Abstract: Devices, systems, and techniques are provided for improved OVJP deposition using a shutter disposed within the OVJP print head, between the print head inlet and the nozzle outlets. An OVJP print head as disclosed includes an inlet for organic material entrained in a carrier gas, a micronozzle array outlet, and a shutter disposed in the gas flow path between the inlet and the micronozzle array outlet. The shutter allows for rapid cutoff of carrier gas flow through the print head with extremely low latency.

Abstract: Embodiments of the disclosed subject matter provide an organic vapor jet printing (OVJP) system having a printhead that include a fluidic shutter comprising a plurality of microchannels that are in fluidic communication with one another, and a micronozzle array connected to the fluidic shutter. The plurality of microchannels include a first microchannel to receive the carrier-organic mixture, a second microchannel to receive a blocking gas, a third microchannel connected to the micronozzle array, and a fourth microchannel connected to an exhaust line. The carrier-organic mixture may be deposited on a substrate when the apparatus operates in a first operating mode, and the blocking gas may direct evaporated organic material of the carrier-organic mix to the exhaust line when the apparatus operates in a second operating mode.

Abstract: A method of displaying building system controller data includes receiving a user login associated with predefined user access privileges and receiving a building system controller selection, requesting a listing of building system controller applications and activities from a building system controller associated with the building system controller selection, and generating a display of available building system controller applications and allowable activities based on the user access privileges and based on the listing.

Abstract: A method comprises grouping a plurality of building system controllers into at least one control system group, the at least one control system group corresponding to at least one connected group of building system controllers. The method also comprises grouping the at least one control system group into at least one site group, the at least one site group corresponding to a physical location of the at least one control system group. The method also comprises selecting a group from the at least one site group and the at least one control system group, and performing an activity on each controller within the selected group.

Abstract: A Moiré interferometric-based shear-stress sensor includes a substrate support. The substrate includes a first optical grating disposed in or on the substrate, the first grating having a plurality of features defining a first spatial period. A floating element having a second optical grating is disposed in or on the floating element. The second grating has a plurality of features defining a second spatial period. The floating element is suspended over the first grating and flexibly connected to the substrate with compliant springs, wherein the respective gratings are in an optical path with one another. Upon irradiation, the sensor forms a Moiré fringe pattern which relates to a shear-stress induced translation of the floating element.

Abstract: A multi-resonator-based system responsive to acoustic waves includes at least two resonators, each including a bottom plate, side walls secured to the bottom plate, and a top plate disposed on top of the side walls. The top plate includes an orifice so that a portion of an incident acoustical wave compresses gas in the resonators. The bottom plate or the side walls include at least one compliant portion. A reciprocal electromechanical transducer coupled to the compliant portion of each of the resonators forms a first and second transducer/compliant composite. An electrical network is disposed between the reciprocal electromechanical transducer of the first and second resonator.
