  • Publication number: 20080150640
    Abstract: A spin oscillator device generates a microwave output in response to an applied DC current. The device includes a spin momentum transfer (SMT) stack including a top electrode, a free layer, a nonmagnetic layer, a pinned magnetic structure, and a bottom electrode. A local magnetic field source adjacent the SMT stack applies a local magnetic field to the free layer to cause the magnetization direction of the free layer to be oriented at a tilt angle with respect to plane of the free layer. The local magnetic field source can include coils or an electromagnet structure, or permanent magnets in close proximity to the SMT stack.

  • Patent number: 7390584
    Abstract: A ferromagnetic thin-film based magnetic device with internal film coupling compensation including a nonmagnetic material intermediate layer with an initial thin-film of an anisotropic ferromagnetic material on one side. A compensation thin-film of an anisotropic ferromagnetic material is provided on the opposite side with an antiparallel coupling layer thereon and a subsequent thin-film of an anisotropic ferromagnetic material on the antiparallel coupling layer with the compensation thin-film being less thick than the subsequent thin-film. A antiferromagnetic layer can be supported by the layers on either side of the intermediate layer.

  • Publication number: 20080133098
    Abstract: A braking control system and method for a vehicle improves vehicle stability and steerability. When a braking torque is being applied and a road disturbance is detected, the braking torque may be reduced as the vehicle traverses the road disturbance. Subsequently, when the road disturbance has been traversed, the braking control system may allow the application of braking torque as requested by a braking device. The reduction in braking torque when traversing road disturbances minimizes the physical impact experienced by the vehicle wheels.

  • Patent number: 7066396
    Abstract: A heating system having a steam generator or water heater, at least one economizer, at least one condenser and at least one oxidant heater arranged in a manner so as to reduce the temperature and humidity of the exhaust gas (flue gas) stream and recover a major portion of the associated sensible and latent heat. The recovered heat is returned to the steam generator or water heater so as to increase the quantity of steam generated or water heated per quantity of fuel consumed. In addition, a portion of the water vapor produced by combustion of fuel is reclaimed for use as feed water, thereby reducing the make-up water requirement for the system.

  • Patent number: 6872467
    Abstract: A ferromagnetic thin-film based magnetic field sensor having a nonmagnetic intermediate layer with two major surfaces on opposite sides thereof upon one of which a magnetization reference layer is provided and upon the other there being provided a sensing layer. A spacer layer is provided on the sensing film to separate this sensing film from an augmenting film with the spacer layer being sufficiently thick so as to significantly reduce or eliminate topological coupling between the sensing and augmenting films, and to significantly randomize spin states of emerging electrons traversing therethrough.

  • Patent number: 6777730
    Abstract: A ferromagnetic thin-film based digital memory having a plurality of bit structures electrically interconnected with information storage and retrieval circuitry that avoids information loss in one bit structure because of operating the others through this circuitry. Each of these bit structures formed of a relative orientation maintenance intermediate layer having two major surfaces on opposite sides thereof with a pair of memory films of an anisotropic ferromagnetic material each on a corresponding one of said relative orientation maintenance intermediate layer major surfaces. The relative orientation maintenance intermediate layer is of a material and a selected thickness so as to maintain magnetizations of said memory films oriented in substantially opposite directions.
