    Abstract: An embodiment of the present disclosure relates to an unmanned flying robotic object that contains a wheeled mechanism that encircles its spherical exoskeleton. This feature allows the flying spherical vehicle to readily transform into a ground maneuverable vehicle. A robotic motor with differential speed capability is used to operate each wheel to provide effective ground maneuverability. There are examples provided herein of wheel configurations suitable for use with an embodiment. One is the straight- (or parallel) wheel design, and another is tilted-wheel design as are illustrated and discussed hereinafter. One embodiment of an unmanned flying robotic object taught herein is foldable.

    Abstract: Taught herein is a new contact-based optical imaging technology, en-face differential optical topography (en-face DOT), which performs real-time visualization of subsurface tissue heterogeneity within a depth up to 3 mm and over a 9.5 mm diameter FOV with a modest mm-level lateral resolution. An embodiment of the probe fits in a 12 mm port and houses at its maximum 128 cop-per-coated 750 μm fibers that form radially alternating illumination (70 fibers) and detection (58 fibers) channels. By simultaneously illuminating the 70 source channels of the laparoscopic probe that is in contact with a scattering medium and concurrently measuring the light diffusely propagated to the 58 detector channels, the presence of near-surface optical heterogeneities can be resolved in an en-face 9.5 mm field-of-view in real-time. Visualization of subsurface margin of strong attenuation contrast at a depth up to 3 mm is demonstrated at one wavelength at a frame rate of 1.3 Hz.

    Abstract: According to an embodiment, there is provided herein a method of using electrolyzed oxidizing water ice (EO ice) as a Cleaning-In-Place (CIP) method that reduces antimicrobial contamination. One embodiment is utilized in connection with beef grinders. In one embodiment, EO ice was prepared by freezing 200 mg/L free chlorine-containing EO water at 20° C. overnight. The EO ice and, optionally, EO ice/water mixture was then ground within an operating meat grinder. The EO ice treatment in combination with EO water has the potential to reduce cross-contamination and could serve as an easy to apply antimicrobial intervention to improve overall safety of ground beef.

    Abstract: This disclosure relates generally to the facile and selective mono-perfluoro and poly-fluoroarylation of Meldrum's acid to generate a versatile synthon for highly fluorinated alpha-phenyl acetic acid derivatives which provide straightforward access to fluorinated building blocks. The reaction takes place quickly and all products were isolated without the need for chromatography. An embodiment provides an alternative strategy to access alpha-arylated Meldrum's acids which avoids the need for aryl-Pb(IV) salts or diaryliodonium salts and provides access to the tertiary product which was not previously synthetically accessible. The synthetic versatility and utility of the Meldrum's acid products is demonstrated by subjecting the products to several derivatizations of the Meldrum's acid products as well as photocatalytic hydrodefluorination which provide access to difficult but valuable synthetic targets such as multifluorinated aromatics.

    Abstract: This system includes a concrete identification technology that is used in taking, testing, monitoring, and labeling concrete samples or members using custom labels called a tag. This tag comprises a series of corresponding labels, one for the outside of the form, and on for the inside of the form that becomes part of the concrete sample. These tags are physically bonded to the concrete specimen with only minimal impact on its shape and properties. In some embodiments the tags will contain a hook-and-loop or fiber type surface texture (protrusions) which is placed in the form with the protrusions facing the fresh concrete. The tag can also contain electronic circuitry to gather and track information about the concrete and the surrounding environment. This will eliminate the need to relabel the samples after demolding while also measuring a number of other parameters about the concrete and its performance.

    Abstract: There is provided herein a visible light-based speed estimation method ViLDAR. By using the received light intensity of a vehicle's LED headlight, the vehicle speed can be accurately estimated for a wide range of incidence angle. Linear LS method is used in one embodiment of a speed estimation algorithm. The impact of system parameters on speed estimation error and the performance of algorithm for different speed and estimation duration are provided. Some embodiments operate best at a certain distances where the received light intensity (power) reading can provide estimation results with high accuracy, which distances are termed a reliable region of operation. In addition to speed estimation, potential applications of ViLDAR idea are ranging detection and collision avoidance for autonomous vehicles.
