Filed:

Aug 13, 2009

Appl. No.:

12/541111

Inventors:

Randall H. Victora - New Brighton MN, US
Xi Chen - Minneapolis MN, US

Assignee:

Regents of the University of Minnesota - St. Paul MN

International Classification:

G11C 11/00

US Classification:

365158, 365171, 365173

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.

International Classification:

G10L 15/18
G06F 16/687
G10L 15/22

Abstract:

A speech processing system uses contextual data to determine the specific domains, subdomains, and applications appropriate for taking action in response to spoken commands and other utterances. Some applications may be given priority over others such that some applications are general request applications to which responsibility for processing an intent is to be assigned as long as contextual criteria are satisfied, while other applications are specific request applications to which responsibility for processing an intent is to be assigned only if the applications are specifically requested, if the contextual criteria of priority applications are not satisfied, and/or if certain contextual criteria associated with the specific request applications are satisfied.

Abstract:

Curable compositions for dynamic epoxy-based thermoset adhesives and/or sealants are provided. Methods of applying the compositions to form strong, low-stress, cured adhesive polymer films are also provided. The cured polymer films use crosslinkers that include disulfide and carbon-nitrogen bonds, wherein the disulfide bonds impart dynamic chemistry to the polymer network structure in order to the achieve adaptable thermoset adhesives and sealants.

Abstract:

The present concepts relate to matching data of two different modalities using two stages of attention. First data is encoded as a set of first vectors representing components of the first data, and second data is encoded as a set of second vectors representing components of the second data. In the first stage, the components of the first data are attended by comparing the first vectors and the second vectors to generate a set of attended vectors. In the second stage, the components of the second data are attended by comparing the second vectors and the attended vectors to generate a plurality of relevance scores. Then, the relevance scores are pooled to calculate a similarity score that indicates a degree of similarity between the first data and the second data.
