A throttle control apparatus includes a throttle control sleeve rotatably mounted on a handlebar of a vehicle, a throttle control housing fixed to the handlebar, and a throttle sensor unit housed in the throttle control housing. The attachment member comprises a cranial zone having a first radial strength, a caudal zone having a second radial strength, and an intermediate zone having multiple joining longitudinal struts located between and connecting the cranial and caudal zones. A label is assigned to one or more of a plurality of segments of the text such that each of the one or more of the plurality of segments of the text is classified as temporal data in one of a plurality of classes of temporal data. The product selling entity that corresponds to the printer identifier may be determined. The coupling movably engages the first flange to form a cavity between the coupling and the flange. Without any increase in circuit complexity or clock speed, this apparatus can reproduce streams in at least two formats, in which the ratios of the amounts of encoded signal data and of the amounts of calculation required for decoding for the video and the audio are very different.
