  • Patent number: 5475774
    Abstract: In a optical fiber coil arrangement for use in rotation sensors, for example, errors resulting from axial and/or radial time varying temperature gradients can be minimized or substantially eliminated by employing reverse quadrupoles for the sensor coil. One of the quadrupoles is wound in a + - - + winding configuration. However, the next adjacent quadrupole is wound in a - + + - winding configuration. This reverse quadrupole arrangement substantially eliminates radial time varying temperature gradient dependent errors and reduces axial time varying temperature gradient dependent errors. The axial time varying temperature gradient dependent errors can be substantially eliminated by winding a reverse octupole arrangement. Accordingly, a reverse octupole arrangement is wound with a + - - + - + + - - + + - + - - + winding configuration.

  • Patent number: 4968909
    Abstract: A compact torque motor providing bi-directional, limited angle reactionless torque to opposed structures. A motor (10, 150) includes an X-shaped core (12), and first and second pole pieces (14 and 16), which are disposed at opposite sides of the core. Two opposed legs on the X-shaped core (12) comprise a first core section (18), which is transverse to a similar second core section (20). A first electromagnetic coil (22) is formed on the first core section and a second electromagnetic coil (24) on the second core section. When the first and second electromagnetic coils are alternately energized, tabs (38, 40, 44, and 46) disposed approximate the ends of the first and second pole pieces are attracted to the resulting magnetic poles (26 and 28, 30 and 32), causing the pole pieces to counter-rotate back and forth about a central axis (48). Magnetic flux developed by the first and second electromagnetic coils is conveyed through the tabs and the first and second pole pieces between the opposite magnetic poles.

  • Patent number: 4947164
    Abstract: A wind shear warning system monitors the flight path of an aircraft and wind shear in the vicinity of the aircraft and generates an advisory or cautionary message for the pilot based both on the magnitude of the wind shear and the flight path of the aircraft. When the aircraft is flying a normal flight path, a wind shear warning is generated only when relatively high negative wind shears are present. If the flight path of the aircraft is not normal, for example, if the aircraft is below the glide slope or descending too rapidly, a cautionary alert is given at lower values of wind shear. The alert or warning is selected to provide the pilot with information defining the nature of the hazard or potential hazard being encountered.

  • Patent number: 4929860
    Abstract: A technique is described for tailoring the configuration of electrodes on a piezoelectric beam such that the tendency of the beam to vibrate in a predetermined flexure mode is enhanced. The mode has a predetermined longitudinal strain versus longitudinal position profile. At least two electrodes are mounted on the beam, and the configuration of at least one electrode varies as a function of longitudinal position, such that when a voltage difference is applied between the electrodes, the longitudinal force produced by the electrodes, as a function of longitudinal position, approximates the longitudinal strain versus longitudinal position profile. The configuration may be varied by varying the width of the electrode or the position of the electrode on the underlying beam surface.

  • Patent number: 4912990
    Abstract: A vibrating beam force transducer that can be realized in a silicon micromachined device such as a micromachined accelerometer. The transducer includes a beam having a longitudinal axis, and a drive circuit electrically coupled to the beam for causing the beam to oscillate at a resonant frequency that is a function of a force applied along the longitudinal beam axis. The drive circuit provides an electrical current to the beam, and the beam, or a conductive portion thereof, conducts the current along a path that includes an axial component parallel to the longitudinal axis. A magnetic field is created intersecting the axial component, such that the electric current interacts with the magnetic field to produce a force that causes the beam to oscillate at the resonant frequency. In a preferred embodiment, the transducer has a double ended tuning fork configuration, and the current path extends along one beam and back along the other beam.

  • Patent number: 4901586
    Abstract: A dual vibrating beam force transducer having an electrostatic drive system. The transducer comprises a body having first and second generally parallel beams, coupled together at their ends. First and second electrodes are positioned adjacent to but not in contact with the respective beams. A drive circuit causes an oscillating voltage to be applied to the electrodes. The beams are thus subjected to electrostatic forces that cause the beams to oscillate in a vibration plane containing both beams. The mechanical resonance of the beams controls the oscillation frequency, such that the frequency is a function of a force exerted along the beams. An embodiment is also described in which the drive means is coupled directly to one of the beams.

  • Patent number: RE33401
    Abstract: The invention provides independent guidance and monitoring to be integrated into an MLS landing system and also provides a scaled-down MLS landing guidance system useable at small airports. In both cases an added fixed beam precision guidance system is integrated into the MLS time sequence format. The fixed beam guidance system is based upon the concept of using paired fixed overlapping beams, sequentially radiated by different fixed antennas. One pair is oriented to left and right of the centerline of the runway, and the other pair is oriented above and below the desired glideslope. The first set of paired beams overlap at the centerline of the runway in such a manner that an aircraft approaching exactly on centerline will intercept equal signal intensities to indicate an on-course approach.
