Patent number: 11886057Abstract: 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.Type: GrantFiled: February 3, 2023Date of Patent: January 30, 2024Assignee: Syght, Inc.Inventors: Charles C.

Patent number: 7986485Abstract: A servo writing method is provided for use with unoriented magnetic tape media. A biasing zone is formed, such as between a pair of permanent block or disk magnets, with a strong DC magnetic field that is substantially free of perpendicular components. The method includes feeding the tape through the magnetic biasing zone to form a longitudinal magnetic bias in the magnetic layer of the tape media. The method includes using a write head to write a servo pattern on the tape media after the forming of the longitudinal magnetic bias in the tape media, and the servo pattern produces an output that is substantially symmetric with high amplitudes. In one embodiment, the biasing zone is formed or defined as the gap between first and second magnetic assemblies oriented with a single direction of magnetization, such as in the same direction as the tape travel through the biasing zone.Type: GrantFiled: March 31, 2009Date of Patent: July 26, 2011Assignee: Oracle America, Inc.Inventors: Kevin D.
