Devices And Methods For Detecting Rates Of Change Of Torque

US Patent:
8438937, May 14, 2013
Filed:
Nov 16, 2010
Appl. No.:
12/946887
Inventors:
Ivan J. Garshelis - Dalton MA, US
Ryan J. Kari - San Diego CA, US
Stijn P. L. Tollens - San Diego CA, US
International Classification:
G01L 3/00
US Classification:
73862333, 73862335, 73862325, 702 43
Abstract:
Sensors for outputting signals indicative of a rate of change of torque experienced by a magnetized member in response to a change in torque experienced by the member are described. Such sensors include at least one sense element capable of detecting a change in a magnetic parameter of a magnetized region of the member positioned proximate to the sense element in response to a change in torque applied to the member. Devices for detecting and/or measuring rates of changes in or of torque that employ one or more of these sensors are also described, as are various applications for such devices.

Devices And Methods For Detecting Rates Of Change Of Torque

US Patent:
2008024, Oct 9, 2008
Filed:
Jan 5, 2008
Appl. No.:
11/969897
Inventors:
Ivan J. GARSHELIS - Dalton MA, US
Ryan J. KARI - San Diego CA, US
Stijn P.L. TOLLENS - San Diego CA, US
International Classification:
G01L 3/14
H02N 11/00
US Classification:
7386227, 73862193, 290 1 R
Abstract:
Sensors for outputting signals indicative of a rate of change of torque experienced by a magnetized member in response to a change in torque experienced by the member are described. Such sensors include at least one sense element capable of detecting a change in a magnetic parameter of a magnetized region of the member positioned proximate to the sense element in response to a change in torque applied to the member.

Devices And Methods To Enhance Accuracy Of Torque Sensors

US Patent:
2018017, Jun 21, 2018
Filed:
Dec 13, 2017
Appl. No.:
15/841266
Inventors:
- San Diego CA, US
Ryan J. KARI - Encinitas CA, US
International Classification:
G01L 25/00
G01L 3/14
G01L 3/10
G06F 17/00
H01L 41/12
Abstract:
This invention concerns torque sensor systems and methods that computationally compensate in real-time for hysteresis in signals output from sense elements that are indicative of a torque, including a time-varying torque. In preferred embodiments, temperature effects can also be compensated for by such methods and systems.

Devices And Methods To Stimulate Motion In Magnetoelastic Beams

US Patent:
2018016, Jun 14, 2018
Filed:
Dec 8, 2017
Appl. No.:
15/836765
Inventors:
- San Diego CA, US
Ryan J. KARI - Encinitas CA, US
International Classification:
G01L 1/12
H01L 41/12
G01H 13/00
Abstract:
This invention concerns devices, systems, and methods to induce motion in cantilevers for actuation and sensing applications. Motion is induced by applying current to a ferromagnetic, magnetostrictive cantilever subject to bending stress, and hence strain (deflection), having both elastic and magnetoelastic components. The applied current creates a magnetic field that reorients the magnetoelastic strain component, changing the total strain and thus the total deflection. Changing deflection can be harnessed for actuation or work. Moreover, considering both static and dynamic deflection, measureable parameters that are associated with beam deflection, vibration frequency, and/or amplitude can be measured.
