Abstract:
A decision-making method suitable for production planning in an uncertain demand environment. To this end, the method comprises combining an implosion technology with a scenario-based analysis, thus manifesting, a sui generis capability which preserves the advantages and benefits of each of its subsumed aspects.

Abstract:
A method for determining procurement for parts (P) in a production system having constraints comprising at least one of constrained resources (r.sub.i) and known maximum demands (d.sub.j). The method comprises two steps. Step 1 includes constructing a production planning decision space comprising independent sets of hyperplanes defined by decision variables (q.sub.j) corresponding to product quantities for products (j). The constructing step subsumes steps of expressing a potential usage of part (p) as a linear combination of production quantities (q.sub.j) based on bill of material usage rules; limiting the production quantities (q.sub.j) so that each is less than or equal to the maximum demand quantity (d.sub.j); and limiting the production quantities (q.sub.i) so that the usage of each resource (r) is based on bill of material and bill of capacity usage rates less than or equal to the availability of that resource. For each part p, the second step includes locating a region in the decision space corresponding to a high level of usage of part (p).
Abstract:
An absorbent, flushable, bio-degradable, and medically-safe nonwoven fabric suitable for use as wraps, wipes, absorbent pads, etc., is composed of from 2% to 10% by weight of untreated, water-soluble polyvinyl alcohol (PVA) fibers that are heat-bonded to a matrix of absorbent fibers. The use of PVA fibers in low amounts provides softness, while sufficient wet strength is provided by heat bonding the PVA fibers completely to the other fibers in a two-stage heating process. The resulting nonwoven fabric has a high wet-to-dry tensile strength ratio, good drape softness, and high fluid absorptive capacity. In a method for producing the nonwoven fabric, the PVA fibers are blended with the absorbent fibers, the blended fibers are carded onto a moving web, sufficient water is added to wet the PVA fibers while maintaining web integrity, then the web is heated in two stages, the first with heating cylinders at 40.degree. C. to 80.degree. C., then the second with heating cylinders of 60.degree. C. to 100.degree. C. The fiber web may also be hydroentangled and patterned for enhanced strength and textural properties.

Abstract:
Methods and systems have been provided for communicating digital voice data. According to various embodiments of the invention, a user interface is provided at a network device in the presence of DSP resources. Selection is made by the user interface about whether to use the DSP resources. Based on the selection, the digital voice data is communicated. Selection of bypassing a DSP resource is made by default if no DSP resources are present.
Abstract:
The development port or Debug port of a microprocessor on an intelligent daughterboard is used for downloading code or configuration information from a motherboard for use in boot-up. In various aspects, the code or configuration information can include information used for configuring a port, other than the development port, and/or for configuring a memory controller, such as for a daughterboard DRAM. Use of the Debug port makes it possible to reduce or eliminate the need for storing boot-up code or configuration information on a daughterboard ROM, or other non-volatile memory, thus reducing cost and space requirements, power consumption and the like.
Abstract:
A nonwoven fabric with UV stability and flame retardancy having at least one fabric layer. The fabric layer is made of a base resin, preferably polyolefinic, and a non-halogenated melt processable compound that is selected from the group consisting of N-alkyoxy amines and are combined into a homogeneous blend which is then either spunbonded or meltblown to form the fabric layer. A melt processable fluorochemical additive may also be combined into the homogeneous blend to provide liquid barrier properties to the fabric layer.
Abstract:
An apertured nonwoven laminate is produced by a thermal aperturing process by calendaring a carded web of fibers with a polymeric sheet having a lower melting temperature and a property of shrinking under application of heat and pressure so as to bond to the carded fibers and simultaneously pull back the carded fibers away from the calendering points to generate apertures through the nonwoven laminate. In a preferred apertured nonwoven product for baby wipes, a tri-laminate is formed with top and bottom layers containing polypropylene fibers or fiber blend with rayon fibers, and a middle (polymeric) layer of linear low density polyethylene (LLDPE) film material. The baby wipe product provides a significant cost advantage and an improved aesthetic appearance over conventional products. In a preferred apertured nonwoven product for coverstock for sanitary napkins, a film-fiber bi-laminate is formed with a high-open-area apertured top layer of LLDPE film material and a partially-apertured bottom layer including high tenacity, low elongation polypropylene fibers. An engraved calendar roll is used at the bottom side, while a cooler, smooth roll is used at the top side. The resulting bi-laminate has an apertured, smooth, and quilted appearance on the top side, and the bottom side is resilient and fibrous and acts as an excellent acquisition and distribution layer for the coverstock with low re-wet properties.
