An Ocean Thermal Energy Conversion (OTEC) system having a turbine with an upstream side and a downstream side. Warm water under a partial vacuum is converted into a vapor, the vapor being supplied to the upstream side of the turbine at a pressure controlled by the temperature of the warm water. A condenser is situated on the downstream side of the turbine to cause the vapor, after passing through the turbine, to undergo a phase change back to a liquid, which can be used as potable water. The condenser is coupled to a source of a cooling liquid, and the pressure of the vapor on the downstream side of the turbine is determined by the temperature of the cooling liquid. A flexible floating solar collector supplies the warm liquid to the upstream side at a temperature higher than normal ambient temperature.

A method for computer memory calibration includes flashing a calibration from a processor into two flash memory sections. Either the same or an alternate processor requests data stored in one of the flash memory sections. Subsequently, exception handler logic within an exception mechanism activates and generates an exception for the data stored in the aforementioned flash memory section. The calibration in the other flash memory section then transfers to the processor through the functioning of the exception.

Method, control system and computer-readable medium are respectively provided for determining angular crankshaft position prior to a cranking event of an internal combustion engine. Upon issuance of an engine shutdown command, the method allows determining an initial crankshaft position based on a crankshaft position sensor. The method further allows providing a rulebase for relating angular travel of a rotor in an accessory device to crankshaft angular travel. Angular travel of the rotor in the accessory device is sensed since issuance of the engine shutdown command until the engine reaches a resting position. The rulebase is accessed to relate the value of the angular travel of the rotor in the accessory device to crankshaft angular travel and provide an incremental crankshaft angular travel relative to the initial crankshaft position at engine shutdown. Crankshaft position is calculated at the resting position based upon the initial crankshaft position plus the incremental crankshaft angular travel based on the angular travel of the rotor in the accessory device. The calculated crankshaft position corresponding to the resting position is stored. Upon issuance of an engine re-start command, the stored crankshaft position corresponding to the resting position is retrieved to provide quick and accurate engine control regardless of any dead-band in the crankshaft position sensor during low engine speeds.
