Abstract: A method for repositioning an abrasive disc within a repositionable abrasive disc mounting assembly is presented. The method includes mounting the abrasive disc to a repositionable abrasive disc mounting assembly in a first position. The mounting disc assembly includes the abrasive disc coupled to the back-up pad assembly such that the abrasive disc is in contact with a pressure feature of the back-up pad assembly, a drive shaft of a grinding tool, and a fastener that maintains the position of the abrasive disc and the back-up pad coupled to the drive shaft. The method also includes conducting an abrasive operation by activating the grinding tool. The method also includes re-positioning the abrasive disc, with respect to the repositionable abrasive disc mounting assembly, in a second position. The first position includes the abrasive disc in a first position relative to the pressure feature. The second position includes the abrasive disc in a second position relative to the pressure feature assembly.

Abstract: Medical adhesive articles include a layer of adhesive and a modified substrate layer where the layer has a plurality of cuts arrayed in a pattern that may be random or the pattern can be arrayed along at least one axis. The cuts are gaps, but the gaps are not visible to the naked eye when the adhesive article is in an unstressed state, and at least some of the cuts become gaps that are visible to the naked eye and form apertures when the adhesive article is in a stressed state. The adhesive articles can be used to adhere a medical device to skin.

Abstract: Medical dressings including stiffening systems fixedly attached to backing layers are described herein along with methods of using the medical dressings. The stiffening system is fixedly secured to the backing to limit flexing and stretching of the backing layer. Typically, the medical dressing and stiffening system is applied over a medical device that is secured to skin. The stiffening system covers some of the medical device and also extends beyond the medical device. The stiffening system stabilizes the medical device over the skin.

Abstract: The present disclosure relates to crush resistant packaging materials and/or constructions and to methods of making and using them. Many embodiments provide crush resistance in addition to customizability.

Abstract: Various apparatuses are disclosed including those that have curvature arresting properties. According to one example, the apparatus can optionally include a flexible first film, a second film and a first plurality of features. The first plurality of features can be disposed between the first film and the second film At least some of the first plurality of features are spaced apart from one another by a gap when the first film is not subject to an applied bending force or is subject to the applied bending force below a predetermined magnitude in one or both of the transverse direction and the longitudinal direction, and at least some of the first plurality of features contact one another to arrest a curvature of the first film when the applied bending force is at or above the predetermined magnitude.

Abstract: An article comprises a cap and a cover. The cap comprises an opening to an interior cavity, and has an inner surface defining the interior cavity and an outer surface. The cover is disposed within the interior cavity of the cap near the opening. The cover comprises a base having an inner surface facing the cap opening and an opposite outer surface. A sidewall of the cover extends from a perimeter of the base toward the cap opening. The sidewall has an outer surface facing the inner surface of the cap and an opposite inner surface. Micro features are provided on at least the inner surface of the sidewall. The cover is displaceable into the interior cavity of the cap.

Abstract: The present disclosure describes light delivery and distribution components of a ducted lighting system having a cross-section that includes at least one curved portion and a light source. The delivery and distribution system (that is, light duct and light duct extractor) can function effectively with any light source that is capable of delivering light which is substantially collimated about the longitudinal axis of the light duct, and which is also preferably substantially uniform over the inlet of the light duct.

Abstract: The disclosure generally relates to concentrating daylight collectors and in particular to a light concentrator alignment system that can detect and correct for misalignment of the solar concentrator. The present disclosure generally relates to concentrating daylight collectors that can be used for illuminating interior spaces of a building with sunlight, and in particular to a light concentrator alignment system that can detect and correct for misalignment of the solar concentrator.

Abstract: The present disclosure describes light delivery and distribution components of a ducted lighting system having a cross-section that includes planar duct portions, and a light source. The delivery and distribution system (that is, light duct and light duct extractor) can function effectively with any light source that is capable of delivering light which is substantially collimated about the longitudinal axis of the light duct, and which is also preferably substantially uniform over the inlet of the light duct.

Abstract: The disclosure generally relates to highly efficient light duct light splitters that are capable of splitting the light propagating within a light duct into two different ducts, with nearly 100 percent efficiency. In particular, the described light splitters are configured in a “Tee” shape with a reflective splitter element.

Abstract: The disclosure generally relates to highly efficient light duct light extractors that are capable of extracting a portion of the light propagating within a light duct with nearly 100 percent efficiency. In particular, the described light extractors are configured in a “Tee” shape with a reflective diverter element.

Abstract: The present disclosure provides a system and method for controlling spot lights, such as theater or display lights, which incorporates a handheld remote control that uses intuitive motions for selecting, positioning, dimming and other lighting setup functions. The present disclosure describes a spotlight control device, a lighting system including the spotlight control device, and a method for spotlight control. The spotlight control device incorporates a first light source that emits a first control beam that activates a desired spotlight. The activated spotlight can provide feedback to indicate that it has been activated. A second light source from the control device emits a second control beam that is used to direct the activated spotlight to an illumination region.

Abstract: The present disclosure describes a compact spotlight that can change the area which it illuminates. The spotlight incorporates a wide angle light source, a catadioptric lens, and a bearing system for moving the catadioptric lens, the light source, or both. Movement of the light source relative to the catadioptric lens along the optical axis can change the beam diameter of the spotlight, while providing an acceptable illumination pattern.
