Abstract: The present invention provides for a common substrate with multiple sections, each constituting a separate layer of a memory device. Fold lines are arranged on the substrate to define separate sections and to provide a means for folding the sections on each other to form a multiple-layer memory device. In one application, a substrate has a fold line formed by alterations to the substrate material to form a fold line on the substrate. A first conductor section is formed with an array of parallel conductors or wires spaced across the section. A second section on the common substrate has an array of parallel conductors or wires spaced across the second section, the conductors being perpendicular to the conductors on the first section. The first and second sections are folded along the fold line over on top of each other, after a semiconductor layer has been deposited on one or both of the conductor layers, thereby forming a matrix of memory cells.

Abstract: A drop deposition apparatus, and a method and computer program products using the drop deposition apparatus, for fabricating at least one addressable array of biopolymers on a substrate. The drop deposition apparatus has a drop dispenser unit and a sensing element. The method comprises includes for each of multiple addresses, dispensing droplets carrying the biopolymers or biopolymer precursors from a drop dispenser unit onto the sensing element, and onto the substrate so as to fabricate the array. Electrical signals resulting from dispensed droplets striking the sensing element are detected. A performance characteristic of the deposition apparatus is evaluated based on the detected signals.

Abstract: A system and method for extracting carrier liquid utilizes thermal energy generated above a surface from which the carrier liquid is being extracted. The thermal energy can be generated by a heating element positioned over the surface. The thermal energy is used to evaporate the carrier liquid on the surface so that the evaporated carrier liquid can be condensed for collection.

Abstract: Determining inkjet printer pen turn-on voltages is disclosed. An inkjet printer has a number of pens, and a number of sets of nozzles in each pen. Each set of nozzles of a pen is fired at each of a number of voltages, to obtain a voltage-value curve for each set of nozzles. A nozzle turn-on voltage for each set of nozzles is determined based on a maximum slope of its voltage-value curve. The turn-on voltage for each pen is determined based on the nozzle turn-on voltages of the voltage-value curves for its sets of nozzles.

Abstract: Systems and methods are described for increasing the binding strength of a bound text body by increasing the spinal surface area exposed for adhesive penetration greater than an area corresponding to the product of the sheet height dimension, the sheet thickness dimension and the number of sheets. In one aspect, sheet-wise conditioning of the binding area is performed prior to the application of adhesive to increase the bond area between sheets of the text body. In another aspect, the spinal surface area exposed for adhesive penetration is increased as adhesive is applied.
