Abstract: In order to substantially realistically pre-operatively demonstrate to patients having an impaired hearing the effect and sound impression of an least partially implantable hearing system including a first electronic audio signal processing unit, a demonstration device is provided which comprises an electromechanical transducer adapted for being non-invasively coupled from the side of the external auditory canal to at least approximately the center of the tympanic membrane and thus to the end point of the manubrium mallei for producing mechanical vibrations of the tympanic membrane, an electronic audio signal generator unit, and a second electronic audio signal processing unit connected between the audio signal generator unit and the electromechanical transducer for driving the electromechanical transducer, wherein the second audio signal processing unit corresponds to or simulates the first electronic audio signal processing unit.

Abstract: An at least partially implantable system for rehabilitation of a hearing disorder with at least one sensor for picking up an acoustic signal and converting the acoustic signal into corresponding electrical signals, an electronic signal processing unit for audio signal processing and amplification, an electrical power supply unit which supplies energy to individual components of the system, and an output-side electromechanical transducer arrangement which consists of at least two independent and spatially separate transducers for stimulation of the inner ear. In conformity with the invention, the output-side electromechanical transducers are designed for stimulation of the fluid-filled inner ear spaces of the damaged inner ear and the signal processing unit comprises driving signal processing electronics which electrically controls each of the transducers such that a traveling wave configuration is formed on the basilar membrane of the damaged inner ear.

Abstract: A system for rehabilitation of a hearing disorder which comprises at least one acoustic sensor for picking up an acoustic signal and converting it into an electrical audio signal, an electronic signal processing unit for audio signal processing and amplification, an electrical power supply unit which supplies individual components of the system with current, and an actuator arrangement which is provided with one or more electroacoustic, electromechanical or purely electrical output-side actuators or any combination of these actuators for stimulation of damaged hearing, wherein the signal processing unit has a speech analysis and recognition module and a speech synthesis module.

Abstract: An exterior rearview mirror for a motor vehicle has a mirror head having a housing and a mirror pane mounted in the housing. The housing has a light window. At least one light source is mounted in the housing and positioned behind the light window. The light window consists at least partially of a light guide material in order to ensure complete and uniform illumination.

Abstract: The invention relates to a process for obtaining data on hearing quality by measuring distortion products of otoacoustical emissions (DPOAE) in which two primary tones with the frequencies f.sub.1, and f.sub.2 >f.sub.1 and sound pressure levels L.sub.1 and L.sub.2 and at least one sound event having proportions of the frequency f.sub.3 and the sound pressure level L.sub.3 are applied as stimuli to the hearing organ and at least one distortion product of the defined frequency is determined, where the value of f.sub.3 is close to the frequency of the distortion product.

Abstract: A housing is provided that has a receiving body for at least one optical sensing device and at least one hollow and air-tight window body for allowing passage of signals to and from the sensing device. The hollow and air-tight window body eliminates condensation on the window through which the signals of the sensing device have to pass and thus improves operation of the sensing device.

Abstract: An exterior rearview mirror for motor vehicles has a housing and a mirror pane pivotably supported in the housing. A light source is mounted in the housing. The housing has an outlet opening through which light emitted by the light source exits the housing. A light guide at least partially fills the outlet opening and is connected within the interior of the housing to the light source.

Abstract: An exterior rearview mirror for a motor vehicle has a mirror support and a mirror housing connected with a first end to the mirror support. The mirror housing has a holder for a mirror pane. A turn signal light is positioned in the mirror housing. At least one first receiver for receiving remote control signals is also positioned within the mirror housing.

Abstract: An interior rearview mirror for a motorized vehicle has a mirror housing with a mirror member and a mirror support connected to the mirror housing. At least one sensor for sensing solar radiation entering the interior of the motorized vehicle through the windshield is provided. The sensor is coupled to the control unit of an air conditioning device of the motorized vehicle.

Abstract: A distance sensing device for a motor vehicle, positioned at the rear of the motor vehicle, for sensing a distance to an obstacle to the rear of the motor vehicle, has a brake light unit positioned in the interior of the motor vehicle at the rear window. At least one sensor for sensing the distance is provided. An optical display unit located within the brake light unit is provided, and the at least one sensor is connected to the optical display unit.

Abstract: A control-motion transmission assembly in the heating, ventilating and air conditioning system of an automotive vehicle comprises a housing, an actuator lever slidably mounted to the housing, and a secondary or setting lever pivotably fastened at one end to an inner end of the actuator lever. Another end of the setting lever is linked to a guide pin and to one end of a Bowden cable wire. The guide pin is guided in a slot in the housing, while an end of the Bowden wire opposite the setting lever is connected to an operating mechanism of the heating, ventilating and air conditioning system. The Bowden cable has a sheath pivotably fastened to the housing.

Abstract: A web or band is attached to the sliding actuator or lever of a slider control at the control panel of an automotive vehicle to prevent the passage of light and dust through a slot in the control panel traversed by the actuator. The ends of the web may be free or, alternatively, attached to the actuator to form an endless or continuous band.

Abstract: At a slot in a control panel of an automotive vehicle, the slot traversed by a slidable actuating lever for controlling the operating state of a heating and ventilating or air conditioning system of an automotive vehicle, an elongate web is disposed parallel and proximate to the slot for preventing the passage of light and dust. The web covers the slot, is attached at its ends to a control panel plate and traverses an opening in the lever.
