  • Patent number: 8915583
    Abstract: Methods and/or systems for printing or otherwise evincing temporary indicia on media with disappearing inks are described along with suitable disappearing ink formulations and media constructions for executing the same. In particular embodiments, the methods and/or systems described employ a plurality of disappearing inks with different disappearing rates. In one embodiment, a barrier layer that is selectively used to cover a major surface of the media is employed to substantially block or otherwise regulate a rate of phase transitions (e.g., evaporation and/or sublimation) experienced by ink borne by the media.

  • Publication number: 20130261409
    Abstract: Various methods, devices and systems for patch based physical, physiological, chemical, and biochemical sensors that diagnose and monitor disease states are described. The patch based sensors provide a panel of specific analyte parameters that determine one or more physiological conditions and/or the level of healing progression of a wound. The use of such analyte panels in local or remote monitoring of parameters related to various disease states is also described.

  • Publication number: 20050136538
    Abstract: One embodiment of the invention describes a novel method for providing a substrate for selective cell patterning, wherein the method comprises contacting an epoxide coated substrate surface with a bi-functional molecule having an epoxide end group and reacting these end groups with the substrate surface through a photochemically induced acid coupling reaction. The bi-functional molecule is applied in solution to the substrate surface as a photo-sensitive coating. A photomask stencil is used to deposit electromagnetic radiation into the coating in predetermined locations to form a desired pattern of the coating. The patterned substrate is provided by washing coating from the substrate leaving the bi-functional molecule attached to the substrate in those areas exposed to the radiation providing thereby cell adhesive moieties in controlled locations on the substrate.
