A multi-cylinder reciprocating compressor has a plurality of compression chambers and a plurality of discharge valve devices associated with the respective compression chambers. The first gain module is configured to receive first signals generated based on a plurality of data streams mapped to a plurality of antennas including a first antenna and a second antenna, and to apply a first gain corresponding to the first antenna to the first signals. Spaced apart brackets are coupled to one of the sidewalls. The first message may comprise a first command and an operation input value for a print job at the cartridge, and to process the first message may comprise decreasing the amount of dispensable material. An expansion extractor receives the potential acronym and a processed word list to retrieve the expansion of the potential acronym from that list. The managing apparatus is operable to detect when the vehicle recording device, personal recording device, or any other synced device in range has begun recording and to transmit a communication signal to any synced recording device in range indicating that the recording device should begin recording and to further transmit a time stamp to synced recording devices for corroborating recorded data.
