Abstract: An optoelectronic system includes a concentration layer, a modulation layer including an array of light modulators, an exit layer that receives the modulation layer output having a modulation layer output spatial distribution and remaps the modulation layer output spatial distribution to a modified spatial distribution. A collector layer receives the modified spatial distribution to produce a collector layer output. A detector receives the collector layer output. A processor controls the modulation layer and receives the detector output to generate an image. The collector layer can receive the modified spatial distribution at a plurality of collector layer inputs and combine the plurality of collector layer inputs at a collector layer output. Modulators can be configured to direct couple modulated light to a collector layer, without using an exit layer. Configurations with spatial light modulator modules and sub-modules are described.

Abstract: An apparatus includes a horn having a horn body including at least one horn sidewall defining a first opening that tapers down to a second opening in a direction of elongation and a port that is tubular and dimensionally uniform transverse to the direction of elongation and extends in the direction of elongation from a first port end that is in communication with the second opening to a second port end that defines an external opening. A dielectric rod includes a rod length extending between a first rod end and a second rod end with the first rod end extending through the external opening of the second port end and into the port cavity such that the first rod end is in a spaced apart relationship from the port sidewall along the light path.

Abstract: A spatial light modulator system includes a concentration layer including an array of optical concentrators, such that each concentrator concentrates a portion of an input light beam. A modulation layer includes an array of light modulators each in optical communication with one of the optical concentrators for modulating the portion of the input light beam. The light modulators are spaced apart from one another in the modulation layer to form gaps between adjacent ones of the light modulators. A coil of each light modulator can surround a Faraday element or core containing a Faraday material to control a magnetic state of a Faraday material responsive to control signals.

Abstract: Systems and methods that sense or obtain environmental conditions of a tape drive and dynamically apply voltage biases to tape head assembly elements based on the sensed/obtained environmental conditions to reduce tape stain accumulation and prolong tape head performance. Detection of different first and second sets of environmental conditions (e.g., in relation to temperatures, humidity levels, tape movement directions, etc.) may result in respective first and second voltage bias level sets being applied to respective first and second head assembly element sets. For instance, different first and second voltage bias level sets may be applied to the same head assembly elements (e.g., the first and second head assembly element sets may be the same), or the first and second voltage bias level sets may be applied to different head assembly elements (e.g., the first and second head assembly element sets may be at least partially different).

Abstract: A magneto-resistive (MR) device for reading at least one of a legacy data and a present data magnetically recorded on at least one legacy track and a least one present track, respectively, is provided. The device comprises first and second MR elements, and first, second, and third permanent magnets. The first MR read element is positioned between the first and the second permanent magnets to stabilize the first MR read element while reading the legacy data from the media. The second MR element is positioned adjacent to the second permanent magnet and configured to read the present data from the media. The third permanent magnet is positioned adjacent to the second MR element and opposite to the second permanent magnet. The second and the third permanent magnets cooperate with each other to stabilize the second MR read element while reading the present data from the media.
