20140190771 | PULSED PLASMA LUBRICATION DEVICE AND METHOD - Disclosed herein is a lubrication device comprising a solid lubricant disposed between and in contact with a first electrode and a second electrode dimensioned and arranged such that application of an electric potential between the first electrode and the second electrode sufficient to produce an electric arc between the first electrode and the second electrode to produce a plasma in an ambient atmosphere at an ambient pressure which vaporizes at least a portion of the solid lubricant to produce a vapor stream comprising the solid lubricant. Methods to lubricate a surface utilizing the lubrication device in-situ are also disclosed. | 07-10-2014 |
20080250118 | SYSTEMS, METHODS, AND APPARATUS OF A SPACE COMMUNICATION FILE TRANSFER SYSTEM - Systems, methods and apparatus are provided through which in some embodiments a CFDP protocol state machine and state table is implemented on each of a number of entities in a space communication system. Some embodiments of the state table specify at least one action to specific events for each of a plurality of possible states and each state table implements a core CFDP protocol. In some embodiments a method to transfer data into and out of space flight systems and/or ground systems includes receiving a user request into a memory of a CFDP-compliant library apparatus. The method also includes starting a state machine in the memory of the CFDP-compliant library apparatus that prompts a core protocol to transfer a specified file to and/or from a specified destination and initiating transfer of data blocks from the memory of the library apparatus. | 10-09-2008 |
