20100090908 | ANTENNA OF PARALLEL-RING TYPE - The present invention relates to a parallel-ring type antenna which is reduced in entire physical length, and has a wider bandwidth and a more excellent return loss, while having the same resonant point, by changing a loading portion of a retractable antenna employing a top-loading method that can easily secure the physical length of the antenna. Further, characteristics electrically similar to those of a helical antenna can be achieved by applying the parallel-ring type to the loading portion of the monopole termination. In addition, the entire length of an antenna can be reduced, while accomplishing the same resonance as that of the helical antenna, by employing a change in return loss according to a change in the thickness of the parallel ring, the distance between the rings, the diameter of the ring, and/or the length of the loading portion. | 04-15-2010 |

20090129616 | Hearing Device Having a Mechanical Display Element - A hearing device for wearing in or on the ear and for outputting a sound to the ear includes an electronic unit and a display unit for displaying a state of the electronic unit and for easily detecting the state of a hearing device such as a hearing aid while using as little energy as possible. The display unit has a display element that can be moved mechanically, depending on the state of the electronic unit, into a position specific to the state. It is possible to use the display unit to display the switched-on state and the switched-off state of a hearing aid. In particular, it is advantageous to couple the display element mechanically to a battery compartment when the battery compartment is used to switch the hearing aid or the hearing device on and off. However, the display element can also be moved by magnetic or electrical forces. | 05-21-2009 |
20090202084 | Method and Apparatus for Monitoring a Hearing Aid - A hearing aid contains a microphone detecting an acoustic input signal and converts it to an electrical output signal, a receiver producing an acoustic output signal being dependent on an electrical output signal of the microphone, and a transmitter transmitting a monitoring signal, which is dependent on the electrical output signal. A transceiver contains a receiver for receiving the monitoring signal, and a signal processing device for processing the monitoring signal. The signal processing device processes the monitoring signal to produce an indication signal which is acoustically restricted with respect to the monitoring signal such that it simulates a restricted hearing capability of a person, or which indicates an operating/signal state of the hearing aid. The transmission of the monitoring signal to the transceiver and the processing to form the indication signal provides information about the state of the hearing aid for monitoring of the hearing aid. | 08-13-2009 |
20120002831 | ELECTRICAL HEARING AID ADAPTER - An electrical hearing aid adapter is provided. The electrical hearing aid adapter may be configured to transfer programming data to a hearing aid having a first end portion formed in such a manner that it corresponds to the shape of a battery compartment receiving chamber being configured to receive a hearing aid battery compartment. The electrical hearing adapter may further include an interface configured to receive programming data and to transfer received programming data to an electrical contact portion arranged on the first end portion. The first electrical contact portion may be arranged such that it electrically contacts to a second electrical contact portion placed in the battery compartment receiving chamber, when the first end portion is inserted into the battery compartment receiving chamber. | 01-05-2012 |
