Patent number: 5850041Abstract: The invention is a method and apparatus for controlling the vibration modes of a vibratory rotation sensor (VRS) comprising a resonator and a housing which together serve as the ground potential reference. The resonator has a surface with a conductive region and the housing has a plurality of attached electrodes positioned opposing the conductive region on the resonator. The parameters of the resonator standing-wave vibration pattern are determined by feeding an ac sensing signal to the conducting region on the resonator and obtaining one or more vibration signals while the electric potential of the conductive region on the resonator is maintained within 100 millivolts of ground. Each vibration signal is a replica of the ac sensing signal with amplitude modulation which is a periodic function of the distance from a point in the conducting region of the surface of the resonator to an opposing housing electrode. The frequency of the amplitude modulation is the vibration frequency of the resonator.Type: GrantFiled: March 21, 1997Date of Patent: December 15, 1998Assignee: Litton Systems, Inc.Inventors: Lalit Kumar, Michael J. Foster, Thomas A. Bittner

Patent number: 5604311Abstract: A monolithic Coriolis rate sensor includes a first member and a vibration generator that causes the member to vibrate along a first direction. At least one other member is mechanically coupled to the first member so that orthogonal vibrational modes are coupled to the other member when the members are rotated about a rotation axis. The vibrational mode coupling occurs as a result of the Coriolis effect. A vibration sensor is used to sense the orthogonal vibrational modes, the amplitude of which determines the rate at which the members are rotated. In a preferred embodiment, a central and two transverse end members with substantially equal resonant frequencies are mechanically coupled to form an "I"-shaped structure. The center member is vibrated at its resonant frequency, and orthogonal vibrational modes are coupled to the end members when the structure is rotated about a rotational axis that is orthogonal to both vibration directions.Type: GrantFiled: June 7, 1995Date of Patent: February 18, 1997Assignee: Litton Systems, Inc.Inventors: Lalit Kumar, Arthur R. Voros

Patent number: 5585732Abstract: A system for the detection of knots and voids in wood or lumber employs opposed arrays of capacitor plates. The presence of knots and/or voids is detected based on changes in the dielectrical response produced in the electrical fields defined by the opposed capacitor plate arrays. A software system delineates specific knot and void defects determined. Wood or lumber strength can further be estimated by comparing a sensed dielectric value in a clear portion of the lumber or wood with an established dielectric response value for wood of known density. Employing an appropriate correlation factor the relative wood density, coupled with knot/void location and size, permits an estimate of over all wood strength.Type: GrantFiled: June 7, 1995Date of Patent: December 17, 1996Assignee: Mississippi State UniversityInventors: Philip H. Steele, Lalit Kumar

Patent number: 5303179Abstract: A circuit that electronically simulates a capacitor includes a differentiator and a current source. In the preferred embodiment, the differentiator includes a differentiating gain amplifier that produces an output signal in response to an applied input signal, with the output signal being proportional to the time rate of change of the input signal. The differentiator further includes a variable inverting gain stage that produces a reference signal that has a desired phase relationship with respect to the input signal, such as a ninety degree leading phase for sinusoidal input signals. The variable gain stage is also used to provide for different simulated capacitance values, and to compensate for variations in the differentiator fixed value component. The current source is preferably a high output impedance current source such as a Howland current pump.Type: GrantFiled: January 3, 1992Date of Patent: April 12, 1994Assignee: Simmonds Precision Products, Inc.Inventor: Lalit Kumar
