Abstract: A system for authenticating an object includes at least one laser configured for interacting with a tag, the tag comprising structural changes to the object, the structural changes being responsive to terahertz electromagnetic waves. The system may also include a processor configured to (i) receive electromagnetic wave data resulting from interaction of the terahertz electromagnetic waves with the structural changes, (ii) compare the electromagnetic wave data to a reference standard, (iii) determine that the object is authentic in response to the electromagnetic wave data meeting the reference standard, and (iv) determine that the object is not authentic in response to the electromagnetic wave data not meeting the reference standard. A system for reading a tag of an object is further provided.

Abstract: A system and method for generating a three-dimensional image of a sample. The system comprises a platform configured to support the sample, a laser source configured to output a laser beam to remove material from the sample, a microscope imaging system, and a controller communicatively coupled to the laser source and the microscope imaging system. The controller is configured to (a) acquire height data of a surface of the sample with the microscope imaging system, (b) generate a mask based on the height data of the surface of the sample, the mask providing a laser cutting pattern for the sample, (c) acquire an image and a height map of the surface of the sample with the microscope imaging system, (d) activate the laser source to generate a laser beam to delayer the sample based on the mask, and repeat steps (a)-(d) to generate a three-dimensional image of the sample.

Abstract: Systems and methods for detecting a material composition of a specimen and for cross-sectioning of the specimen. The system includes an imaging system, a femtosecond laser source, and optionally, a synchronized CO2 injection system. The imaging system is configured to capture image data of a surface of the specimen that has been etched by the laser. A machine learning model is applied to determine a predicted material composition of the specimen based at least in part on the image data. The machine learning model is trained to receive as input the image data and/or one or more quantified surface texture parameters determined from the image data and to produce as output an indication of a predicted material composition. A laser-based milling system is configured to use these material composition detection mechanisms to automatically determine when the laser system has milled through a first layer of a specimen and reached a second layer, and to adjust the operation of the milling system in response.

Abstract: A resealable shaving solid applicator comprising an upper section, a support for a shaving solid, a shaving solid, and a lower section is provided. The support for a shaving solid may comprise one or more resilient tabs for engaging a shaving solid to form a mounted shaving solid. Methods for introducing a shaving solid into a resealable shaving solid frame to form a resealable shaving solid applicator are also provided herein.

Abstract: A water-activable shaving composition is provided. The solid composition has a melting point between 41° C. +(0.2% +2.5° C.) and 46° C.+(0.2%+2.5° C.) when saturated with water. It is a propylene glycol based composition containing less than 15% by wt. of a fatty acid salt. The composition may also include water, glycerine, steareth 20, sodium stearate palmstar, polyethylene glycol powder, cocamide monoethanolamine (MEA), tea tree oil and optionally vegetable oil. The propylene glycol at least partly serves to both hydrate hairs prior to shaving as well as moisturize the skin.
