Abstract: This invention relates to a device for emitting addressable locations comprises parallel spaced-apart first conductors (10) intersecting with parallel spaced-apart second conductors (11). The intersecting first and second conductors define addressable locations where electrons (12) are emitted in response to the application of an energizing voltage. One face of the first conductors is covered with an insulating layer (13) against which the second conductors (11) are applied, this insulating layer (13) forming a tunnel barrier for hot electrons (12) that travel ballistically through and are emitted from the second conductors (11) in response to the application of the energizing voltage. The emitted electrons impinge a target (30, 40, 50) which can be a light-emitting screen of a flat panel display, such as an electroluminescent polymer of a flat panel screen, or an electroluminescent phosphorous screen, or a target wafer bombarded by the electrons emitted from a flexible e-beam lithography mask.

Abstract: The present invention is related to a method for performing digital holographic imaging (DHI), said DHI being characterized by the fact that images of a sample are obtained by applying numerical means to reconstruct holograms of the sample. In the method of the invention, the sample is in a medium with controlled properties that influence the behaviour of the sample, and/or that influence the process of hologram formation. The information content of one hologram, or of a plurality of holograms, recorded with the sample in one medium, or in a plurality of medium, is used to reconstruct one image of the sample, or a plurality of images of the sample, that describe quantitatively one property of the sample, or a plurality of properties of the sample.

Abstract: A tandem cell or photoelectrochemical system for the cleavage of water to hydrogen and oxygen by visible light has two superimposed photocells, both cells being connected electrically. The photoactive material in the top cell is a semiconducting oxide placed in contact with an aqueous solution. This semiconducting oxide absorbs the blue and green part of the solar emission spectrum of a light source or light sources and generates with the energy collected oxygen and protons from water. The not absorbed yellow and red light transmits the top cell and enters a second photocell, the bottom cell, which is mounted, in the direction of the light behind, preferably directly behind the top cell. The bottom cell includes a dye-sensitized mesoporous photovoltaic film. The bottom cell converts the yellow, red and near infrared portion of the sunlight to drive the reduction of the protons, which are produced in the top cell during the photo catalytic water oxidation process, to hydrogen.

Abstract: We present a method and apparatus for local and superficial measurement of the optical properties of turbid media. The depth probed is on the order of 1 transport mean free path of the photon. The absorption coefficient, reduced scattering coefficient and the phase function parameter ?=(1?g2)/(1?g1) are optical parameters computed from a single measurement of the spatially resolved reflectance close to the source. Images of superficial structures of the medium can be obtained by performing multi-site measurements. An important application of this technique is the characterization of biological tissues, for example for medical diagnostic purposes. Measurements on biological tissues can be achieved using a probe of diameter less than 2 mm, and the average volume probed is on the order of 1 mm3. Separate images of absorption and tissue structure can be achieved with a resolution of approximately one transport mean free path of the considered tissue.

Abstract: A displacement of a pedestrian is determined from his or her accelerations by detecting accelerations which is substantially non vertical, determining a characteristic feature in the detected accelerations correlated with a step frequency, determining the displacement on the basis of said determined characteristic. The acceleration data can be submitted to waveform analysis to determine an actualized time interval of an occurring feature, such a maximum values, from which it is determined whether the actualized time period falls within determined limit values. The currently detected characteristic feature is then determined as corresponding to a displacement step if the actualized time period falls within said determined limit value. By using non-vertical acceleration measurements, the invention can make it possible to distinguish between forward, backward, left and right stepping movements and take these into account for the navigation.

Abstract: This invention discloses new methods, security devices and apparatuses for authenticating documents and valuable articles which may be applied to any support, including transparent synthetic materials and traditional opaque materials such as paper. The invention relates to moire intensity profiles which occur in the superposition of periodic or aperiodic geometrically transformed structures. By using a specially designed basic screen and master screen, where at least the basic screen is comprised in the document, a moire intensity profile of a chosen shape becomes visible in their superposition, thereby allowing the authentication of the document. If a microlens structure is used as a master screen, the document comprising the basic screen may be printed on an opaque reflective support, thereby enabling the visualization of the moire intensity profile by reflection.
