  • Patent number: 6314765
    Abstract: A method and apparatus for controlling the shape and position of a deformable object are described. At least a portion of an object is heated to a temperature sufficient to render the heated portion deformable by a force. An image profile of the heated portion of the object is obtained. A controller compares the image profile to a reference profile and produces an error image signal. Based on the error image signal, an instruction signal is generated. A force applicator responsive to the instruction signal applies a radial force to at least one distinct predetermined location on the heated portion of the object in response to the instruction signal to cause the heated portion of the object to conform to the reference profile. The invention is particularly useful in controlling the shape of an optical fiber preform.

  • Patent number: 6314779
    Abstract: A tool for reducing the diameter of the center conductor of a coaxial cable allowing it to mate with a smaller receptacle without the necessity of a reducer. The tool uses plural rollers within a housing to roll form the conductor as they rotate about it. Preferably the rollers are caged for alignment but bear on the inner surface of the housing. The housing thus resists the axial loads on the rollers and transmits the rotational drive force directly to the rollers allowing the roller cage to serve solely alignment purposes. The roller cage incorporates an extended nose designed to contact the dielectric portion of the cable, serving as a depth stop. An optional indicator sleeve is visible through openings in the housing and indicates the position of the roller cage within the housing. A small lead angle on the rollers causes them to self feed onto the conductor and to crawl rearward within the chamber which provide the indication of the length of conductor reduced.

    Abstract: An oxygen concentration detecting apparatus precisely and easily performs diagnosis of a limit current type oxygen sensor. The limit current type oxygen sensor has an oxygen concentration detecting element for outputting limit current proportional to the oxygen concentration and a heater for heating the detecting element. A CPU of a microcomputer controls energization of the heater to activate the oxygen sensor. The CPU calculates element resistance based on the voltage applied to the oxygen sensor and the current detected in the sensor. In a sensor diagnosis routine, the CPU determines whether preconditions for the diagnosis have been met. If all the preconditions have been met, the CPU executes the diagnosis. That is, the CPU determines whether the element resistance is within a predetermined range. If it is below the range, the CPU determines that the sensor has high element temperature abnormality.

  • Patent number: 6314802
    Abstract: The present invention provides a method and system for detecting engine misfire with an optimal compensation of the RPM signal in an internal combustion engine in which the data signal containing a plurality of groups of sample data points is generated. Each of the groups of sample data points represents a cylinder firing event. The data signal is then conditioned for misfire detection processing. The data engine cycle compensation vectors for the RPM zone is then multiplied to the sample data of the RPM. Each group of sample data points is processed using signal processing techniques and then mapped into a single mapped data point. The mapped data points are further processed and then compared to a misfire detection dynamic threshold. A misfire detection signal is then output if any of the mapped data points fall outside the dynamic threshold. The misfire detection system achieves high degree of accuracy through a signal processing and statistical detection technology.

  • Patent number: 6314804
    Abstract: A method of inserting an injector in a test head includes inserting the injector in a puck; aligning the puck beneath the test head; engaging a bottom of the puck with a floating cone assembly; raising the puck upwards towards the test head; and inserting a top portion of the injector into the test head. The floating locator cone assembly includes a floating locator cone mount; a ball thrust bearing assembly inserted in the floating locator cone mount; and a floating locator cone inserted in the floating locator cone mount on top of the ball thrust bearing. Use of the floating locator cone assembly allows the puck to center itself thereby allowing the injector to be properly aligned upon insertion in the test head. Proper alignment of the injector reduces false leak test readings and the consequent rejection of good injectors.

  • Patent number: 6314809
    Abstract: The invention uses coherent outputs from two or more Bose-Einstein condensates (BECs) to characterize the acceleration due to gravity. The condensates are created at two or more different heights in the gravitational potential. de Broglie waves are extracted from each of these condensates and are interfered at detector which is located below the lower condensate. In the same manner as an optical heterodyne experiment, interference of the two “atom laser beams” results in a beatnote whose frequency is given by the energy difference associated with each atom laser beam. This beat frequency is given by the frequency difference of the two atom laser beams and is proportional (via Planck's constant) to the energy difference of the interfering beams. This energy difference allows the force of gravity to be derived at a level of sensitivity approaching 10−14 g (where g is the acceleration due to gravity).
