  • Patent number: 5339330
    Abstract: A cellular communications system is provided having both surface and satellite nodes which are fully integrated for providing service over large areas. A spread spectrum system is used with code division multiple access (CDMA) employing forward error correction coding (FECC) to enhance the effective gain and selectivity of the system. Multiple beam, relatively high gain antennas are disposed in the satellite nodes to establish a first set of cells, and by coupling the extra gain obtained with FECC to the high gain satellite-node antennas, enough gain is created in the satellite part of the system such that a user need only use a small, mobile handset with a non-directional antenna for communications with both ground nodes and satellite nodes. User position information is also available. A digital data interleaving feature reduces fading. Each transmitter includes a coder representative of its output power level.

  • Patent number: 5336879
    Abstract: In a pixel array having an array of pixel elements, a plurality of row select lines, a plurality of column select lines, and a plurality of signal lines, a pixel element is disclosed for minimizing dead space in an overall imager matrix which includes many pixel arrays. The pixel element includes a phototransducer device for detecting light, transmitting light or emitting light and a pair of series switching transistors coupled between the phototransducer device and a predetermined signal line. In addition, the pixel element includes at least one configurable transistor which is independent of the pair of switching transistors. This configurable transistor is interconnected with other configurable transistors from other pixel elements throughout the array in order to implement desirable functions, for example scanning circuitry, and amplification circuitry such that the dead space of each pixel array and, consequently, the overall imager array is minimized.

  • Patent number: 5335370
    Abstract: A cuff seal utilized in a portion of a full pressure suit which envelopes a limb of a wearers body, the full pressure suit defining at least one full pressure compartment. The cuff seal includes a gas impermeable outer sheath configured to envelope a portion of the limb, the sheath having a first end in pressurized communication with the full pressure compartment, and a second end having an opening through which a portion of said limb exteriorly protrudes from the interior of the full pressure compartment. A gas impermeable inner sleeve is provided having an outer end, an intermediate section and an inner end disposed within the sheath, the outer end of the sleeve being joined in a sealed relationship to the interior of the sheath proximate to the second end, and the intermediate section of the sleeve being adapted to surround and coact in a sealed relationship with a portion of the limb.

  • Patent number: 5337068
    Abstract: A back-lighted color LCD display is formed by placing a single matrix of liquid crystal devices (LCDs) over a bank of red, green and blue fluorescent lamps. The LCD matrix is operated to sequentially form separate red, green and blue images synchronous with the illumination of the respective red, green and blue lamps. The flashing of the sequential red, green and blue images is perceived as a color image. The images are scanned, one line at a time, onto the LCD matrix. The bank of fluorescent lamps includes several lamps of each color which are arranged in parallel with the lines of the LCD matrix. The different lamps of each color are activated in synchronism with the scanning of the LCD matrix. Each LCD in the matrix includes a rapidly varying liquid crystal material, sandwiched between conductive plates. The electric field between the conductive plates may be controlled by a polysilicon thin-film transistor.

  • Patent number: 5334191
    Abstract: A system for welding tissue by irradiation with laser energy, includes a laser for generating a beam of laser energy and directing the beam toward the tissue so as to irradiate the region to be welded. The laser has a control input and is responsive to a control signal supplied to said control input to adjust the power of the beam of laser energy. An infrared sensor senses the temperature of the tissue in the region to be welded by sensing infrared radiation coming from this region. The sensor provides a sensor output indicative of the temperature. A computer control arrangement is responsive to the sensor output. The computer control arrangement supplies a control signal to said laser such that the region to be welded is heated to a predetermined temperature.

  • Patent number: 5331851
    Abstract: The invention relates to a method for measuring the working condition of muscles, and to a measuring and training system for measuring the working condition of muscles and muscle training. Muscles are loaded with mechanical devices, the working condition of muscles is measured with measuring equipment, and the obtained results are registered. According to the invention, from among a number of separate, independent muscle training devices, there is chosen one, whereby the muscles are loaded, and the working condition of muscles is measured by means of the sensors provided therein. The sensors of the training device are connected, by means of a connector element, to a data processing unit, and the chosen type of training device is identified to the data processing unit, whereafter the measuring program, corresponding to the training device in question, is activated.

  • Patent number: 5330842
    Abstract: A vestibule block or interior furnace wall utilized in a diffusion furnace for manufacturing semi-conductors, integrated circuits and the like, and which is made of refractory or ceramic material, is treated on its surface with a suspension of fine particulate of a glass frit composition comprising an alkali earth metal alumino silicate, and is thereafter heated above the transition temperature of the alkali earth metal alumino silicate. Vestibule blocks and interior surface walls which have been treated in the above-described manner are highly abrasion resistant on their surface, generate virtually no particulate matter under conditions of ordinary use in the semi-conductor manufacturing processes, and generate significantly less particulate matter when tested in an abrasion test against vestibule blocks of the prior art.

  • Patent number: 5324482
    Abstract: A pipette tip storage and dispensing system has a series of pipette tip holder cards each of which has a plurality of openings for holding a set of pipette tips extending partway through the openings in an upright orientation. The openings in each card match those in the other cards, and cards loaded with pipette tips can be stacked vertically with the pipette tips in one card extending into the open upper ends of the tips in the next adjacent card of the stack, to minimize storage space. An alignment device is arranged to hold the pipette tips in a card in a vertical orientation as the card is removed from the top of the stack and transferred to a pipette tip holder tray so that the pipette tips can be lowered into aligned openings in the holder tray with the card resting on the top wall of the tray.

  • Patent number: 5325449
    Abstract: A method for fusing two or more source images to form a composite image with extended information content and apparatus for forming the composite image from the source images is disclosed. Each source image is decomposed into a number of source images of varying resolution. The decomposed source images are analyzed using directionally sensitive operators to generate a set of oriented basis functions characteristic of the information content of the original images. The oriented basis functions for the composite image are then selected from those of the different source images and the inverse of the decomposition performed to construct the composite image. Apparatus for fusing two or more source images to form a composite image is also disclosed.

  • Patent number: PP8864
    Abstract: A new and distinct variety of plum tree which is somewhat remotely similar to the "Black Beaut" plum tree in that it produces fruit which are mature for harvesting and shipment approximately simultaneously with the fruit of the "Beaut" plum tree, but from which it is distinguished by having a greater regularity of bearing, due to the production of pollen, and wherein the fruit has a more uniformly dark purple skin coloration, a more balanced flavor and a smaller pit without a tendency to fragment.
