Polymers comprising recurring units of formula are provided wherein R1 is a straight, branched or cyclic divalent C1-20 hydrocarbon group or a bridged cyclic hydrocarbon group, R is hydrogen atom or an acid labile group, 0m3, 0n3 and 0mn6. From this position, the module can be easily and readily attached to the manifold. A system and method in another embodiment includes a first bar code reading device configured to initiate a command to print a bar code symbol which when read by a second bar code reading device can cause the second bar code reading device to operate in the manner of the first bar code reading device. The linear phase-B, cubic spline IFIR filter requires significantly fewer hardware components than traditional FIR filters and is ideally suited for implementation using Very Large Scale Integration technology.
