Abstract: Methods, systems, and devices for techniques for parallel memory cell access are described. A memory device may include multiple tiers of memory cells. During a first duration, a first voltage may be applied to a set of word lines coupled with a tier of memory cells to threshold one or more memory cells included in a first subset of memory cells of the tier. During a second duration, a second voltage may be applied to the set of word lines to write a first logic state to the one or more memory cells of the first subset and to threshold one or more memory cells included in a second subset of memory cells of the tier. During a third duration, a third voltage may be applied to the set of word lines to write a second logic state to the one or more memory cells of the second subset.

Abstract: A method and system for feeding a continuous rod of elastomeric material automatically to a user unit along a feed line having at least one powered portion and extending between an extruder, for forming the rod, and the user unit, and wherein, upstream from the powered portion, the rod is fed along a supporting device defining, for the rod and when at rest, a first path of given fixed length; and wherein, once the rod reaches and is engaged by the powered portion, a movable part of the supporting device is withdrawn from the first path to feed the rod along a second path, one portion of which is a bend of variable length.

Abstract: A process of contactless monitoring the tension in an optical fiber and a tension meter which enables contactliess measurement of the tension in a bare and in a coated optical fiber. By measuring the retardation induced by the birefringence of an optical fiber by means of a polarized light beam incident to the fiber at an angle between about 10° and 25° to the detection optical axis, it is possible to accurately measure tensions over a wide range, i.e., from less than about 10 g to about 450 g. The method enables monitoring the tension during the ramp-up of the drawing process and is particularly advantageous for the control of the drawing tension in manufacturing of NZD, multimode or special fibers. Accurate monitoring of the tension both on a bare and on a coated fiber can also be achieved.

Abstract: A process of contactless monitoring the tension in an optical fibre and a tension meter which enables contactless measurement of the tension in a bare and in a coated optical fibre. By measuring the retardation induced by the birefringence of an optical fibre by means of a polarised light beam incident to the fibre at an angle between about 10° and 25° to the detection optical axis, it is possible to accurately measure tensions over a wide range, i.e., from less than about 10 g to about 450 g. The method enables monitoring the tension during the ramp-up of the drawing process and is particularly advantageous for the control of the drawing tension in manufacturing of NZD, multimode or special fibres.
