In a related embodiment, the polymer defines a thermoplastic polymer having a glass transition temperature. The apparatus can comprise of a chamber, and input manifold, an exhaust manifold, a solvent reservoir and a gas reservoir. The solvent reservoir provides one or more solvent systems adapted to chemically bind, and potentially react, with the polymer. The gas reservoir provides one or more gases for drying the substrate and printed polymer after the solvent treatment step. In one application, a substrate having printed surface thereon is placed in the chamber and exposed to the solvent system for sufficient period of time to provide substantially flat print surfaces. | 08-25-2011 |
20140340522 | STAR TRACKER WITH STEERABLE FIELD-OF-VIEW BAFFLE COUPLED TO WIDE FIELD-OF-VIEW CAMERA - A star tracker has an electronically steerable point of view, without requiring a precision aiming mechanism. The star tracker can be strapped down, thereby avoiding problems associated with precision aiming of mechanical devices. The star tracker images selectable narrow portions of a scene, such as the sky. Each stellar sighting can image a different portion of the sky, depending on which navigational star or group of navigational stars is of interest. The selectability of the portion of the sky imaged enables the star tracker to avoid unwanted light, such as from the sun. | 11-20-2014 |

20110069929 | Methods for Passively Aligning Opto-Electronic Component Assemblies on Substrates - A method for aligning an opto-electronic component assembly (OECA) on a substrate includes positioning a substrate on an assembly surface and positioning an OECA on the substrate such that a first OECA alignment face projects from a first substrate alignment face. The substrate and the OECA are advanced towards a contact face of a first assembly alignment mechanism such that the first substrate alignment face contacts the contact face of the first assembly alignment mechanism after the first OECA alignment face contacts the contact face. The OECA is displaced relative to the first substrate alignment face when the first OECA alignment face contacts the contact face and the substrate continues to move towards the contact face thereby aligning the OECA on the substrate relative to the first substrate alignment face. | 03-24-2011 |
