  • Patent number: 6757300
    Abstract: Disclosed is a method and apparatus for inserting a data signal into an audio signal to provide a tagged signal. The method includes removing a band of frequencies centred at a predetermined notch frequency from the audio signal, spectrally shaping the data signal so that it takes on the precise shape and magnitude of the envelope of the audio signal at the removed band, and inserting the shaped data signal into the removed band of the audio signal. The method may be used to identify an audio segment or it may be used to encode the audio signal with other desired data. The method of the invention provides for the data signal to be virtually inaudible to the listener of the audio segment yet robust enough to survive severe audio signal processing.

  • Patent number: 4951062
    Abstract: A paper transport mechanism for grasping paper between a pressure roller and a drive shaft. The pressure roller moves from a retracted position to a force applying position and is supported by a housing which includes a depending underlying support carriage cantilevered from the housing and oriented to oppose the downwardly extending force of the pressure roller. Damping within the housing offsets vibrations generated between the drive shaft and the pressure roller.

  • Patent number: 4355938
    Abstract: An automatic work piece changer for a milling machine and the like is described. In the work piece changer there is provided a work piece hopper (2) for storing a plurality of work pieces to be movable, a carriage assembly (3) for removing work pieces from the hopper (2) to a work station where they are machined, a clamping assembly (6) for holding each of the work pieces in the work station so as to prevent their movement during the machining thereof and an ejecting assembly (60) for ejecting machined work pieces from the changer after they are machined. Operation of the work piece changer is controlled by signals received from the milling machine in a conventional manner.
