  • Publication number: 20110284639
    Abstract: A method deconvolves a multiplexed fluorescence spectral signal into its component single-color fluorescence spectra emitted by contributing fluorophore types. A spectral database contains a parameter set for each of the component spectra. Optical codes are received as the multiplexed signals. A sliding window technique estimates a number and location of local peaks for the component spectra. Allowable variation ranges are assigned for the corresponding parameter sets. Each multiplexed signal is deconvolved into a sum of parametric values to generate a list of its component spectra. Encoded and received optical codes, in the form of multiplexed signals, are decoded and identified by their component spectra and contributing fluorophore types. A system for deconvolving the multiplexed signals includes a spectral database containing the parameter sets, a detection element receiving the optical codes, and a signal processor encoded to analyze and deconvolve the multiplexed signals.

  • Patent number: 7793846
    Abstract: In one embodiment, the invention provides a method for forming a full color laser engraved image on an ID card. As described below, a special image capable layer is prepared that is addressable by one or more near infrared (NIR) lasers. Each type of particle contained within the image capable layer is associated with a particular color (e.g., cyan, magenta, or yellow) and is responsive (i.e., can selectively absorb) a particular wavelength of laser energy to form a laser engraved pixel in that respective color. In one embodiment, the particles are selected such that the wavelengths that they respond to do not overlap significantly. By providing discrete physical particles and preventing a given particle from responding to more than one laser wavelength, it can be possible to minimize so-called “cross talk” between the cyan, magenta, and yellow centers and minimize contamination and/or chemical mixing of image formers. This helps to ensure image accuracy and quality.

The acquisition unit acquires a code image corresponding to an operation position on the medium in conjunction with a user's operation with respect to the medium. The specifying unit specifies the medium identification information included in the code image acquired by the acquisition unit. The database stores personal information associated with the medium identification information specified by the specifying unit.

  • Patent number: 7607586
    Abstract: A RF structure including a semiconductor chip with an RF element having an RF core with two electrically connected chip pads, including a chip carrier having two carrier pads connected to the two chip pads and including an antenna connected to the carrier pads and electrically connected to the chip pads and to the RF core. The antenna is formed of wires, printed conductors, seal rings or other structures on, below or above the top plane of the semiconductor chip. A primary element is provided where the RF element is a secondary element. The primary element occupies a primary region and the RF core of the secondary element occupies a secondary region where the secondary region is much smaller than the primary region. The RF core secondary region is formed with the same native processing as used for the primary element.

  • Publication number: 20090159510
    Abstract: Rare Earth downconverting compositions for optical encoding objects and related methods and apparatuses. The rare earth (RE) downconverting phosphor compositions are capable of generating a unique optical spectrum or unique optical signature from which an optical code or barcode can be derived. In one exemplary embodiment, the RE downconverting phosphor composition may contain two or more lanthanide materials each having a host and at least one downconverting emitter. Each lanthanide material emits a detectable electromagnetic radiation emission peak at an intensity, which is proportional to the amount of emitter present, upon excitation with an absorbable electromagnetic radiation, the emitted radiation comprising a lower energy, i.e., a longer wavelength than the absorbable radiation. One or more ratios of the intensities of the emitted detectable electromagnetic radiation may be used to uniquely identify the composition.

The coded data identifies a plurality of position coordinates on the interface surface and an identity of the product item. The receptacle comprises: a receptacle body and an opening through which the product item is placed within the receptacle body. A sensing device is positioned for scanning product items as they are placed through the opening. The sensing device emits a scanning beam across the opening of the receptacle body and generates, using sensed coded data, indicating data indicative of a position coordinate on the interface surface and the identity of the product item.
