  • Patent number: 11125666
    Abstract: A hose to be evaluated is installed on a fixing frame in a preset shape, and a strain gauge and markers are attached to a surface of the hose. During a course of application of predetermined internal pressure to the hose, strain data is acquired using the strain gauge and an image of an external shape of the hose is captured using a camera device to acquire image data. Based on the strain data and the image data acquired, a change in the shape of the hose between a plurality of time points at identical internal pressure is determined. Such hose fatigue resistance evaluation method can determine changes in the degree of deformation of a hose over time due to repeated application of internal pressure.

  • Patent number: 11047728
    Abstract: A load weight and balance system has first sensors for providing a first output signal proportional to an available internal volume of an associated passenger luggage storage bin. Second sensors provide a second output signal proportional a weight of any luggage in the associated passenger luggage storage bin. Display devices provide a visual indication whether or not each passenger luggage storage bin is filled to capacity. A main display provides a visual indication of the storage status of all of the passenger luggage storage bins. A processor receives the signals from the first sensors and the second sensors, calculates whether or not each of the passenger luggage storage bins is filled to capacity and whether or not each of the passenger luggage storage bins is within a predetermined weight value, and determines whether or not the weight distribution of the passenger luggage storage bins in the aircraft is balanced.

  • Patent number: 11029177
    Abstract: A pressure compensated sensing system and methods for using the same are provided. The system can include a housing, a seal, an incompressible fluid, and sensing elements. The seal can be positioned within a housing cavity and divide the cavity into two portions. A first cavity portion can be sealed from the fluid environment by the seal and contain the sensing elements and the incompressible fluid. A second cavity portion can be in fluid communication with the fluid environment. The fluid environment can apply an external pressure to the seal that is opposed by an internal pressure of the sealed cavity applied to the seal by the incompressible fluid. When the internal pressure and the external pressure are different, the seal can move in a manner that changes the volume of the sealed cavity by an amount sufficient to equalize the internal pressure with the external pressure.

  • Patent number: 11022473
    Abstract: A sensor assembly is described herein that can automatically calibrate itself upon installation into an empty bin, eliminating the need to actually fill the bin to calibrate the level reading. The sensor will provide consistent measurement regardless of material properties (permittivity, density, temperature or moisture content). The capacitive nature of the sensor means that in some circumstances, it will sense the material through plastic/glass/fiber glass thereby allowing the sensor assembly to be mountable on the outside of a bin or container. The electrodes of the sensor system are designed to provide a continuous level reading.
