Upon acquiring first data transmitted from an outside of a predetermined range in a network, an apparatus stores, in a memory, first information including transmission source and destination addresses of the first data. A metal seal has a first end portion that sealingly engages the first seal surface and a second end portion that sealingly engages the second seal surface. A resource allocation of resource blocks when in the TDMA mode is furthermore such that resource blocks may be allocated to a plurality of remote stations which have overlapping time intervals and disjoint sets of OFDM subcarriers thereby allowing simultaneous communication for the plurality of remote stations within the overlapping time interval. Programmable controls on the machine permit the cleaning functions to be carried out in relation to the position of the machine on the lane. A display device receives the signals from the microprocessor and displays the calculated results to the machine operator.
