Performance Measuring System And Method For Analyzing Performance Characteristics Of Rotating Shafts
View pageUS Patent:
6672169, Jan 6, 2004
Filed:
May 20, 2002
Appl. No.:
10/152082
Inventors:
Mark Clymer - Mystic CT
Edward April - Mystic CT
Edward April - Mystic CT
Assignee:
Clymer Technologies, LLC - Mystic CT
International Classification:
G01N 2900
US Classification:
73660, 73643, 73650, 73862321
Abstract:
A performance measuring system for a rotating shaft comprises a first annular support assembly to be coupled adjacent to a first end of a rotating shaft inwardly of associated shaft bearings. A second annular support assembly is to be coupled adjacent to a second end of a rotating shaft inwardly of associated shaft bearings. A third annular support assembly is to be coupled to the rotating shaft between the first and second support assemblies. A laser source is mounted on the first annular support assembly. A laser detector is mounted on the second annular support assembly. First and second magnetic sensors for detecting the Earths magnetic field are mounted respectively on the first and second annular support assemblies. An accelerometer is mounted on the third annular support assembly for generating a fourth detection signal.
Inductive Sensor
View pageUS Patent:
6882143, Apr 19, 2005
Filed:
Apr 4, 2003
Appl. No.:
10/408067
Inventors:
Mark Clymer - Mystic CT, US
Edward April - Mystic CT, US
Edward April - Mystic CT, US
Assignee:
Clymer Technologies, LLC - Mystic CT
International Classification:
G01P003/48
US Classification:
324174, 32420715
Abstract:
In an inductive sensor a ferrous core is provided and has generally opposed first and second ends. A winding assembly surrounds the core. First and second magnets are coupled to the first and second ends of the core and are oriented relative to one another so that like magnetic poles are opposing one another along a length defined by the core.
3-Axis Magnetic Angular Orientation Sensor

20040017192, Jan 29, 2004
Filed:
Apr 15, 2003
Appl. No.:
10/413951
Inventors:
Mark Clymer - Mystic CT, US
Edward April - Mystic CT, US
Edward April - Mystic CT, US
Assignee:
Clymer Technologies, LLC - Mystic CT
International Classification:
G01B007/30
G01B007/14
G01B007/14
US Classification:
324/247000, 324/207250, 324/207210
Abstract:
An orientation sensor includes a sensor body. At least four magnetic sensors are coupled to the sensor body. The sensors are positioned in a non-planar arrangement, one relative to the other. A processor is in communication with the magnetic sensors. The processor is programmed to compute, based on signals generated by at least three of the sensors, the magnitude of a vector oriented in a direction substantially coincident with an inclination direction of a magnetic field in which the sensor is located.
Low Cost Miniature Vector Sensor

Applied Physical Sciences Corp. - Groton CT
International Classification:
G01P 15/08
G01P 15/09
G01P 15/09
US Classification:
7351428, 7351434
Abstract:
Low cost miniature vector sensors are provided. An acoustic vector sensor is provided that comprises at least one accelerometer to measure at least one component of acoustic particle acceleration, wherein the at least one accelerometer has a resonant frequency within a measurement band of the acoustic vector sensor. In addition, a method is disclosed for measuring an acoustic signal. The method comprises the steps of configuring an array of acoustic vector sensors comprised of at least one accelerometer to measure at least one component of acoustic particle acceleration; operating the at least one accelerometer at a resonant frequency within a measurement band of the acoustic vector sensor; and generating a voltage using one or more of the acoustic vector sensors representative of the acoustic signal as the acoustic signal propagates past the array. The voltage optionally indicates a bearing of the acoustic signal.
Gearless Mechanical Transmission
View pageUS Patent:
54434289, Aug 22, 1995
Filed:
Apr 29, 1994
Appl. No.:
8/235356
Inventors:
Edward April - Mystic CT
Martin April - Mystic CT
Martin April - Mystic CT
Assignee:
April Engineering Corporation - Mystic CT
International Classification:
F16H 2300
US Classification:
475163
Abstract:
A gearless mechanical transmission includes a housing which supports a high-speed shaft and a low-speed shaft along a main rotational axis. The housing also includes a precession link therein fixed for rotation about the high-speed shaft at an angle skewed with regard to the main rotational axis. A first cam surface is associated with the housing, a second cam surface with the low-speed shaft and a third and fourth cam surface with a precession link. Cam follower elements include rollers which establish rolling contact between the first and third and second and fourth cams respectively.
