Summary: With the increasing compactness of medical imaging devices, there is a need for research on optimizing different methods of actuation. This paper introduces an adjustable FOV piezoelectric fiber cantilever microscope and provides characterization and optimization procedures. The work demonstrates the potential to extend the usable FOV for this form of actuation and others that currently operate under ideal imaging conditions.

Summary: This paper presents an analytical model for predicting the relationship between knife-edge displacement and photointerrupter output in an optical sensor. The model accurately predicts this relationship without the need for calibration, as demonstrated by comparison with experimental data within a linear range of displacements.

Summary: The study evaluated the capability of an IOS device to detect margins of abutments prepared at different levels in relation to the gingival sulcus. Results showed that margin location is crucial for accurate impressions, and deep preparation into the sulcus is not recommended for IOS impressions.

Summary: This paper presents a technique for photomask inspection and defect analysis, which allows for accurate measurement of pattern dimensions and detection of defects in a convenient and reliable manner. The beam-shaped knife-edge interferometry (BSKEI) is used to collect and analyze interferograms created by the superposition of reference and edge-diffracted waves. BSKEI enables the measurement of various parameters and analysis of defects on the photomask.

Summary: This research focuses on evaluating the wear of delimbing knife's cutting edge using contactless methods. The study found that the blade angle and wood diameter significantly affect the amount of wear on the cutting edge, which in turn increases the cutting force. Furthermore, improving the efficiency and reducing energy consumption of the harvester machine is crucial for economic benefits.

Summary: The cutting performance of steel blades is a topic of great interest in the knife industry. This study conducted a comprehensive analysis to evaluate the cutting performance of knife blades based on a quantitative model. Factors such as the contact mechanics of the material being cut, the geometry and roughness of the blade edge, and the hardness and wear resistance of the blade steel were considered. The impact of micro-geometries of blade edges was discussed, and a geometry factor & xi; for the micro-geometry of a blade edge was introduced into the model. Experimental results showed that mechanical processing and carbides in martensitic steels had a significant effect on the cutting behavior.

Summary: Mathematical models have been developed to predict the resistance forces during inclined and sliding cutting of food materials. The study investigates the relationship between cutting angles, sliding speed, and resistance forces. The results indicate a significant reduction in resistance forces and improved cutting efficiency during inclined and sliding cutting processes.
