摘要: An electrosensitive security laminate including a magnetic layer providing a magnetically encodable substrate. The laminate includes a base layer such as paper, a magnetic layer deposited on the base layer, and a vapor deposited metallic layer either over the magnetic layer or the opposite face of the base layer. Additional security may be achieved by including a decorative intermediate layer having a visibly nonuniform pattern. The user may detect a magnetically encoded pattern using a device which forms a visible pattern in accordance with any magnetic field adjacent the laminate. The patterned intermediate layer where included may be selectively exposed by electrically imprinting the metallized layer, thereby exposing a background pattern within any inscribed indicia.

摘要: An apparatus for generating infrared radiation is provided including an electrical heating element that is able to withstand very high, continuous-use temperatures, surrounding or surrounded by a non-conductive material containing dopants of refractory metal oxides, rare earth oxides, or combinations of both. The material may be shaped about the heating element so that the infrared radiation emissions may be focused and/or directed in a desired manner.
