Abstract: Embodiments of the invention include an inspection system to inspect internal components of a compressor of a gas turbine engine. The inspection system includes an image recording assembly having one or more image recording devices, light sources, storage devices, and power supplies. The image recording assembly may be inserted into a compressor without removal of the compressor housing or disassembly of the compressor. The image recording assembly may be removably coupled to a rotary component of the compressor, e.g., a rotor blade, and used to record images of stationary components, e.g., stator vanes, of the compressor. The images may be inspected to identify wear and/or defects in the stationary components, e.g.

Abstract: A method for archiving a log for a data storage system includes the steps of logging host inputs/outputs to the log, creating a snapshot of the log when it is full, resetting a next write offset to the start of the log after the snapshot is created while continuing the logging to the log, performing copy-on-write of the log to the snapshot, and archiving the snapshot to an archived log.

Abstract: A method for resynchronizing a first copy of data on a first storage system from a second copy of the data on a second storage system includes, at a regular checkpoint interval, the first storage system pushing data in its cache that were modified prior to a checkpoint time to its nonvolatile storage and saving the checkpoint time to its nonvolatile storage. The method further includes, at a regular snapshot interval greater than the checkpoint interval, the second storage system taking snapshots of the second copy of the data. When the first storage system has an uncontrolled shutdown, the second storage system determines the snapshot closest in time to the last checkpoint time and sends the difference between the last snapshot and the second copy of the data to the first storage system to recover data lost during the uncontrolled shutdown.

Abstract: A semiconductor device which has a resistor, a capacitor, a Schottky diode, and an ESD protection device all formed on a single semiconductor substrate. The resistor and the capacitor are coupled together in series. The Schottky diode and the ESD protection device are coupled in parallel to the series connection of the resistor and capacitor.

Abstract: A semiconductor device which has a resistor, a capacitor, and a Schottky diode all formed on a single semiconductor substrate. The capacitor comprises a dielectric region between two metal regions. The resistor comprises an N.sup.+ -type well. The Schottky diode comprises an N-type tub, a metal region in contact with the tub, and an N.sup.+ -type region formed in the N-type tub. The resistor and capacitor are coupled by a metal region which contacts one of the metal regions of the capacitor and the N.sup.+ -type well of the resistor. The resistor and Schottky diode are coupled by a metal region which contacts the N.sup.+ -type well of the resistor and the N.sup.+ -type well of the Schottky diode.
