  • Patent number: 5682445
    Abstract: Optical fiber devices include optical fibers having grating portions with in-fiber gratings having optical characteristics which are changed by the use of strain inducing members. The strain inducing members are connected to optical fibers in such a way that the strain applied to an in-fiber grating in an optical fiber is greater than the strain in the strain inducing members. Basically, a given percentage change in a dimension of one of the strain inducing members causes a greater percentage change in a dimension of the grating portion. The strain inducing members may apply lengthwise or radial strain to the grating portion. Arrangements with mechanical coupling of two fibers using one or more strain inducing members are useful for producing equal strain in grating portions of two fibers for interferometer configurations or other applications.

  • Patent number: 5674813
    Abstract: The invention provides a method for preparing a layered structure made up of a plurality of thin films composed of different compositions, in which the method involves using a reactive co-evaporation technique to deposit a first thin film on a substrate using a first set of evaporation sources, and then depositing another thin film of a different composition on the first thin film, using a second set of evaporation sources that has no evaporation sources common with the first set of evaporation sources. In the method, the first thin film is deposited in a first deposition sub-chamber and the second thin film is deposited in a second deposition subchamber, both of which are part of a single vacuum chamber.

  • Patent number: 5655306
    Abstract: A vehicle mounted backing distance gauge is provided, in which a plunger, normally biased to an extended position, extends approximately ten inches behind the vehicle, and as the vehicle is backed toward an object such as a loading dock, the plunger comes into contact with the object and retracts into a casing mounted to the driver's side of the vehicle. The plunger has an internal beam that moves in concert with the plunger, and through the use of a bevel gear pair and a follower arm controllably moved by the forward end of the internal beam, an indicator sign is rotated or pivoted by a shaft coupled to one of the bevel gears from a first position parallel to the side of the vehicle and extending toward the rear of the vehicle, to a diametrically opposed position parallel to the vehicle, but extending toward the front of the vehicle.

  • Patent number: 5651786
    Abstract: A catheter uses a steerable outer catheter with an inner catheter rotatable and extendable with respect to the outer catheter. The outer catheter may be positioned within a patient's heart and a portion of the outer catheter may provide movement like that of a windshield wiper by manipulation of a spring. By combining the windshield wiper type movement with the extension and rotation of the inner catheter relative to the outer catheter, a large area within a patient's heart may be readily mapped for conduction tissue and be subjected to laser ablation if appropriate. Various configurations provide flexibility in relatively positioning of windows used to apply laser energy and ring electrodes used to sense conduction tissue. Some embodiments provide only mapping (no ablation) or with ablation by other then Various anchoring techniques are described.

  • Patent number: 5652538
    Abstract: The integrated circuit includes at least one conductance (6) which is adjustable by a digital control signal (17) which encodes steps in value for quantizing an exact value to within a fixed relative accuracy .DELTA.p. The conductance (6) includes elementary conductances which each define a step in value such that each elementary conductance is dimensioned so that a single level in value of the conductance (6) corresponds to two successive levels of the value of the digital control signal (17). If the result from the first of the two levels of value of the digital control signal (17) is a value which is lower, or respectively higher, than the exact value, the corresponding elementary conductance is enabled, or respectively disabled. Accordingly, the adjusted total value of the conductance (6) is equal to the exact value to within the same relative accuracy .DELTA.p, without oscillating between two values straddling this exact value.

  • Patent number: 5648659
    Abstract: To acquire both a scatter image and an emission image in nuclear medicine, it is chosen to detect the emission image by validating the radioactive events that occur in the nominal range of the radioactive marker chosen. For the scatter image, lower energy ranges are chosen, these ranges corresponding to the production of at least secondary or tertiary Compton photons. It is shown that it is possible, in this way, to reconstruct an artifact-free transmission image. This scatter image is used to correct the initially acquired emission image. It is shown that it is possible to acquire both images at the same time.

  • Patent number: 5644987
    Abstract: A process and apparatus for printing with a press at least one image by transfer of an electrostatic colorant vehicle between an intermediate transfer element and a printing carrier, including the steps of making the intermediate transfer element in the press by magnetically developing zones on a substrate, depositing a magnetic, insulating, and hardenable material on the substrate to constitute the zones, hardening the hardenable material, subjecting the hardenable material to an electrostatic charge in order to lend the zones an affinity for the colorant vehicle, and transferring the colorant vehicle to the printing carrier by directly contacting the intermediate transfer element to the printing carrier.

  • Patent number: 5646871
    Abstract: A process for systems analysis of a database non-agreement system using a set of gauges. Measurement of the state of a system. A gauge function, a threshold value and a recommendation are associated with at least one part of the gauges. Each gauge function returns a value which characterizes the state of the system analyzed and a recommendation based on the logical relationship between the value returned and the threshold value is emitted for the user of the system. The gauges for the analysis of a system are grouped into investigations. The process can be adapted to the analysis of any system by editing an ASCII data file which contains the list of gauges, of the designations of the associated functions, and of the associated thresholds and the associated recommendations. A graphic interface makes it possible to select the investigations to be applied to the system.

  • Patent number: 5644991
    Abstract: A pallet for transporting a load having a deck and two skids removably mounted under the deck for supporting the deck and screw jacks which make it possible to vary the height of the deck relative to the ground. The deck is capable of supporting the weight of the load when it is carried by the screw jacks. Right angle brackets fasten the load to the deck. Depalletization consists of removing the skids by raising the deck via the screw jacks, then lowering the deck and moving the load in horizontal translation. The invention applies most particularly to the transport of heavy, bulky or fragile objects such as cabinets of data processing machines.
