A display device comprising a pixel, where the pixel includes: (a) a polar fluid that is at least one of colored and black, (b) a non-polar fluid that is at least one of transparent and translucent, (c) a first substrate, (d) a second substrate arranged relative to the first substrate to define a channel occupied by the polar fluid and the non-polar fluid, wherein at least one of the polar fluid and the non-polar fluid is visible, (e) a reflector having a plurality of features, comprising at least one of concavities and projections, that alter an angle of reflected light from a specular reflection to provide the appearance of a diffuse reflection, the display device also including a plurality of electrodes configured to cause repositioning of the polar fluid in the channel to displace at least a first portion of the non-polar fluid and a voltage source.

Controlled diffuse scattering for displays

A system and method for optimizing drill coordinates in a multi-layer printed circuit board, to correct for interlayer shift during lamination. A set of test patterns, in the form of a cross formed by two orthogonal conductor lines, are defined at each corner of each layer in the same nominal location. Under ideal conditions, the test patterns of the layers in each corner are lined up one above the other, without any offset. A counter sinking tool is used to cut a conical bore in the location of the test patterns, so that every test pattern cross is interrupted in four places, generating a four segment pattern in each layer. A high resolution camera is placed above the countersunk bore to form a single image of the exposed segment edges of all the test patterns exposed by the bore. The image is analyzed to determine the amount of shift of each layer. If all patterns are perfectly concentric, all crosses are perfectly aligned. By measuring the shift of each pattern from the nominal position, the amount of shift in each layer is determined. The process is repeated for the test patterns at each corner of the board, and the resultant layer shift data is processed to optimize the drilling pattern for the board.

Drill coordinate optimization for multi-layer printed circuit board

There is herein described an improved surface mounted component (SMC) transport mechanism which accepts a multiple number of such components from a plurality of carrier media and transports them to a desired location, for example, adjacent a printed circuit board (PCB) prior to the mounting of the SMC onto the PCB.
