20150251917 | METHOD OF PATTERNING PILLARS - 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. | 09-10-2015 |
20150277097 | FLEXIBLE EMS DEVICE USING ORGANIC MATERIALS - This disclosure provides apparatus, systems and methods for an electromechanical systems (EMS) device made of organic materials. In one aspect, the EMS device includes a stationary electrode over a substrate and a movable electrode over the stationary electrode, where the movable electrode is configured to move across a gap between the movable electrode and the stationary electrode by electrostatic actuation. One or more layers between the movable electrode and the stationary electrode may be made of polymer material. One or more layers in the EMS device may include an optical layer made of polymer material and configured to attenuate energy of light corresponding to one or more wavelength ranges. In some implementations, the optical layer may include a plurality of absorber particles in a host material that is electrically insulating. | 10-01-2015 |
20150277098 | EMS DEVICE HAVING A NON-ELECTRICALLY ACTIVE ABSORBER - This disclosure provides apparatus, systems and methods for an electromechanical systems (EMS) device having a non-electrically active absorber. In one aspect, the EMS device includes a stationary electrode over a substrate, a dielectric layer over the stationary electrode, an absorber over the dielectric layer, and a movable electrode over the absorber. The movable electrode is configured to move to a plurality of positions between the absorber and the movable electrode to define a plurality of gap heights. Furthermore, the absorber includes a non-electrically active material. In some implementations, the absorber can include an optical layer having a plurality of particles in an electrically insulating material. | 10-01-2015 |
20150277099 | EMS DEVICE HAVING FLEXIBLE SUPPORT POSTS - This disclosure provides apparatus, systems and methods for an electromechanical systems (EMS) device having one or more flexible support posts. In one aspect, the EMS device includes a substrate, a stationary electrode over the substrate, one or more flexible support posts over the substrate, and a movable electrode over the stationary electrode and supported by the one or more flexible support posts. The movable electrode is configured to move across a gap between the movable electrode and the stationary electrode upon electrostatic actuation, where the one or more flexible support posts include a first organic material and can be configured to compress to permit the movable electrode to move across the gap. | 10-01-2015 |

20090222804 | EMBEDDED FIRMWARE UPDATING SYSTEM AND METHOD - A system and method is described for updating firmware in a welding or plasma cutting system. A removable memory device containing updated firmware code and a set of execution instructions is interfaced with one or more component boards. The execution instructions are executed on a processor of the welding or plasma cutting system to load the updated firmware code stored on the removable memory device into memory of the welding or plasma cutting system via an interface, generally overwriting the old firmware code. | 09-03-2009 |
20090277893 | WELDING POWER SUPPLY WITH SCALED OUTPUT VOLTAGE - A method and system for adjusting the output voltage applied to a wire electrode during an automatic parameter selection mode in which the rate of advancement and output voltage is automatically determined. A control circuit determines appropriate power parameters in response to at least one configuration parameter. The control circuit generates a power command accordingly based on an expected, or nominal, input voltage. A sensor connected to the control circuit monitors the actual input voltage. If the actual input voltage is outside of an acceptable range, the control circuit scales the generated power command with a scaling factor calculated based on the actual input voltage. | 11-12-2009 |
20110220629 | WELDING WIRE FEEDING SYSTEMS AND METHODS - Welding wire feed systems include a wire feeder including a push motor and a welding torch assembly including a pull motor are provided. The push motor is adapted to establish a wire feed from a wire spool, and a first controller is adapted to receive a commanded speed level and to control operation of the push motor to operate at the commanded speed level. The pull motor is adapted to cooperate with the push motor to establish a desired wire feed rate from the wire spool to the welding torch assembly. A second controller is adapted to receive an operational speed level of the push motor from the first controller and to control operation of the pull motor to operate at the received operational speed of the push motor. | 09-15-2011 |
20110220630 | WELDING WIRE FEEDER WITH MULTIMOTOR STANDARD - A welding wire feeder having a multiple motor drive standard is provided.
