Abstract: The present disclosure provides methods and systems for the characterization of a potential microtexture region (MTR) of a sample, component, or the like. The methods may include determining a threshold width of spatial correlation coefficient and/or a threshold spatial correlation coefficient slope for an actual MTR, characterizing a potential MTR as an actual MTR or a defect, characterizing an actual MTR as an acceptable MTR or not, and/or characterizing various components with potential MTRs as defective or not. The characterization may include calculating a width of spatial correlation coefficient and/or a spatial correlation coefficient slope of the potential MTR and comparing the width of spatial correlation coefficient to a threshold width of spatial correlation coefficient and/or comparing the spatial correlation coefficient slope to a threshold spatial correlation coefficient slope for the potential MTR to be characterized as an actual MTR or a defect (crack).

Abstract: The present disclosure provides methods and systems for the characterization of a microtexture of a sample, component, or the like. The methods may include methods of determining a service life limiting region of a component, determining a treatment method for a component, and/or selecting components from a batch of components for use in production. The characterization may include calculating a microtexture level indicator from ultrasonic C-scan images for various samples, regions, components, or the like.

Abstract: A golf club grip extension and chipping training aid comprising a tubular grip extension having a central bore sized to accommodate the grip and shaft of a standard golf club such that the golf club can be inserted into the grip extension and secured. The grip extension can be removably attached with a slotted and threaded grommet that fits over the club shaft and screws into threading at the bottom of the grip extension. The club with the grip extension is a chipping training aid that allows a golfer to practice a chip shot with the grip extension pressed against the body to teach the chip shot without movement of the wrists.

Abstract: A luminaire is providing, having a substrate of a particular shape and a plurality of solid state light sources mounted thereon. The plurality has a measurable characteristic and includes an adjustable solid state light source, such that the characteristic changes in response to adjustment thereof. The luminaire also includes a sensor that detects the characteristic from outputted light, compares it to a baseline value and, based on the comparison, so adjusts the adjustable solid state light source. The luminaire also includes a reflector with a lower edge that conforms to the particular shape of the substrate, and reflects outputted light from the plurality so that it exits past the reflector's upper edge. The luminaire also includes a lightguide having an input that is surrounded by the reflector and captures a portion of the outputted light so as to provide the captured outputted light to the sensor.

Abstract: An improved cane with an internal grasping apparatus including an actuator on the cane handle and a plurality of clamps that extends from the foot or base of the cane. A cord system within the casing of the cane connects the actuator to the clamps so that when the actuator is in use, the clamps close or open to either grasp or release objects, depending on the amount of pressure applied to the actuator. Applying pressure to the actuator extends a plurality of clamps from the distal end of the cane that can be used to assist with grasping of objects. Releasing pressure to the actuator on the cane handle will retract the clamps back into the distal end of the cane to where the clamps are hidden.

Abstract: A luminaire suspension mechanism is provided. The mechanism includes two arms, two friction elements, and a compression element. Each arm includes three segments and two connection points. For each arm, a first segment attaches to a second segment at a connection point, forming a first angle, while the second segment attaches to a third segment at another connection point, forming a second angle. Each friction element is connected to a respective arm's third segment. Each arm's first segment is compressably attached to the compression element, such that a force applied to at least one of the arm-friction element pairs results in the compression element and that at least one pair exerting a suspending force that suspends a luminaire to which the luminaire suspension mechanism is attached within a cavity. The compression element may be a torsion spring, and the angles formed by the arm segments may be obtuse.
