In 2004, LHAs were used to transport thousands of Marines and their equipment to Iraq and Afghanistan for combat operations. LHA 6 was placed under contract in June 2007 with NGSB. LHA 6 will be an aviation-centric modified repeat of the USS Makin Island, LHD 8 and is scheduled for delivery to the Navy in 2013.
Phase-change memory (also known as PCM, PCME, PRAM, PCRAM, Ovonic Unified Memory, Chalcogenide RAM and C-RAM) is a type of non-volatile random-access memory.PRAMs exploit the unique behaviour of chalcogenide glass.his burst of voltage is provided by a charge pump, which takes some time to build up power. General write times for common Flash devices are on the order of 0.1ms (for a block of data), about 10,000 times the typical 10 ns read time, for SRAM for example (for a byte).
The reason for the computer supplying a bias voltage is for diagnostic purposes. O2 Sensor Diagnostics. As I just discussed, the computer supplies a bias voltage signal to the O2 sensor any time the key is on. This is done so the computer can monitor if the O2 sensor is warm enough to start operating.As mentioned before, a cold O2 sensor outputs no voltage signal.he O2 sensor is one of the most vital sensors used on the engine. It is responsible for helping the computer make adjustments to the fuel mixture (air/fuel ratio, or AFR) delivered to the engine.
