    Abstract: An electronic device includes a display and a processor coupled to the display. The display includes a plurality of zones distributed over a viewable display area. The processor is configured to obtain source data for the image to be displayed in the viewable area of the display, analyze the source data in selected zones of the plurality of zones to determine at least one characteristic of the image in each selected zone, and adjust, separately in each zone of the plurality of zones, at least one type of subpixel in the subpixel matrix based on determined characteristics of the image in the selected, analyzed zones.

    Abstract: A coated abrasive disc includes an abrasive layer disposed on a major surface of a disc backing. The abrasive layer comprises triangular abrasive platelets secured to a major surface of the disc backing by at least one binder material. The triangular abrasive platelets are outwardly disposed from the major surface at contiguous intersections of horizontal and vertical lines of a rectangular grid pattern, wherein the intersections of the rectangular grid pattern have an areal density defined by C/(LT) where C is a unitless coverage factor having a value between 0.1 and 0.4, L is the average major triangular abrasive platelet side length and T is the average triangular abrasive platelet thickness. At least 70 percent of the intersections have a triangular abrasive platelet disposed thereat. Each one of the triangular abrasive platelets has respective top and bottom surfaces connected to each other, and separated by, three sidewalls, and, on a respective basis, one sidewall facing the disc backing of at least 90 percent of the triangular abrasive platelets has a Z-axis rotational orientation within 10 degrees of the vertical lines. Methods of making and using the coated abrasive discs are also disclosed.

    Abstract: A coated abrasive disc includes a disc backing having an outer circumference. An abrasive layer is disposed on the disc backing. The abrasive layer comprises triangular abrasive platelets secured to a major surface of the disc backing by at least one binder material. The triangular abrasive platelets are outwardly disposed at regularly-spaced points along a spiral pattern extending outwardly toward the outer circumference. Each triangular abrasive platelet has respective top and bottom surfaces connected to each other, and separated by, three sidewalls. On a respective basis, one sidewall of at least 90 percent of the triangular abrasive platelets is disposed facing and proximate to the disc backing, and at least 70 percent of the triangular abrasive platelets are disposed in a recurring sequential orientation having an oscillating Z-axis rotational orientation of the first respective sidewall relative to the tangents to the spiral pattern at regularly-spaced points. Methods of making and using the coated abrasive disc are also disclosed.

    IPC: B24D11/00

    Abstract: A coated abrasive belt (100) includes a belt backing (110) and an abrasive layer disposed thereon. The abrasive layer comprises abrasive elements (160) secured to at least a portion of a major surface of the belt backing (110) by at least one binder material. The abrasive elements are disposed at contiguous intersections of horizontal (192) and vertical lines (194) of a rectangular grid pattern. Each abrasive element has at least two triangular abrasive platelets (130), each having respective top and bottom surfaces connected to each other, and separated by, three sidewalls. On a respective basis, one sidewall of the triangular abrasive platelets is disposed facing and proximate to the belt backing A first portion of the abrasive elements is arranged in alternating first rows (16) wherein the triangular abrasive platelets are disposed lengthwise aligned with the vertical lines (194). A second portion of the abrasive elements is arranged in alternating second rows (168) wherein the triangular abrasive platelets (130) are disposed lengthwise aligned with the horizontal lines (194). The first and second rows repeatedly alternate along the vertical lines. Methods of making and using the coated abrasive belt are also disclosed.
