  • Patent number: 5814801
    Abstract: Prior methods of reading MaxiCode dataforms have been subject to reduced resolution image scaling and processing and speed constraints of Fourier transform computations. Described spatial domain data extraction methods provide bull's eye center location by T-sequence pixel pattern analysis, axis identification by moment analysis of data cell pairs, and integral width square wave analysis of illumination transitions to avoid reading-line cell fragmentation. The center and top of a MaxiCode are identified in high-resolution pixel data, without scaling reduction or Fourier type frequency domain processing. Data is extracted serially from rows of data cells by sampling along lines of pixels aligned by fragmentation analysis so as to traverse complete rows of data cells. Dynamic thresholding accurately defines illumination value transitions between adjacent linear groups of data cells, each group consisting of one or more data cells of the same reflectivity.

  • Patent number: 5814797
    Abstract: A transponder system for monitoring and logging depository transactions in which bags loaded with funds to be deposited in a bank are put, one at a time, into a bank inlet hopper from which the bags drop through a chute into a vault. Incorporated in each bag is a tag in the form of a passive transponder adapted to receive a radio-frequency interrogation signal and to retransmit the signal as a coded signal defining a number identifying the bag. Installed in the vault is a transceiver that transmits the interrogation signal in a confined radiation field within the vault, the field being intercepted only when a tagged bag falls into the vault or is withdrawn from the vault. When the field is intercepted by a tagged bag, its transponder picks up the interrogation signal and transmits to the transceiver the coded signal identifying the bag.

  • Patent number: 5811787
    Abstract: A electro-optical memory includes a substrate on which is printed (or otherwise inscribed) a complex symbol or "label" or "bar code" of a high density two-dimensional symbology. The bar code contains component symbols or "codewords" which are placed in row and column formation, with a variable number of codewords per row, and a variable number of rows. The symbology utilizes implicit bar code encoding scheme for implicit encoding the number of rows and the number of columns of codewords, as well as a predetermined amount of error correction. The symbology is capable of supporting a fixed number of bar code variants, with each variant having a predetermined number of rows and columns of codewords, and a predetermined error correction capability. For some codewords the implicit encoding scheme is combined with a gray coding scheme to reduce the inter-row codeword crosstalk.

  • Patent number: 5789726
    Abstract: A method of encoding and decoding a transaction card with a block of image data digitally representing the features of a digital portrait of an authorized transaction card user is disclosed along with apparatus for performing the method. The encoding method partitions the digital portrait of the transaction card user into feature blocks. Each feature block is compared against a library of like feature blocks to determine the best match with a pair of library feature blocks. The library's feature blocks are derived from a plurality of portraits taken from the general population. Each library feature block is represented (addressed for access) by a code-vector in a codebook.

  • Patent number: 5767497
    Abstract: A method and apparatus for decoding bar code symbols using an analysis of the ratios of the module size for the bars and spaces of the bar code. The invention is applicable to any bar code having one or more nominal widths in the bars and spaces, and is particularly useful in bar codes having multiples widths in the specification for the bar code and in situations where the bar code signal has a low signal-to-noise ratio, or is degraded because of a damaged, smudged, or dirty bar code, or where the bar code is read at less than the optimum angle. The invention identifies mis-decoded characters and uses adaptive techniques to decode characters previously non-decodable or mis-decoded by standard methods, thereby improving the decode rate as compared to prior techniques. The decoding rate is improved without having to re-scan the bar code for a new signal, thereby making the invention particularly useful for high-speed or one-pass decoding operations.

  • Patent number: 4990773
    Abstract: The invention is a method of evaluating a sample of an underground formation such as drill cuttings to determine the producibility of any hydrocarbons present in the formation by solvating a sample in a polar solvent which will solvate asphaltenes, solvating the sample in an aliphatic solvent which will solvate most crude fractions without solvating asphaltenes, quantitatively measuring the emission fluorescence at a wavelength below 400 nm of both solvated samples at an excitation wavelength at which most petroleum compounds fluoresce, and determining the producibility of any hydrocarbon present in the sample by comparing the emission fluorescence of the two samples to previous correlations made between fluorescence and known producibility.

  • Patent number: 4988873
    Abstract: Apparatus for scan-stimulating a transparent image-storage phosphor to recover a latent image previously formed therein by, for example, an imagewise exposure to x-radiation. Such apparatus includes a source of stimulating radiation and optical apparatus for causing the stimulating radiation to appear (to the storage phosphor) to diverge from the same position in space as the source (x-ray) used to form the latent image in the phosphor. By scanning the phosphor with stimulating radiation propagating along the same path as that traversed by the imagewise-exposing radiation, the recovered image is significantly sharper than prior art techniques.

  • Patent number: 4983844
    Abstract: A fast atomic line filter capable of operating at speeds and quantum efficiencies greatly in excess of prior art atomic line filters. Signal light excites to an intermediate energy level the atoms of a contained vapor. A pump beam further excited these atoms to a higher Rydberg level. Simultaneously the atoms are subjected to an electric field that Stark splits the Rydberg level and ionizes very quickly the doubly excited atoms. The resulting ions or electrons are then detected with near unity quantum efficiency by a detector sensitive to either ions or electrons. By directly detecting the resulting ions or electrons the fast atomic line filter has an inherently higher quantum efficiency and much greater speed than prior art ALF's which must use photosensitive detectors to detect fluorescence.

  • Patent number: 4983834
    Abstract: An improved method and apparatus for detecting and storing for later readout the impingement of certain nuclear particles utilizing a particle detector system having a large area particle detector including a thin or thick film of electron trapping material is disclosed, in which, upon impingement or detection of a nuclear particle, electrons contained in the electron trapping material jump to a higher energy level and a luminescence of a predetermined wavelength is given off by the large area particle detector. The detector may later be subjected to infrared or near-infrared pulsed radiation which will cause the release of photon luminescence of a predetermined wavelength at a position and intensity corresponding to the impinged particles, which can be detected by a suitable sensor and analyzed by a microcomputer.

  • Patent number: 4973843
    Abstract: A pyroelectric sensor senses the infrared rays radiated from the human body and outputs the detected infrared rays as an electric signal. It detects the trespass of somebody on a room and is used for the prevention of crimes and the like. The pyroelectric sensor includes a substrate, an element-pair disposed on the surface of the substrate and an amplification circuit for amplifying the current signals output from the element-pair. The substrate is composed of a material having a thermal conductivity as low as not more than 0.04 cal/cm C. so as to prevent the heat from being released through the substrate. A hole is formed in the substrate. The amplification circuit amplifies the current signals of the element-pair, thereby dispensing with the impedance transformation which is inevitable in the prior art. Thus, the sensitivity of detection is improved and the manufacture of the sensor is facilitated.
