeneration in a regenerative repeater, controlled by a bit clock pulse, as to its correct block phase and therefore, respectively, newly establish the block clock pulse phase required for further accurate processing of a signal block.

  • Patent number: 5168556
    Abstract: A method and circuit for reducing the load of the microprocessor unit of a microprocessor controlled, serial interface circuit. The transmission side of the interface circuit has a first auxiliary stage that, dependent on the presetting by the microprocessor unit generates a control bit stream and transmits a data bit stream from a serial bit stream converter stage. A self-generated data bit stream generates prompter signals for the microprocessor unit and the reception side of the interface circuit has a second auxiliary stage that recognizes message changes over a predetermined time period and generates a prompter signal when the message change occurs.

  • Patent number: 5167660
    Abstract: A HF surgery device had a microprocessor and a comparator which in combination generate a control signal which acts on a rectified operating voltage, which drive a HF generator. The HF generator can be modulated with a modulation signal. In order to automatically maintain the effective output power at a constant level in the event of a modulation of the HF generator, the microprocessor forms a reference value from the modulation signal and from a prescribed setting signal for setting a HF output power. The reference value is compared to the operating voltage in the comparator for forming the control signal.

  • Patent number: 5167371
    Abstract: A fan jet nozzle for surface coating, particularly for high-pressure spraying, is created whose inside dome is not fashioned rotationally-symmetrical. The dome interior is semicircular in the one plane of section in which the nozzle slot extends, but is ogive in the plane perpendicular thereto, the plane which is perpendicular to the lengthwise plane of the fan jet nozzle slot. The two sections, semicircular and ogive, steadily verge into one another around the center axis of the nozzle. The dome configuration results in less wear from abrasion of spraying fluid through the nozzle slot, in particular, onto the wall edge between the dome and the nozzle slot.

  • Patent number: 5168388
    Abstract: An optical waveguide device is disclosed which comprises a KTiOPO.sub.4 single crystal substrate and an amorphous optical waveguide formed of Ta.sub.2 O.sub.5 or Ta.sub.2 O.sub.5 doped with TiO.sub.2. A second harmonic generator device in the form of the Cerenkov radiation using the optical waveguide has high SHG efficiency. Since the Cerenkov angle can be made small by optimizing the dimensions, the spread angle of the SHG light can be made small.

  • Patent number: 5165404
    Abstract: A device for biological tissue stimulation continually undertakes an evaluation of the stimulation sensitivity of the biological tissue to be stimulated, so that the stimulation energy can be set at a level just high enough to evoke a tissue response. Each evaluation ensues by stimulating the tissue with progressively lower energy levels, until no tissue response is detected. In order to improve matching of the stimulation energy to the varying stimulation sensitivity, and to keep the number of unsuccessful stimulation attempts, which occur during each evaluation, low, a device is disclosed wherein calculation of the stimulation sensitivity occurs at periodic time intervals, each time interval having a duration which is selected dependent on the variation in the stimulation sensitivity between the two most recently occurring calculations of the stimulation sensitivity. The device may be, for example, a heart pacemaker. A method for tissue stimulation is also disclosed.

  • Patent number: 5166971
    Abstract: A method and apparatus for speaker recognition in a telephone switching system. For a speaker recognition in a system particularly fashioned as an ISDN communications system, speech specimens are input into a telephone terminal equipment (T1, T2) and are pre-processed there, being, in particular, sampled with a sampling rate that is greater in comparison to the standard sampling rate. The samples are intermediately stored in the telephone terminal equipment (T1, T2), are read-out with the standard sampling frequency and are transmitted to a switching system (VA) in which the actual speaker recognition (SPR) is carried out.

  • Patent number: 5165405
    Abstract: In the stimulation of living tissue the reaction thereof is usually superimposed with polarization phenomena to such a degree that the reaction cannot be recognized in the electrical signal. To avoid this problem, a curve of the measured tissue potential is intermediately stored in a first memory after each stimulation, and the intermediately stored curve is then always used for updating the current signal curve. The current signal curve is stored in a second memory whenever an absence of a tissue reaction to the stimulation occurs.

  • Patent number: 5166588
    Abstract: A medical apparatus has an apparatus part which is motor-adjustable relative to a surface in a direction of at least one degree of freedom. A sensing card means comprising a plurality of sensing cards forms a matrix-like grid which is attachable to the surface in a range of adjustment of the apparatus part. The sensing cards each output a signal given the presence of a subject in the region of the respective sensing card. The signals output by these sensing cards are evaluated in dependence upon the desired adjustment direction in such a way that only the sensing card or cards of the matrix-like grid lying in the desired adjustment direction is or are taken into consideration. An adjustment of the apparatus part in the desired adjustment direction is suppressed when at least one sensing card taken into consideration outputs a signal indicating the presence of a subject.

  • Patent number: 5165896
    Abstract: A clamping arrangement for clamping a cylindrical shaft of a tool in a dental handpiece includes a clamping sleeve having resilient tongues for gripping the cylindrical shaft and being capable of being moved radially outward by an adjustable plunger to release the shaft. In order to achieve a largely wear-free tool guidance, the tool shaft is held at least at its distal end of the tool in a guide bushing, which is firmly joined to the hollow shaft. The guide contains an arrangement which enables axial mobility of the plunger, prevents twisting of the plunger so as to enable transmission of the force between the plunger and a manipulator which actuates the plunger.
