Abstract: A ground traversing, electrically driven drone travels along a programmed path that corresponds to pass catcher's travel path during a play, matching the pass catcher's speed and run cuts. The play is wirelessly communicated to the drone by a handheld electronic device located remote of the drone. A target is located on the drone so that a quarterback can throw a football at the target in order to refine the quarterback's timing and accuracy for the play. Sensors located remote of the drone track both the football's and quarterback's speed and travel trajectories so that such data can be collected, along with the drone's travel path, and transmitted to the computer and eventually fed into 3-D reconstruction software for analysis by the quarterback and coaching staff. The target rotates so that the target either faces in a fixed direction or constantly faces the quarterback during execution of drone's maneuvers.

Abstract: A method of measuring the value of a machine tool's performance based upon tangible results. The method specifies the core principles of defining a machine tool part setup consisting of a plane, orientation, and origin. By establishing the plane, orientation, and origin measuring programs and cutting toolpaths are recorded with precision. Machine tool results of positioning, squareness, parallelism, and circularity are revealed upon establishing the proper machine tool setup. Using the method displays the quality of a machine tool which defines its value in the marketplace.

Abstract: Embodiments of the present disclosure generally relate to silicon carbide coated base substrates, silicon carbide substrates thereof, and methods for forming silicon carbide coated base substrates. In some embodiments, a method includes introducing a first silicon-containing precursor to a process chamber at a first temperature of about 800° C. to less than 1,000° C. to form a first silicon carbide layer on a base substrate. The method includes introducing a second silicon-containing precursor, that is the same or different than the first silicon-containing precursor, to the process chamber at a second temperature of about 1,000° C. to about 1,400° C. to form a second silicon carbide layer on the first silicon carbide layer.

Abstract: The invention of a device has four threaded bolts that engage cooperatively threaded apertures in a base. These thread bolts hold the device in a temporary yet stationary position. The device has non-magnetic metal which allows test indicators to display accurate results free from any magnetic fields. The device has a precision bore of a nominal size. The radial value of the nominal size precision bore provides for mathematical calculation of the spindle centerline to work piece distance for measuring. The device has undercuts on both of its sides to aid in removing by hand. These undercuts allow the device to pivot from its stationary position for removal without damaging the planar surface. Alternatively, the device has four magnetic inserts, pocketed upwardly from the bottom surface.

Abstract: A device used in a spindle or fixture to measure tool sizes. The device has two cylindrical shapes that have precision machined surfaces. The device's face has a precise size which is the same nominal size as that of a material removing tool. The device's shaft allows for concentric and precision fastening of the device to a spindle or a fixture. The nose of the device is located on the end of the larger of the two cylindrical shapes which is visible exposed when mounted and used. The end of the device is at the end of the smaller of the two cylindrical shapes which is hidden after mounting. The device allows more accurate programming of machine tools thus providing higher quality results on machined work pieces and reducing machining cycles.

Abstract: An autonomous drone system uses an onboard command and control system for controlling operations of a drone without the need for a radio frequency controller or an external electronic device programming unit. The system uses a control unit that interacts with the drone's unmanned aerial system flight controller. The control unit is programmed via an HMI button that is resident onboard the drone. Various sequences of HMI button depressions program the drone for its missions as well as command the drone to perform the missions. A microphone can be substituted for or can augment the HMI button. Various devices, such as a speaker, lights, a visual display screen, etc., can be resident on the drone for giving a user feedback during command and programming of the drone.

The fixture body has two mountable heads that provide machine areas for inspection. The fixture body has one tooling hole that locates the assembly in a CNC machine and in a CMM. The tooling hole serves as one datum point or origin for setup. The flatness of the fixture body and the witnessed face provide repeatable setup results. The fixture body has two feet on its outer legs for fastening to any CNC machine and CMM table. The test fixture qualifies a machine tool by providing a machinable square head and a machinable round head fixed on a fixture body.
