摘要:
An implanted microphone is provided that has reduced sensitivity to vibration and attendant acceleration forces. In this regard, the microphone differentiates between the desirable and undesirable components of a transcutaneously received signal. More specifically, the present invention utilizes an output that is indicative of acceleration forces acting on the implanted microphone (e.g., an acceleration signal) to counteract and/or cancel the effects of acceleration induced pressures in an output signal of a microphone diaphragm. This may be done in a variety of ways, including but not limited to, pneumatically, mechanically, electrical analog, or digitally, or combinations thereof. In one arrangement, the generated output may be filtered to match the an acceleration response of the output signal of the microphone diaphragm such that upon removal of the motion signal from the microphone output, the remaining signal is an acoustic signal.

An electrophysiological measurement method and system is provided for positioning an implantable transducer of a hearing instrument relative to a middle ear component or inner ear of a patient. The method and system employ electrophysiological measurement signals obtained in response to test signals applied to an implanted transducer. In one embodiment, the electrophysiological measurements are obtained by an electrocochleography measurement device that measures the cochlear summating potential and/or action potential responsive to test signals applied to an implanted transducer. In another embodiment, an auditory brainstem response measurement device is utilized to obtain electrical potential measurement signals responsive to test signals applied to an implanted transducer.

Methods for assessing a position of an actuator of an implantable hearing aid transducer relative to an auditory component of a patient. According to one aspect of the invention, an implantable hearing aid transducer is located in proximity to the auditory component of the patient. A test signal is provided to the patient to stimulate the auditory component and generate an acoustic response in the ear canal of the patient. The acoustic response is detected and utilized to assess the position of the actuator of the transducer relative to the auditory component.

Exterior rearview mirror for vehicles, preferably for motor vehicles. The exterior rearview mirror has a mirror base, and a mirror body, which can be folded relative to the mirror base and which has a housing. The housing of the mirror body is approximately rectangular when viewed from the side. It is connected to the laterally projecting part of the mirror base in the corner region of the housing. In order to design the exterior rearview mirror such that it is problem-free in use, the housing transitions through a narrow section into a connecting part to the mirror base. The mirror body is mounted on the mirror base by means of this connecting part. Consequently, the overall height of the mirror base can be kept very small. The narrow section of the mirror body prevents wind noises from occurring, since the slip stream can easily flow past the narrow section without catching on parts of the exterior rearview mirror. The exterior rearview mirror has a favorable aerodynamic design, and has a light and small appearance because of the narrow section.

A display or illumination element for motor vehicles has at least one light guide for receiving and guiding light beams emitted by a light source. The at least one light guide has at least one reflection element and at least one surface transparent for the light beams. The at least one reflection element is positioned in a path of the light beams and is configured to reflect the light beams to the at least one transparent surface.
