  • Method for in-situ measuring and in-situ correcting or adjusting a signal process in a hearing aid with a reference signal processor
    Patent number: 6658122
    Abstract: The application relates to an in-situ method to measure and adjust the sound signal presented to the eardrum by means of a hearing aid and a hearing aid employing such a method. The hearing aid comprises microphone (1), signal processing system comprising digital signal processor (2) for transforming the microphone signal into a transformed signal according to a desired transformation function, sensor (4) sensing the sound signal appearing in front of the eardrum and comparator (5). Reference signal processor (6) generates a reference signal based on the output of microphone (1) and representative of the desired sound signal in front of the eardrum. A transfer function between receiver (3) and the output of sensor (4) is established to correct the process in reference signal processor (6). The sound signal in front of the eardrum is sensed, fed back and compared in said comparator (5) with said reference signal.

  • Remotely controlled, especially remotely programmable hearing aid system
    Patent number: 5710819
    Abstract: In a remotely controllable, especially remote-control-programmable heating aid with an external control device (1) with a keyboard (2), display device (3) and a data processing device (4) and also a hearing aid (9) controllable by the control device (1), in the control device there is a signal generator (11) actuatable and controllable via the keyboard (2) and the data processing device (4). This generator is releasably connected by a cable (12, 13, 14) to the heating aid so that the control device (1) can be used together with a heating aid to determine the hearing curve or, in general, the audiometric values of the wearer of the hearing aid in real conditions.

  • Dihydroxyphenylethylaminoalkyl theophyllines
    Patent number: 4153696
    Abstract: There are prepared compounds of the formula ##STR1## in which T is the theophyllin-7-yl group and alk is a straight or branched alkylene chain with 2 to 4 carbon atoms and salts thereof. The compounds promote circulation and produce a marked and persistent increase in renal circulation.
