The invention relates to an apparatus for mobile application, including a frequency spectrum generator for generating a frequency spectrum of radio waves at a current position of the apparatus and a classifier for classifying the frequency spectrum such that the frequency spectrum is assigned to one of at least two classes.

Apparatus for mobile application and frequency spectrum generator

A hearing aid apparatus contains a housing having a housing face. The housing face is directed outwardly when the hearing aid apparatus is being worn. The hearing aid apparatus further has an antenna and a transmitter and/or receiver for electromagnetic waves disposed in the housing. The transmitter and/or receiver is coupled to the antenna element. A grip element is disposed on the housing face of the housing, and the antenna is integrated at least in part in the grip element.

Hearing aid apparatus and hearing aid device

A first aspect of the invention relates to an apparatus for mobile application, including a frequency spectrum generator for generating a frequency spectrum of radio waves at a current position of the apparatus and a classifier for classifying the frequency spectrum such that the frequency spectrum is assigned to one of at least two classes. A second aspect of the invention relates to a frequency spectrum generator with a tunable local oscillator, with a downmixer for downmixing a received antenna signal with the local oscillator signal for obtaining a downmixed signal, with a filter for filtering out a mirror-frequency portion in the downmixed signal, with a signal level detector for detecting a signal level of the downmixed signal at an intermediate frequency and with a control for sequentially controlling the local oscillator and the signal level detector to sample a frequency spectrum of the antenna signal.

A hearing aid includes a hearing aid housing and an antenna device constructed to receive and/or transmit electromagnetic waves having a predetermined wavelength lambda. The antenna device has a frame incorporated in the hearing aid housing for holding assemblies of the hearing aid and the frame has an electrically conductive structure being an integral part of the frame. A method for producing a hearing aid includes patterning a surface of the frame, applying an electrically conductive layer to the surface of the frame and incorporating the frame into the hearing aid housing.

Hearing aid and method for producing a hearing aid

A hearing aid device has an antenna device. The antenna device is configured to receive and/or transmit electromagnetic waves of a predetermined wavelength lambda. The antenna device has an energy coupling device which is configured to supply or to draw electrical energy to or from the antenna device. The antenna device has a first conductor and a second conductor, which are in energy exchange with the energy coupling device, extend away from the energy coupling device in different directions and are arranged a short distance from a third conductor. A first ohmic connection between the first conductor and the third conductor and a second ohmic connection between the second conductor and the third conductor are arranged at a predefined distance from the energy coupling device.

Hearing aid device having a folded dipole

A device and method for determining a distance and/or orientation of a movable object includes a transmitter that is located on the object and a receiver. One of the transmitter and the receiver has an antenna having a known polarization plane. The other of the transmitter and the receiver has a counterclockwise circular polarized antenna and a clockwise circular polarized antenna.

Device and method for determining the distance and/or orientation of a moveable object

An antenna comprises a first antenna element, which has a first helix, and a second antenna element, which has a second helix. The first and the second antenna elements each have a feed point at an outer end of the corresponding helix and an open end at an inner end of the corresponding helix. A symmetrical helix antenna according to the invention can be integrated in a comparatively simple manner in an existing system, for example in a hearing aid. By integrating the antenna in a plastic housing, the antenna cannot be seen at all from the outside. The antenna is comparatively small in relation to conventional antennas.
