摘要:
A method of conveying information to an interrogator includes the interrogator sensing the presence of a resonant radio frequency circuit that is tuned to a first resonant frequency. Responsive to a parasitic radio frequency circuit being brought to within a parasitic coupling distance of the resonant radio frequency circuit, the interrogator senses a shift in the resonant frequency of the resonant radio frequency circuit, wherein the shift in the resonant frequency conveys information to the interrogator

A memory structure includes a memory storage element electrically coupled to a control element. The control element comprises a tunnel-junction device. The memory storage element may also comprise a tunnel-junction device. Methods for fusing a tunnel-junction device of a memory storage element without fusing a tunnel-junction device of an associated control element are disclosed. The memory storage element may have an effective cross-sectional area that is greater than an effective cross-sectional area of the control element. A reference element comprising a tunnel-junction device may be used with a current source to fuse a memory storage element without fusing a tunnel-junction device of an associated control element. Methods of making the memory structure and using it in electronic devices are disclosed.

The present invention relates to a microcapsule that can be used to form a rewritable medium for visual displays that are stable in the presence of electric fields having a strength that is typical in the work environment. The microcapsule of the invention comprises charged particles of one or more colors that are suspended in a phase change material that has a melting temperature in the range of between about 30° C and about 200° C. The microcapsules can be used to form an electrophoretic coating that includes microcapsules of the invention distributed throughout a polymer matrix. The electrophoretic coating can be used to coat a substrate to form a rewritable medium.
