  • Adjustable digital microscope display
    Patent number: 10802264
    Abstract: The present invention relates in general to microscopy systems. In particular, the present invention relates to microscopes rendering digital images of samples, with the capability to digitally control the focus of the microscope system, and the software used to control the operation of the digital microscope system. Further, the present invention relates to a microscope structure that allows for compact and multi-functional use of a microscope, providing for light shielding and control with samples that require specific light wavelength characteristics, such as fluorescence, for detection and imaging.
    Type: Grant

  • Universal mechanical tester for measuring friction and wear characteristics of materials
    Patent number: 10132733
    Abstract: Proposed is a universal mechanical tester for measuring friction and wear characteristics of materials. The tester allows performing multiple test protocols with a single machine. The tester consists of a frame that supports a carriage moveable in a vertical direction, a force sensor assembly attached to the carriage, a positioning stage with a slide and a platform, and a plurality of modular sample stages interchangeably installable on the platform for executing linear and rotary motions of the lower sample relative to the upper sample in various directions and planes. The tester is provided with a set of electronic identification devices for identifying a modular sample stage installed on the platform and the force sensor assembly attached to the carriage.
