A method is provided for extending the frequency band of an audio signal during a decoding or improvement process. The method includes obtaining the decoded signal in a first frequency band, referred to as a low band. Tonal components and a surround signal are extracted from the signal from the low-band signal, and the tonal components and the surround signal are combined by adaptive mixing using energy-level control factors to obtain an audio signal, referred to as a combined signal. The low-band decoded signal before the extraction step or the combined signal after the combination step are extended over at least one second frequency band which is higher than the first frequency band. Also proved are a frequency-band extension device which implements the described method and a decoder including a device of this type.

The technology describes a stamp and stamp pad for a self-inking stamp, having a housing or a carrying device for a pad for absorbing ink. The carrying device is rectangular in shape, having a base plate with longitudinal surfaces and lateral surfaces moulded thereon. On two surfaces running in parallel handle elements for the lateral gripping of the carrying device are arranged. On the lateral surface a handle element for the lateral gripping and pulling of the carrying device out of a stamp are formed of a plurality of parts displaceable within one another. The handle elements are formed for insertion in a clearance of a lower part of the stamp and do not protrude out of the outer surface of the lower part, so that an upper part of the stamp is displaceable via the clearance with the handle elements inserted in the lower part.

The invention relates to a stamp comprising a telescoping upper and lower part as well as a printing plate holder pivotally disposed in the lower part to accommodate the stamp plate. A retaining device for a stamp pad is associated with the printing plate holder, and in a rest position the printing plate holder is positioned in the range 80° to 135°, preferably at approximately 90° with respect to a contact area. From this rest position the stamp can be displaced into an operating position to produce a stamped imprint via guide means, whereby the printing plate holder is turned about two guide pins, wherein one guide pin is respectively disposed on a side face of the printing plate holder, and the guide pins simultaneously engage in guide slots in the upper and lower part.

In some embodiments, a stamp may include at least one stamping component and one stamping insert. The stamping component may be formed of a top part with a handle element and a bottom part with a cushion-receiving element. The stamping insert may be connected so as to move synchronously via a reversing mechanism having a slide track in the bottom part via an shaft or trunnion to the top part. In the resting position a text plate mounted on the stamping insert may abut against an ink pad soaked with ink in the cushion-receiving element. The stamping insert with the text plate can be shifted by the reversing mechanism into a stamping position. On the ink pad, a protective cover is located on that side on which a handle element is located on a support device of the ink pad. The system including an ink pad and a closure cap.
