Abstract: A hearing aid device is disclosed. The hearing aid device comprises means to improve, augment and/or protect the hearing capability of a user by receiving acoustic signals from the surroundings of the user, generating corresponding audio signals, possibly modifying the audio signals and providing the possibly modified audio signals as audible signals to at least one of the user's ears. The hearing aid device comprises a sensor member for detecting the movement and/or acceleration and/or orientation (or spatial position) of the hearing aid device. The hearing aid device comprises at least two hearing aid microphones and a control unit for determining the position or a deviation from an intended position of the hearing aid device or hearing aid microphones. The hearing aid device is configured to compensate for a possible dislocation of the hearing aid microphones.

Abstract: An adapter for coupling with medical vials has a housing with a center longitudinal axis. The adapter includes first latching portions on an inner circumference for latching to a first closing cover of a first vial, and second latching portions on the inner circumference for latching to a second closing cover of a second vial. The second closing cover has a larger diameter than the first closing cover. The housing has web portions and spring arm portions extending between the web portions and on which the first latching portions are arranged. The housing is elastically deformable from a first state, in which the spring arm portions latch with the first latching cover, into a second state, in which the spring arm portions allow a latching connection between the second latching portions and the second closing cover. The adapter device can be used in infusion therapy.

Abstract: An apparatus for an aircraft includes an electric machine and a gas turbine. The gas turbine includes a compressor, a turbine unit having a high-pressure turbine and a low-pressure turbine, and a combustion chamber. The compressor is connected via a high-pressure shaft to the high-pressure turbine, and the low-pressure turbine is connected via a low-pressure shaft directly to an output shaft of the electric machine. The high-pressure shaft and the low-pressure shaft are rotatable in different directions. The electric machine is operable as a generator and may be operated as a motor to start the gas turbine. The output shaft is connected via a gear box unit and a free-wheel to the high-pressure shaft. The free-wheel separates the connection between the output shaft of the electric machine and the high-pressure shaft in the presence of a torque flow from the high-pressure shaft in a direction of the output shaft.

Abstract: A printing device includes an applicator with which a test fluid is applied onto a recording medium to be printed to, as well as an absorption measurement system with which absorption data are acquired with regard to the absorption rate of the test fluid. The printing device also includes a fuser to fix a print image printed by the printing device. The fuser is adjusted depending on the acquired absorption data so that an optimal and/or desired fixing of print images on the respectively used type of recording medium is produced.

Abstract: In a method for fixing a print image on a recording medium, data is determined for controlling one or more radiation sources to fix the print image. The data can be determined based on a deformation model of the recording medium such that a deformation of the recording medium is reduced or minimized.

Abstract: In a method to determine a negative effect on a surface of an image carrier of a print group, a reflection spectrum is determined of a region of the surface of the image carrier, the reflection spectrum indicating an intensity of light for different wavelengths. The light is reflected from the region of the surface of the image carrier. A reference spectrum is determined for the region of the surface of the image carrier. The reflection spectrum is then compared with the reference spectrum. Depending on the comparison, the determination is made whether a negative effect is present at the region of the surface of the image carrier.

Abstract: A printing arrangement and a printing method for two-sided printing on a recording medium are disclosed, in which conditioning by steam and/or liquid droplets takes place after printing on the first side of the recording medium. Because of the conditioning, damage is avoided to the print image of the first side during subsequent printing on the second side, without the recording medium being impaired by the conditioning.

Abstract: In a method to determine particle mass concentration in a dispersion having particles and fluid, the dispersion in a measurement cell is exposed to an alternating field of variable frequency to set the particles into oscillation to generate sound pressure waves. Amplitudes of the sound pressure waves are measured depending on the frequency so that a maximum amplitude of the sound pressure waves is established and a frequency associated with the amplitude is determined as a resonance frequency of the sound pressure wave. The mass concentration of the particles in the dispersion is established from the resonance frequency.

Abstract: In a device or method to develop charge images generated on a charge image carrier, a rotating applicator moves developer fluid having charged toner particles charged to a predetermined charge and carrier fluid past the charge image carrier. The developer fluid is moved into a developer gap between the applicator and a counter-electrode where it is exposed to an electrical field between the counter-electrode and the applicator. The toner particles of the predetermined charge are moved in a direction of the applicator depending on their charge, uncharged toner particles remaining unaffected and toner particles of opposite charge being repelled. Via a separation electrode protruding into the developer gap, the developer fluid in the developer gap is divided at an exit of the developer gap into a first partial flow adjacent to the application electrode and into a second partial flow adjacent to the counter-electrode where it is discharged.

Abstract: A form-fitting foot covering (10, 34, 44) is provided including a sole portion (14, 36, 46) and a corresponding uppers portion (16, 38, 48) which is designed to be worn in a tightly fitting manner over a user's foot to provide protection and comfort. The inner surface (20) of the foot covering (16, 34, 44) may carry a medicament (22). The foot covering (10, 34, 44) may be integrally formed using a thin, resilient, stretchable resin material such as latex, vinyl or nitrile, and they may be equipped with a laminated resilient gel padding layer (30). Alternately, the uppers portion (38) may be formed of a woven cloth material (40) or a perforate synthetic resin material presenting air holes (52). An optional adhesive (60) may be used to hold the foot covering in place and create a watertight seal.
