Abstract: Electro-osmosis is used to create droplets in order to easily, carefully, and quickly pick-and-place millions of objects (ranging in size from millimeters to nanometers) individually or in parallel. Droplets are formed within channels that are individually controlled in order to achieve a predetermined configuration of the selected objects.

Abstract: A system and method for controlling and manipulating solidification of a molten material includes a substrate on which at least a portion of the molten material is dispensed and a first pressure adjustment system at least partially upstream of a location where the molten material is deposited on the substrate. The first pressure adjustment system imposes a first pressure at the upstream location which is different from a second pressure at a location downstream from where the molten material is dispensed.

Abstract: A method for controlling and manipulating solidification of a molten material includes generating a gradient pattern on at least a portion of a substrate and depositing the molten material on at least a portion of the substrate with the gradient pattern.

Abstract: An interactive office nameplate includes at least one of a receiver for receiving cellular wireless signals and a wireline interface for receiving wireline signals. The nameplate further includes a display for presenting information on an individual associated with the interactive office nameplate. A messaging module in the nameplate is responsive to the wireless and/or wireline signals to actuate the display to display a text message relating to the individual associated with the nameplate. A user interface further enables the preprogramming of predetermined messages within the display module or the clearing of messages presently contained within the display.

Abstract: A multiple flashpoint vaporization system rapidly sterilizes large enclosures. A plurality of vaporizers (10) inject hydrogen peroxide vapor into streams of carrier gas supplied by a generator (20). Supply lines (30) transport the mixture of carrier gas and hydrogen peroxide vapor to a plurality of regions of an enclosure (32). Monitors (52) monitor hydrogen peroxide vapor concentration or other conditions in each region of the enclosure. A control system (50) adjusts the hydrogen peroxide vapor supply rate in response to the corresponding monitored conditions.

Abstract: The invention provides a method and apparatus for minimizing heat degradation of a vapor decontaminant in a vaporizer by selectively operating a plurality of vaporizer heaters to provide a decreasing heat gradient through the vaporizer. A method and apparatus are also provided for selectively operating a plurality of preheaters, in series, for preheating a carrier gas entering a vaporizer in a flow-through decontamination system, and for maintaining a predetermined carrier gas temperature. A further method and apparatus are provided for fine-tuning chamber pressure in a high flow rate closed-loop flow-through vapor phase decontamination system.
