Abstract: Method and apparatus for attaching an electrical component to a printed circuit board. The apparatus includes a circuit board, an elastomeric connector, a rotary electrical component having a connector housing for holding the elastomeric connector, and one or more fasteners for securing the electrical component to the circuit board with sufficient force to compress the elastomeric connector and thereby ensure electrical contact between the electrical component and the printed circuit board.

Abstract: A sealed cabled assembly includes a cable and a cable moisture seal assembly. The cable includes a cable subcore, a metal shield layer surrounding the cable subcore, and a jacket surrounding the metal shield layer. The cable subcore includes an electrical conductor surrounded by an electrical insulation layer. The cable moisture seal assembly includes a sealant, a electrically conductive jumper member, and an outer sleeve. The cable includes a sealing region section extending from a first axial end to a second axial end, and in which a section of the jacket and a section of the metal shield layer are removed to expose a section of the cable subcore. The insulation layer and the conductor extend through the sealing region section. First and second sections of the jacket extend away from the sealing region section in first and second opposed directions, respectively.

Abstract: An autonomous unmanned space flight system and planetary lander executes a discrete landing sequence including performing an initial velocity braking maneuver to remove velocity at altitude, coasting during which the planet surface is imaged and correlated to reference maps to estimate cross-track and along-track navigation errors and one or more lateral braking maneuvers are performed to reduce cross-track navigation error, and performing a terminal velocity braking maneuver(s) to reduce the along-track braking maneuver and remove the remainder of the velocity just prior to landing. A bi-propellant propulsion system provides a very high T/M ratio, at least 15:1 per nozzle. Short, high T/M divert maneuvers provide the capability to remove cross-track navigation error efficiently up to the maximum resolution of the reference maps.

Abstract: The crystal structure of the product, crystals of the MarR protein, a regulator of multiple antibiotic resistance in Escherichia coli, and methods of crystallization of the MarR protein are described.

Abstract: An elongated T-nut fastener is formed from a single piece of material. The fastener includes a barrel and a flange, with a threaded portion in the barrel and an unthreaded portion beyond the threaded portion. Fastening sites are provided at spaced locations along the length of the fastener.
