Abstract: Profilometers for industrial metrology and other applications are described. A line is projected on a surface to be profiled. The line is scanned to build a three dimensional point cloud allowing the three-dimensional (3D) profile of the surface to be determined. In some embodiments, the line is projected by a laser system. In other embodiments, the line is projected by a digital micromirror device (DMD). In still further embodiments, multiple lines, or other patterns are projected.

Abstract: A photodetector assembly for ultraviolet and far-ultraviolet detection includes an anode, a microchannel plate with an array of multichannel walls, and a photocathode layer disposed on the microchannel plate. Additionally, the photocathode may include nanowires deposited on a top surface of the array of multichannel walls.

Abstract: A system and apparatus for navigating and tracking a robotic platform includes a non-contact velocity sensor module set positioned on the robotic platform for measuring a velocity of the robotic platform relative to a target surface. The non-contact velocity sensor module set may include a coherent light source that is emitted towards the target surface and reflected back to the coherent light source. Measuring the change in intensity of the reflected coherent light source may be used to determine the velocity of the robotic platform based on the its relationship with the principles of a Doppler frequency shift. A communication unit may also be utilized to transmit data collected from the non-contact velocity sensor set to a computer for data processing. A computer is then provided on the robotic platform to process data collected from the non-contact velocity sensor set. A user may then monitor the determined trajectory path of the robotic platform and transmit navigation instructions to the robotic platform based on the received trajectory path data.

Abstract: Embodiments of the disclosed lithium ion rechargeable battery include an anode, a cathode, and a separator including an electrolyte to prevent physical contact between the anode and the cathode, while also providing medium for transporting the lithium ions. In some embodiments, the anode may include a microporous scaffold structure that includes a silicon crystal covered in a thin polycrystalline silicon cover. Additionally, the various embodiments described herein further describe increasing the surface area of the microporous scaffold structure so as to provide a more efficient charge flow between the anode and the cathode. In some embodiment, the two or more microporous scaffold structures are stacked on top of one another so that there is an increase in contact area and reduced contact resistance, thus further increasing the charge capacity of the disclosed lithium ion rechargeable battery.
