摘要:
An apparatus and method for fabricating electronic devices on a polymeric substrate provide for positionally constraining a polymer substrate on a platen, and heating the constrained polymer substrate to at least a glass transition temperature of the polymer substrate. A heat processable ink is applied to the constrained polymer substrate to form at least a portion of a layer of an electronic device thereon.

A keypad having a virtual floating image that appears to a user to be in a plane other than the apparent plane of the keypad surface. More particularly, the indicia on the keypad appear to float above or below the surface of the device. The keypad can be, for example, the keypad on a cell phone. For such an application there would be more than one array of indicia present on the keypad. For example, there might be ten arrays of indicia, which provide the numerals from 0 to 9 and two more arrays to provide virtual images of the * and # keys. In some embodiments, the keypad is integrated with an illumination source that light up the indicia. The present disclosure also provides a method of manufacturing a key pad with a virtual floating image.

An apparatus and method provides for rotatably cutting and/or laminating layered structures or sheet material supported by webs. A rotary converting apparatus and method of the present invention converts a web comprising a cathode layered structure and a web comprising an anode layered structure into a series of layered electrochemical cell structures supported by a release liner. Employment of a rotary converting process of the present invention provides, among other benefits, for the creation of a product having a finished size, without need for downstream or subsequent cutting.

A liquid crystal cell article includes a layer of liquid crystal material disposed between a first polymeric substrate and a second polymeric substrate. The first polymeric substrate includes a plurality of first parallel conductive traces extending in a first direction and disposed between the layer of liquid crystal material and the first substrate, and a first release liner disposed on the first polymeric substrate. The second polymeric substrate includes a plurality of second parallel conductive traces extending in a second direction orthogonal to the first direction and disposed between the layer of liquid crystal material and the second substrate. The first polymeric substrate further includes a removable portion that is separable from the first polymeric substrate with the first release liner to expose a portion of the layer of liquid crystal material or second parallel conductive traces.

Folded radio frequency identification tag devices and methods for high-volume, low-cost production are disclosed. The folded construction of the devices and methods of the present invention can reduce the complexity of the RFID tags by providing a one-sided circuit design. The resonant frequency of the circuits formed on the devices may be tuned by severing selected connections to one or more tuning capacitor plates that form a part of the capacitor structure. Severing connections to the tuning capacitor plates changes the capacitance of the circuit which, in turn, changes the resonant frequency of the circuit.

Articles enabled by an injection molding process that molds parts on a carrier web located between mold halves and uses ultrasonic energy to assist flow of polymer melt into the mold cavity. One such article is a carrier web having a high density of molded parts, i.e., bearing an array of molded articles adhered to the web in rows and columns, the articles being spaced closer (center-to-center or edge-to-edge) than the diagonal spacing between articles in the next adjacent row and next adjacent column. Another such article is a microneedle array on a land no more than 250 μm thick on which at least 60% of the microneedles across the array are filled (i.e., completely formed).

A microreplicated achromatic lens is disclosed. The article includes a web including first and second opposed surfaces. The first surface includes a first microreplicated structure having a plurality of first features. The second surface includes a second microreplicated structure having a plurality of second features. Opposing first and second features are registered to within 10 micrometers. Corresponding opposed first and second features cooperate to form an achromatic microlens element.
摘要:
In general, techniques are described for the creation and execution of accurate models for the manufacture of complex, multi-layered materials. The techniques may be used to calculate variations of a process parameter within the material during the manufacturing process. A method comprises receiving segment data that partitions a manufacturing process into a set of segments having at least one layer of a material. For example, the segment data may partition the manufacturing processes along a path traversed by the material within the manufacturing process. The method further comprises receiving curvature data for the layers, and calculating values for a process parameter through the layers of the segments as a function of the curvature data. The method may comprise invoking a one-dimensional model, such as a one-dimensional finite difference model, to calculate the values for the defined segments and layers.
摘要:
A product stacking apparatus and method employs one or more stations, each including a stationary stacking platform or a conveyor upon which spaced-apart pucks are coupled for travel thereon. A product delivery apparatus drives one or more movable webs to which segmented product sheets are removably affixed. The product delivery apparatus includes one or more rotatable lamination interfaces associated with each of the stations for transferring product sheets from the webs to the pucks on a repetitive basis to produce a stack of product sheets on the respective pucks. Each of the segmented product sheets may define all or a portion of an electrochemical cell, all or a portion of a pad including layers of film or sheet material, wherein a portion of each of the layers is provided with a bonding feature, or all or a portion of a pack comprising layers of medical dressing. A puck need not be in motion during the transfer of the product sheet from the lamination roll to the puck. The puck may or may not be attached to a conveyor, but the conveyor need not be in motion during the lamination or stack building process. In this case, a roller is moved across the puck and simultaneously rotated so a point on the surface of the roller interfaces with the puck at the same location on each pass.
