摘要： A rubber cleat is instrumented with two triaxial accelerometers to measure the multi-directional response of the cleat due to the forces within the tire footprint of a ground vehicle. The cleat data is used to detect faults in the front and rear suspension in addition to the wheel tire despite variability in the data. This offboard diagnostic technique is proposed to enable condition-based maintenance.

摘要： Apparatuses and methods are disclosed for determining whether a structure of bonded layers includes locations where the layers are weakly bonded. Embodiments include evaluating the frequency response of the structure in response to vibrational inputs. Alternate embodiments include evaluating the non-linear response of the structure using a modal analysis. Further embodiments include obtaining the vibrational information with an accelerometer contacting the structure, while additional embodiments include exciting the structure with an impact force, which may be applied at multiple locations on the structure's surface. Still further embodiments include performing a MAC, COMAC, and/or FRF analysis. Still other embodiments include varying the amplitude of the input vibration. Additional embodiments locate the areas of weakened bonding. Still other embodiments include methods and apparatuses for simulating a laminated structure with defective bonding, such as kiss bonding.

摘要： Apparatuses and methods for determining one or more performance related characteristics (such as state of charge and/or health) of one or more electrochemical cells that store and release electrical energy are disclosed. Embodiments include pressure and/or temperature sensors that sense a change in pressure resulting from the tendency of the electrochemical cell to change volume and/or the temperature of the one or more electrochemical cells as the electrochemical cell(s) are charged or discharged. Alternate embodiments include one or more calculating members that receive pressure and/or temperature information from the pressure and/or temperature sensing members and calculate a performance related characteristic of the electrochemical cell. Still further embodiments include determining one or more performance related characteristics of an electrochemical cell by sensing the tendency of an electrochemical cell to change volume (such as by sensing pressure) and/or by sensing the temperature as the electrochemical cell is charged or discharged.

摘要： Methods and apparatus for diagnosing the condition of a vehicle. Some embodiments include providing an input to a vehicle suspension similar to an impact, and then measuring the response of the vehicle as it drives over an instrumented member. The motion of the instrumented member is recorded and corrected, and in some embodiments a fault index is calculated. The fault index can be displayed to a user to indicate a maintenance condition of the vehicles, such as a worn or broken component.
