Abstract:

A power sensor module suitable for automotive and other high volume applications combines speed sensing and torque sensing operations into a single unit. A magnetic speed sensor is utilized for speed sensing. A power measurement can be derived from torque and speed. Combining torque sensing and speed sensing within a single module instead of using separate modules for each allows for reducing redundancies and lowering cost.

International Classification:

G01M 15/00

US Classification:

731173

Abstract:

A torque sensor system and method. An automotive engine is located opposite a torque converter, such that a shaft extends from the engine and interacts with the torque converter. A target is located between the engine and torque converter. One or more torque sensors can be integrated with one or more position sensors for detecting a position associated with the shaft, wherein the torque sensor(s) and the position sensor(s) are integrated into a single torque sensor package to thereby provide enhanced sensing of the target in association with a rotation of shaft during an actuation of the engine.

International Classification:

H01L 41/08

US Classification:

310313R, 310344

Abstract:

A method and apparatus, wherein a die is attached to a supporting base structure utilizing a rigid bond adhesive for a SAW (Surface Acoustic Wave) sensor. A rigid bond adhesive with a preferably high glass transition temperature (Tg) can be applied directly between the die and the die supporting structure in a pattern to eliminate time dependent gradual stress effects upon SAW sensor. The rigid bond adhesive can then be cured, which results in a high yield strength and a high young's modulus. The supporting base and the die material comprise a same co-efficient of thermal expansion in order to avoid die displacement over temperature.

International Classification:

H02P 7/00

US Classification:

318432000

Abstract:

Many mechanical systems contain rotating parts used to transfer power from one part of the system to another. The system's efficiency and longevity can be increased by measuring the speed and loading of the rotating parts. Passive wireless sensors are ideal for instrumenting rotating parts because they require no connecting wires and no stored energy. The sensor measurements contain read errors when the stationary interrogation circuit and the rotating sensor are not ideally aligned. The read errors are a function of the angular offset between the stationary interrogation circuit and the passive sensor. As such, the read errors are deterministic. A measurement of the angular offset between the stationary interrogation circuit and the passive sensor is used to determine a correction factor that cancels out the read error to produce a compensated sensor signal.

US Classification:

701 42, 180446

Abstract:

A method and system for onboard zero offset compensation for ATV electric power assist steering (EPAS) torque sensor. An electric assist torque can be applied to an EPAS motor in a clockwise and a counterclockwise direction until a movement is generated in a steering column. A threshold value of torque signal generated by the torque sensor in both directions can be stored when the applied torque exceeds a reaction torque to cause acceleration of a shaft. The reaction torque can be determined under conditions such as, for example, when no one is holding the handle bars and the wheels are free from obstruction. The magnitude of the torque signals are approximately equivalent and an absolute magnitude of the torque signals falls below a general torque limit that can be set under ideal conditions with the ATV. Thereafter, an auto zeroing operation can be performed a number of times throughout the life of the ATV and the error due to offset drift of the sensor can be reduced.
