  • Patent number: 10901289
    Abstract: A spatial light modulator having an active and a peripheral region, wherein coherent light impinges on both regions, but due to a higher spatial frequency of pixels within the peripheral region, and due to biasing the peripheral region pixels to maximize dispersion of reflected light therefrom, a majority of light reflected from the peripheral region is directed outside of a three-dimensional target window. A spatial frequency of the pixels in the active region is selected such that maximum dispersion of reflected light from the active region is incident within the three-dimensional target window. In this way, incident light that does not reflect from the active region need not be absorbed, or blocked, but instead can be reflected, but still fails to interfere with the target window.

    Abstract: Two-axis MEMS Micromirror is disclosed featuring combs drive actuation with independent drive for each of two axes of rotation and a layered hinge design providing an improved shock and vibration performance. The two-axis MEMS Micromirror is fabricated using Double SOI wafer as the primary starting material. In addition, actuation voltages are driven to an inner axis through multiple layers in one or more outer hinges, allowing for a robust and reliable micromirror that is easy to drive with multiple DC voltages, and moderately insensitive to temperature, shock and vibration. Furthermore, this novel design achieves set angles that are highly stable over time.

  • Patent number: 10386206
    Abstract: A system, method, and apparatus for active-mirroring, capacitive monitoring of furniture are provided. More particularly, the invention relates to an active mirroring system for a furniture item that monitors a first sensor type over a first frequency, while applying an inverse first frequency to at least one other sensor type coupled to the same furniture item. As such, the additional sensor types receiving the inverse sampling frequency may be dampened and/or cancelled, thereby preventing interference during monitoring of the first sensor type. In further aspects, a monitoring and mirroring cycle is provided, for sequentially monitoring and mirroring capacitive sensing mechanisms on different portions of a common furniture item.

  • Patent number: 10310355
    Abstract: A spatial light modulator having an active and a peripheral region, wherein coherent light impinges on both regions, but due to a higher spatial frequency of pixels within the peripheral region, and due to biasing the peripheral region pixels to maximize dispersion of reflected light therefrom, a majority of light reflected from the peripheral region is directed outside of a three-dimensional target window. A spatial frequency of the pixels in the active region is selected such that maximum dispersion of reflected light from the active region is incident within the three-dimensional target window. In this way, incident light that does not reflect from the active region need not be absorbed, or blocked, but instead can be reflected, but still fails to interfere with the target window.
