The invention provides a detector comprising a metamaterial absorber and a micro-bolometer arranged to detect terahertz (THz) radiation. The metamaterial absorber can absorb multiple frequency bands, from the infrared and the THz regions of the electromagnetic spectrum. The detector is scalable to be suitable for use in a focal plane array.

The invention also provides a hybrid of a plasmonic filter, e.g. for optical radiation, and a metamaterial absorber for terahertz (and/or infrared) radiation, to create a single material capable of absorbing narrow band terahertz radiation and filtering radiation in another part of the spectrum, e.g. optical radiation. Such material has great potential in future imaging technology where hybridisation can maximise the spectral information density of an optical system.

Machine-readable light-colored or invisible, but luminescent, postage-evidencing symbology and dark, readable other postage information are printed, preferably in a single print operation, to provide large amounts of information without diminishing read rates. The resulting combination image can be printed independent of substrate material to enable the provision of a high information density without obscuring any one component. The postage-evidencing symbology is printed in large-format and can include redundant information within an IBI image or between an IBI and visible dark image for a variety of practical purposes. In a preferred form, the images are printed using conventional ink jet printers using water-based inks. In one embodiment of this type, the images are printed with a conventional two-cartridge color ink jet printer by printing postage-evidencing symbology with a single-color ink and printing the visible dark image as a composite dark color from a standard multi-color cartridge.

Circuits, architectures, systems, methods, algorithms, software and firmware for indicating positions of defective data storage cells using reserved (e.g., “pilot”) cells. The circuit generally includes a memory having multiple subunits, each subunit containing multiple data storage cells and at least one reserved cell. The reserved cells store information identifying whether one or more data storage cells in a subunit are defective. The method of identifying defective memory positions generally includes determining the status of data storage cells in a multi-subunit memory; storing such status information in a reserved cell; and reading the reserved cell. In various embodiments, the reserved cells differentiate between fewer voltage levels and/or store a lower density of information than the data storage cells. The present invention improves error correction capabilities using cells that are typically already available in many conventional nonvolatile memories. In some cases, marking data from defective cells as erasures effectively doubles the error correction capability of the system. When the reserved cells contain more than one level, the overhead for a given level of fault coverage decreases as a function of memory size.

A system and related techniques generate and encode identification or transactional media such as passports, driver's licenses or others with a symbol set defined in a color space such as 8-bit color or grayscale, 24, 32, 48 or other bit depths or resolutions. Because blocks, lines or other symbol shapes may each take on more than a black or white color value, information density for the resulting bar code, biometric scan or other symbol set may be increased, and likewise take advantage of the resolution of close-contact scanners and other input devices. In embodiments, the symbols may be encoded using a selected subset of the overall color space, for instance by selecting an evenly spaced subset consisting of 4, 8 or 16 color values evenly divided within a 256 tone grayscale space, or using other values or subsets. In other embodiments the selected subset may be selected according to intervals or functions which are not evenly divided, for instance to approximate the gamma curve of a detection device, or according to other functions. The information density of the resulting IDs, credit cards, checks or other objects or media may therefore be increased, while still retaining a high degree of accuracy.
