摘要:
A resource is protected by an armor structure comprising a magnetic field such that the magnetic field will interfere with a warhead blast to weaken the blast. In particular, magnetic field will interfere with a molten metal jet from a shaped charge to disperse the jet, allowing subsequent layers of armor to absorb the jet energy without penetration. In one embodiment, the magnetic field is produced by a layer of magnetic material magnetized with the field lines perpendicular to the primary threat direction and typically parallel to the surface of the area to be protected. The magnetic material layer may include ferromagnetic (iron or steel, or other) layers to strengthen and contain the magnetic field, protect the magnetic material and act as additional armor layers. The magnetic layer is typically used in conjunction with an inner shield armor layer to absorb the diffused jet after passing through the magnetic layer.

An improved system and method for data card emulation is provided that enables a single data card to emulate any one of multiple data cards. The data card includes an improved system and method for conveying data involving pulsed light that can read a barcode and can emulate a barcode. The improved system and method for conveying data may also include at least one of a magnetic stripe reader or a magnetic stripe emulator. The data card uses the improved system and method for conveying data to interface with conventional barcode and/or magnetic stripe readers, to interface with other such data cards or other devices having similar circuitry, and to interface with a data management system used to manage barcode and/or magnetic stripe information stored in a memory on the data card.
摘要:
A magnetic attachment system for attaching a first object to a second object. A first magnet structure is attached to the first object and a second magnet structure is attached to the second object by the magnetic attraction between the first magnet structure and second magnet structure. The magnet structures comprise magnetic elements arranged in accordance with patterns based on various codes. In various embodiments, the code has certain autocorrelation properties, the code may be from a set of codes with low cross correlation; an attachment and a release configuration may be achieved by a simple movement of the magnet structures; the magnetic pattern may be configured to allow installation of a selected panel of a set of panels in a given location or orientation while rejecting the remaining panels of the set; or the magnetic pattern is configured using codes with low cross correlation.

An improved field emission system and method is provided that involves field emission structures having electric or magnetic field sources. The magnitudes, polarities, and positions of the magnetic or electric field sources are configured to have desirable correlation properties, which may be in accordance with a code. The correlation properties correspond to a desired spatial force function where spatial forces between field emission structures correspond to relative alignment, separation distance, and the spatial force function.
