  • the comparators detect the voltage on line 55 and provide binary outputs on the microcontroller input lines, 48 A, 48B, and 48C. Any one of the three comparators has a high output whenever the DC input voltage at line 55 is below the reference voltage for that particular comparator, otherwise the output of that particular comparator is zero. Assuming that the threshold voltages increase in steps such that, Vrl ⁇ Vr2 ⁇ Vr3, the output states of the three comparators are related to the voltage V55 at line 55 as follows.

  • An example of circuit values along with logic levels is listed in Table 2 below.
  • First column shows the switch 12 position in upper boom position where the switch is connected to the speaker and in lower position where the switch is down in front of the mouth position.
  • Second column shows the three-position momentary switch state in upper rest position, middle position and in fully down pressed position. Exemplary values and comparator outputs representing the switch 12 and switch 105 combinations are shown in the following columns.

  • information signal refers to a time varying physical quantity representing desired intelligence, often an audible sound or an electrical signal.
  • the term “retrieval” refers to production or reproduction of a stored information signal from the storage medium characteristics.
  • Fig. 2 shows an embodiment where the second position of the push button switch 105 is open. Opening of a line 34 in predetermined pattern by pushing the three-state switch 105 to a second open position sends a system input to the microcontroller.

  • switch 12 state is dependent on the boom position.
  • Stored boom position connects switch 12 to speaker.
  • the boom dependent switch 12 can be designed to change state quickly somewhere in the middle of the upper and lower mouth position. If, for example, user wants to turn the boom in front, the switch 12 keeps the connection to the speaker until the boom is in the middle of the rotation. In this middle position the switch 12 changes the state to the microphone position. This microphone state is kept in all adjustable, in-front-of-the-mouth boom positions.
  • the boom dependent switch 12 can be used instead of using switch 105 to open line 34. User manually toggles the boom backwards from a speaker position or downward from the microphone position to a open state and back.
  • Receiving of an external messages can change state of the system.
  • microcontroller alerts user through speaker and changes to designated state.
  • system input signals are changed to control the incoming message.
  • Fig. 8 when a telephone call is received and alarm signal is heard while listening to stereophonic music through speakers, the call can be forwarded to e.g. an answering machine 210 by a click 208 without interrupting music listening.
  • a click which, for example in radio listening state signals microcontroller to scan station up, is temporarily used to control the telephone instead.
  • Fig. 2 shows an alternative configuration with closed second, middle state of switch 105. No system inputs given or response signal is heard when the line 34 is opened.
  • Momentary switch system inputs are given by toggling the switch 105 between first and second state and voice commands are given by pushing the switch to third position
  • the software can be designed to ignore the middle input.
  • the software can be designated to wait for the rest position before responding to any other switch states. The switch is released to the first, rest state after each position. If the software does not sense the rest state, then no action will be taken until the rest state is sensed.

  • Processing of a voice command 248 can have several steps such as analog-to- digital converting followed possibly by e.g. automatic gain control, echo cancellation and voice activity detection in order to present the recognizer with as good a signal as possible.
  • a voice recognition means making a comparison between the voice command and a sample command stored in a memory and a control circuit for executing the command.

Abstract

Système de commande de casque permettant de commander un dispositif pourvu d'un microcontrôleur (49), qui comprend un microphone (16), un premier et un second haut-parleur (17, 18) et un interrupteur (12) actionné par l'utilisateur. L'interrupteur désactive sélectivement, dans un premier état, le premier haut-parleur (17) ou, dans un second état, le microphone (16). Un interrupteur monostable (105) crée des modèles de commutation momentanée entre d'une part un premier, un deuxième et un troisième état, et d'autre part au moins un autre état. Un détecteur (42) d'interrupteur comprend une pluralité de comparateurs (46A, B, C), qui permettent de mettre en oeuvre une logique à seuil et de générer un signal indiquant l'état de l'interrupteur (12) actionné par l'utilisateur et celui de l'interrupteur monostable (105). Un microcontrôleur (49) réagissant au détecteur (42), qui comporte un moyen permettant de distinguer les différents modèles de commutation de l'interrupteur monostable (105), lance la fonction correspondante en fonction du modèle de commutation momentanée, de l'état de l'interrupteur (12) actionné par l'utilisateur et du mode de fonctionnement actuel.
