    摘要： Filter cartridges may have a core element formed of a non-filtering, self-supporting non-woven mass of indefinite length continuous synthetic polymeric core fibers, and at least one annular filtration zone layer formed of a mass of non-woven indefinite length continuous synthetic polymeric filtration fibers. The non-woven core element is most preferably formed in situ during filter cartridge manufacturing by melt-blowing synthetic polymeric core fiber streams toward a forming mandrel. The non-woven core element is completely solidified prior to the filtration zone fibers being melt-blown thereon so that the core and filtration fibers are predominantly mechanically interlocked with one another, instead of being melt-bonded thereto. Filter cartridges of predetermined length may be cut from an upstream filter cartridge preform of indefinite length by subjecting the preform to forced cooling air to thereby minimize (if not eliminate entirely) significant filter cartridge shrinkage over time. In addition, a cutter assembly may be mounted laterally of the preform, but is capable of rate-synchronized longitudinal movement with the preform during its cutting operation.

    摘要： A compressor can compress an image by reducing the amount of data while preserving the information. Some compressors use run length coding wherein image data is converted into a series of run length code words. The efficiency of run length coding can be increased with the introduction of differential run length code words. The differential run length code words can augment the original set of run length codes. Differential run length codes vary from current run length codes by encoding runs of differences.

    摘要： The design of an integrated circuit device is simplified by employing reusable modules to avoid or reduce the need to design special purpose glue logic otherwise needed to interconnect the modules. Functional modules comprise interface circuits that are interconnected by buses and operate according to prescribed bus-access protocols. In a preferred embodiments, bus access is arbitrated in an adaptive manner that may be controlled by a principal module in the device. In other embodiments, bus arbitration is not required. The operation of each functional module may be programmed under the control of the principal module.
