Abstract: A cochlear implant includes a sealed housing containing electronics for at least stimulation or collection of data and at least one antenna for communicating with an external device and a magnet configured to hold the external device in proximity to the sealed housing. The sealed housing includes an upper cover being closest to the skin when the device is implanted, and a lower cover that is hermetically connected to the upper cover. The lower cover includes an elevated region, a recessed region, and at least one feedthrough element formed in the recessed region of the lower cover. The recessed region provides space for a lead to connect to the feedthrough element and protects it from shock and other environmental risks.

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: The invention relates to a portable pump device and a cartridge therefore. The cartridge comprises a first reservoir for a flowable drug provided in combination with a second reservoir comprising a pump liquid, a pump chamber being associated with the first reservoir and adapted to receive the pump liquid in order to expel drug from the first reservoir. In a first aspect, the reservoirs of the system may be provided as a disposable cartridge unit to be combined with a further unit to form an delivery device, the delivery device as a whole comprising the pump means for pumping the pump liquid from the second reservoir to the pump chamber, control means for controlling the action of the pump means, and an energy reservoir for energizing the pump means as well as the control means, however, one or more of these components may be incorporated in the disposable cartridge.

Abstract: A hearing prosthesis is disclosed with comprises memory means for storing charging control information associated with charging of a rechargeable battery cell that functions as a power source for the hearing prosthesis. Also, a rechargeable hearing aid system is disclosed which comprises a common communication interface adapted to transmit charging control information from the hearing prosthesis to the charger so as to allow the charger to adapt its charging parameters to a variety of different types of rechargeable batteries.

Abstract: A device for injecting preparations is controlled by a sealed circuit block (10) containing integrated sensors (17, 21, 22, 23 24) which monitors selected parameters. Two pairs of integrated Hall elements (21, 23 and 22, 24) monitors movements relative to a sine formed magnetic field presented along the perimeter of a multipoled magnetized ring (7). The Hall elements in each pair are displaced 180° magnetically relative to each other and the two pairs of Hall elements are displaced 90° magnetically from each other. Each pair is coupled to a differential amplifier (25, 26) to provide a cosine and a sine signal, respectively. The sine signal is divided by the cosine signal to create a tangent signal as an entrance to a table showing the angle of the movement.

Abstract: The present invention relates to flow restrictors suitable for the controlled transfer of fluid from a first compartment to a second compartment. More specifically, the invention relates to a safety arrangement reducing the risks associated with diminished flow resistance through the flow restrictor. In a first aspect the present invention provides a flow restrictor comprising a flow-restricting channel formed between at least a first member and a second member arranged in contact with each other, the flow channel being arranged to form at least one generally U-formed portion with a pair of opposed first and second channel portions, and with a safety channel arranged between the opposed first and second channel portions. The safety channel provides a fluid communication with an exterior space relative to the flow restrictor.
