A bearing device includes a bearing having an inner ring and an outer ring, at least one of the inner and outer rings being capable of rotating concentrically relative to the other ring. A fiber optic sensor includes an array of optical strain gauges mounted on the inner ring or on the outer ring of the bearing and an optical interrogator is configured to measure the deformations of the inner ring or the outer ring from the optical strain gauges. A command device commands the optical interrogator, a first determining device determines a statistical parameter from random samples of measurements, and a second determining device determines the load acting on the bearing from the statistical parameter and a predetermined relationship between the statistical parameter and the load.

Bearing device and method for determining a load on the bearing device

A communication device including one or more processors configured to perform a radio measurement to obtain a reception metric; identify a potential power reduction from a plurality of power reductions; scale the reception metric to compensate for the potential power reduction to obtain a reduced reception metric; and select a transmit power or a transmit repetition count for a radio frequency transceiver based on the reduced reception metric.

Methods and devices for narrowband communications

A communication device includes a measurement engine configured to perform a radio measurement to obtain a reception metric, a power reduction database configured to identify a potential power reduction from a plurality of power reductions, a metric scaler configured to scale the reception metric to compensate for the potential power reduction to obtain a reduced reception metric, and a transmit controller configured to select a transmit power or a transmit repetition count for a radio frequency transceiver based on the reduced reception metric.

A method for digital processing of vibration signals from rolling bearings in rotating machines is presented, allowing subsequent fault detection with high reliability. A linear, adaptive filter is applied to the acquired vibration signal and iteratively tuned to increase the statistical asymmetry of its output. In this process, the filter removes phase- and amplitude distortion from underlying fault impulses. Furthermore, suppression of sinusoidal disturbances is simultaneously achieved with high robustness to measurement noise. The result is a processed signal from which rolling bearing defects are more easily detected.
