  • Patent number: 5223921
    Abstract: Sixty four regions are established on an image-sensed picture from a video camera, wherein evaluating values r.sub.ij, b.sub.ij and y.sub.ij are obtained by averaging color difference signals R-Y, B-Y and a luminance signal Y obtained from a video signal, respectively, over one field period for each region. When producing a gain control signal for each color difference signal, fuzzy inference is made on the basis of these evaluating values and a weighting amount for each color evaluating value for each region is determined. As a result of the weighting, the contribution degree of each color difference signal in a region, not including a light source color temperature axis on a color plane, is reduced to achieve good white balance adjustment.

  • Patent number: 5216851
    Abstract: A covering and protector for a rain gutter prevents the gutter from becoming clogged with leaves or other debris. The covering protector is designed so that leaves (for example) and other debris which may clog the gutter can neither enter the gutter nor clog the protector, the openings in the protector which permit rain to pass into the gutter being vertically disposed. A unitary sheet includes an extended flat portion which does not contain any apertures therein which functions as a closed top portion for covering the open top of the existing gutter and which also serves to interfit under and between existing roofing materials (such as roof shingles) to provide for secure fastening to the roof as well as to provide an uninterrupted smooth path for rainwater to travel off the roof. The top portion is connected to an apertured portion containing a number of apertures each with a flap for directing rain into the surface of the gutter.

  • Patent number: 5199304
    Abstract: A technique for in a thermo-dynamic material testing system for optically measuring changes in specimen size that occur during material testing. Specifically, a pair of jaws, one movable and one fixed, engage opposite ends of the test specimen and are controllably moved with respect to each other in order to impart a desired tensile or compressive force to the specimen. A fixed light source emits a planar light beam, typically collimated laser radiation, that is directed at the specimen by two mirrors mounted to the jaws and on one side of the specimen. One of these mirrors is secured to and moves with the moving jaw and directs the light beam toward the specimen along a transverse path; the other mirror is mounted to the fixed jaw. A fixed light receiver receives the light beam after it has passed over the specimen and has been reflected by a similar pair of mirrors mounted to the jaws but on the other side of the specimen.

  • Patent number: 5195378
    Abstract: Apparatus for a dynamic thermal-mechanical material testing system that not only self-resistively heats and deforms a specimen, both under controlled conditions, but also substantially reduces adverse affects in specimen performance, such as magnetically induced motion and non-uniform specimen heating, that would otherwise result from magnetic fields which impinge upon the specimen and are caused by high heating currents flowing in the apparatus. This reduction is achieved by spatially locating high current carrying conductors used in the apparatus such that these conductors collectively generate substantially balanced, i.e. substantially equal, and opposite magnetic fields that effectively cancel each other out in a volumetric region in the apparatus which contains the specimen and particularly its work zone.

  • Patent number: 5174291
    Abstract: A wearable-type glucose sensor for continuously or intermittently determining the glucose content comprises a short hollow fiber (2) to be positioned in the subcutaneous tissue. This hollow fiber is connected via tubes (3,4) with component parts (5 . . . 12) located outside the body, such as a measuring unit (11). When a perfusion fluid containing the enzyme glucose oxidase is passed through the hollow fiber, a subcutaneous dialysis will take place in which some glucose dissolves in the perfusion fluid through the wall of the hollow fiber. This glucose is completely oxidized by the oxygen dissolved in the perfusion fluid in the presence of the glucose oxidase. By means of the measuring unit the resultant amount of H.sub.2 O.sub.2 or, preferably, the employed amount of O.sub.2 is determined, both of which are a measure of the subcutaneous glucose concentration.

  • Patent number: 5175514
    Abstract: A digital modulator includes a signal source for a digital baseband signal and a signal source for carrier phase information. The digital baseband signal is converted into amplitude information of an I phase, a Q phase, an I' phase and a Q' phase by a mapping circuit. The carrier phase information is converted into four phase information with phases shifted by shift registers to be out of phase by .pi./4 from each other. The digital modulator includes four ROM, each ROM outputting a multiplication result of the corresponding amplitude information and carrier signal based on the corresponding one of the four amplitude information as a higher order address and the corresponding one of the four phase information as a lower order address. These outputs are added to each other in a digital manner and then converted into an analog signal which is supplied as a modulated signal.

  • Patent number: 5159436
    Abstract: A blinking set of displayed collinear elements alternating in color allows simple, rapid, and accurate determination of color misregistration or misconvergence in color television video displays and color television cameras. Operators can readily detect misconvergence due to a shift in a trend line of the collinear elements which is made quite noticeable by repeatedly switching between two patterns, thereby introducing an apparent blinking motion of the misaligned elements in displayed areas that are misconverged. The blinking motion can also be detected by automatic means, thereby eliminating the need for an operator.

  • Patent number: 5124740
    Abstract: Apparatus, and various accompanying methods, for use in a photographic camera for selecting a lens aperture setting and/or flash output configuration for a full flash exposure. Specifically, the lens aperture setting and/or flash output configuration are selected based upon a difference existing between a first parameter, i.e. a guide number, that indicates the amount of output power that the flash is capable of producing and a second parameter, i.e. a depth number, that indicates the amount of flash illumination required to photograph a scene with a pre-defined depth-of-illumination about a subject situated therein. The flash output configuration can be a spread flash with a selected one of a number of different spread angles, a bounce flash or, if the flash unit is an energy saving type, a reduction in (throttling back) the flash output power.

  • Patent number: 5124812
    Abstract: A MUSE encoder converts a HDTV signal into a MUSE signal and supplies the converted MUSE signal to a digital recording circuit 52 of a digital VTR. The supplied MUSE signal includes audio data and additional information, each being a ternary signal. A state of a ternary signal at one sampling point is discriminated by a ternary discrimination circuit 102, with the result thereof being indicated as a two-bit digital signal by a two-bit indicating circuit 103. Accordingly, the number of bits required for the audio data at one sampling point can be compressed from eight bits to two bits. In addition, by converting two successive discriminated results by the ternary discrimination circuit 102 into a binary signal by means of a ternary/binary converting circuit 104, the number of bits required at two sampling points can be reduced from 16 bits to three bits. As a result, a recording bit rate for the MUSE signal, to be digitally recorded on the magnetic tape, can be reduced.
