Abstract: A support apparatus may be formed from a single sheet of generally planar material that is cut to define the requisite frame and subparts, and the spaces to position those subparts during use and storage of the apparatus. The support apparatus, which may function as a sawhorse, may be purchased and/or delivered on site as a generally planar unit, the legs and pegs broken out from the frame and the whole apparatus assembled for use. Following use, the apparatus may then be dissembled and reconfigured back into a generally planar configuration for storage and/or transport.

Abstract: Methods and apparatus are provided for detecting leaks in a MEMS sensor package, and in particular, a MEMS sensor package that includes an oscillating structure or element that has a Quality (Q) value. The method and apparatus may include measuring the Q value of the MEMS sensor at a first time, applying a pressure to the outside of the MEMS sensor package, and measuring the Q value of the MEMS sensor at a second time after pressure has been applied for a period of time. A change in the measured Q values between the first time and the second time may be determined, which may then be correlated to a leak rate for the particular MEMS sensor package. In some cases, a leak rate of 2×10?13 He atm.cc/s or less may be detected.

Abstract: Carbon deposits on engine components can negatively affect engine performance. An engine of the present disclosure includes at least one carbon deposit resistant engine component attached to an engine housing. The engine component includes at least one relatively high surface tension surface that is a non-contact wear surface and to which a relatively low surface tension coating is attached. The relatively low surface tension coating has a surface tension at least one of equal to and less than 30 dyne/cm.

Abstract: An interactive defect reporting system is designed to handle enroute equipment problems and repairs in a paperless process that enables on-board personnel to report equipment problems using a phone. After calling the system, the on-board personnel describes the, problem in their own words in as much detail as necessary. The computerized reporting system assigns a unique Trouble Ticket number to the report and all subsequent repairs. Mechanics listen to the Trouble Tickets or have transcribed copies faxed to their facilities. Trouble Tickets are also immediately available to all downline maintenance facilities so that mechanics can prepared for problems on a train well in advance of its arrival. Once a problem is fixed, the mechanics called in the repair and describe in detail what was done to fix the problem. On-board personnel can listen to the repairs or request a fax copy of the Trouble Ticket.

Abstract: A sailing ski for use on snow and ice comprising an elongated body having substantially flat upper and lower surfaces, the lower surface having an upwardly extending camber, a universal mast mount for mounting a sail positioned toward the forward end of the elongated body, longitudinally spaced foot straps positioned rearwardly of the universal mast mount and overlying the camber area, and longitudinally spaced runners along the edges of the ski rearwardly of the foot straps and having a portion thereof projecting at least partly below the lower surface of the ski with the runners being in transversely spaced parallel relation.
