  • Patent number: 9759909
    Abstract: Scanning platforms for use in scanning laser devices are described herein. These scanning platforms are particularly applicable to scanning laser devices that use microelectromechanical system (MEMS) structures to facilitate mirror motion. The scanning platforms include a centrally located stationary mount portion and a movable portion that surrounds the stationary portion. The movable portion is configured to be coupled to a mirror and to facilitate motion of that mirror. Such a scanning platform can facilitate reduced size in scanning mirror assembly, and thus can facilitate a more compact scanning laser device.

  • Patent number: 9753279
    Abstract: An electrostatically actuated oscillating structure includes a first stator subregion, a second stator subregion, a first rotor subregion and a second rotor subregion. Torsional elastic elements mounted to the first and second rotor subregions define an axis of rotation. A mobile element is coupled to the torsional elastic elements. The stator subregions are electrostatically coupled to respective regions of actuation on the mobile element. The stator subregions exhibit an element of structural asymmetry such that the electrostatic coupling surface between the first stator subregion and the first actuation region differs from the electrostatic coupling surface between the second stator subregion and the second actuation region.

  • Patent number: 9746590
    Abstract: A printed retroreflective film has a planar surface on a front side and a plurality of retroreflective elements on a back side. A halftone printed ink layer is deposited on the planar surface formed from uniformly spaced, discrete dots of deposited ink. The areas between the dots provide light-transmissive openings that receive incident light and transmit retroreflected light. The aggregate area of the dots forming the half-tone pattern preferably covers between about 60% and 90% of the area of the half-tone pattern. The use of such a halftone pattern of ink increases the reflectivity of the printed retroreflective sheeting by reducing the amount of light absorbed by the ink, and by reducing the amount of light scattered by the layer of ink. The use of such a halftone pattern of ink further obviates the need for an anti-light scattering topcoat or film over the front surface of the retroreflective sheet.

  • Patent number: 9703023
    Abstract: Cube corner articles such as retroreflective sheeting utilize multiple cube corner arrays in a tiled configuration, each tile containing one array of canted cube corner elements. The tiles may be long and narrow, and the array in each of at least two or three adjacent tiles, or even in every tile, may include at least one lengthwise groove that is parallel to an edge of the tile and parallel to a fixed in-plane axis. Each tile may have a width that is narrow (e.g. 0.2 to 5 mm), and equal to an integer multiple of a lengthwise groove pitch to avoid or reduce ineffective fragmented cube corners along the tile edge. Each array may have a plane of cant and a primary plane of entrance angularity, and the primary planes of entrance angularity for the multiple tiles may be more evenly distributed in azimuthal angle than the planes of cant.
