20090003627 | Hearing apparatus with passive input level-dependent noise reduction - A hearing apparatus and in particular a hearing device is to be provided, in which interference noises are to be reduced however as natural an acoustic image as possible is consequently retained. To this end, a hearing apparatus with a first signal processing channel, into which a noise reduction device is integrated and a second signal processing channel, which has the same input as the first signal processing channel and into which no noise reduction device, but instead a level limitation device is integrated, is proposed. An adding device adds the output signals of both signal processing channels to form an overall output signal. A passive input level-dependent noise reduction can thus be realized, with which quiet signals can be heard again despite the noise reduction. | 01-01-2009 |

20110051943 | METHOD FOR ADJUSTING A HEARING AID AND HEARING AID ADJUSTMENT INSTRUMENT - Optimized hearing aid parameter settings are automatically determined from a multiplicity of data obtained by applying different test methods for testing the auditory perception of a person. Data pertaining to the auditory perception (audiological data) of the user are first obtained by different test methods. The data from the individual tests can be incomplete, inconsistent or untypical, or even erroneous. However, the subsequent combination of where possible all available data in a computational unit affords the possibility of automatically obtaining hearing aid parameter settings by way of which a hearing aid operated thereby compensates the present loss of hearing of the relevant user in an optimized fashion. | 03-03-2011 |

20100204943 | METHOD AND DEVICE FOR THE CALIBRATION OF NETWORK ANALYZERS USING A COMB GENERATOR - A vectorial network analyzer including n test ports. With the connection of several different calibration standards to the test ports, several calibration measurements are implemented. For the calibration, different measurements are implemented. Initially, in n calibration measurements, a comb-generator signal is supplied via a direct connection successively to all n test ports. Using a measuring point at the output of the comb generator and the measuring point associated with the respective test port, phase measurements are implemented at all of the frequencies forming the comb-generator signal. A frequency-dependent phase offset is determined from the phase measurements. Moreover, in at least one measurement, all n test ports are terminated successively in each case using known, input impedances, identical within one measurement, of arbitrary transmission properties, wherein successively, all n test ports are excited using a transmission oscillator successively with all frequencies of the comb-generator signal. | 08-12-2010 |

20140306602 | HIGH-FREQUENCY LAMP AND METHOD FOR OPERATING A HIGH-FREQUENCY LAMP - The invention relates to a high-frequency lamp with a glass bulb and a device for supplying a high-frequency signal. High-frequency lamps known in the prior art either have been limited to a narrow selection of substances in the glass bulb or have relied on a heating process using a spiral-wound filament or the like. The aim of the invention is to provide an inexpensive and more efficient high-frequency lamp. This is to be achieved in particular in that the glass bulb is made, for example from window glass, so as to be heatable by the heat losses of the high-frequency signal in the glass bulb such that even metal halogenides for example can be evaporated without an additional heating process. | 10-16-2014 |
