The invention relates to a method and a receiver having control logic means for determining a target packet level of a jitter buffer adapted to receive packets with digitized signal samples, which packets are subject to delay jitter, from a packet data network. The apparatus includes a fixing bracket, a moving bracket, and a slide structure. Rotated copies of the address input are subsequently logically combined in accordance with a key to generate a hashing result corresponding to the address input. These include looking at correlation and gain imbalance between antennas, looking at the processing gain resulting from one or more of the receiver processing functions, and looking at the equalization quality of at least two receiver processing functions. It is flexible enough to allow a work piece to be maneuvered past the splash protector during grinding operations. Further, the second process binds the converted closures within the monad to restrict execution of the functions.
