Abstract: The present invention discloses a cable force identification algorithm considering semi-rigid constraints on both ends. The present invention only needs the basic parameters such as length and mass per unit length of a cable and then adopts a modal identification algorithm such as stochastic subspace method and frequency domain decomposition method to process signals collected by the acceleration sensor, and thus obtains the corresponding first natural frequency and mode shapes, and the cable force can be solved without obtaining any other data in advance. The present invention simplifies the cable to an equivalent single-degree-of-freedom system, modifies the first natural frequency of the cable through the mode shape of modal identification, avoids the cable force identification error caused by the change of the boundary mechanical characteristics of the cable, improves the efficiency and accuracy of cable force monitoring, has good application prospect in real-time monitoring of cable force of cable-stayed structure.

Abstract: The disclosed embodiments relate to systems and methods for a surgical tool or a surgical robotic system. One example system for detecting disengagement of a surgical tool, includes an end effector connected to and driven by cables of a tool driver, sensors configured to detect forces associated with the cables, and one or more processors. The one or more processors identify cable tensions derived from forces detected by the sensors, compare the tension to a threshold tension value, calculate a velocity norm value based on a vector including the velocity value for each of the cables, compare the velocity norm value to a statistic velocity threshold, and identify a disengagement of at least one of the cables based on the first comparison and the second comparison.

Abstract: A tension monitoring device that attaches or clamps onto to a tensioned cargo load securing strap and wirelessly communicates the tension level to the driver via a remote device, such as a mobile smartphone. One or more devices may be installed on a vehicle or trailer to be simultaneously monitoring the tension conditions during transit. The tension signal from the device is received and processed by the mobile smartphone application to display the real-time tension relative to unsafe levels and transmit alerts to the driver when an unsafe or undesired condition occurs. The tension monitoring device includes an electromechanical sensor and microprocessor, powered by a battery, and packaged inside two hinged weatherproof housings for the ability to clamp onto a tensioned cargo strap.

Abstract: 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.

Abstract: 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.

Abstract: The present invention relates to a method for determining the compressive tensile force acting on a fuel cell stack due to at least one tensioning element. Thereby, the compressive tensile force is the overall tensile force compressing the fuel cell stack. This is determined according to the invention by means of acoustic measurements on vibratable sections of the tensioning elements. The subject matter of the invention also includes a data processing program for carrying out the method according to the invention along with the use of a smartphone for carrying out the method according to the invention.

Abstract: A method is provided for identifying or authenticating an object. The method includes vibrating the object at a plurality of frequencies. The vibrations from the object are sensed at each of the plurality of frequencies using an accelerometer. A vibration profile of the object is generated using the sensed vibrations. The generated vibration profile is then compared to a stored vibration profile. It is determined if the generated vibration profile matches the stored vibration profile. A match indicates that the object has been identified or authenticated. In another embodiment, an object capable of implementing the method is provided. In another embodiment, the object may include a replaceable accessary. In this case, the initial and generated vibration profiles may be created with the replacement accessary attached to the object. A match of the generated and initial vibration profiles indicates that the replaceable accessary is authentic.
