An accessory support apparatus for use with a patient support includes a body including a plurality of accessory couplers. In addition, the microphone-including arrangement is supported entirely by the helmet of the rider, and the communication system does not involve any connecting wires which may otherwise extend between any components of the system which are carried by the rider and any components of the system which are carried by the power sports equipment. Since a honeycomb can be directly produced as the cordierite sinter itself, an inexpensive product can be provided through the simplifying the prior-art step of coating the interior of the honeycomb. The vertically separated resonators are supported by standoffs that are fabricated on the substrate, or on a resonator. This data recording method comprises a transfer step of transferring program data recorded in the read only area in a practical form to an external computer, and an execution step of automatically executing the program data in the external computer to record data in the writable area, which can facilitate manufacturing and reduce the possible of destruction or falsification of ROM data. The multiplier unit may form dual products from separate parts of the input data.
