| 20090187292 | INTEGRATED PITCH, ROLL, AND YAW INCEPTOR - A method and apparatus for a control system for an aircraft. The control system comprises a grip, a set of feedback components connected to the grip, and a set of sensors. The set of feedback components transmit a restoring force opposite to a movement of the grip. The set of sensors are capable of detecting pitch input, roll input, and yaw input in response to the movement of the grip. | 07-23-2009 |

| 20080269420 | Shape Memory Epoxy Copolymer - The shape memory polymers disclosed are a reaction product of at least one reagent containing two active amino-hydrogen or two active phenolic-hydrogen with at least one multifunctional cross linking reagent which contains at least three or more active amino- or phenolic-hydrogen or is a reagent containing at least three glycidyl ether moieties which is then further mixed with at least one diglycidyl ether reagent whereupon the resulting mixture is cured and has a glass transition temperature higher than 00C. This reaction creates crosslinking between the monomers and polymers such that during polymerization they form a crosslinked thermoset network. | 10-30-2008 |
| 20090258575 | Chemical Mechanical Polishing Pad and Methods of Making and Using Same - Shape memory chemical mechanical polishing pads are provided, wherein the shape memory chemical mechanical polishing pads comprise a polishing layer in a densified state. Also provided are methods of making the shape memory chemical mechanical polishing pads and for using them to polish substrates. | 10-15-2009 |
| 20100137554 | SHAPE MEMORY CYANATE ESTER COPOLYMERS - This disclosure covers a new methodology to produce high performance, high temperature, thermoset resins having shape memory characteristics based on cyanate ester resins. This methodology is based on pericyclic polycyclotrimerizations by utilizing a heretofore unknown polymerization mechanism based on equilibrium controlled condensation and cyclization. A mono-functional cyanate ester resin is reacted with at least one molecule terminated with a moiety containing an active hydrogen. One example of molecules with a moiety terminated with an active hydrogen are amine terminated dimethylsiloxane. The resulting compound is heated and reacted with a difunctional cyanate ester resin and cured. The Tg of the final Cyanate Ester SMP can be matched to specific requirements by adjusting the ratio of the previous said elements and/or the addition of other agents to adjust the physical properties of the final Cyanate Ester SMP. | 06-03-2010 |
