Abstract: An electrophoretic medium comprises a plurality of particles suspended in a suspending fluid, the particles being capable of moving through the fluid upon application of an electric field to the medium, the fluid having dissolved or dispersed therein a polymer having a number average molecular weight in excess of about 20,000, the polymer being essentially non-absorbing on the particles. The polymer improves the bistability of the display (i.e., the period for which a written image persist without the display being refreshed) but does not greatly increase the viscosity of the suspending fluid, thus keeping the switching time of the display within reasonable limits. The medium may be encapsulated, or may be in the form a polymer-dispersed electrophoretic medium.

Abstract: A device for predistorting a transmission signal to be transmitted over a nonlinear transmission path comprises an estimator for determining an error signal depending on the transmission signal and a previously registered transfer characteristic of the nonlinear transmission path. The error signal represents an estimate of an error generated due to the nonlinearity of the trans-mission path. A time-dispersive element is provided to produce a correction signal by a temporal extension of the error signal. A combiner is provided to combine the transmission signal and the correction signal. As a result of the temporal extension of the error signal, an error signal segment in the frequency spectrum of a transmission signal transmitted by the nonlinear transmission path is shifted away from the useful frequency range of the transmission signal.

Abstract: An expandable starch-based composition includes a starch, a volatile blowing agent, a non-volatile plasticizer, nucleating agent, and a water-resistant polymer. The expandable starch-based composition can be characterized by having a plasticized starch capable of expanding when rapidly heated to above the boiling point of the volatile blowing agent and the softening point of the plasticized starch. The composition can be used in a method of manufacturing an expandable starch-based bead, wherein the method includes: introducing the composition into an extruder; heating and mixing the composition in order to yield a thermoplastic melt; extruding the thermoplastic melt through a die opening to yield an extruded strand; cooling the extruded strand; and cutting the cooled strand in to beads.
Abstract: A fiber-reinforced and starch-based composition can be prepared by combining two fractions. The first fraction can include a gelatinized starch, water, and fibers, wherein the fibers are substantially homogenously mixed with the starch in an amount sufficient to structurally reinforce the mechanical characteristics of the starch-based composition. The second fraction is then combined with the first fraction, wherein the second fraction can include non-gelatinized starch, non-volatile plasticizer, and a water-resistant polymer. The composition is mixed so as to form a thermoplastic composition being capable of expanding when rapidly heated to above the boiling point of water and the softening point of the plasticized starch. Additionally, fiber-reinforced articles can be prepared from a method of processing the starch-based compositions. Such a method includes introducing the fiber-reinforced starch-based composition into a mold, and molding the composition into a fiber-reinforced article.

Abstract: By way of example, in this example of the invention, it would also be possible to dispense in a manner which is not illustrated with the spring elements 2, and then for the element 1 to carry out an oscillating translational deflection. The invention relates to micromechanical optical elements having a reflective surface which can be deflected electrostatically or electromagnetically in a known manner and which can be used for a large number of applications. The object of the invention is to provide an element such as this at low cost and with improved dynamic deformation behaviour. The elements according to the invention with a reflective surface are in this case held by spring elements, in which case the element which can be deflected is held on mutually opposite sides by in each case at least two mutually independent spring elements.

Abstract: The present invention describes a magnetic resonance imaging method wherein spatially resolved frequency sensitive image data are collected by means of free precession sequences employing very small radio frequency (RF) excitation pulses per unit time which result in highly frequency selective steady-state signals dominated by linear properties of the system, for which the superposition principle holds. By appropriate linear combination of steady state signals of N different frequencies, N resonance lines can be acquired simultaneously. This method allows spectroscopic recordings with very low RF power deposition which renders the method suitable for applications at high static magnetic field strengths.

Abstract: A cable comprises at least two cores stranded together, an expanded inner jacket layer, a substantially circular metallic armor partially contacting the inner jacket to form unfilled interstices outside the inner jacket, and a polymeric outer jacket. The expanded inner jacket substantially takes the shape of the periphery of the stranded cores, providing a non-circular cross section for the expanded inner jacket. A method of producing a cable comprises providing at least two cores, expanding a polymeric material, extruding the expanded polymeric material around the cores, and allowing the expanded polymeric material to collapse onto the cores. A substantially circular metallic armor is applied, resulting in a plurality of unfilled voids between the inner jacket and the metallic armor. An outer jacket is extruded on the metallic armor.

Abstract: The invention provides longitudinally extending track support and track members for a mobile storage unit. The track support's upper surface has at least one protrusion which projects above and extends longitudinally along that upper surface. A mating recess extends within and along the track member's under surface. The recess and protrusion are sized and shaped for loose-fit longitudinal engagement of the protrusion within the recess when the track member is laid atop the track support. This permits limited transverse movement of the track member with respect to the track support, reducing susceptibility of the mobile storage unit's wheels to derailment if a transverse force is applied to mobile storage unit as it rolls along the track.
