Information is transferred from the first communication module to the second communication module via the magnetic field.
摘要:
A method and apparatus for humidifying residential and commercial buildings in which a flue gas generated by a residential or commercial furnace is provided to one side of a porous liquid water transport membrane and habitable space air is provided to an opposite side of the porous liquid water transport membrane in an amount sufficient to provide a habitable space air to flue gas volume flow rate ratio of at least 8.3:1. At least a portion of the water vapor in the flue gas is condensed, providing condensed liquid water which is passed through the porous liquid water transport membrane to the habitable space air side of the porous liquid water transport membrane. On the habitable space air side of the membrane, the condensed liquid water is evaporated into the habitable space air, producing humidified habitable space air which is provided to the rooms of the residential and commercial buildings. Beneficially, no supplemental water source is required for the humidification process.

A tire cornering power estimation and monitoring system may include a steering torque sensor, a steering wheel angle sensor, a yaw rate sensor, a lateral acceleration sensor, and a speed sensor. The system may further include at least one controller configured to receive signals from the steering torque sensor, steering wheel angle sensor, yaw rate sensor, lateral acceleration sensor, and speed sensor and send a notification if the signals indicate that one or more of the vehicle's tires need to be checked or serviced. The system may further include a notification system configured to receive a signal from the controller and indicate that one or more of the vehicle's tires need to be checked or serviced.
摘要:
A method for steering pull compensation to maintain a steering load below a predetermined threshold value. A straight line driving condition is verified through vehicle sensors and/or GPS, drive torque control is performed such that the steering load is kept below the predetermined threshold value. The steering pull compensation method may be disabled by a vehicle operator and is disabled in the absence of a verified straight line driving condition.

A magnetic memory unit includes a tunneling barrier separating a free magnetic element and a reference magnetic element. A first phonon glass electron crystal layer is disposed on a side opposing the tunneling barrier of either the free magnetic element or the reference magnetic element. A second phonon glass electron crystal layer also be disposed on a side opposing the tunneling barrier of either the free magnetic element or the reference magnetic element to provide a Peltier effect on the free magnetic element and the reference magnetic element.

Magnetic tunnel junctions having a specular insulative spacer are disclosed. The magnetic tunnel junction includes a free magnetic layer, a reference magnetic layer, an electrically insulating and non-magnetic tunneling barrier layer separating the free magnetic layer from the reference magnetic layer, and an electrically insulating and electronically reflective layer positioned to reflect at least a portion of electrons back into the free magnetic layer.
摘要:
A method and apparatus for stray magnetic field compensation in a non-volatile memory cell, such as a spin-torque transfer random access memory (STRAM). In some embodiments, a first tunneling barrier is coupled to a reference structure that has a perpendicular anisotropy and a first magnetization direction. A recording structure that has a perpendicular anisotropy is coupled to the first tunneling barrier and a nonmagnetic spacer layer. A compensation layer that has a perpendicular anisotropy and a second magnetization direction in substantial opposition to the first magnetization direction is coupled to the nonmagnetic spacer layer. Further, the memory cell is programmable to a selected resistance state with application of a current to the recording structure.
