A slide rail for a continuously variable transmission is disclosed that comprises at least one slide surface arranged for guiding a wrap-around mechanism that connects a first cone pulley pair to a second cone pulley pair of the continuously variable transmission to transfer torque therebetween. The slide rail includes at least one acceleration sensor arranged so that an acceleration of the slide rail perpendicular to the at least one slide surface can be detected by the acceleration sensor.

A vibration processing apparatus (10) includes: an acquisition unit (110) that reads, from a vibration information storage unit (112), information needed for detecting an abnormality in a belt conveyor (20), the information being, for example, first detection data indicating a result of detecting a vibration at a first point of the belt conveyor (20), and second detection data indicating a result of detecting a vibration at a second point on a downstream side of the first point of the belt conveyor (20); and a determination unit (120) that determines that an abnormality occurs in the belt conveyor with a necessary condition or a necessary and sufficient condition that a result of comparing the first detection data and the second detection data satisfies a first reference.

Systems and methods for measuring web tension distribution in roll-to-roll processes, for example, such as R2R processes employed in the fabrication of printed devices. Such systems and methods entail a web that travels between first and second rollers in a longitudinal direction of the web, inducing tension in the web in the longitudinal direction thereof such that tension is present in a flexible substrate of the web between the first and second rollers, and operating the system to determine an average tension and linear variation of tension present in the flexible substrate resulting from the tension induced in the web inducing a nonuniform tension distribution in the flexible substrate between the first and second rollers. The systems and methods utilize one or more devices that induce deflection in the web between the first and second rollers.

A system and method for performing structural health monitoring on a structural element while it remains in service and experiences normal loading. The energy input to the element will be the normal and random energy inputs the element sees in service. The inventive system places an intelligent module at one or more points along the length of the structural element. The inventive system collects mass data from multiple modules on multiple elements. The system then applies machine learning or artificial intelligence techniques to detect changes in the measurements received from one or more modules. This approach reduces or eliminates the need to provide calibrated input energy. The invention preferably provides the ability to determine the condition of one element or sub-element under measurement relative to other elements.

An improved system for monitoring drive members in a belt-driven application during installation and during operation and for detecting common failure modes in belt-driven equipment is disclosed. Sensors are positioned within or proximate the motor housing to detect vibrations on the belt or in the electric machine. The vibration signals are used to monitor operating conditions and/or to identify the failure modes in belt-driven equipment. The vibration signals may be used, for example, to determine tension on a belt, detect either a static or dynamic force applied along the belt, a misalignment between a pulley and the belt, or a shock load applied to the belt during operation. By monitoring the various operating conditions of the belt-driven equipment, a controller may identify an existing failure mode or predict a premature failure mode.

A resonator is suitable for reducing or suppressing a force transmitted by a vibrating portion of the resonator to a support part. To this end, the vibrating portion includes two extensions which are each meander shaped such that two segments of each extension have respective speed components that are oriented in opposite directions. Such a resonator, which is balanced, can advantageously be used within a rate gyro or a force sensor.
