Abstract: A relocation system to associatively search a database lookup table with a search key to addressably retrieve a corresponding associate content table record as a search result. The relocation system is implemented in search engine devices having associative memory (e.g., CAM) having one or more sections. The search engine devices employ relocation values when calculating addresses, one per section per device, with the relocation values optionally pre-calculated and stored in relocation registers. The search engine devices may be cascaded to construct a larger search engine. The search engine is typically used with a processor and addressable memory (e.g., RAM or ROM). In particular, the relocation system permits multiple databases to be concurrently stored and worked with in the associative and addressable memory.

Abstract: A method for reducing the starting time and reducing the peak phase currents for an internal combustion engine that is started using an induction machine starter/alternator. The starting time is reduced by pre-fluxing the induction machine and the peak phase currents are reduced by reducing the flux current command after a predetermined period of time has elapsed and concurrent to the application of the torque current command. The method of the present invention also provides a strategy for anticipating the start command for an internal combustion engine and determines a start strategy based on the start command and the operating state of the internal combustion engine.

Abstract: A method (10, 30) for actively controlling the temperature (tmotor) of an electric machine operating under torque (T*), speed and/or position control. A controlled output (T*), i.e. torque command, voltage, current or power, is adjusted such that the temperature of the electric machine does not exceed a predetermined reference limit (tref). The method (10, 30) of the present invention performs proportional-integral control (14) to reduce the commanded output (T*) to the motor and thereby prevent the steady-state motor temperature (tmotor) from increasing beyond the predetermined limit (tref). In one embodiment of the method (10), an error term (e) is filtered through a negative pass filter (12) before being combined with an optional decay term (&egr;decay) in a proportional-integral controller (14). A positive pass filter (20) and a negative pass filter (22) provide outputs that are summed and provide an adjusted output command (Tlimited) based upon predetermined relationship.
