A power transmission belt includes a stacked body including a back surface layer disposed on a back surface side, an inner surface layer disposed on an inner surface side, and a tension member layer containing a tension member embedded between the back surface layer and the inner surface layer, in which the power transmission belt includes a sensor configured to detect a status of the power transmission belt, as at least a part of the stacked body.

A toothed belt includes at least one tension member and a plastics material matrix which at least partially encases the tension member. The at least one tension member extends in the plastics material matrix in a running direction and teeth of the toothed belt are formed transversely to the running direction in the plastics material matrix. The tension member is formed from an electrically conductive material and the plastics material matrix is formed from an electrically insulating material. The toothed belt has at least one electronic component which is embedded in the plastics material matrix and has at least one sensor which detects data on a condition parameter of the toothed belt. The at least one electronic component is coupled to the tension member via at least two voltage taps to tap a voltage induced in the tension member to supply the at least one electronic component with power.

Systems and methods for providing low-power sensing, identification, and sweep detection for items on a sensor mat are provided. Item detection sensors are provided in grid on a sensor mat. A first subset of the item detection sensors are sensed at a first time, and a second subset of the item detection sensors are sensed at a second time. The item detection sensors of the first and second subsets are chosen such that they span the surface of the sensor mat, and so that the sensors of the chosen subsets include all of the sensors of the mat after multiple sensing steps have been completed.

The invention relates to a sensor device for insertion and for measuring tension within a braided, plaited and/or laid line. The sensor device comprises an elongated sensor housing having an outer housing surface and an inner housing surface and at least one pressure sensor arranged inside the elongated sensor housing. The outer housing surface having a substantially elliptic or circular cross sectional area around the longitudinal axis of the sensor housing. Further, the at least one pressure sensor is configured to allow measurement, at least indirectly, of a pressure exerted on the outer housing surface. The invention also relates to a line sensor assembly for mooring of one or more structures, and a method of adjusting the tension in a line sensor assembly and the use of a line sensor assembly.

A calibration process for use in calibrating intelligent cable modules. A separate calibration load cell is provided. This device is placed in the load path for the cable on which the intelligent cable module is installed. The calibration load cell then establishes a communication link with the intelligent cable module. An iterative series of loading cycles are started. Tension data as measured by the calibration load cell is used to create a calibration curve. This calibration curve is used to correlate internal measurements made by the intelligent cable module against a desired value—such as cable tension.

The present invention relates to a crane having a boom at which at least one load receiving means is arranged in a raisable and lowerable manner, wherein an overload protection device has detection means for detecting the outreach and the load on the at least one load receiving means, and wherein a monitoring device for monitoring the overload protection device is provided and has determination means for determining a tensioning force holding the boom and/or induced in a guy cable. The invention furthermore also relates to a method for monitoring the overload protection device of such a crane. Provision is made in accordance with the invention that the monitoring device determines online in crane operation a tensioning torque from the continuously determined tensioning force, determines a lifting torque from the continuously detected outreach and the continuously detected load, determines a dead torque while making use of stored crane data, compares the sum of the named lifting torque and the named dead torque with the named tensioning torque and then, if a difference found in the comparison exceeds a tolerance threshold, emits an error signal and/or shutdown signal.

Systems and methods for evaluating the performance of an athlete using a strain gauge is described. In some embodiments, the measurement system comprises a strain gauge and a central processing device. The strain gauge can include a power source, an inertial measurement unit (“IMU”) comprising a load cell, a microcontroller, and a wireless communication module. The strain gauge can be configured to output strain data at a rate of at least 1kHz and the central processing device can be configured to receive the strain data transmitted from the wireless communication module.
