  • Patent number: 10723450
    Abstract: A rotor or propeller may have rotor blades and a passive pitch angle adjustment apparatus. The passive pitch angle adjustment apparatus may include levers, rods, and central rod. Levers may be connected to rotor blades and rotate them around a respective pitch axis. Rods may be connected to levers and mechanically link levers with each other via central point that is located outside rotor plane. Central rod may connect central point with base point that is located in a longitudinal direction of rotor axis. The passive pitch angle adjustment apparatus may enable a cyclic pitch adjustment of the rotor blades and block a collective pitch adjustment of the rotor blades.

  • Patent number: 4276781
    Abstract: A method of and apparatus for accurately adjusting a hearing aid. First a wide-band reference signal of relatively low sound level, e.g. 40 to 50 dB, is reproduced via a loudspeaker. The gain of the hearing aid is adjusted so that the person wearing it can just hear this reference signal. Then, in addition to the reference signal, a periodically recurring narrow-band signal having a duration of approximately 150 msecs is reproduced and the range of the optimum sound-level of speech is determined for different central frequencies of this narrow-band signal. The range thus determined is compared with the range of optimum sound-level of speech for persons with normal hearing and subsequently the setting of the hearing aid is corrected so that the sound level experienced as a pleasing sound level of speech by the user of the hearing aid falls within the sound-level range which is pleasing to persons with normal hearing.
