  • Patent number: 7752830
    Abstract: A fibrous tension member includes a plurality of structural threads and two or more indicator threads. The two or more indicator threads are located with respect to the plurality of structural threads such that a differential elongation between the two or more indicator threads indicates a curvature. The differential elongation between the two or more indicator threads is measured using a change in one or more electrical properties of each of the two or more indicator threads as each of the two or more indicator threads changes in length. A fibrous tension member includes a plurality of structural threads and one or more indicator threads. Each of the one or more indicator threads is more sensitive to elongation in a region of length of the fibrous tension member.

  • Patent number: 7747355
    Abstract: A method of coupling a mechanical power source through an electrical power generator to an electrical load is disclosed. A characteristic of an electrical output is measured from the electrical power generator produced during a power generation cycle during which there is a coupling of the mechanical power source through the electrical power generator to the electrical load. The coupling of the mechanical power source is adjusted through the electrical power generator to the electrical load during a subsequent power generation cycle based at least in part on the measured characteristic of the electrical output.

  • Patent number: 6957608
    Abstract: A method of and device for controlled printing using liquid embossing techniques is disclosed. In accordance with the embodiments of the invention a stamp comprises a differentiated embossing surface with protruding and recessed surfaces to enhance the ability of the stamp to selectively displace liquid ink from a print surface and/or remove solvent from the liquid in a soft curing process. A stamp with differentiated surfaces is fabricated by selectively coating, or otherwise treating the protruding features, the recessed features, or a combination thereof, such that the surface energies and/or wettability of the protruding surfaces and the recessed surfaces are differentiated.

  • Patent number: 6936181
    Abstract: The current invention is directed to a method of patterning a surface or layer in the fabrication of a micro-device. In accordance with a preferred embodiment of the invention, a first mask structure is formed by depositing a layer of a first material onto the surface or layer and embossing the layer with a micro-stamp structure. The layer is preferably embossed as a liquid, which is solidified or cured to form the first mask structure. The first mask structure can be used as an etch-stop mask which is removed in a subsequent processing step or, alternatively, the first mask structure can remain a functional layer of the micro-device. In further embodiments, unmasked regions of the surface or layer are chemically treated through the first mask structure and/or a second material is deposited onto the unmasked regions of the surface or layer through the first mask structure to form a second mask structure and/or a second functional layer of the micro-device.

  • Publication number: 20040197712
    Abstract: In a system for contact printing, two surfaces are brought into intimate aligned contact, under controlled pressure, without the entrapment of air. A controlled bow in a stamp pushes air ahead of a moving contact line between the stamp and a substrate. In one embodiment, the bow is created by a difference in pressure between the two sides of a flexible stamp. In an alternate embodiment, a flexible stamp is rolled into contact with the substrate. Alignment of the stamp and any previously patterned features on the substrate is accomplished with an X-Y translation stage or other suitable mechanism. If an optically clear stamp is utilized, features in the stamp and the substrate can be compared simultaneously and the relative position adjusted. In another aspect, a pattern in a thin film of liquid is created by liquid embossing on an offset substrate. The offset substrate is then brought into contact with the final substrate and the high regions of the liquid film are transferred to that substrate.

  • Publication number: 20040013982
    Abstract: Elastomeric stamps facilitate direct patterning of electrical, biological, chemical, and mechanical materials. A thin film of material is deposited on a substrate. The deposited material, either originally present as a liquid or subsequently liquefied, is patterned by embossing at low pressure using an elastomeric stamp having a raised pattern. The patterned liquid is then cured to form a functional layer. The deposition, embossing, and curing steps may be repeated numerous times with the same or different liquids, and in two or three dimensions. The various deposited layers may, for example, have varying electrical characteristics, interacting so as to produce an integrated electronic component.
