A torque sensor, torque transducer or torque meter is a device for measuring and recording the torque on a rotating system, such as an engine, crankshaft, gearbox, transmission, rotor, a bicycle crank or cap torque tester. Static torque is relatively easy to measure. Dynamic torque, on the other hand, is not easy to measure, since it generally requires transfer of some effect (electric, hydraulic or magnetic) from the shaft being measured to a static system.

Detecting driver grip on steering wheel
ActiveUS8909428B1High measurement accuracyImprove accuracySteering initiationsDigital data processing detailsElectricityDriver/operator
Aspects of the disclosure relate generally to determining by what degree a driver is gripping a steering wheel. In one example, a computer may send an electrically assisted power steering system (EPS) motor an excitation command to move. The EPS motor may respond by moving a flexible coupling between the steering wheel and the EPS motor. This may cause a corresponding movement at the steering wheel. A torque sensor may generate pattern data by monitoring the flexible coupling during the movement. The EPS motor may generate system position data for the entire steering system, for example, from the tires to the steering wheel. The pattern data and the system position data may be compared by the computer to determine the degree of grip. In this regard, the computer may determine the degree of a driver's grip without the need for additional sensors.

Gas turbine engine output torque is sensed using a reference torque sensor, and gas turbine engine output shaft rotational speed is sensed. Gas turbine engine output torque is calculated from the sensed gas turbine engine output shaft rotational speed. The sensed gas turbine engine output torque is compared to the calculated gas turbine engine output torque to determine if the reference torque sensor is operating properly. The gas turbine engine is controlled at least partially based on the sensed gas turbine engine output torque if the reference torque sensor is determined to be operating properly, and is controlled at least partially based on the calculated output torque if the reference torque sensor is determined to be not operating properly.

ActiveCN102614066AEasy to useSmall volumeChiropractic devicesComputer-assisted treatment prescription/deliveryPresent methodAthletic training
In respects of limitations and problems of motor function training devices, the present invention provides a wearable and convertible device and a method for controlling combined motor function training. This device integrates the functions of both passive stretching function in the existing CPM devices and additional active assistive training function. Without a force / torque sensor element in the device, the present passive stretching control can still be adapted to hypertonia (high muscle tone or stiffness of joints) of the limb, and the present active assistive control can still be implemented for enhancing voluntary active movement from patients. With such present method, much more applications of active assistive training are supported at substantially no additional cost. On the other hand, the safety of such stretching devices without using force / torque sensor is improved, which assists in increasing the efficiency of the device of the present invention.

Individual cylinder controller for four-cylinder engine
A generic technique for the detection of air-fuel ratio (or torque) imbalances in a 4-cylinder engine equipped with either a production oxygen sensor or a wide-range A / F sensor (or a crankshaft torque sensor) is developed. The method is based on a novel frequency-domain characterization of pattern of imbalances and its geometric decomposition into four basic templates. Once the contribution of each basic template to the overall imbalances is computed, templates of opposite direction are imposed to restore air-fuel ratio (or torque) balance among cylinders. At any desired operating condition, elimination of imbalances is achieved within few engine cycles. The method is applicable to current and future engine technologies with variable valve actuation, fuel injectors and / or individual spark control.
