Definitions

  • the invention relates to a digital hearing aid according to the preamble of claim 1.
  • the invention also relates a method for operating a digital hearing aid the preamble of claim 7.
  • the user of the hearing aid is now generally forced to switching the hearing aid off and on again and thus initializing of the hearing aid and reloading the canceled one Program. It arises for the user the hearing aid may be substantial and disruptive Downtime during which the user manually owns the hearing aid must reactivate and possibly even distracted is, so that he is exposed to an increased risk of accidents becomes. The user interrupts the signal transmission perceived as disturbing. The malfunction could also cause harmful levels at the output of the hearing aid if it is not recognized in time.
  • a remote-controlled hearing aid emerges from CH-A 680 249, the actual hearing device worn on or in the ear and has a handheld transmitter as an operating device.
  • the hearing aid contains electronic reception, control and amplifier modules and the control unit is equipped with a circuit, with which periodic control signals are generated and which are received and processed by the handset if there is no or no reception an alarm signal of these control signals in the hearing apparatus is triggered.
  • FR-A-2 536 878 is a restart circuit for one Processor known, which is a properly delivered Processor signal tracks and automatically a restart signal generated for the processor once the frequency the processor signal changes.
  • the invention has for its object a digital hearing aid and a method for operating a digital hearing aid offer a temporary failure of the digital Avoid hearing aids in the event of a program sequence disruption.
  • the digital hearing aid has one Monitoring element to determine a failure or a Malfunction of the sequence program and secondly an activation element, which in the event of a detected failure or malfunction the sequence program an automatic restart of the sequence program causes.
  • this failure is caused by the monitoring element determined and it is after stopping a Signals to the activation element automatically - without manual Add and necessary user response - a restart and reload the program.
  • the hearing aid according to the invention thus also has a program fault an increased ease of use and increases the Safety when wearing a hearing aid.
  • the monitoring element not just a malfunction of the program flow fixed, but also monitors fluctuations in the supply voltage and leads if necessary - if the supply voltage drops below an adjustable limit - likewise reload the program.
  • monitoring element and activation element executed as separate components but also as a combination component become.
  • a digital counter provided with the unit for input / output of data, a clock and the processor of the digital hearing aid connected is.
  • one is monostable Flip-flop provided with the unit for input / output of data as well as the processor is connected.
  • the invention a Schmitt trigger element, which after the monostable multivibrator and upstream of the processor is. This makes the analog output signal the monostable Flip-flop into discrete “1” or “O" signals Control of the processor converted.
  • a method according to the invention has which uses a digital counter, the process steps a) - e) on. During these process steps, periodic resetting of the undisturbed program flow Digital counter provided. When a program malfunction occurs the digital counter is not reset and overflows.
  • Adjustability of the counting frequency and the counting interval of the Digital counter can change its response sensitivity so that e.g. extremely short-term, possibly yourself self-correcting malfunctions from the digital counter not be recorded.
  • the periodic reset of the digital counter when there is no interference Program sequence is advantageously done according to claim 12 by a periodic reset signal of the input / output unit of data or the processor of the digital hearing aid.
  • the inventive method for process monitoring according to claim 13 uses a monostable in its implementation Flop.
  • the latter is in normal program execution periodically triggered, i.e. activated.
  • the monostable falls after an adjustable time interval Flip-flop in the event of a program error in its deactivated state back and generates a reset pulse.
  • Subclaims 14 to 16 include process claim 13 Realizations of the method steps according to claim 13 with already presented in previous claims Circuit elements.
  • the latter can also be done by importing the respective the causes of the interference-related signals in one (Queryable) memory of the processor happen.
  • Data e.g. time of occurrence, time frequency and other statistical parameters
  • FIG. 1 shows a processor clocked via a clock generator 5 6, which the respectively called programs for signal processing loads into the program memory 10. This processes the signals and gives signal data to the unit 4 for input / output of data further.
  • the latter unit 4 is connected to the processor 6, but also with the monitoring element 1.
  • the monitoring element 1 now determines if in the program memory 10 loaded program a fault occurs and then outputs a signal to the activation element 2, which in turn is connected to the processor 6 and an automatic reload of the program and a new one Start of the program in the program memory 10 causes without manual user intervention is necessary.
  • a digital counter 3 (see FIG. 2) are used, which is also like the monitoring element 1 and the activation element 2 with the Unit 4 for input / output of data and the processor 6 in Connection is established and also clocked by a clock 5 becomes.
  • the digital counter 3 now counts with an adjustable counting frequency and adjustable counting interval and is used when the program runs undisturbed over and over again by unit 4 a reset bit, starting from unit 4, reset.
  • the monitoring element shown in FIG. 1 can 1 and activation element 2 also by a monostable Flip-flop 7 can be realized, which consists essentially of a resistor 11 and a capacitor 12 (i.e. RC element) and a Schmitt trigger element 9.
  • a monostable Flip-flop 7 can be realized, which consists essentially of a resistor 11 and a capacitor 12 (i.e. RC element) and a Schmitt trigger element 9.
  • FIG. 3 shows the monostable multivibrator 7 controlled via a driver element 8, and only then, when a signal is sent from the unit 4 to the driver element 8 which indicates that a program is running. Then the monostable multivibrator 7 is triggered and a signal is prevented from being sent to the processor 6, , which means a reload and a new start of the program. In the case of program errors, this will Monoflop no longer triggered, so that a reset is triggered and the program is reloaded.
