    摘要： A vertical-cavity surface-emitting laser that generates light having a fixed direction of polarization. The laser has a plane light-generating region sandwiched between a first conductive mirror region and a second conductive mirror region. The first conductive mirror region has an opposite conductivity mode from the second conductive mirror region. The first conductive mirror region has a remote surface substantially parallel to the light-generating region and an electrode formed on the remote surface. The electrode bounds a light emission port from which the light is emitted in a direction defining an axis. A reduced-conductivity region is formed in the first conductive mirror region surrounding the axis and extending from the remote surface towards the light-emitting region to define a core region in the first conductive mirror region. The light emission port and/or the core region has first and second dimensions in orthogonal directions in a plane parallel to the light-generating region. The first dimension is greater than the second dimension to set the direction of polarization of the light to the direction of the first dimension.

    摘要： Method and apparatus for determining the distance a sheet of paper, or other reflective or transmissive substrate material with a suitable, approximately planar surface, has moved in a given direction. The substrate is illuminated by reflection or transmission of light at non-normal incidence, and a linear array of N uniformly spaced light sensors is provide to receive and sense light issuing from the illuminated substrate. This produces a first or reference array of light signal strengths s.sub.1 (k) (k=1,2, . . . , N). The substrate is then moved in the given direction, and a second array of signal strengths s.sub.2 (k) (k=1, 2, . . . , N) is produced. A cross-correlation function C(K), formed from consecutive portions of the first and second light signal strength arrays, is then examined to determine the distance the substrate has moved in the given direction. A maximum in the cross-correlation function C(K) at K=K.sub.0 corresponds to displacement of the substrate in the given direction by a distance approximately equal to (MF)(K.sub.0 -i)d, where i is selected positive integer determined by the initial position of the substrate, the distance d is determined from the known spacing of the light sensors, and MF is the system optical magnification factor. The cross-correlation function can be computed with uniform or non-uniform weights in the sum. This one-dimensional approach is extended to determining the vector of two-dimensional movement of the substrate, including translation, rotation and scaling, in a two-dimensional plane.

The measurement device includes a fluid cell, a pair of electrodes, a voltage switch, and a measurement unit. The fluid cell is on an inclined plane to receive the fluid. The pair of electrodes are connected to the fluid cell. The pair of electrodes are spaced apart from one another to receive the fluid therebetween and positioned parallel to one another to pass an electrical current therethrough. The power unit provides a high voltage power supply to one electrode of the pair of electrodes. The measurement unit measures the electrical current that passes between the pair of electrodes through the fluid.

    摘要： An electrode array with embedded thin-film transistors is fabricated with a self-aligned imprint lithography process. In an embodiment the electrode array is built over a flexible, conductive, substrate, in an alternative embodiment the electrode array is built on a curved substrate. In an embodiment, the electrode array is incorporated into a printer, and is coated with a passivation layer having openings for each electrode of the array. The printer develops an image by selectively charging electrodes of the array, the openings of each electrode being exposed to an electrophoretic ink. Charged particles of the electrophoretic ink migrate to charged electrodes, thereby forming an image that is transferred to a printing substrate such as paper.
