Abstract: A platform scale uses a method of detecting a center-of-gravity (COG) offset. A weight value of a load on a weighing platform is calculated. The weighing platform is allowed to reach a steady state. When the weight value exceeds a COG offset threshold, then a position of a load COG is calculated using a load COG position algorithm. Whether the calculated position is in a valid region of the weighing platform is determined. The weight value is displayed if the position is within the valid region; otherwise, the position of the COG is displayed. A display apparatus of the scale displays the weight value or the position of COG of the load. The platform scale alerts a user about a possible invalid weighing event by displaying an image indicative of the COG offset condition, ensuring effective and precise weighing.

Abstract: Systems and methods for structural health monitoring of adhesively bonded joints using guided waves. The method determines the quality of adhesive bonds between two materials by injecting a high-frequency (e.g., 5 MHz or higher) ultrasonic signal and measuring a characteristic of the ultrasonic waves which propagate through the adhesive, trapped and guided by the interfaces between the bonded materials and the adhesive. Prior to an inspection of an actual adhesively bonded structure, that structure is simulated using a finite element model. Also propagation of guided ultrasonic waves along the adhesive bondline is simulated to derive interface wave predicted properties. During ultrasonic inspection of the actual structure, interface wave measured properties are derived. The quality of the adhesive bondline is determined by comparing the empirical interface wave measured properties to simulated interface wave predicted properties.
