摘要:
A method of embossing a sheet material includes: heating at least a portion of the sheet directly or indirectly with radiant energy from a radiant energy source; pressing a tool against the heated portion of the sheet, thereby patterning a surface of the sheet; and separating the sheet and the tool. The radiant energy may travel through a solid material that is relatively transparent to radiation, on its way to being absorbed by a relatively-absorptive material. The relatively-transparent material may be an unheated portion of the sheet, and the relatively-absorptive material may be either the tool or the heated portion of the sheet. Alternatively, the relatively-transparent material may be the tool, and the relatively-absorptive material may be all or part of the sheet. The method may be performed as one or more roll-to-roll operations.

摘要:
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.

摘要:
A radio frequency identification (RIFD) inlay includes an electrical connection between a chip and an antenna. The electrical connection includes conductive interposer leads and a capacitive connection. The capacitive connection may involve putting the antenna and the interposer leads into close proximity, with dielectric pads therebetween, to allow capacitive coupling between the antenna and the interposer leads. The dielectric pads may include a non-conductive adhesive and a high dielectric material, such as a titanium oxide. The connections provide a convenient, fast, and effective way to operatively couple antennas and interposers. The RFID inlay may be part of an RFID label or RFID tag.

The present invention is directed to an electrically switchable laminate construction for applications including smart windows, and other uses and applications in which light management is desired. The electro-optical laminate construction has scattering and transparent modes of operation for dynamically controlling electromagnetic radiation flow.
摘要:
A method for detecting interactions between first and second interacting molecules at variable sensitivity. This variable sensitivity may be obtained by providing for the overexpression of either a bait hybrid protein containing a DNA binding domain (desensitization) or a prey hybrid protein containing the DNA activation domain for a reporter gene (enhanced sensitivity). The use of exogenous activators of one or the other according to the needs of a particular system is readily accomplished.
摘要:
A method for labeling fabrics, such as fabric garments, and a heat-transfer label well-suited for use in the method. In one embodiment, the heat-transfer label includes (a) a support portion; and (b) a transfer portion, the transfer portion being positioned over the support portion for transfer of the transfer portion from the support portion to an article of fabric under conditions of heat and pressure, the transfer portion including (i) an ink design layer; (ii) a heat-activatable adhesive layer; and (iii) an RFID device.
摘要:
A method of forming an electrically-conductive pattern includes selectively electroplating the top portions of a substrate that corresponds to the pattern, and separating the conductive pattern from the substrate. The electroplating may also include electrically connecting the conductive pattern to an electrical component. Conductive ink, such as ink including carbon particles, may be selectively placed on the conductive substrate to facilitate plating of the desired pattern and/or to facilitate separation of the pattern from the substrate. An example of a conductive pattern is an antenna for a radio-frequency identification (RFID) device such as a label or a tag. One example of an electrical component that may be electrically connected to the antenna, is an RFID strap or chip.
摘要:
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.
