    Abstract: In general, the invention is directed to techniques for reducing the amount of switching current that is utilized within a magnetic storage (e.g., MRAM) device. An example apparatus includes a fixed magnetic layer that provides a fixed direction of magnetization, an exchange-coupled magnetic multi-layer structure, and a non-magnetic layer placed between the fixed magnetic layer and the exchange-coupled magnetic multi-layer structure. The exchange-coupled magnetic multi-layer structure includes a recording layer configured to record information and an assisting layer having a lower anisotropy than the recording layer. The exchange coupling between the recording and assisting layers is operable to switch a magnetization direction of the recording layer. In some cases, the exchange-coupled magnetic multi-layer structure may further include a spacer separating the recording and assisting layers and configured to weaken an exchange coupling between the recording and assisting layers.

    Abstract: Powered mobility systems and methods are disclosed. A powered mobility system includes a mobile unit, a support frame, a plurality of markers, a motion capture device, and a processor. The mobile unit is operable to move the powered mobility system. The support frame is adapted to support a user. The plurality of markers are configured to be attached to the user. The motion capture device is configured to detect movement of the plurality of markers. The processor is programmed to receive signals from the motion capture device, translate the signals into instructions for moving the mobile unit, and transmit the instructions to the mobile unit. A powered mobility method includes placing a user in a support frame, attaching a plurality of markers to the user, detecting movement of the plurality of the markers, and generating movement of the mobile unit based on the movement of the plurality of the markers.
