摘要: A method and apparatus for verifying the authenticity of a document relative to a previously programmed document are disclosed. The method provides a broadband light source; illuminates a document with the light source; collects reflected light; converts it into a corresponding electrical signal or signals; digitizes the electrical signals; and prepares a spectral signature of the document for further analysis. The spectral signature can also be normalized to account for variations in analyzed documents caused by soiling and fading. The method also provides for comparing a previously programmed and stored spectral signature to the spectral signature of a test document using a matching value to indicate whether the test document is authentic or not. The apparatus provides a device for application of the method for verifying document authenticity.

摘要: An electromagnetic antenna includes a multiply connected surface, such as a toroidal surface; first and second insulated conductors; and first and second signal terminals. The first insulated conductor extends around and over the surface with a first pitch or winding sense from a first node to a second node. The second insulated conductor also extends around and over the surface with a second pitch or winding sense, which is opposite from the first pitch or winding sense, from a third node to a fourth node. The first and second insulated conductors are contrawound relative to each other around and over the surface. In one embodiment of the invention, at least one of the nodes is open. In other embodiments of the invention, the signal terminals are structured for connection to a cooperative antenna structure.

摘要: An object tracking system includes a sensor grid having a plurality of sensor clusters configured to sense the presence of a magnetic field of an object. Each sensor cluster includes three or more single-axis magnetic sensors. The sensors in a cluster may be arranged with their axes parallel to one another. The sensor grid may account for ambient magnetic noise by measuring the magnetic field in a zone a distance away from the object to update the ambient magnetic field noise measurement. The sensor grid or a portion thereof may include a plurality of sensors printed on a common sheet. The sensor grid may comprise one or more sheets overlapped or interconnected. The system may track an object and determine up to three degrees of positioning and three degrees of orientation by using a geometric solution of the intercepts of magnetic field strengths obtained from information collected by the magnetic sensors.

摘要: A quarter wave coaxial cavity resonator for producing corona discharge plasma from is presented. The quarter wave coaxial cavity resonator has a folded cavity made of opposing concentric cavity members that are nested together to form a continuous cavity ending in a aperture. A center conductor with a tip is positioned in the cavity. The folded cavity advantageously permits the coaxial cavity resonator to resonate at a lower operating frequency than an unfolded quarter wave coaxial cavity resonator of the same length. Embodiments of the quarter wave coaxial cavity resonator use narrower apertures to reduce radiative losses, and include center conductors that are reactive load elements, such as helical coils. When a radio frequency (RF) oscillation is produced in the quarter wave coaxial cavity resonator, corona discharge plasma is formed at the tip of the center conductor. The corona discharge plasma can be used to ignite combustible materials in combustion chambers of combustion engines.

摘要: An apparatus and method for igniting combustible materials in a combustion chamber of a combustion engine using corona discharge plasma from a quarter wave coaxial cavity resonator. A tapered quarter wave coaxial cavity resonator is adapted to mate with the combustion chamber. The quarter wave coaxial cavity resonator is coupled with an energy shaping means, or waveform generator, that develops the appropriate waveform for triggering radio frequency oscillations in the quarter wave coaxial cavity resonator. A loop coupling is angularly positioned within the quarter wave coaxial cavity resonator to match impedances between the quarter wave coaxial cavity resonator and the energy shaping means, or waveform generator. Radio frequency oscillations produce a standing wave in the quarter wave coaxial cavity resonator and a corona discharge plasma develops near the center conductor. The corona discharge plasma developed near the center conductor ignites the combustible materials in the combustion chamber of the combustion engine.
