20110046900 | IMPULSE ANALYSIS FOR FLOW SENSOR-BASED FLUID CONTROL SYSTEM - A fluid flow control system using flow rate changes to extract additional information from an in-line flow sensor. The system provides the ability to determine a position of a movable flow sensor element of a flow sensor by illuminating a photosensitive pixel array with a light source to create a first set of pixel intensity values, introducing an abrupt change to the fluid driving pressure, illuminating the photosensitive pixel array with a light source to create a second set of pixel intensity values, and calculating the difference between the first and second sets of pixel intensity values as a function of pixel position. | 02-24-2011 |

20110307902 | ASSIGNING TASKS IN A DISTRIBUTED SYSTEM - A method and apparatus are provided for assigning tasks in a distributed system. The method comprises indicating to one or more remote systems in the distributed system that a task is available for processing based on a list identifying the one or more remote systems. The method further comprises receiving at least one response from the one or more remote systems capable of performing the task based on the indication. The method comprises allowing at least one of the remote systems to perform the task based on the at least one received response. | 12-15-2011 |

20110285794 | FLUID EJECTOR STRUCTURE - In one embodiment, a fluid ejector structure includes: a chamber for containing a fluid; a flexible membrane forming one wall of the chamber; a plurality of piezoelectric elements; a backing operatively connected to the piezoelectric elements such that an expansion and/or contraction of a piezoelectric element causes the piezoelectric element to bend; a rigid plate overlaying a center portion of the membrane; a post coupling the piezoelectric elements to the plate through the backing such that a movement of each piezoelectric element toward the chamber is transmitted to the plate through the post. The plate is configured to transmit movement of the post to the membrane in a rigid, or substantially rigid, piston-like manner. | 11-24-2011 |

20100328758 | Electrophoretic Display Device - A multi-stable electrophoretic display device has a plurality of pixels and comprises a first substrate and a second substrate. The substrates are spaced apart from each other and enclose a layer of an electrophoretic medium comprising a liquid crystal material having finely divided pigment particles dispersed therein. The device further comprises electrodes for formation of a pixel area outline and applying an electric field across at least some of the electrophoretic medium in the pixel area. The electrodes occupy substantially less than the entire field of view of the display pixels and can be used to effect switching between a first optical state in which most incident light on a pixel does not impinge on a pigment particle, and a second optical state in which most incident light on a pixel impinges on pigment particles. | 12-30-2010 |
20110024936 | Systems to Produce an Object Through Solid Freeform Fabrication - A method for producing an object formed through solid freeform fabrication includes dispensing a binder on successive layers of build material with a single first dispensing member; and coloring the successive layers with at least one second dispensing member, where the second dispensing member over-dispenses the first dispensing member. Another method for producing an object through solid freeform fabrication includes dispensing a first binder on successive layers of build material with a single first dispensing member; and dispensing a second binder on the successive layers of build material with at least one second dispensing member, where the second dispensing member over-dispenses the first dispensing member. | 02-03-2011 |
