Abstract: A member for detecting and/or measuring the level of concentration of a chemical substance in a medium comprises a non-metal substrate bearing a dielectric layer. A detection reactant which is capable of reacting with the substance to be detected is put on the dielectric layer and the assembly is put into the medium to be investigated, whereupon an optically detectable layer of the substance to be detected is formed on the detection reactant. The substrate is light-absorbing and one or more further dielectric layers is or are disposed between the substrate and the first-mentioned dielectric layer thereon, the thickness of the further dielectric layer or layers being such that the overall assembly comprising all the dielectric layers, the layer of detection reactant thereon and the layer of substance to be detected, is reflection-reducing in respect of non-monochromatic light which is reflected at the surface of the substrate on which the array of layers is disposed, in the wavelength range of from 525 to 600 nm.

Abstract: Ice nucleation bacteria are modified in vitro to confer an ice nucleation deficient phenotype. Modification is accomplished by deletion, substitution, insertion, inversion, or transversion of a DNA segment within the gene locus responsible for the INA phenotype. By limiting such mutations to the particular gene locus, the modified microorganisms are genetically stable and free from random mutations which might adversely affect their competitive fitness. The modified microorganisms are useful for prevention of frost damage to susceptible plant hosts.

Title: Fast spatial segmenter for handwritten characters
Inventor: JEANTY HENRY H
IPC: G06V30/10
Filed: 1989-10-02
Granted: 1995-06-13
Abstract: A character recognition system 10 includes a segmentation processor  12  which  is  coupled  between  an  electronic tablet 14 and a character recognizer 18.  The tablet 14 has an associated stylus or pen 15 with which a user forms  symbols,   such  as  block  printing  or  script characters, on a surface of the tablet 14. The tablet 14 has x-axis and y-axis output signals expressive of the position of the pen 15 within an x-y tablet coordinate system. A stroke capture device 16 intercepts the x-y outputs from the tablet to generate x-y position pair data for the segmentation processor 12. An output of the segmentation processor 12 is data expressive of connected strokes and unconnected strokes which is input to the character  recognizer  18.  The  segmentation  method  and apparatus segments real-time handwriting outputs from the electronic tablet by a recursive method which rapidly locates  a  general  area  in  which  two strokes  might intersect  by  successively  finding  intersections  of maximal areas or boxes associated with the strokes until an exit condition is determined.

Abstract: ABSTRACT OF THE DISCLOSURE.         To hold and transport folded printed products, a belt (18),for example a steel ribbon, has separating and holding elements (19), for example flat metal plates or sheets secured thereto. The transport belt (8) with the separating elements thereon is guided about a curved guide surface (20), for example a roller, whereupon the separating elements will spread or fan out from the underlying transport belt,  In this spread or fanned out position, they can accept one sheet element (11) of a spread apart folded product (1), the separating element (19) gripping that sheet element (11) between itself and the transport belt.  The folded products can then be transported, in scale-like or imbricated or shingled form, to a storage position, for example by rolling up the steel ribbon (8).  The folded products are released by again passing the belt about a curved directing surface (26) which may again be a roller or the same roller, which will agin fan out the separating elements, spreading them from the transport belt (18) for release of the folded products, for example for placement on a saddle or other support structure where they are held suspended from beneath the bend or fold thereof.

Title: Touch panel and method for controlling same
Inventor: PERSON HERMAN R
IPC: G06F3/042
Filed: 1990-04-06
Granted: 1996-04-16
Abstract: The touch panel of the present invention comprises a plurality of beam emitter-detector pairs disposed around the perimeter of a video display area.  The emitters direct energy beams toward the detectors which are located directly opposite across the display area from the emitters.  A programmed central processor is connected to the emitters and is programmed to sequentially scan the emitters for actuating the emitters one at a time to create a modulated energy beam which is intermittently turned on and off for predetermined periods of time at a predetermined frequency.  The detectors sense the modulated energy beams and create an electrical signal which is fed through a comparator and then to the central processor so that the central processor can analyze and determine the location of any blockage which appears on the screen.
