In some embodiments, a stamp comprising at least one stamping component and one stamping insert with a mounted band unit. The stamping component may comprise a top part and a bottom part with a cushion-receiving element. The mounted band unit may be connected so as to move synchronously via a reversing mechanism in the bottom part to the top part. In the resting position a text plate mounted on the stamping insert and a stamping area of the mounted band unit may abut against an ink pad soaked with ink in the cushion-receiving element. During a stamping process for producing a stamp impression the stamping insert can be shifted via the reversing mechanism into a stamping position. On the stamping insert, a height adjustment element for the mounted band unit and/or a text plate carrier may be provided.

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.

A system for printing PSA on a substrate includes a rigid support structure. The system also includes a plurality of dispensing heads disposed within the rigid support structure and configured to deposit PSA solution on the substrate in response to applied pressure. Each dispensing head of the plurality of dispensing heads includes a support structure and a wicking structure disposed within the support structure and configured to hold the PSA solution, wherein the wicking structure is configured to deposit the PSA solution in a desired shape on the substrate upon contact with the substrate.

A marking device that targets a fastened member and a fastening member (5,6), the marking device comprising; a housing that covers the fastening member (5, 6); and a marking member that is coupled to the housing via a support shaft (30) and is swingable toward the fastening member (5, 6),
characterized in that when a vector having, as a start point, a marked corner part (MC1) and having the swing center (31) as an end point at is a first vector (V1a), and a vector having the marked corner part (MC1) as a start point, and is directed in a direction orthogonal to a central axis (C) of the fastening member (5) and away from the fastening member (5, 6) is a second vector (V2a), an angle (1) formed by these two vectors (V1a, V2a) is equal to or greater than 90 degrees and less than 180 degrees.
