20150367380 | BREATH-ACTIVATED IMAGES AND ANTI-COUNTERFEIT AUTHENTICATION FEATURES FORMED OF NANOPILLAR ARRAYS - Disclosed are articles having authentication features, as well as methods for authenticating such articles by forming authentication features to prevent or diminish counterfeiting activities. A surface of an article to be authenticated (or a surface of a component associated with the article) may have a region with a periodic array of nanopillars comprising a polymeric material formed thereon. The array of nanopillars thus defines an authentication feature (e.g., a graphic image or other pattern). In certain aspects, the authentication feature may be substantially invisible to the human eye under normal conditions, but revealed when condensate is created on the surface by exposure to moisture or vapor (e.g., human breath). The methods of forming nanopillar arrays disclosed herein are simple and permit single-step replication with high fidelity. Furthermore, the methods may be used with a variety of substrates, including fabric, textiles, leather, glass, paper, and metals by way of non-limiting example. | 12-24-2015 |

20150268689 | ULTRA LOW POWER TEMPERATURE INSENSITIVE CURRENT SOURCE WITH LINE AND LOAD REGULATION - A temperature insensitive sub-nA current reference is presented with pA-range power overhead. The main concept is to linearly reduce the gate voltage of a sub-threshold-biased MOSFET as temperature increases, in order to compensate for exponential dependence of drain current on temperature. For example, a MOSFET-only, 20 pA, 780 ppm/° C. current reference that consumes 23 pW is disclosed, marking the lowest reported power among current references. The circuit exploits sub-threshold-biased MOSFETs and a complementary-to-absolute temperature (CTAT) gate voltage to compensate for temperature dependency. The design shows high immunity to supply voltage of 0.58%/V and a load sensitivity of 0.25%/V. | 09-24-2015 |
