Abstract: Data of a predetermined volume portion of an object under examination is captured by an x-ray system that includes an x-ray source and a detector. The x-ray source is activated to generate x-rays that emerge from the x-ray source, radiate through the volume portion, and after radiating through, impinge on the detector. X-rays impinging on the detector are captured pixel by pixel, in order to capture the data of the predetermined volume portion. With the pixel-by-pixel capture, only a subset of all the pixels of the detector is evaluated.

Abstract: Stereo projections of breast tissue to be examined are dynamically generated with the aid of an x-ray projection machine. An x-ray source of the x-ray projection machine is moved to a start position. Thereupon, an x-ray projection recording is started at the start position and the x-ray projection recording is performed while the x-ray source moves to a finish position. The position of the x-ray focus is updated during the x-ray projection recording so that a change in position of the x-ray focus is compensated for at least in part, preferably in full. The x-ray projection recording is terminated when the finish position is reached. A method for ascertaining a position of breast tissue to be examined and an automated method for planning a biopsy are described. An x-ray source control device and an automated stereotactic biopsy machine are described.

Abstract: A hearing instrument system with a rechargeable battery or accumulator is optimized for everyday use, in particular for EOL detection, and the performance and service life of the accumulator. A hearing instrument, an accumulator system, and a charging system each have an energy transfer interface and a communication interface. The energy transfer interface and communication interface on the accumulator side can establish an energy transfer link and/or communication link on the charge and hearing instrument side. The accumulator system provides energy to the hearing instrument and transmits state of charge information generated by an accumulator control facility to the hearing instrument by way of the respective communication link. The transmission of the state of charge information enables a reliable state of charge detection in the case of batteries, whose state of charge cannot be identified on their voltage, for instance Li-ion systems with closed-loop controlled voltage.

Abstract: With a hearing aid device, the problem arises of having to match the output power and/or the frequency response of the hearing aid device to the level of hearing impairment of the patient as precisely as possible. In such cases allowance must be made for the noise level, which is a function of the technology used, to be kept as low as possible and for the signal-to-noise level to be as great as possible. A switching arrangement and/or a hearing aid device and method are provided in which the power amplifier is embodied with at least two output stages. The outputs of the individual output stages can be connected in parallel by means of a controllable switching facility. A simple adjustment of the output power and/or frequency response can be achieved in this way by simply connecting a corresponding number of output stages in parallel.

Abstract: The adjustment of a hearing device with regard to a current feedback path is to be designed in a more user-friendly manner. For this purpose, provision is made for hearing aid equipment, in particular a hearing device or a non-programmable device such as a headset, including a measuring device for measuring a feedback path and an operating facility for operating the hearing aid equipment by the wearer. The operating facility allows a measurement cycle to be activated to determine at least one characteristic of the feedback path. The hearing aid wearer can thus make adjustments themselves in terms of the feedback path and therefore does not have to rely on an acoustician.

Abstract: A communications system is configured to reduce the risk of feedback artifacts and contains a telephone device and a listening device. Accordingly, the communication system is thus provided, in which the signal processing in the telephone device is tuned to the listening device and the listening device is configured to process the voice and data signal inversely to the signal processing. Before the acoustic signal is transmitted from the telephone to the listening device, a frequency compression can thus be carried out, and in the listening device an inverse frequency compression can be carried out. This reduces feedback artifacts.

Abstract: Feedback whistle in hearing devices is intended to be able to be suppressed without loss of output of the useful signal. To this end, it is provided to establish or predetermine a frequency range which is susceptible to feedback. From an input signal which has a spectral component in the frequency range susceptible to feedback, a predeterminable component is substituted with a synthetic signal. Mixing-in a synthetic signal is also possibly used to widen the spectrum of an input signal, which is limited.

Abstract: In hearing devices, more particularly in hearing aids, it is desirable to be able to design an earpiece for generating sound in the audible range which is as small as possible. Such an earpiece can then be worn comfortably on an ear or in an auditory canal. A sound transducer for the hearing device disclosed here may be formed as a micro-electromechanical system and the transducer enables generation of an acoustic signal with little distortion. Provision is made for a hearing device with a sound transducer, which has a field generation apparatus for generating an electric or magnetic field and an emission apparatus for generating sound. Here, the emission apparatus has a multiplicity of fingers that are penetrated by the field of the field generation apparatus, wherein the shape of the fingers can be changed by means of the field of the field generation apparatus in order to generate the sound.

Abstract: A hearing aid is provided. The hearing aid has a one- or multi-part carrying hook. The one- or multi-part carrying hook has a tip for connection to a sound tube, the tip being connected integrally to a damper extending across the internal cross-section of the tip, the damper preferably being designed as a membrane.

Abstract: A hearing apparatus includes a charging contact being movable relative to an accumulator and being electrically conductively connected to the accumulator in a first position and less effectively conductively connected thereto in a second position. A spring-elastic element engages with the charging contact in order to push the charging contact into the second position with a predetermined force, so that the charging contact can only be pushed into the first position by overcoming the predetermined force. As a result, the charging contact configuration obtains a switching function, so that electro-corrosion on the charging contacts can be prevented. Therefore, charging an accumulator of a hearing apparatus and in particular of a hearing device using a direct conductive contact is possible, with zero potential of the charging contacts which are accessible from the outside being ensured during normal operation of the hearing apparatus.

Abstract: The size of measuring boxes for hearing apparatuses and in particular for hearing devices is to be reduced, with the efficiency of the measuring box in respect of attenuating interference noises being maintained or improved. A measuring box is thus proposed, which comprises an interference signal recording facility for recording an interference signal. Furthermore, provision is made in the measuring box for a signal generating facility to generate a compensation signal which is phase-opposed to the recorded interference signal, so that the interference signal can be compensated for by the compensation signal. The interference noise attenuation is thus achieved here by an electronic active part, so that the quality demands on the measurement space can be reduced and its size thereby decreased as well.
