Abstract: The disclosed technology relates to methods of patterning elongated structures. In one aspect, a method of forming pillars includes providing a substrate and providing a plurality of beads on a surface of the substrate. Regions of the surface without a directly overlying bead are exposed. The method additionally includes selectively etching the exposed regions of the substrate between the beads such that a plurality of pillars is formed under areas masked by the beads. Selectively etching completely removes at least some of the beads. The pillars that are not covered by beads are etched, thereby leaving some pillars taller than others, with the pillar height pending on the amount of time a pillar was left exposed to etchant by a removed bead.

Abstract: This disclosure provides systems, methods, and apparatus for an electromechanical systems (EMS) device with one or more protrusions connected to a surface of the EMS device. In one aspect, the EMS device includes a substrate, a stationary electrode over the substrate, and a movable electrode over the stationary electrode. The movable electrode is configured to move to three or more positions across a gap by electrostatic actuation between the movable electrode and the stationary electrode. When the protrusions contact any surface of the EMS device at one of the positions across the gap, the protrusions change the stiffness of the EMS device. At least one of the surfaces in contact with the one or more protrusions is non-rigid. In some implementations, the protrusions have a height greater than about 20 nm.

Abstract: An optical touch sensor may include traces of photoconductive material formed on a substantially transparent substrate. Each photoconductive trace may be capable of responding to an incident light intensity increase on a portion of the photoconductive trace by increasing the number of charged carriers, thereby raising the electrical conductivity of that portion of the photoconductive trace. An incident light intensity decrease on a portion of the photoconductive trace will lower the electrical conductivity of that portion of the photoconductive trace. The corresponding changes in voltage may be measured by circuits that include conductive traces formed substantially perpendicular to, and configured for electrical connection with, the traces of photoconductive material. A diode (such as a Schottky diode) may be formed at the electrical connections between the conductive traces and the photoconductive traces.

Abstract: Methods and systems may facilitate access to media. A mobile computing device may manage media associated with links by evaluating factors that may affect battery life. The mobile computing device may obtain information about the media associated with the links, such as metadata indicating file characteristics, identifying information, and analytics. The information may be included in the media or obtained from a server. The mobile computing device may evaluate factors that affect the device's ability to receive and render the media. Such factors may include the battery charge state, signal strength, connectivity, or media characteristics (e.g., size, complexity, etc.). The mobile computing device may prioritize the links associated with the media based on the evaluation of the factors, such as by sorting the links by rank. The mobile computing device may also hide links, display warnings/indicators, display links in particular manners or formats, and automatically download the media.
