A belt monitoring system for an agricultural belt arrangement, the monitoring system including an agricultural belt having a magnetic element embedded therein and a sensor. The agricultural belt arrangement defines a proper belt alignment for the belt and moves the belt. The magnetic element is polarized so as to output a magnetic signal. The sensor is configured to detect, at a reference position, the magnetic signal outputted by the magnetic element. The monitoring system further includes a circuit configured to output a signal if, for example, the agricultural belt moves more than a predetermined amount through the agricultural belt arrangement without the sensor arrangement detecting the magnetic signal outputted by the magnetic element, a predetermined amount of time passes without the sensor detecting the magnetic signal, and the circuit determines the position of the magnetic element to be outside of a permissible positional range.

An apparatus for emitting a field comprising a core, a conductive winding with a first end, a second end, and an intermediate portion, where the conductive winding surrounds a portion of the core and is wound about a winding axis, a protrusion for aligning the apparatus where the protrusion is parallel with the winding axis, and a conductive connector extending from the conductive winding, wherein the conductive connector is electrically coupled with the conductive winding at the intermediate portion.

An apparatus for measuring a plate-shaped workpiece comprises a conveying device for conveying the plate-shaped workpiece in a conveying direction along a conveying path and first and second measuring devices including respective first and second drivers and respective first and second measuring rulers. Each of the first and second drivers is selectively couplable to and decouplable from a main surface of the plate-shaped workpiece. In a coupled state, the drivers are moveable together with the plate-shaped workpiece in the conveying direction and, in a decoupled state, are actively movable in a direction opposite to the conveying direction. The measuring rulers extend in the conveying direction such that the positions and/or movement distances of the drivers in the conveying direction are detectable. The first and second measuring rulers detect different regions of the conveying path of the plate-shaped workpiece in the conveying direction.

A system for measuring the length of the contact patch of a tire mounted on a wheel of a vehicle while the vehicle is traveling that includes a chassis, a light source, a light sensor, a data transmission unit, and a processor. The chassis is attached to the inner side of the tire, and the light source, the light sensor, and the data transmitting unit are attached to the chassis in a way that when the light source illuminates at a specific spot on the inner side of the tire the returning light is detected by the light sensor and the intensity of the returning light can be changed when that specific spot enters the contact patch and when exits the contact patch. The data transmitting unit calculates the length of the contact patch based on intensity changes of the detected light.

A smart belt and a control method thereof are provided, in which a belt device is provided, including a strap portion comprising a plurality of magnet patterns, a first sensor portion configured to sense one of the plurality of magnet patterns while the strap portion is being fastened to a buckle portion, and a controller configured to obtain a length of a waist circumference of a user that corresponds to the magnet pattern sensed by the first sensor portion. The belt apparatus may additionally include a clip portion connecting the strap portion with the buckle portion, and a second sensor portion configured to measure a tension exerted on the clip portion while the strap portion is being fastened to the buckle portion. The controller may correct the length of the waist circumference using a waist circumference correction value corresponding to the measured tension.

The present disclosure relates to chain monitoring systems and methods. In particular, the chain monitoring system is configured to mount onto a portion of a chain and measure one or more parameters associated with one or more characteristics of the chain. The measured parameters are processed by the chain monitoring system and/or transmitted to a remote system for analysis. The analysis may be used to determine a characteristic and/or change in the characteristic of the chain. In some examples, the characteristic is an elongation value associated with the chain, which can be transmitted to a networked system for analysis, display, and/or control. In some examples, a sensor can be employed to measure one or more characteristics of the chain. The sensor may include, but is not limited to, a strain gauge, an accelerometer, an optical, a sonic, and/or a magnetic sensor.

Disclosed are methods and apparatuses for analysis of synthetic ropes, cords, slings, cables and belts (collectively termed ropes) including but not limited to ropes for bearing loads as well as fiber optic cables. The ropes are provided with one or more elements for magnetic detection, wherein the magnetic detection elements each comprise a metal fiber or an appropriately treated synthetic fiber. The methods and apparatuses encompass detection of induced or residual magnetism or magnetic flux in the magnetic detection element(s), to sense for example lay length and/or damage, breakage or wear of the magnetic detection element(s), indicative of the condition of the rope.

A biological tissue inspection apparatus is disclosed. The biological tissue inspection apparatus comprises a stage and a probe. The probe comprises an optical imaging device, an optical interference detector, and a light guide. The probe acquires data regarding optical images and optical interference, through the optical imaging device and the optical interference detector. The stage or the probe moves such that a selected area of the inspection object is positioned in the FOV of the optical imaging device and of the optical interference detector. The light guide is configured such that illumination light from the optical imaging device and measurement light from the optical interference detector are coaxially emitted to the inspection object.

A system for measuring a conveyor belt includes a first detector fixed at a location along a path of a conveyor belt. A first signal generator is affixed at a first location of the conveyor belt such that the first signal generator is detectable by the first detector when the first signal generator is in range of the first detector. The first detector is configured to provide a first signal as the first signal generator approaches the first detector. The first detector is configured to provide a second signal as the first signal generator moves away from the first detector. A processor is in electronic communication with the first detector and configured to calculate a belt speed based on an elapsed time between the first signal and the second signal.
