Illustrated and described embodiments are broadly directed to novel systems and methods for generating a composite video signal from a plurality of independent video signals. Initially, a lessee pickup code is communicated from a borrowing party to an owning party upon exchanging the tangible item between the owning party and the borrowing party. Two data portions are characterized by similar expected IO activity if a distance between activity vectors characterizing respective statistical segments matches a similarity criterion. Corresponding to the gain setting set by adjusting the variable resistor, capacitance values of the variable capacitors can be adjusted to provide improved frequency characteristics of the variable gain amplifier. In the case that the compressor is or has been already switched on whilst pre-setting the permissible compressor temperature TG1 and during this switched-on period or during a subsequent cooling phase a request is made to achieve the second operating state BZ2, the compressor continues to be operated or is switched back on whilst pre-setting the permissible higher compressor temperature TG2.
