Patent number: 7525238Abstract: The invention describes a sensor comprising an element package 2 including piezoelectric elements with an upper area 6 and a lower area 7. A preload sleeve 3 surrounds the said upper area 6 of the said element package 2, while an insulation sleeve 1 sits between the upper area 6 of the said element package 2 and the said preload sleeve 3. An outer housing 4 partially or fully surrounds the said preload sleeve 3 and the lower area 7 of the said element package 2. An insulation part 5 sits between the said lower area 7 of the element package 2 and the said outer housing 4, whereas the said upper area 6 of the said element package 2, the said insulation sleeve 1 and the said preload sleeve 3 have conical shapes and have conforming surfaces. Due to the conical size of the insulation sleeve 1, the load during a shock measurement is distributed on a larger surface area resulting in a reduced compression of the said insulation sleeve. Thereby, the maximum range of the sensor is increased.Type: GrantFiled: January 25, 2006Date of Patent: April 28, 2009Assignee: Kistler Holding AGInventors: John M. Kubler, Andrew Paul Cook

Patent number: 5512794Abstract: An accelerometer having a pair of piezoplates and masses compressed to a center post by a bolt through bores in the center post, piezoplates and masses without mechanical or electrical contacting the piezoplates or the center post. A symmetrical arrangement includes opposed pairs of piezoplates separated by the center post or two pairs of piezoplates separated from each other by center post. Two bolts through orthogonal bores in a single center post or two perpendicular center post provide two and three axis of force sensing. Either linear or angular acceleration can be sensed. Two orthogonal mounting bores in the housing allows adjustment of the sensing axis.Type: GrantFiled: November 25, 1992Date of Patent: April 30, 1996Assignee: Kistler Instrumente AGInventors: John M. Kubler, Michael D. Insalaco

Patent number: 5009106Abstract: The shock resistance of an accelerometer for the measurement of an axial acceleration, having a sensing part consisting of an electromechanical beam, a spacer and a beam carrier can significantly be improved by making the two sections of the oscillating beam of unequal lengths and by providing the beam with a length between 8 mm and 11 mm and a width between 2.5 mm and 6.5 mm at a thickness of 0.6 mm. That way an optimum relationship between measuring sensitivity and shock resistance of the accelerometer will be reached.Type: GrantFiled: July 6, 1989Date of Patent: April 23, 1991Assignee: Kistler Instrumente AGInventors: John M. Kubler, Michael D. Insalaco

Patent number: 4771637Abstract: An accelerometer (50, 80, 90) provided with a plurality of mounting means for selectively mounting the accelerometer on a test structure. The mounting means include a magnet (64 or 96) carried by the accelerometer (58, 60), a threaded aperture (62) in the housing capable of receiving a mounting stud, and a planar external surface (66, 68; 82; or 94) on the housing, which surface is capable of being secured to the test structure by an adhesive or wax.Type: GrantFiled: March 18, 1987Date of Patent: September 20, 1988Assignee: Kistler Instrument CorporationInventor: John M. Kubler

Patent number: 4131020Abstract: A one-piece support frame is used to support a pair of capacitor plates and a lightweight longitudinally reinforced pendulum having a paddle on one end. The paddle is positioned midway between the capacitor plates forming a pair of capacitors. Attached to the pendulum is an axle which in turn is supported between two flexures by means of jeweled pivoted bearings. The ends of the flexures are rigidly secured to the support frame, and a desired pressure of the bearings against the axle is maintained by means of adjustment screws. Also attached to the pendulum is a torque coil which interacts with a magnetic assembly, secured to the support frame, to restore the paddle to the midpoint between the capacitor plates when the pendulum has been subjected to an acceleration force.Type: GrantFiled: July 6, 1976Date of Patent: December 26, 1978Assignee: Sundstrand Data Control, Inc.Inventors: Hans W. Hugli, John M. Kubler

Patent number: 4094199Abstract: In order to facilitate construction of a compact, lightweight servoed accelerometer with capacitive pick-off, a one-piece support frame, adapted to be inserted within a cylindrical housing, is used to support a pair of capacitor plates and a lightweight longitudinally reinforced pendulum or seismic mass having a paddle on one end. Attached to the pendulum is an axle which in turn is supported between two flexures by means of jeweled pivoted bearings. Also attached to the pendulum is a torque coil which interacts with a magnetic assembly, secured to the support frame, to restore the paddle to the midpoint between the capacitor plates when the pendulum has been subjected to an acceleration force.Type: GrantFiled: July 6, 1976Date of Patent: June 13, 1978Assignee: Sundstrand Data Control, Inc.Inventors: Frederick V. Holdren, Hans W. Hugli, John M. Kubler, Martin E. Larson, Michael M. Van Schoiack
