  • System for wireless information transmission between two different rooms
    Patent number: 5625883
    Abstract: For audio and/or video or control signal transmission between two rooms in, for example, a house, inductive and/or capacitive transmitters and receivers are used which are installed on opposite sides of the partition or wall that separates the rooms.

  • Method of and device for detecting pulsatory interference signals in a sound signal
    Patent number: 5586192
    Abstract: For detecting pulsatory interference in a sampled audio signal, the value of a given signal sample is compared with the values of previous as well as subsequent signal samples within a selected time window. If the given sample, multiplied by a selected attenuation factor, exceeds a certain percentage of all such samples, that identifies it as an interference pulse. It can then be replaced by an interpolated sample value derived from adjoining samples over a selected interval of the signal.
