Abstract: A stator for an electric machine comprises a cylindrical core defining an inner cylindrical surface and an outer cylindrical surface with a plurality of slots formed between the inner cylindrical surface and the outer cylindrical surface. Windings are positioned on the cylindrical core. The leads of the windings include a plurality of inner leads associated with conductors in an inner layer of the slots and a plurality of outer leads associated with conductors in an outer layer of the slots. A bus bar assembly includes a plurality of inner bus bars and a plurality of outer bus bars, the plurality of inner bus bars connected to the plurality of inner leads, and the plurality of outer bus bars connected to the plurality of outer leads. The plurality of outer bus bars are positioned radially outward from the end turns of the windings and radially inward from the outer cylindrical surface.

Abstract: A protection circuit is disclosed, for preventing access to stored security key data after the security key is no longer used. The protection circuit performs operations on a programming circuit used to program a bit of the security key. The protection circuit prevents inspection of the security key bit, using several techniques. Subsequent inspection of the programming circuit does not reveal the value of the security key bit.

Abstract: A method and system for dynamic file allocation is disclosed. In the system, an input device receives a data object which is sent to an allocation device. The allocation device is comprised of a publishing point which contains a virtual mapping system that directs the data object to an entry in the storage object.

Abstract: A memory driver architecture and associated methods are generally described.

Abstract: An oscillator that has a substantially-constant voltage source configured such that it does not require the voltage source to be tuned to a particular voltage to oscillate a particular frequency. The oscillator has greater precision and reliability since the inputs of the comparator are periodically switched to reduce the effects of comparator bias and to equalize the voltage stresses on the inputs of the comparator. Greater precision is also achieved through the use of a discrete resistor and a discrete capacitor to define the frequency of the oscillator. The present invention provides an oscillator and method to generate a periodic signal that is tamperproof because the circuitry that defines the period is either integrated onto the integrated circuit or contained within the package containing the integrated circuit.
