A transducer assembly includes a mounting base, a collar, a magnet, and a Hall effect sensor. The collar defines a bore and extends from a proximal end to a distal end. The proximal end is fixedly coupled with the mounting base. One of the magnet and the Hall effect sensor is disposed within the bore and fixedly coupled to the mounting base. The other of the magnet and the Hall effect sensor is fixedly coupled to the distal end of the collar. The Hall effect sensor is spaced longitudinally from the magnet and is configured to detect lateral deflection of the distal end of the collar. Methods are also provided.

A system and method of monitoring forces exerted at multiple locations on a mover includes multiple sensors, where each sensor is mounted at one of the locations. Each sensor detects an operating condition of the mover at the location on the mover at which it is mounted. The sensors may include accelerometers, strain gauges, or a combination thereof. Each strain gauge is mounted proximate to an area of interest on the mover. Each strain gauge generates a feedback signal corresponding to a deformation of the material measured at the location of the sensor. From the measured deformation of material, a force acting on the mover at the location of the sensor may be determined. The forces exerted at the different locations on the mover may be monitored in real time to determine bearing performance or monitored over a duration of time to observer changes in bearing performance over that duration.

Assisted racking of digital resistance includes detecting a state of a cable. A motor is mechanically coupled to the cable to provide resistance during an exercise by tensioning the cable. It further includes determining completion of the exercise based at least in part on the detected state of the cable. It further includes selectively removing resistance from the cable based at least in part on the determination that the user has completed the exercise.

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.

The present invention discloses a monitoring system of a cable laying state, comprising: a rotary connector, a composite steel cable and a monitoring system. Both ends of the rotary connector are respectively connected with a laid cable and the composite steel cable, wherein the rotary connector is provided with a tension sensor, a video sensor and an inertial navigation measurement module; and tensile force, video, and inertial navigation information are transmitted to the monitoring system through the composite steel cable. The monitoring system of the cable laying state disclosed by the present invention combines a video technology, a measurement technology and an inertial navigation technology and can monitor an environment in a pipeline, a cable core stress state and a three-dimensional coordinate of an actual path during a cable laying process in real time.

Deployable slackline systems are disclosed which can support a slackline at a desired height and nominal tension. The disclosed systems may maintain one or more slacklines and can adjust height and tension of individual slacklines while the slacklines are in use. The disclosed slackline systems are stowable; tensioning and termination assemblies of the slackline system can each fold into a compact housing having a height substantially less than a vertical range of motion of the slackline. The disclosed slackline systems can be implemented in aquatic or non-aquatic performance environments such as on cruise ships or other hospitality settings.

A system includes several load cells, each coupled to a lashing that secures shipping containers, accelerometer cells, each coupled to a shipping container at the top of a stack, and an inclinometer cell coupled to a cargo ship. The cells are configured to transmit data to a computer. All the cells comprise a processor programmed to acquire a time series of measurements and, preferably, decompose the time series into a sum of sinusoidal signals, each having a frequency and an amplitude. Alternatively, the computer can be programmed to decompose the time series. The computer is programmed to identify the signal components caused by the roll of the cargo ship or by resonances in shipping container stacks. The computer estimates cumulated damages caused by fatigue in the lashings and/or twist locks. The system is used to trigger alarms and/or schedule maintenance.

A robotic surgical system includes a controller, a surgical instrument supporting an end effector, and one or more connector members coupled to the end effector and movable to operate the end effector. Memory is operably coupled to the controller and is configured to maintain reference data of the one or more connector members. A sensor is secured to the one or more connector members and is disposed in electrical communication with the controller. The sensor is configured to register real-time data of the one or more connector members and communicate the real-time data to the controller. The controller is configured to compare the real-time data to the reference data and provide an output signal in response to a comparison of the real-time data to the reference data. A pair of connector members may be coupled to the end effector to impart three outputs.

A fall arrest system includes a line retraction device having a safety line, an energy absorber configured for connecting to a terminal end of the safety line, and a harness configured for connecting to the energy absorber such that the energy absorber is disposed between the terminal end of the safety line and the harness. The safety line is selected to have a predetermined mean breaking force with a first standard deviation, and the energy absorber is selected to have a predetermined mean deployment force with a second standard deviation. The mean breaking force of the safety line and the mean deployment force of the energy absorber overlap over an overlapping region of the first and second standard deviation. A ratio of an overlap mean force of the overlapping region to an overlap standard deviation of the overlapping region is less than or equal to 6.
