More specifically, compositions and processes for preparing extrudable free-flowing powder blends containing PVC and wood flour (WF) are also provided for preparing foamed or nonfoamed extrudates. The processes provided herein incorporate components which may contain up to a total of 25 weight percent water. Processes for preparing foamed extrudates are also provided wherein a cooling fluid is used to increase the expansion ratio of the foam. Finally provided are composites having an extrudable thermoplastic substrate and at least one capstock layer disposed thereon containing a PVC/WF composition.

Abstract: A system and method for prescribing and/or dispensing ophthalmic lenses for a wearer. The method includes determining at least the wearer's individual visual behavioural patterns in terms of head movement and/or eye movement, processing those patterns with respect to a predetermined relationship between known head movements and/or eye movement characteristics and available ophthalmic lenses, such that the processing categorises wearers into a head movement or eye movement category that can then be used to produce a recommendation for an ophthalmic lens for the wearer. The system includes a transmitter unit (10), receivers on the user (12, 14) providing data to the interface (16). During a test a standard set of frames (18) are used, as are near (20) and intermediate (22) distance reading planes.

Abstract: Personalized video stories are produced. Unfinished stories are first recorded on a video medium with blank segments. Digital sequences are used to complete the segments, for example, by portraying a character with a keyed-out facial area, using the digitized image of a subject to complete the character. An edit list is also prepared to locate the blank segments. The story is sequentially advanced to each segment in accordance with the edit list and, at each segment, the personalized sequence is recorded, thereby completing the story as though the subject is a character in the story. A plurality of different stories may be prerecorded, each substantially completed but including a plurality of unfinished segments. The stories may include animation, for example in the form of cartoons, the personalizes being recorded onto the previously uncompleted tape in such a way that a smooth, visual transition is realized at the start and ending of each segment.

Abstract: Disclosed is a modular worktop, and method of assembly, including a surface member, a front edge, and a backsplash, the components preferably being removably attached to each other. Each of the surface member, front edge, and backsplash may be selected from a predetermined group of decorative surfacing options, resulting in a worktop that is aesthetically pleasing to the consumer or person selecting the components. Additionally, each of the components is sized and configured so as to bring assembly and installation within the skill range of the average consumer. Because the front edge is removably attached, the front edge is changeable at the discretion of the consumer, for example, for aesthetic reasons.

Abstract: A progressive ophthalmic lens element including a lens surface having an upper viewing zone having a surface to achieve a refracting power corresponding to distance vision, a lower viewing zone having a greater surface power than the upper viewing zone to achieve a refracting power corresponding to near vision, and an intermediate zon extending across the lens element having a surface power varying from that of the upper viewing zone to that of the lower viewing zone and including a corridor of relatively low surface astigmatism, the progressive ophthalmic lens element including progressive design elements selected to reduce myopia progression.

Abstract: A system and method for predicting the timing and costs of future service events. A scheduler determines a list of future service events for the product. A simulator simulates each of the listed future service events for the product and predicts the costs associated with the events. The list of the future service events and the total of the predicted costs are aggregated into a prediction that may be used in offering long term service agreements to maintain the product.

Abstract: The present application discloses an innovative improved circuit, in which the long transient at write-to-read transitions is avoided by using a shorting switch to short the inputs of the first amplifier stage together when the read amplifier is activated. This speeds up write-to-read transition. Moreover, since read mode can now be entered more quickly after a power-down condition, this circuit also permits the use of other power-saving tricks to idle the read amplifier momentarily.

Abstract: A progressive ophthalmic lens element including a lens surface having upper viewing zone providing good optical quality at a predetermined low surface power over a large area of vision; said predetermined power being determined by the viewer's distance prescription (R.sub.x) the horizontal fitting position normally being determined by the inter pupillary distance of the wearer, and the vertical fitting position normally being determined by the vertical frame midpoint; a lower viewing zone of higher surface power providing an enhanced range of vision for intermediate or lesser viewing distances; and a corridor of relatively low astigmatism extending therebetween; wherein the contours of mean surface power and/or surface astigmatism within the lower viewing zone, upper viewing zone and corridor are generally symmetric about a vertical lens meridian.

Abstract: An innovative differential amplifier circuit, which can control the midpoint potential of a load which does not itself have any midpoint connection. This is achieved by using a proxy load element in parallel with the primary load. The proxy load is of much higher impedance value than the primary load, and does have a center tap. The potential of the center tap of the mirrored load is used for a feedback connection to a control loop which regulates the output to both the primary load and the proxy load.

Abstract: An innovative disk drive system which provides a regulated bias current to a magnetoresistive read head, and controls the voltage of the magnetoresistive read head terminals so that the CENTER of the resistor is at ground. This halves the peak magnitude of the head-to-disk voltage.

Abstract: An innovative circuit for driving the write head. All of the driving transistors are NPN, and are prevented from saturation. This is achieved by shifting and scaling down the differential drive applied to the pull-up transistors, to drive the pull-down transistors with levels such that the pull-down transistors cannot reach saturation. This provides a very simple circuit in which all four of the drive transistors are NPN, and all are kept out of saturation. Moreover, the peak write current applied to the head is precisely limited.

Abstract: A distinct cultivar of Stokesia plant named `Purple Parasols`, characterized by its vigorous plant growth habit and moderate growth rate; large, showy inflorescences; ray florets that initially are light blue, becoming darker blue, then bluish purple to reddish purple and dark hot pink with further development; numerous inflorescences per plant; and good container, cut flower and garden performance.
