Latest Patents

One of Barker's latest patents is the "Multi-phased MEMS plate lowering and lifting system and method." This invention involves a MEMS device that features a bottom plate structure supporting a conductive electrode. A flexible conductive top plate is movably supported by a flexure and is affixed to a small peripheral portion of the top plate aligned with the electrode. The drive circuitry applies a high level of a drive voltage signal between the electrode and the top plate, producing an attracting electrostatic force sufficient to overcome the flexure and draw the top plate against the electrode. Later, the drive circuitry applies a low level of the drive voltage signal to remove the electrostatic force, allowing the flexure to peel the peripheral portion away from the electrode. Additional drive voltage signals can be applied to other electrodes to draw and sequentially remove additional peripheral portions of the top plate.

Another significant patent is related to "Testing micromirror devices." In this invention, an array of individually addressable micromirrors is characterized by sending a driving signal to a pixel group with fewer micromirrors. The response of the micromirrors in the group is measured, and the micromirror array is characterized based on the measured response.
