Abstract: The present invention provides methods for providing a personalized list of dietary nutraceuticals to an individual, wherein at least one of the nutraceuticals affects the bioavailability of at least one other of the nutraceuticals, the methods including adjusting the amount of the affected nutraceutical based on the influence of the affecting nutraceutical on the bioavailability thereof. The present invention further provides a computerized system including a database and a processor which includes modules configured for providing the list of nutraceuticals according to the invention.

Abstract: A system and method for reading an RFID data tag comprising a plurality of diffractive elements being indicative of machine-readable data carried by the tag are provided. The diffractive elements have such shape that the dimension of the diffractive elements along one axis is substantially different than the dimension of the elements along the perpendicular axis. Each diffractive element is oriented in a direction other than the direction of its neighboring elements. The system comprises a transmitting antenna configured for emitting an RF radiation signal at a predetermined polarization towards the tag; and a receiving antenna configured for collecting re-radiated RF radiation produced by the tag in response to the RF radiation signal at a polarization orthogonal to the polarization of the transmitting antenna and generating electromagnetic signals indicative of the data carried by the tag.

Abstract: A radio frequency identification data tag, a system and a method for reading the tag are described. The tag comprises a plurality of diffractive elements which are indicative of data carried by the tag. The diffractive elements have such shape that the dimension of the diffractive elements along one axis is substantially different than the dimension of the elements along the perpendicular axis. The diffractive elements are arranged in columns and rows in accordance with a predetermined layout scheme. In each column, the diffractive element is oriented in a direction other than the direction of the elements in the neighboring columns. The system for reading the tag comprises an array of transmitting (Tx) antennas for emitting an RF transmitted radiation signal at a predetermined polarization towards the tag, and an array of receiving (Rx) antennas configured for collecting re-radiated RF radiation produced by the tag at a polarization orthogonal to the polarization of the transmitting antenna.

Abstract: A method of marking an article to enable its identification, by applying to the article a conductive path, which is at least partially coated with a dye layer of at least one compound selected from voltage sensitive fluorescent dye (VSFD), mixture of such dyes, electro luminescent (EL) compound, OLED compound or mixtures thereof, the dye layer being excitable to emit fluorescent radiation, which serves to identify the article.

Abstract: Photographic process, in which a substrate comprising a plurality of superimposed layers of photochromic materials sensitive to different light wavelengths is provided. The object to be photographed is scanned and a digital file defining the image of the object is generated from the scanning. A plurality of sources of laser light having different wavelengths, each of which is the wavelength to which one of the photochromic materials is sensitive is provided and the layers of photochromic materials are irradiated by means of the laser beams produced by the sources, according to a program determined by the digital file, whereby to develop in each pixel of the substrate the color that it has in the image. The colors thus generated in the pixels of the substrate layers; and the background areas of the substrate layers are set.
