Title: System and method for detection of freefall with spin using two tri-axis accelerometers
Inventor: KIM DONG YOON
IPC: G06F15/00
Filed: 2008-03-27
Abstract: A system (10) and method detect freefall associated with an object that is spinning or tumbling as it falls. Two tri-axis accelerometers (14, 16) provide inputs to an algorithm (28) that detects the freefall of a spinning object that would not otherwise be detected by a conventional freefall detection system, due to the centrifugal and centripetal forces being placed on the falling object as it spins. The system can be used to detect the freefall of portable devices with onboard memory or hard disk drives, allowing the devices to have time to park the read/write head and reduce the potential of losing data that can be damaged by impact. This freefall detection system may be applied to such portable devices as notebook computers, PDAs, MP3 players, digital cameras, mobile phones and even automobiles.

Title: Method and system for introducing fuel oil into a steam reformer with reduced carbon deposition
Inventor: WHYATT GREG A
IPC: H01M8/04
Filed: 2008-04-08
Abstract: A system and method for creating reformate with decreased carbon deposition. The system is made up of a steam source, a superheater, a fuel injection device, a prereformer, and a reformer with catalyst linings. The system functions to superheat steam while maintaining the fuel at a lower temperature prior to injection and mixing with the steam.

Title: System for continuously using resist stripper liquid based on nanofiltration
Inventor: SUMITA MASANAO
IPC: H01L21/027
Filed: 2008-06-27
Abstract: [PROBLEMS] To realize a system in which a resist stripper liquid used in resist stripping is regulated so as to have a resist component concentration within a certain concentration range even when the resist stripper liquid is continuously used for long without replacing it. [MEANS FOR SOLVING PROBLEMS] In stripping a positive resist with a stripper liquid, the resist components which have dissolved in the stripper liquid can be diminished by cross-flow filtration with a specific ceramic filter (5). In the resist stripping system, a resist-component-containing stripper liquid resulting from a stripping step is treated in a filtration step, and the resultant concentrated stripper liquid having a heightened resist-component concentration is suitably discharged from the system. A fresh stripper liquid is suitably added to the stripper liquid from which the resist components have been removed, and the resultant stripper liquid is reused in the stripping step.
