20100322150 | CYCLICAL OBSTRUCTION COMMUNICATION SYSTEM - Techniques for enabling broadband data rates at mobile terminals in a beyond-line-of-sight communication system are disclosed. Forward link time-diversity transmission methods and a time-diversity transmitter based upon blockage characteristics are provided. The transmitter optionally supports selective time-diversity and can operate at Ku-band or higher frequencies. A forward link time-diversity receiver and methods for receiving a forward link time-diversity signal are also disclosed. The forward link time-diversity receiver optionally provides low-jitter or low-delay characteristics. A return link transmitter and return link transmit methods which avoid blockages are also disclosed. The return link transmitter can include a signal presence detector and blockage prediction filter. | 12-23-2010 |
20120294384 | CYCLICAL OBSTRUCTION COMMUNICATION SYSTEM - Techniques for improving data rates at mobile terminals that are subject to periodic channel interruptions in a beyond-line-of-sight communication system are disclosed, including improved encoding and decoding systems that identify blockages and modify receiver operation during blockages to reduce data errors. In certain embodiments, encoding, symbol mapping, interleaving, and use of unique periodic identifiers function to enable a series of packets that may be received in a blockage impaired channel with reduced errors. | 11-22-2012 |

20110091272 | WEIGHT SELECTING POP-PIN - A pop-pin and a method for using the pop-pin with a weight-training machine to perform mixed-weight sets of exercise are disclosed. A pop-pin having a spring loaded into an unstable equilibrium position can be inserted into a weight stack to select a weight and vertical guide bar while another conventional pin is inserted into the same weight stack and the vertical guide bar at a position above the pop-pin. A user can then operate the weight-training machine, at which point the spring on the pop-pin is dislodged from the unstable equilibrium position and presses on the weight plate into which it is inserted. When the weight stack is lowered, thus reducing the load of weight on the pop-pin, the force of the spring pressing against the weight plate ejects the pop-pin from the weight plate. At this point, the user can continue the exercise with the smaller stack. | 04-21-2011 |

20110139183 | SYSTEM AND METHOD OF PREVENTING PATTERN COLLAPSE USING LOW SURFACE TENSION FLUID - A system for processing a wafer with a low surface tension liquid includes a low surface tension liquid source including a first heat source capable of heating the low surface tension liquid to not more than 25 degrees C. less than boiling point of the low surface tension liquid, a delivery mechanism for delivering the heated low surface tension liquid to an air/liquid interface region and a second heat source directed toward the air/liquid interface region, the second heat source capable of heating the air/liquid interface region to at least 2 degrees C. greater than the boiling point of the low surface tension liquid. A method for processing a wafer with a low surface tension liquid is also described. | 06-16-2011 |

20090113656 | Apparatus for isolated bevel edge clean and method for using the same - An apparatus, system and method for cleaning a substrate edge include a bristle brush unit that cleans bevel polymers deposited on substrate edges using frictional contact in the presence of cleaning chemistry. The bristle brush unit is made up of a plurality of outwardly extending vanes and is mounted on a rotating shaft. An abrasive material is distributed throughout and within the outwardly extending vanes of the bristle brush unit to provide the frictional contact. The bristle brush unit cleans the edge of the substrate by allowing frictional contact of the plurality of abrasive particles with the edge of the substrate in the presence of fluids, such as cleaning chemistry, to cut, rip and tear the bevel polymer from the edge of the substrate. | 05-07-2009 |
20110183522 | METHOD AND APPARATUS FOR PATTERN COLLAPSE FREE WET PROCESSING OF SEMICONDUCTOR DEVICES - A method is provided for processing a wafer used in fabricating semiconductor devices. The method can comprise forming high-aspect ratio features on the wafer, which is followed by wet processing and drying. During drying, pattern collapse can occur. This pattern collapse can be repaired to allow for additional processing of the wafer. In some instance, pattern collapse can be repaired via etching where the etching breaks bonds that can have formed during pattern collapse. | 07-28-2011 |
20120199164 | Methods for Using Proximity Head With Configurable Delivery - A method for processing a substrate includes an operation of positioning a surface of a head proximate to a surface of the substrate. The surface of the head has a length and a plurality of ports that are configured in rows along the length of the head. Each row of ports can deliver a fluid to the surface of the substrate or deliver a vacuum to remove the fluid from the surface of the substrate. The method also includes an operation of controlling delivery of the fluid to one or more selected rows and delivery of the vacuum to one or more selected rows so that at least one meniscus is formed whose width depends on a desired exposure time of the meniscus to the surface of the substrate for a particular speed of relative movement between the head and the substrate. | 08-09-2012 |

20160075092 | PROCESS AND APPARATUS FOR HANDLING, INSTALLING, COMPACTING, SPLICING, AND/OR ASSEMBLING COMPOSITE STRINGERS - Methods of and systems for assembling stiffened composite structures are disclosed. Some methods include forming a stiffener assembly by compacting it within a trough formed in a trunnion. A single trunnion may accommodate two or more different types of stiffeners, thereby avoiding the need for multiple sets of tooling. In some methods, a plurality of stiffener segments may be spliced together, thereby avoiding the need to transport and handle an entire stiffener. A vacuum chuck may be utilized in some examples to transfer the stiffener assembly from the trunnion to a transfer tool. The same vacuum chuck may be transferred along with the stiffener assembly on the transfer tool and loaded onto an inner mold line layup mandrel, where the vacuum chuck may be used to compact the stiffener assembly to the inner mold line layup mandrel. | 03-17-2016 |
