Definitions

  • the invention relates to a digital hearing aid according to the preamble of claim 1 and to circuits for process monitoring of a digital hearing aid according to the preambles of claims 3 and 4. Furthermore, the invention relates to methods for process monitoring of a digital hearing aid according to the preambles of claims 7 and 12.
  • the program required for signal processing is loaded in the processor of the digital hearing device and then executed in a controlled manner via a program counter.
  • malfunctions can occur when the loaded program is running.
  • Such bugs can e.g. due to static discharge processes or strong electromagnetic fields (e.g. in the vicinity of GSM telephones).
  • the user of the hearing aid is now generally forced to switch the hearing aid off and on again and thus to initialize the hearing aid and reload the aborted program.
  • the user of the hearing device may experience considerable and disruptive downtime, during which the user must manually reactivate his or her own hearing device and may even be distracted, so that he is exposed to an increased risk of an accident.
  • the interruption of the signal transmission is perceived by the user as disturbing.
  • the malfunction could also cause harmful levels at the output of the hearing aid if it is not recognized in time.
  • the invention is based on the object of offering a digital hearing aid as well as circuits and methods which avoid a temporary failure of a digital hearing aid in the event of a malfunction in the program sequence.
  • Claim 12 includes advantageous method variants in subclaims 13 - 15 and 16 and 17.
  • the digital hearing aid has on the one hand a monitoring element for ascertaining a failure or a malfunction of the sequence program and, on the other hand, an activation element which causes the sequence program to be automatically restarted in the event of a failure or malfunction of the sequence program.
  • this failure is determined by the monitoring element and, after a signal has been sent to the activation element, the program is automatically restarted and reloaded without manual addition and the user having to react.
  • the hearing aid according to the invention thus has increased ease of use even in the event of a program fault and increases safety when wearing a hearing aid.
  • the monitoring unit not only detects a malfunction of the program sequence, but also monitors fluctuations in the supply voltage and, if the supply voltage drops below an adjustable limit value, also carries out a new loading of the program.
  • the monitoring element and the activation element can be designed as separate components, but also as a combination component.
  • a digital counter is provided which is connected to the unit for input / output of data, a clock generator and the processor of the digital hearing aid.
  • a circuit for process monitoring which has a monostable multivibrator, which is connected to the unit for input / output of data and to the processor.
  • a driver element is provided between the monostable multivibrator and the unit for input / output of data, whereby the monostable multivibrator is indirectly controlled.
  • Claim 6 has a further advantageous embodiment of the circuit according to claim 4 and provides a Schmitt trigger element which is connected downstream of the monostable multivibrator and upstream of the processor.
  • the analog output signal of the monostable multivibrator is discrete 1 "- or O "signals converted to control the processor.
  • the method according to the invention which uses a digital counter, consists of method steps a) - e). During these process steps, the program must be reset periodically if the program is not disturbed Digital counter provided. If a program malfunction occurs, the digital counter is not reset and overflows.
  • the digital counter sends the next step in the method to the processor of the hearing device, as a result of which the program is reloaded into the respective processor memory and the program sequence starts again from the beginning.
  • the (overflowed) digital counter is then reset and, in the following undisturbed program sequence, is automatically and periodically reset again and again by signals integrated in the program sequence.
  • method steps a) - e) according to claim 7 are also carried out if the supply voltage of the hearing aid temporarily falls below a supply voltage limit.
  • the periodic reset of the digital counter in the case of an undisturbed program sequence is advantageously carried out according to claim 11 by a periodic reset signal of the unit for input / output of data or of the processor of the digital hearing aid.
  • the process monitoring method according to the invention uses a monostable multivibrator in its implementation. The latter is triggered periodically during normal program execution, i.e. activated.
  • the monostable multivibrator falls back into its deactivated state in the event of a program error and generates a reset pulse.
  • method embodiments 16 and 17 it is provided in advantageous embodiments to determine the respective causes of the program sequence faults (such as the drop in the supply voltage below a limit value) and to make them visible via information elements.
  • the latter can also be done by importing the respective signals associated with the causes of the malfunction into a (queryable) memory of the processor.
  • FIG. 1 shows a processor 6, which is clocked via a clock generator 5 and which loads the respectively called programs for signal processing into the program memory 10. This processes the signals and forwards signal data to the unit 4 for input / output of data.
  • the latter unit 4 is connected to the processor 6, but also to the monitoring element 1.
  • the monitoring element 1 now detects if a fault occurs when the program loaded in the program memory 10 is running and then emits a signal to the activation element 2, which in turn is connected to the processor 6 and an automatic reloading of the program and a new start of the program in the program memory 10 brings about without the user having to be influenced manually.
  • a digital counter 3 (cf. FIG. 2) is advantageously used, which, like the monitoring element 1 and the activation element 2, is connected to the unit 4 for input / output of data and the processor 6 and is also clocked by a clock 5.
  • the digital counter 3 now counts with an adjustable counting frequency and an adjustable counting interval and is reset in the case of an undisturbed program sequence again and again by a reset bit emitted by unit 4, starting from unit 4.
  • the monitoring element 1 and the activation element 2 shown in FIG. 1 can also be implemented by a monostable multivibrator 7, which essentially consists of a resistor 11 and a capacitor 12 (ie RC element) and a Schmitt trigger element 9.
  • a monostable multivibrator 7 which essentially consists of a resistor 11 and a capacitor 12 (ie RC element) and a Schmitt trigger element 9.
  • the monostable multivibrator 7 is controlled via a driver element 8, and only when a signal is sent from the unit 4 to the driver element 8, which indicates that a program is running.
  • the monostable multivibrator 7 is then triggered and a signal is prevented from being sent to the processor 6, which causes the program to be reloaded and restarted. In the event of program errors, the monoflop is no longer triggered, so that a reset is triggered and the program is reloaded.
