A system and method for providing a dimming factor of N using a laser display device having plural colored laser diodes each generating a colored laser beam according to control parameters. At least one of the control parameters of at least one of the laser diodes is varied, at least one of the control parameters being operative to reduce intensity of at least one of the colored laser beams. Varying may comprise providing a dimming factor of m


A system for projecting 2D images, providing a computerized representation of a first, dense, grid of spatial 3D coordinates which respectively correspond to a set of time-points evenly distributed along a time-dimension with constant time-discretization; deriving a dense 2D representation of an image, whose coordinate pairs respectively correspond to said set of time-points; d. Defining a sparse 2D grid of second coordinate pairs, spaced such that distances between any two adjacent coordinate pairs along a row of said sparse 2D grid are constant; and finding, coordinate pairs closest to the second sparser grid to yield a third grid, and a laser controller to control the laser to project a digitally represented image, from said distance, timed to project pixels whose locations respectively correspond to the subset of uniformly distanced positions forming said third grid, thereby to prevent image distortion despite non-uniformity of micro-mirrors angular velocity.

A new raster-scanning chipset which provides enhanced projection performance is presented. The design is novel in that it combines electrostatic and electromagnetic actuation methods, along with a unique feedback-control scheme to produce SVGA and WVGA projected images. A micromirror, the actuators, and drive electronics are integrated into a small, power-efficient system, a scanning chipset, to increase its reliability and manufacturability. © Copyright 2010 Society for Information Display.

Three-dimensional solenoids have been developed and demonstrated for the first time in stacking of through-silicon via chips. High-density microcoils (∼20μ m width, ∼10 μm space, and ∼ 90-μ m depth with 24 turns) were completely filled with Cu. Eight high-density microcoil chips were stacked using a conductive adhesive. The inductance of the eight stacked high-density microcoil chips is measured to be ∼30μH at 0.9 MHz, and the maximum magnetic field reaches to ∼ 0.67 mT, as characterized by a magnetic field detector ∼2 mm above the cavity center of the coils. The eight stacked high-density microcoil chips achieved 66-h operation under continuous current (∼0.2 A) stress testing without failure. Two microcoil chips stacked using solder also completed 1000 thermal cycles (40 °C to 125 °C) successfully with merely ∼3.7% resistance change. © 2012 IEEE.
